What is an oleo strut in landing gear?

An oleo swagger is a pneumatic air–oil water-powered safeguard utilized on the setting down stuff of most enormous airplanes and numerous more modest ones. This plan pads the effects of landing and damps out vertical motions.

What is shock-absorbing landing gear?

Stun Absorbing and Non-Shock Absorbing Landing Gear 

This is done two: 1) the stunning energy is adjusted and moved all through the airframe at an alternate rate and time than the single solid beat of effect, and 2) the stun is consumed by changing over the energy into heat energy.

Which is better to use the landing skid?

Which one is better relies upon the mission the helicopter is performing. The slide landing gear is basic and lighter weight, so it is the most ideal decision for little helicopters as weight is consistently a thought. Additionally, slide landing gear needs almost no support, however, the downside is that ground taking care of is more troublesome.

Why is landing gear retracted?

Planes that have retractable stuff by and large withdraw their stuff for improved execution. Not having haggles hanging down smoothes out the plane, improves eco-friendliness, empowers them to fly quicker and higher, and makes for a calmer, more agreeable ride inside the lodge.

Landing Gear and Types – Shock Strut Operation and Servicing

Retractable landing gear comprises of a few parts that empower it to work. Regularly, these are the force connections, trunnion, and section plans, drag swagger linkages, electrical and water-driven stuff withdrawal gadgets, just as locking, detecting, and showing parts. Moreover, nose gear has directing components appended to the stuff. 

As recently referenced, a force arm or force connects gathering keeps the lower swagger chamber from turning twisted with the longitudinal pivot of the airplane. In some swagger gatherings, it is the sole method for holding the cylinder in the upper swagger chamber. The connection closes are joined to the fixed upper chamber and the moving lower chamber with a pivot pin in the middle to permit the swagger to broaden and pack. 

Arrangement of the wheels of an airplane is additionally a thought. Ordinarily, this is set by the producer and just requires incidental consideration, for example, after a hard landing. The airplane's fundamental wheels should be investigated and changed, if important, to keep up the appropriate tow-in or tow-out and the right camber. Tow-in and tow-out allude to the way a principle wheel would take according to the airframe longitudinal pivot or centerline if the wheel was allowed to move forward. Three prospects exist. The wheel would roll either: 1) corresponding to the longitudinal pivot (adjusted); 2) meet on the longitudinal hub (tow-in), or 3) veer away from the longitudinal hub

The maker's support directions give the strategy for checking and changing tow-in or tow-out. An overall strategy for checking arrangement on a light airplane follows. To guarantee that the arrival gear settles appropriately for a tow/close behind out test, particularly on a spring steel swagger airplane, two aluminum plates isolated with oil are put under each wheel. Delicately rock the airplane on the plates to make the stuff discover the very still position liked for arrangement checks. 

A straight edge is held across the front of the fundamental wheel tires just beneath hub tallness. A woodworker's square positioned against the straight edge makes an opposite that is corresponding to the longitudinal pivot of the airplane. Slide the square against the wheel get together to check whether the forward and rearward areas of the tire contact the square. A hole in front demonstrates the wheel is towed-in. A hole in the back demonstrates the wheel is towed out.

Landing Gear and Types – Shock Strut Operation and Servicing

represents the internal development of a stun swagger. Bolts show the development of the liquid during pressure and expansion of the swagger. The pressure stroke of the stun swagger starts as the airplane wheels contact the ground. As the focal point of mass of the airplane moves descending, the swagger packs, and the lower chamber or cylinder is constrained upward into the upper chamber. The metering pin is in this way climbed through the opening. The shape of the pin controls the pace of the liquid stream from the base chamber to the top chamber at all focuses during the pressure stroke. As such, the best measure of warmth is dispersed through the dividers of the swagger. Toward the finish of the descending stroke, the packed air in the upper chamber is additionally compacted which restricts the pressure stroke of the swagger with negligible effect. During taxi activities, the air in the tires and the swagger join to streamline knocks.

Deficient liquid, or air in the swagger, cause the pressure stroke to not be appropriately restricted. The swagger could reach as far down as possible, bringing about effect powers to be moved straightforwardly to the airframe through the metallic construction of the swagger. In an appropriately overhauled swagger, the augmentation stroke of the stun swagger activity happens toward the finish of the pressure stroke. The energy put away in the compacted air in the upper chamber makes the airplane begin moving upward comparable to the ground and lower swagger chamber as the swagger attempts to bounce back to its ordinary position. The liquid is constrained down into the lower chamber through limitations and reprimanding holes. The scorning of liquid stream during the expansion stroke hoses the swagger bounce back and lessens wavering brought about by the spring activity of the packed air. A sleeve, spacer, or guard ring fused into as far as possible the expansion stroke.

How does Auto Pilot function in an Aircraft? | Modes of Operation | Auto Flight System

Hello and welcome we will be looking at what is autopilot and how it controls and aircraft what is an autopilot the autopilot is a system that is used to control any graph with little or no input from the pilot When the autopilot is increased it is responsible for keeping their graphs table on all three axes it may also be responsible for dieting day aircraft open point autopilot reduces a pilot workload which is extremely helpful in long-distance flight and also in flying aircraft safety especially in the weather so if there is any disturbance in rule autopilot is responsible to bring back to original attitude them over a particular flight plan with the assistance of the control surfaces after the autopilot is turned on the pilot are responsible for monitoring the operation of the autopilot

What is autopilot and how it works?

in Ottapalam is coupled with the climate control directly Autopilot is mainly responsible in India ka table if there are any disturbances autopilot services required to bring back to its attitude in big day craft the autopilot will be coupled with flight control computer the navigation beautiful and even with auto the autopilot is responsible table on all the three Axes in case of any disturbances during flight it will detect a disturbance based on changes in attitude what the height of the aircraft the autopilot will take corrective action and bring back to its original like profile but sending information to different type control computer the autopilot is responsible for guiding the particular route this pre planned route of life plan would have been inserted by the balance in the autopilot computer autopilot information from the navigation computer to determine the position and to adjust the direction for altitude at which the aircraft is required to fly this is done by sending information to different like control computers to move different flight control surfaces so the balance only to monitor the functioning of the autopilot the autopilot also be coupled with autotrust function function is used to it just that Indians phone increasing or decreasing the aircraft speed this is extremely helpful for performing an auto land with help of an instrument landing system for Ireland the autopilot will control the aircraft to get your local icer and that lies looking and the hotel will adjust the speed to maintain the correct improve speed 

Modes of operation of the autopilot?

Autopilot can be operated in two modes manual mode and automatic mode in manual mode pilot to continuously provide inputs that the heading on the speed at which a craft needs to fly this input will be sent to the Ottapalam and order the computer which will control the accordingly the balance will receive this instruction from the etc during flight these inputs will be used for short duration only for most of the flight time the automatic mode is used in automatic mode the flight plan with boss insert into the autopilot computer I used as reference the flight plan will have information such that the headache and the speed at which sea a graph fly this information are taken by the autopilot and the onto the system and used to kindly grant know the balance just have to monitor the operation of the autopilot and take action if any false so

What's another word for autopilot?

how to monitor the autopilot operation after the autopilot is increased it will inform the balance on how the aircraft is being blown through the flight mode annunciator on the FM mein the atom is located on the top of the primary flight display or TFT and is something that the pilot should monitor throughout the entire duration of the flight along with the information on the PFD and the navigation.

Well, pilots needed in the future?

recently made a flight with the aircraft took off on its own this ongoing project which is known as a tt open which transfer autonomous taxi takeoff and landing which means the developing airplanes which can take of land and also even taxi on the ground on their own without any pilot inputs that obviously brings up the question that what is the palace to incorporate them and in the future will find it even be required in the corporate and today in army advance that question for all of you

About the future because to talk about what is happening right now in today's date what level of automation do we have on most commercial airplanes about the big commercial onesand not the small ones upon once they do not have a defined as they have very basic order pirates the modern commercial big one that you guys are usually fly on when you are going on a flight those airplanes are all very automatic even right now they all have something on autopilot which is nothing more than a computer which operates the aircraft in accordance to the Pilots inputs are the Pilots inputs are not physically inputs to the controls that will tell the autopilot to do something I want my aircraft to let se climb to operating altitude so I have a pilot will tell the autopilot by the rotating at idle for punching in a few numbers that you need to plan the altitude of the autopilot will automatically create of which of and client that altitude and only that altitude their level of and maintain that particular site that is a very basic function of an order pilot order by descend and also maintain a portal heading a particular they can also maintain rules the Loft Acropolis can do right now as well however as of date no airplane has an autopilot used in take it off Taking off an aeroplane always Number The Pilot is flying aircraft manually he have the controls in his hands and he is doing the rotation and everything and aircraft is totally in the pilots  hand And however there are Aircraft which can land automatically most of the big commercial airplanes all can land automatically airplanes are multiple autopilot could have to worry 13 autopilot and the odd couple together and they work together and make the aircraft follow the Except for the required to run on the Runway The Pilot is just sitting there and monitoring everything the finest of is less offline the airplane and it's more of monitoring systems these systems can make a graph land absolutely safely on the Runway and exactly on the Runway Centre line without any input from the Pilots to usually on a flight your after takeoff they will rotate the act of manually Airborne and after particular site which is different for each aircraft in engage the autopilot unless someone was the time and then you can do that as well but mostly after takeoff which is engaged to autopilot and let the operator to stop when you just sit there and monitor the system can show you can guess that the role of a pilot is in the future and even now more of a manager in the cockpit.

rather than actual flying back in the days when airplane for just introduced the pilot was there to fly the airplane they would have to controls in the hands and you just actually fly the aircraft has automation has improved pilot survey now reduced or shifted to a managerial role in the cockpit another job is to manage everything manager situations and manage the cockpit and let the automation and your device to the job of life now this is very nice there is nothing wrong with that I know it sounds negative that it never the same path but honestly it is is very good I'll tell you the reason why you're doing a flight from India to the US it's a very long flight 14 16 hour flight you can't expect the pilot to set and flying Aircraft for 16 hours and so you can imagine that would be very very tiring also in case something goes wrong in the cockpit then you have to manage a lot of things there are a lot of systems that can go on a lot situations can develop and to manage two situations if you have a autopilot which is helping you out and explain the aircraft which we see your mind free to concentrate and resolve the problem and concentrate on fly in the aircraft safety is increased automation is reducing pilot fatic and its improving safety standards and that  brings me to the Future what is can happen in the future as per the programme by Airbus ATTOL program they have initially as of now on the  the Airbus a350 tested automatic take off in the coming time  they will be also testing automatic taxi as well as automatic learning picture of be there have to the automatic takeoff thing they put up image sensors in front of the aircraft basically gift craft its own eyes and aircraft can recognise the centre line and then automatically maintain it so line up a graph with Ranway Centre line and earth crust and engage the autopilot  the autopilot will strengthen the centre line at maintaining the language centre line When you reach the rotation speed if the speed at which is bigger na take off and we begin our rotation of the ground reaching that Speed The autopilot Automatic leading the aircraft nose up and get the aircraft airborne eventually sometime down the line and bustle also be testing automatic taxi with the Pilots will just have to tell the aircraft the taxi on this fact that accident on that if I'm not that page and automatically to it all of this does it mean Pilots will not be required absolutely not all of these automation which are being introduced they are being done for two reasons like I said to reduce pilot fatig and measuring the main reason is to improve  flight safety more the automation you have more safe for operations become because we are humans are always prone to errors there are chances of human error happening computer properly program and with proper inputs will produce an excellent results as a result 20 Automations are helping of the Pilots to improve the operation of the aircraft.

What is reverse thrust in aircraft?| How does reverse thrust work?| What are the two types of thrust reverser?

Hello and welcome to text a revolution in this Blog we will be looking at which type of thrust reverser is fitted to the? what is meant by the trust was a system the types of thrust reversers? how did the services are deployed and the conditions that need to be satisfied for trust was a deployment?

What is reverse thrust in aircraft?

what is meant by a disaster was a system that is one of the systems that is installed on the engines normally on a graph the force that is acting in the forward direction is called as discussed force The thrust washer is used to create a backward force on the aircraft this is mainly used during landing on in case of a reject take off with the thrust reverser I used along with the brakes and spoilers in order to stop the aircraft on the runway if we consider but open engine thrust force is produced by pushing the air that is entering the engine backwards the trustable system creates a backward force by pushing the air that is entering the engine forward depending on the time of The thrust reverser system the bypass or both the bypass and the core may be pushed forward as soon as the aircraft lands on the Runway the cluster buses are deployed in order to increase the drag force that is active on the aircraft the trust versus I used along with the brakes and the ground spoilers in order to reduce the speed of the aircraft until it reaches a safe speed for taxing depending on the type of engine that different types of the services that I installed on the Jack and low bypass

Which type of thrust reverser is fitted to the turbofan Engines?

turbofan Engines clamshell on target type of thrust reverser is used these services are also called as bucket type reverses they will reflect the air coming from the core and the bypass junction forward to create the backward force in high bypass turbofan engine block a dose for translating sleeve type cluster buses are installed in these services only the bypass is put forward and the air from the code section continues to be pushed back word in Turbo props reverse Thrust is created the adjusting the pitch of the propeller to change the air flow direction now let's see what are the requirements for the trust was a system for the trust was a system to operate trust liver input from the cockpit hydraulic system and signal from the landing your computer are required in the cockpit to deploy the customers the bus Lever has to be brought to a while and then put for the back in summer craft a separate Lever may be provided to set reverse thrust the reverse Thrust is selected as soon as the main landing you touch the ground during landing in case of a reject 1 of the reverse is immediately selected and the takeoff is aborted similar to forward just application that reverse thrust also be adjusted reverse thrust may be increased from rivers Hydel power to maximum reverse power by moving the levers for the back maximum rivers trust will be used initially to reduce the speed of the aircraft but they can be certain speed limitations that are mentioned and till which maximum reverse can be used this is to avoid for in 1 damage on the engines trust was a deployment is a help of hydraulic power the hydraulic system that is installed on the aircraft provides the required hydraulic pressure 

How does reverse thrust work?

for The thrust reverser actuator if the aircraft has more than one hydraulic system then each reversal would be provided with separate hydraulic power this is because in case of failure of one of the hydraulic systems only one traversal will be affected the trustable the deployment of the depends on the landing a computer this is because the landing your computer has to send a signal that the main landing gears 5 touch the ground this is because the thrust reverser should be used only when the aircraft is on the ground so if reverse Thrust is selected when the aircraft is implied the landing a computer will sense that the landing gear has not touch the ground and will not allow the customers to deploy what would happen if the customer was a locking mechanism fails in KG thrust reversers get unlock when the aircraft is on flight on ground and the crew did not selected then the engine control unit will immediately reduced interest on that engine to idle trust can The thrust reverser be used to reverse anagram this is also called as power back but normally the customer so cannot be used for reversing an aircraft this is because many precautions need to be taken and it will burn a lot of you since the engines and decide to produce forward and reverse Thrust is produced mainly to slow down the aircraft

How does a turboprop engine work?| What planes use turboprop engines?| What is the difference between a turboprop and a turbofan engine?

Hello and welcome in this Blog we will be looking at the basics of the turboprop engine first let's take a look at the different types of gas turbine engines which can be installed on a graph we can have low budget turbofan from and to turboprop engines in this Blog

How does a turboprop engine work?

we will look at the entrance as shown on this aircraft we will see how the process created the basic construction of the prevention and why they are used on smaller short-range aircraft first let's see the principle of Trust generation on the top of an engine and a top off India if we apply Newton's second law that does force is equal to the mass of air entering the acceleration now if we consider auto financial a small mass or quantity of air enters engine which is accelerated too much higher value inside the engine causing an increase in the thrust force If we consider turboprop aircraft we have a propeller which creates the thirst a large quantity of air for the mass of air is accelerated by a small and you which causes an increase in the thrust force so when Adobe open the trust can be increased by increasing the acceleration of a but in a turboprop, there is a limitation on the mass of air being accelerated so it produces.

Why are turboprops still used? and What planes use turboprop engines?

the turboprop engine can be divided into two major sections then gen core which is similar to a gas turbine engine and the propeller which is connected to turbine driven shaft let's look at this sections in more detail the engine Core this consists of a compressor which is used to compress BA all to increase the pressure of the Year report and for competition then we have the combustor which consists of humours of igniters and combustion Chambers here fuels grade which mixes with the high pressure and get point inside the combustion chamber in the combustion chamber the pressure and the temperature of the gases increases the high pressure gases and then allowed to expand in the turbine section which causes the turbine to rotate this will cause the compressor to rotate these components are similar to gas turbine engine honour turboprop engine there is an additional term called as described above the gases expand further causing a decrease in the pressure and the rotation of the top and this turbine extracts on most of all the pressure energy from the incoming gases so very little trust is generated at the exhaust the stuff and rotates at a very high speed so it cannot be connected directly to the propeller at this will cause the place to stall so the turbine is connected to reduction gearbox this reduces the speed of the sharp so the propeller operates more efficiently now we will look at the propeller section the propeller consists of a series of air Ram feather power flight and reverse

What are the advantages of a turboprop?

force is created on this engine as the drive top and rotates text access to the energy from the high pressure gases so very little card is created at the exhaust the time and route is the propeller which creates most of the task force on the second round approximately 80% of the total cost is created by the propellers and 20% of the total Thrust is created by the exhaust gases simple comparison between having trouble propane and having trouble how to book Pro since most of it is created by propellers ditto properties are more efficient when operated at lower altitude where the density of air is more when compared to higher altitudes created by auto prop is lesser than did the fun and so the anchor 9 speed are slower across with the help of engine can take off and landowners Mona runway but the biggest advantage of Adobe Pro is that the fuel consumption is much less when operated on short routes this means less operating cost for the company so the turboprop aircraft can be found on smaller shot with actor as the most efficient for this kind of operations

Hello and Welcome what is meant by the Stabilized approach of an aircraft before we look at what is meant by a stabilized approach let's look and why an established approach is required for the advantages of waste plastic Road if the approval is developed it in a safe landing on aircraft which is landing at the correct speed and attitude text approach the completion of the landing rule within the available Run will and all the available and in the stands with the established approach by the can avoid a loss of control of the aircraft during approach which is more critical if there is any Terrain surrounding the Runway and finally a smooth flat maneuver can be initiated by the Pilot approach is stabilized.

what is meant by a stabilized approach?

during different ways which come just before the flood and the landing room if the Agra satisfies a set of conditions that your project is called as a specialized approach a few of these conditions are approved speed heat of the 10th landing configuration and aircraft attitude and engine trusting let's look at this condition in more detail

the approach speed during the approach face the aircraft must be of you not faster than desired touch on speed depending on the aircraft manufacturer of this may be defined as we approach or f speed will be at least 1.3 times more than the stall speed of the aircraft for a given landing configuration the rate of different this is regarding the approach angle and the rate at which the aircraft is descending usually the approach angle would be three degrees and the rate of this and would be between 600 to 700 feet per minute the maximum rate of the send for established approach will never exceed 1054 minut in all cases landing configuration the act should be fully configured for landing which is with respect to the flaps and the landing gear in normal flying conditions for a stabilized approach the flaps to be extended family and the landing gear should also be extended it should also be ensured that they are not in their respective positions the aircraft attitude the egg craft must be stable on all the three Axes and only minor corrections may be allowed if required due to external factors during the approach base the potential energy of a graph get converted into kinetic energy so proper Energy Management is essential for the smooth and safe landing the eggrat attitude plays a major role in the total energy management for Ireland is used for your product should have captured and aligned with the localizer and glideslope signal of the Runway in which the aircraft has to land the wireless assist the aircraft in being supplied on the final Descent path

aircraft is descending the engine can be reduced but the engine should be stable and it was provided by the engine will be a little above I will be idle Indian forced applies to produce these conditions should be satisfied depending on whether the aircraft is grown under instrument conditions IMC or visual met conditions VMC there is an altitude limitation by which the aircraft should be stabilized and I am see the aircraft should be stabilized by thousand feet and under VMC the aircraft should be supplied by 500 feet IMC and VMC are defined based on visibility distance from my cloud and ceiling During these conditions are not satisfied it is always best to perform a go around and make a new attempt for landing aircraft they may be many reasons why the approach becomes hand on supplied approach let's take a look at a few of the reasons some of the reasons for an unfertilized approach for visibility adverse weather conditions through fatigue failure of my receiver on both the aircraft any ATC restrictions tureen t enough to go near the airport

Comparison of Subsonic & Supersonic Aircraft| Shock Waves| Designing Commercial Supersonic Aircraft!

Hello and Welcome we will complain subsonic and Supersonic aircraft look at what is meant by shock waves and understand how is Supersonic aircraft are designed first let's look at what is meant by a substance and Supersonic aircraft and aircraft may be defined as subsonic and Supersonic that comparing its speed with the speed of sound if the aircraft flies slower than the speed of sound then it is called subsonic If the aircraft flies faster than the speed of sound then it is called Supersonic aircraft to understand this better we need to do something called as the Mac number

so what is meant by Mach number a Mach number is defined as the ratio of speed of aircraft to the speed of sound for subsonic and craft the Mach number is less than one sensor fly slower than the speed of sound for Supersonic aircraft the Mach number is greater than one can fly faster than the speed of sound usually commercial aircraft can operate at point 62.8 Mach and Supersonic aircraft which are being planned to operate commercially will operate between 1.2 to 2 Mac now let's look at some of the features on or something and craft in a some are usually used for treating the required depending on the size and weight of aircraft in subsonic Aircraft a smooth camber that is used for the wing structure this is to provide sufficient camber so that another is generated when flying at low speed now let's look at some of the features of a Supersonic aircraft a Supersonic aircraft may have it open auto budget and only because the propellers are not efficient at Supersonic speed the Indian designs need to be modified to get up on the high speed of air entering the engine this is done by increasing the length of the diffuser section of the engine another design change needs to be done at the novel section of the engine here the converted divergent nozzle has to be designed so that this aircraft can be accelerated Supersonic speed

on Supersonic aircraft is not efficient screen too much Dragon so what then it would need to be used on an sufficient to produce is directly proportional to the velocity at vijaynagram is flying at Supersonic aircraft fly at a very high speed this app was also symmetric and placed at a small angle of incidence in order to improve the 5th generation and increase the efficiency of the wings just like App for the fuselage on a Supersonic aircraft is also designed to be slimmer than subsonic and aircraft this is because when an aircraft fly at Supersonic speed shock waves are formed at the leading edge of the show will have a significant impact on the design of a Supersonic aircraft since it has severe effects on the air flowing across it let's see what are shock waves and the impact it has on an acre pocket friendly conversation that initially forms on the top of the wing when an aircraft enters the transonic range from Mac point 8 to 1.2 accelerated to Supersonic speed the shock wave is formed at the leading edge of the aircraft because of the shock wave that is found there is a severe increase in the temperature of the Year dance tip of the shock wave source from the materials are needed at the leading edge to withstand the high temperatures there is also a severe increase in the back because of the shock wave formation so the engines need to produce more thrust to overcome this track and hence more fuel is consumed there is also a decrease in the total pressure of the year because of the shockwave this will reduce the engine efficiency the shock waves will also result in a sonic boom on the ground which would be very love and can even cause damage

10+ Incredible Facts About The HAL TEJAS Fighter Jet

 Hello, and Welcome In one of the recent blog we looked at the HAL Tejas and compared it to the of-17 and tried to see some of the differences about this aircraft while finding some similarities between the two but today I'm just gonna dedicate this whole video to India's made HAL Tejas fighter and Discover a little bit more about the aircraft and find out what is unique about it. 

How's it going, everybody? We're a look at people cultures and places from all around the world now today pretty excited Because yeah, I like the hell tears I think it's really interesting that India has its own unique fighter that kind of makes it very special For the people who might be watching this video that are from India but more specifically I like to do stuff that a lot of you guys recommend so You know going into this spider seems to be something that I know you guys will really like With that, by the way, before I get into this video if you guys are into military playlists just to let you know Although we have a diverse amount of content here on MTV facts If you want to know more specifically about Indian military topics I got some playlists throughout this video that I'll put in the cards in the description box below that you guys can check out at Any time, but I'll talk a little bit more about that because I kind of want to get into the facts But I just want to let you guys know the kind of stuff that we do here in case you felt like hitting that subscribe Button at any time in this blog. So let's just jump right into it So we got the Hal Tejas it is classified as a single-seat single-engine Multi-role fighter and for the facts, you might be wondering why is it sometimes called the LC a well? 

There's a reason for that this is because this fighter was developed under what was known as the light combat aircraft program which was a development program Conducted by India for a long time and I'm going to get into that however as for the name to jazz it didn't get this name until about 2003 now one thing that is super important when it comes to the Hal Tejas is it is classified as a Supersonic fighter and not only that but it is the second Supersonic fighter that was developed by an Indian company and this company is known as the famous Hindustan aeronautics company also not only that it's also the smallest and a lightest supersonic aircraft of any of its type in the entire world And yes When I say small it is a rather small aircraft because for the size of this aircraft It comes in at a height of four point four zero meters with a length of thirteen point two zero meters and a width or wingspan of eight point two zero Which makes it just a little bit smaller than some other craft of its type now Let's take a look at why this aircraft was built in the first place pretty much back in the day India knew that it needed to develop a new fighter that would replace its ever aging mig-21 because by the 1980s they eventually knew that the mig-21s would be completely outdated despite the amount of upgrades that they would receive and in the 1980s this was realistically the beginning of the light combat aircraft program specifically actually in 1989 when the LCA program review committee was formed and for the development of its own unique aircraft by 1993 the first proof of concept for the spider was brought in as a matter of fact the first two proof-of-concept Aircrafts that were made were known as TD 1 and TD 2 and for TD 1 it had its first flight on January 4th 2001 in which shortly after prototypes emerged from that and the cost of this first real phase up program came to approximately 2188 crore. 

 10+ Amazing Facts About The F-35 Aircraft

So one thing when it came to the light combat aircraft Programme India tried to develop a lot of different things on their own instead of used technology from other countries One thing that was definitely heavily in production was India's very own fly-by-wire program which began development in 1992 also for what? We now know as the Hal Tejas it was originally intended to have an Indian made radar system and although that might have been developed there was, unfortunately, some Compatibility issues so they had to move on to something else with that Hindustan aeronautics company went with the Israeli radar known as the Alta systems using the specific radar system known as the LM 2032 however in 2008 that's actually changed especially In the mark 1a version because these new health ashes they use what is known as the LM 2052 version, however, It is still an Israeli-made radar but to jump back a little bit after several tests in 2005 the Indian air force put an order for 20 of these fighters Now this actually didn't really mean it was actually cleared for the air force A lot of testing happened after this, as a matter of fact, the first real maiden flight of this first limited series production known as LSP one took place in Hansa Goa on April 25th, 2007 in which the aircraft reached a speed of Mach 1.1. And it was shortly after that that the Indian Navy had intended to purchase 50 of these aircraft however the first prototype known as n p1 was given to them in July of 2010 and it was actually about a year after that the IAF the Indian Air Force pretty much kind of approved the design of this fighter This is because on January 10th of 2011 It was approved for initial operation clearance by the air force shortly after that the naval version made its first flight on April 27, 2012, Unfortunately, the naval version wasn't accepted I'm going to get into that because I'm going to talk a little bit about variants a little bit further on Because it was around this time. 

That although the Indian Air Force had given initial operation clearance This didn't mean it had final operation clearance And that's what you really want as a fighter as a matter of fact the major campaign for final operation clearance began in 2013 but I found it very interesting. And yes also unfortunate that because of several setbacks Final operation clearance wasn't given - the hell - yes until recently, as a matter of fact, February 20th, 2019 Insane that's a lot of years man I mean that fighter is just going through the wringer and the part that I found really fascinating about this is although it wasn't given final operation clearance until recent the IAF had all a lot of interest in this fighter as a matter of fact in 2015 they purchased 120 of them and as a matter of fact in 2011, they had their first squadron formed This was known as the Flying Daggers or number 45 squad Which operated out of the yellow Hakka air base in Bangalore? I should also update you guys and let you know that this squadron has now moved to the seller air force station in Coin Betar, as a matter of fact as of February 1st 2019 this squadron has 14 of these aircrafts but by the end of the year its planned to have another two of the Initially cleared fighters and they also plan to add Sixteen of the finally cleared aircraft to join by the end of the year also It's a rather new aircraft to the rest of the world because it was internationally debuted in 2016 and this was at the Bahrain International Air Show so now let's just take a quick peek at versions and some of the specifications now in my previous Blog I did talk about that So I'm gonna kind of go through this one really quick because for some of you guys have already seen this kind of information I don't want to be repeating a lot of facts So first of all, you have your initial version on top of that there's a trainer version which is a two seater You've also got the Navy versions which I did state in 2016 it unfortunately failed to meet the requirements in weight basically, they found that this aircraft was too heavy for the aircraft carriers and in 2017 they're gonna get a new test to see if they will work the more recent version the mk1 a is unfortunately more expensive However, it has new radar and a bunch of other upgrades the mk2 has been recently displayed in 2019 it is slightly bigger with a larger payload and has a more powerful engine and speaking about engine let's take a look at speed the fastest that this thing has clocked comes in at mach 1.8 with a range of 850 kilometers and a combat radius of 500 kilometers and with that when we look at the engines one interesting fact Is that the original aircrafts use the american-made general electric f404? Engine. However, remember how I said the LCA was aiming to make, you know, Indian-made products for these planes Well one thing that came out of that was also an engine Unfortunately, it wasn't the best. 

This was known as the Kaveri engine and unfortunately It didn't meet the requirements but on a side note which some of you guys you know Your plant enthusiasts might find this very interesting The actual engine itself couldn't be tested in India and actually had to go to Russia The reason for this is because India unfortunately didn't have the facilities built in to test its high altitude abilities and apparently with that Russia used the Tu-16 aircraft to conduct this test and of course when it comes to specifications We got to talk about weapons now currently this aircraft can use nine different types of weapons Basically, you have the 23 millimeter gun in the front and of course you have eight hard points which are located under the wings And the fuselage and can either be bombs missiles or whatever you feel as for the entire program cost Including its research phase one and phase two It came in at seven thousand nine hundred and sixty five point five six crore and for an individual fighter Let's look at the mark 1 and the mark 1a basically the mark 1 comes in at 162 crore which is approximately 23 million dollars And of course I'm talking us but here let's take a look at the mark 1a it really jumps in price because the mark 1a jumps way up to 463 crore or approximately 64 million US dollars Which basically that's about the cost of a Saab Gripen, but either way guysI want to thank you guys for tuning in and learning about the HAL Tejas I hope you guys like this Blog And again, if you really like this one, you want more, you know military content Be sure to hit that like button because hey, that's how I know you guys are interested.

Let me know your thoughts down there Oh, yeah, by the way, I also forgot to mention that as a matter of fact when it comes to the health issues one interesting thing over 70% of this aircraft is made in India Forgot that fact, it's pretty cool you but thanks for watching guys I'll see you guys in the next one and don't forget to check out our other videos Up there down there and at the end of this Blog cool. 

10+ Amazing Facts About The F-35 Aircraft

Hello and Welcome Today we're gonna talk about the f-35 probably one of the greatest fighters to have ever existed in the history of mankind One that some people are going it costs way too much money, but is it worth the price tag? Let's find out How's it going? Everybody? Welcome to FTD facts. My name is Dave Walpole and today Yes, we're talking about the f-35 the fighter that has it all now before I get into this Blog I just won't let you guys know that here on FTD facts 

Well, not just new aircraft I could talk about old aircraft but more or less contemporary ones. So hit that subscribe button Now let's find out more about the f-35. So the f-35 obviously is a very controversial plane Like I said, a lot of people are like you, it's a really expensive aircraft, but it's got stealth That is just amazing truth be told it's stealth is not as good as the b-2 bomber or the f-22 I'm sorry to say this but it's just like a dumbed-down version of those planes as stealth capabilities But it's still amazing as a matter of fact some people already say that the stealth abilities of the f-35 have already been countered by countries like Russia and China Most likely that has happened. It's not been confirmed But even Israel was like yeah in a couple of years this stealth technology is gonna be pretty much useless But however, nothing of that has been confirmed So let's get into some of the actual facts about this aircraft the f-35 was developed by Lockheed Martin and I like to think of it as the little brother to the f-22 the first flight for this aircraft was on December 15th 2005, but for development of this aircraft It's begun as far back as 1992 and so far the program cost of this entire fighter is around 1.5 trillion dollars Sort of don't read I mean you got to read the fine print on why it costs 1.5 trillion dollars because it hasn't really cost that much basically your research development and testing and evaluation came in at 55 point 1 billion dollars and the Procurement of at least 400 of these aircrafts currently, I think they only have about 380 of them out there in the real world however The cost for this came in at 309 Tina point five billion dollars and military construction came to about 4.5 billion So probably a lot of you guys are wondering. Where are that one thousand one hundred and twenty-three billion dollars of that 1.5 trillion? 

Well, that is kind of maintenance for the next a bunch of years I think they say that's like how much it's gonna cost until the Year 2070 that's of course if they plan to have these planes till 2070 like I said if the stealth is already kind of going out they might not now the f-35 is a single-seat kickin But fifth-generation fighter and contrary to what most people believe the f-35 has seen quite a bit of combat Although a lot of this is really recent on May 22nd, 2018 It was said that the first time it was used in combat was by the Israeli air forces in the Middle East Now this was confirmed by the Israeli air chief, However, he didn't state realistically when this happened. So there's no actual evidence to back it up However, we know that the US has used it as far back as September 27th, 2018 And of course, there are other times the u.s. Used it in the Middle East in 2019, and so far its entire fleet has over 90,000 flight hours. So it has been used So one of the biggest controversies is yeah a lot of people say, oh my god, it cost so much on the taxpayers Yes, it did But for all you US citizens out there just to let you guys know it wasn't just on you other Countries from around the world also had to pay the research and development cost for this aircraft So rule number one.

    10+ Incredible Facts About The HAL TEJAS Fighter Jet

Love your neighbors Especially Canada because we definitely helped you guys out with lowering the amount that was going to your taxpayers Basically countries like Canada in the UK and a bunch of others are a part of the f-35 program pretty much This means that these countries had to pay research and development costs because they intended to buy this aircraft Canada right now is actually having a hard time figuring out whether or not it wants to buy the f-35 However, we still have to pay those costs that were part of the initial agreement I mean like we could totally say no, but you know like it's not wise to You know because we're all part of NATO now the one thing about the f-35 is it has a really cool To do VTOL or they call its VTOL basically what it is It's an engine kind of similar to the Harrier jet but this one can actually bend its engine downward and hover It's really cool technology. That is just for the f-35 The one thing is that a lot of people think that there is just one variant out there that is for the f-35 You know, it can hover and it can go straight That's not necessarily the case the f-35 B is capable of actually doing VTOL and going straight But not all versions can do this, For example, the f-35 a I mean it has the ability to just do conventional takeoff The thing with the f-35b is although we can do this. I mean it sacrifices. Uh, it's basically its fuel capacity for armaments and all that sort of jazz For example the f-35 a has an internal 25 millimeter Autocannon where the others need an external one added on top of it at least that's from my understanding Now the f-35 C is also one that has conventional aircraft takeoff But the thing is it's got foldable wings because it's meant for aircraft carriers now the planes so far has three global factories in which it has 1500 suppliers these factories are in Fort Worth Texas can marry Italy and Nagoya Japan And the one thing that's really nice about the f-35 over the f-22 is because the f-35 has a more dumbed-down stealth ability It's a little more friendly for exports and sales now I'm also no expert on these fighters But one thing that is really crazy with the f-35 is it has an insane computer system that is so advanced f-16s are being loaded with a Similar program that is being put into the f-35 However, one of the coolest things of the f-35 is the helmet it has a major upgraded heads-up display Ability inside of it also on top of that the f-35 has six external cameras that are attached to this headset So you basically could just like look around and see everything. 

It's pretty much like you'd be flying in an invisible plane It's pretty much see-through now in today's world. Like I said, there are over 380 of these aircraft made These are operated out of 17 airbases worldwide currently there are about 700 90 pilots that have been trained in this aircraft with about 7,200 people maintaining them on top of that. There are 13 countries that are currently interested or have these aircraft already Unfortunately Turkey is part of that 13, but recently it's well Let's just be perfectly honest the United States because turkeys been buying Russian air defense systems They're like no, we're not sure we're gonna actually sell these aircraft to you. 

Either way guys That is pretty much your basic rundown of the f-35. It's an amazing aircraft. I'm just curious What are your thoughts on the f-35 do you think it's an amazing aircraft? Let me know down there in the comments section below and before you guys get out of here Don't forget to check out our playlist of other great amazing aircraft from around the world I think you guys will really really enjoy it.

10 + Surprising Facts About The F-22 Raptor Fighter Jet

 Hello and Welcome Here on FTD facts, I've been doing a lot of blog around airplanes jets and amazing military Aircraft and nothing is quite as cool and amazing as the awesome Groundbreaking f-22 Raptor a fighter that changed many things about aircraft and how planes are gonna be built in the future One plane that was way ahead of its game But before we get into the amazing facts about the f-22, I should probably introduce myself. Hey, all you lovely people out there How is it going? Hope you're all having a fantastic amazing day My name is Dave Walpole and welcome to FTD facts a channel where I look at well in this particular type of video Military content. 

We also look at countries' cultures and other things like that. So that's kind of your jam You want to hit that subscribe button now a little bit of self-promotion just lets, you know every Thursday I'm always looking at a new plane or an issue revolving around a plane that you might know about for example the next video I'm gonna be looking at the issues with the f-35 and Canada there's quite a lot of controversy around that so that's gonna be coming up next so check out the playlist if you're interested in that sort of thing, so right off the bat, the F-22 is considered a fifth-generation Twin-engine all-weather stealth fighter. Now. What's cool about this fighter is it is one of the times that Lockheed and Boeing? really teamed up to create a revolutionary fighter the f-22 Raptor came from what was known as the advanced fighter program and this began as far back as 1981 I did not know that the f-22 started way back Then this program was aimed to replace the old aging f-15 fighters and be a possible replacement for the rather new F-16 as well. There were new fighters that were on the block such as the sun-27 flanker and the mig-29 Which this program eventually was made to beat those fighters as this program evolved. 

They released what was known as the Lockheed If-22 which had its first flight on September 29 1990 Scientists joined together and competed against this fighter with their particular fighter known as the if-23 Which ironically looks a little bit like an f-35, but the f-35 did not come from that fighter I don't know it just kind of looks different but the thing for the f-22 as it got certified it began production in 1996 Originally America was going to buy 750 of these at the time but as time went on this big deal went less and less and less and less and less because by 2008 because of budget reasons and a few other reasons as well Congress lowered the amount that they could spend on this fighter and only purchased approximately 187 of them however It was shortly before that at the first combat squadron off-22s began conversion in 2005 with that being said one of the first real squadrons of F-22s was the 43rd fighter squadron. 

Now, these guys have been around as far as 1917 as a matter of fact squadron 43 has been commissioned and decommissioned several times in history, for example, they were operated between the years of 1917 to 1919 and then were taken down until 1922 until about nineteen thirty-six and then operated yet again in 1942 1946 and then again in 1964 to 1994 and on a side note during that last time they were the first squadron to do the conversions for the F-15 as well however by 2002 they were brought back into service to provide training for the F-22 which operated out of the Tyndall Air Force Base in Florida. Now, here's the thing. Yes, The f-22 is no longer in production The question is although it is a good fighter of why Isn't it with only a hundred and ninety-five of these ever being made in total? There were a couple of reasons such as they were extremely expensive on top of that There was also the introduction of the cheaper stealth fighter known as the f-35 and even the United States really questioned How valuable the f-22? Was going to be used after the collapse of the Soviet Union and on top of that one thing that really hurt the plane Was the fact that there is an extreme ban on exporting the technology and this plane as a whole to other countries as a matter of fact because the f-35 is Considered a cheaper more dumbed-down version of its stealth abilities That is why the f-35 is allowed to be exported to other countries however That being said the United States doesn't just give out f-35s countries have to have very strict requirements And because of all of these reasons the last f-22 to ever be made was actually in 2012 but although there was a major ban on this particular plane that didn't mean other countries were not interested in it. For example, Australia was very interested in purchasing this fighter Even Japan was heavily considering going into a secure partnership with America to acquire it But the thing was in order to obtain this fighter It would have to increase its military budget to over 1% of the GDP Which is something that has never happened in Japan's history post the Second World War Okay, so let's take a look at some of the more unique facts about the f-22 so for combat, this fighter was first used in Syria in 2014 this was for operation inherit resolved during that operation They say they dropped approximately 270 bombs. However, the f-22 was also used quite heavily for reconnaissance however, that wasn't theoretically the first time the f-22 was in kind of combat because the first time It went in combat. 

Theoretically was up against a bunch of f4 phantoms a very interesting story apparently Iranian forces and fighter pilots attempted to come close to a Predator drone with the f-22 only scaring them off the story is that the f-22 managed to sneak up behind the Iranian f4 phantoms and Managed to come so close that not only the pilot could see what missiles the f4 phantoms were carrying But the f-22 pilot managed to pull up on one of the f-4s wings which made them realize they were dealing with some extreme Technology and therefore backed off and this happened back in 2013 also one of the reasons why Japan was heavily interested in this fighter for long time is Because they were first operated in an international setting out of the Kadena Air Force Base in Japan This was with the 27th squadron and they actually flew over from Hawaii To Japan and on their first flight one of the fighters had to be returned to Hawaii because of severe software problems however This plane did manage to make it back safely to Hawaii get repairs and go forward to Japan and in 2007 This made it the first international deployment of f-22 Raptors and besides that it's also been deployed to Germany Estonia and Poland for training exercises It was also seen in Afghanistan and even Iran in which we already heard from that f4 phantom story But they say in the Middle East the f-22 flew over 200 sorties So here's kind of the downside with the f-22 Raptor being such an advanced amazing piece of technology we get a little thrown off when we hear that the f-22 Actually had some serious problems to begin with keep in mind these were also fixed later on but for example One of the biggest issues with the f-22 Raptor was back in 2013 Where there were many cases of pilots blacking out due to severe breathing problems basically They had hypoxia like symptoms and meaning that they weren't getting enough oxygen to the brain because of this pilots experienced memory loss Emotional liability and a few other things such as a lingering Respiratory problem. This is things like cough and things like that But realistically even though pilots weren't blacked out because they weren't getting enough oxygen This really doesn't help pilots cuz they make bad decisions when they're up in the air lack of oxygen makes bad decisions And with that in 2005, They discovered that the breathing regulator was defective and on top of that the oxygen Generating system reduced the amount of oxygen that was given to the pilots at high G maneuvers Fortunately though the United States military jumped on this as soon as possible and they have since fixed those issues With that because of this oxygen issue. I should also mention that there was one major hull loss Overall, there have only been about four major haul losses of this aircraft, and of that unfortunately two of the four pilots Did not make it now. Let's get away from the dark side. So let's look at some of the specs now 

The good thing is this plane is not over a large one Which is really good for not appearing on the radar and I'm going to get into that stealth aspect in a little bit but let's look at some of the specs first for example its size comes in at a length of Eighteen point nine two meters by a width of thirteen point five-six and a height of five-point zero eight meters Inside this aircraft because it is a twin-engine aircraft. It uses two x Pratt & Whitney f119 pw100 engines and it is Fast now as a matter of fact speed is a very controversial thing when it comes to this plane Speed overall with planes is a rather controversial thing because there's a lot of things to be taken into effect These factors are drag altitude air temperature and things like that that make the f-22 Debated in its speed limit. However, during testing the f-22 showed that it could go up to speeds of Mach 2.25, and in Supercruise meaning it was completely loaded up it got over Mach 1.8. Now the downside is there's been really no official limit of how much this aircraft can carry Although I've read that each wing is capable of carrying up to two thousand two hundred and seventy kilograms Which is roughly around five thousand pounds for its weapons, though It does have one gun in the front and that is a 20-millimeter cannon with about 480 rounds But however for this aircraft, it only has four hardpoints now, of course, They can carry things like bombs and error to air air-to-surface missiles all that jazz and you might be thinking to yourself Yeah, well, there's only four. I mean the f16 can hold a lot more believe it or not It still gets the job done and also cost. This has been a very debated issue as well. However, in 2019 they estimated that the cost per hour for one of these aircraft, while it is flying, comes in at $35,000 again That's per hour but overall one of these babies at least in the year 2000 cost about 150 million dollars with the entire production and development cost coming in at sixty-seven point three billion u.s. Dollars as of 2010 in which I hope the taxpayers are extremely happy with paying that and Last but not least. 

This is probably the greatest factor of the f-22 is the stealth now, here it is I am no expert and anybody out there in the public world is not an expert either This is because the technology around the f-22 is extremely classified heck We know that the f-22 is banned in other countries because it's stealth technology is so advanced But what we do know about the stealth technology is that it has what is known as active electronically scanned array radar which makes the f-22 largely Undetectable on radar screens as well with its unique shape It helps radar bounce off of it, which means that if it shows up on radar It's very very small as the size of a bumblebee. So that's it That's me looking at the great amazing aircraft known as the f-22 Raptor. I absolutely love this aircraft I think it's kind of unfortunate that it's no longer in production. There are talks about a sixth-generation F-22 coming out, but I don't know what's going on with that lot of specs a lot of theories But that is for the future which we cannot predict. Anyways, guys My name is Dave Walpole And I hope you guys enjoyed this video and that being said be sure to check out the playlist up in the cards down in the description box below and At the end of this video because in the next episode, I'm gonna be talking about Canada and its f-35 issue It's really quite a big one and of course just hit that subscribe button if you're new and you want to learn about more cool aircraft because I love talking about aircraft and military gear But that being said feel free to leave a comment and hit that like button if you enjoyed this video and you want more aircraft Blog, but you guys have yourself a fantastic day and I'll see you in the next one.

The Differences Between HAL TEJAS and JF-17 Thunder

Hello and welcome pretty much from Pakistan and India Also, this is part of our military playlist. I'm gonna put them in the cards in this blog also TSo to continue learning about many different amazing aircrafts and everything from militaries from around the world We look at two really unique fighters one Chinese and Pakistan and the other one originating from the country of India and with that we look at the differences between the Jf-17 and the hal tejas and find out if there is a big difference which one is better and perhaps which one is worse Let's go to everybody. 

What's up Dave Walpole here. Welcome back to FTD facts if you are a Reoccuring sort of subscriber if you're new here. Well, welcome to beauty facts for the first time. So today Yes, we are looking at fighters. Now. I love learning about different types of military aircraft from around the world It's just really cool to learn, you know, different specs and kind of what other countries have to offer But the thing is these two fighters for the people from these countries They might be very proud of them because yeah, they original they'll be in the description box below and at the end of the blog if you want to learn more just about militaries Trust me guys. 

We've done a lot of stuff on militaries It's really cool to kind of like put your mind out there. You know what I mean? So now let's take a look at these single-engine single-seat multi-role combat aircrafts both of them are classified as modern fighters as for which Generation they are it's really hard to say because there's nothing really down on paper however for the of-17 Although it is an older fighter many people consider that to be a four-plus generation fighter And as for the Hal Tejas because it's very recent. I could see it as a fifth However, keep in mind just because it's higher up in the numbers. That doesn't make it a better aircraft. That's not true So the of-17 has a really interesting history now its first flight was in August of 2003 however, it wasn't introduced for military function until March 12th of 2007 basically you had this fighter being made by two different companies one from Pakistan and one from China However, there are many different reasons why the two joined together to work on this fighter? First of all, there's a bit of an operational history I mean Pakistan has used Chinese fighters before but however at that time one of the biggest things was that these two-country wanted to produce a fighter that was comparable to the western fighters But was much cheaper to develop in 1989 China was working with a US company to develop what was known as the super 7 which was basically an Upgraded version of the Chengdu f7 Pakistan was also part of this program, which was known as project Sabre, however, unfortunately, The US company had to pull out due to the fact that there were heavy sanctions on Pakistan and there were heavy sanctions on China as well and what I mean by the fact that this fighter has a really interesting history Is these sanctions were put in place because of the famous Tiananmen Square incident? This is where you get this famous photo of the man standing in front of the Chinese Tanks that were brought in to break up the protest Obviously the United States didn't like that at the time so they said not we're not doing this anymore However by 1999 China and Pakistan had joined and signed a contract and that is when work really began Now in today's world, there is really not an actual number of how many of these are flying around They do say that there's over a hundred plus. 

I think it's somewhere around 120 somewhere around there and when it comes to producing this aircraft China has been making them since 2007 and Pakistan has been producing them since 2008 however, as for China interesting fact They do not fly this aircraft They make them and ship him to other countries around the world, as a matter of fact, the first full squadron of Jf-17 s was the number 26 black spiders which became fully formed on February 18th, 2010 with a strength of 14 fighters And by the way, the black spiders is a Pakistan flight squadron and speaking of Pakistan It's said that they operate about 99 of these aircraft currently in the combined history, though Pakistan has a hundred and one of these aircraft. However, a couple of them were lost due to accidents in 2011 There was an accident where the pilot did not survive and in 2016 one crashed in the Arabian Sea and the pilot ejected safely besides that the other countries that operate these aircraft are Nigeria in which they have three of them and the country of my Yanmar which is purchased 16 other countries like Azerbaijani has a deal in the works but other countries like Algeria Argentina Egypt Qatar I ran and many others have an interest in this fighter now jumping over Let's look at the HAL Tejas its first flight was in 2001. However, it wasn't introduced until 2015 but the history of this aircraft, it goes all the way back to 1983 at least it was at this time that India realized that they would need to replace their aging MIG 21s and by 1984 designs decided to go-ahead to build a new fighter for the country Interesting fact when it comes to this fight a lot of people identify it as the Hal Tejas but you could theoretically say it's the ad a Tejas and I'll explain why the reason for this as many people identify this fighter to be developed by the Hindu aeronautics limited and although that might be true most of the Responsibilities was actually under a company known as a DEA which is simply a consortium Company of over a hundred different companies known as the aeronautical Development Agency But to skip all that it was in 1993 that the first phase of this fighter began with a proof of concept and design Development testing similar to the of-17. 

There was also u.s Involvement such as Lockheed Martin was heavily involved in the development of this fighter, However, in 1998 they ended up pulling out simply due to the fact that India Well, did second nuclear tests and the United States really didn't like that, however, with all of that by 2001 they had several prototypes with a developmental cost of approximately seven thousand nine hundred and fifty-six decimal five-six crore testing for this aircraft would go on until 2015 when the IAF ordered 120 of these aircraft and today they are considered the new bad boys of the air and the first full squadron of these for the IAF was the number 45 squadron known as the Flying Daggers and they were formed on July 1st, 2016 now as for operators well pretty much You've only got one Country that's operating this aircraft partially due to the fact that it is brand Spanking new and that is the country of India. And even though they are very careful with this new fighter They have recently stated that they would allow friendly and neighboring countries to purchase this aircraft For example in January of 2019 Malaysia even had an interest in this fighter as for the current number of these Well, it's been said that India has 120 of them on order currently as of 2019 including prototypes There is only 28 of them made and keep in mind when it comes to the 120 I'm not a hundred percent on that because there are some mixed reports in 2016. They said that India also ordered 83 of them So I think it's 120. But again, there's some Miscommunication in media. They're moving right along. Let's take a look at some of the variants of these fighters So besides its prototypes the of-17 has three variants there is the of-17 block one And of course, block two which has improved avionics enhanced load-carrying Electronic warfare abilities and much more. Unfortunately, the original one did not have an air refueling capacity So they blocked two now has corrected that there's also block three which is the most recent which they added a helmet-mounted Display in sight multi-panel and function display upgrades to the radar and infrared and this all came in 2017 on top of that. 

There's also the jf 17 B, which is basically your two-seater version It has enhanced surveillance abilities and is somewhat used for training as for the Heritage as when it comes to its variants There's really only one type of them that is currently in use by militaries however There are other variants that have been built or are at least in future plans besides the MK 1 the MK or mark 1a Has increased radar which is the AES a radar which is developed with Israel It is also a thousand kilograms less and has more maintenance-friendly similar to the jf-17 The first original version did not have the capability to refuel in the air, However, the mark 1a fixes that there's also plans for the mark 1 Navy This one's to address major naval concerns And the biggest one is that is way too heavy For the carriers that they have and it should be able to take off on a small runway They also have plans for a mark 2. 

However, this won't be completed until 2022 it is aimed to have a more powerful engine which will help with increase load and as well There is radar infrared upgrades and onboard oxygen system upgrades as well So now let's take a look at how these stack up in other particular stats So looking at length, you got the jf-17, which is approximately fourteen point nine three meters You've also got the Hal to jazz, which is thirteen point two zero meters for its wingspan The jf-17 is a lot bigger with nine point four eight meters where the two jaws is eight point two zero Meters and for height the jf-17 comes in a little bit bigger at four point seven two meters where the tediz is Four point four zero meters basically the outage s is just a little bit smaller which could be helpful for dog fights or anything like that as for the max takeoff weight the Jf-17 has twenty nine thousand seven hundred and fifty pounds Whereas the hal tejas can have a total of twenty-nine thousand one hundred pounds speed However, the jf-17 can go to mach 1.6 and the two jaws can go to mach 1.8 the service sealing however The jf-17 can go much higher at fifty five thousand five hundred feet. Where the Tisha's Has a ceiling height of fifty two thousand five hundred feet now as for operational range This is including with drop tanks the jf-17 can go Approximately one thousand three hundred fifty two kilometers where the two jaws can go one thousand seven hundred and fifty kilometers For weapons though when it comes to these two fighters, ironically enough They both use the same guns because the jf-17 in the house has used a one x 23 millimeter twin-barrel cannon, which is known as the GS h twenty-three hardpoints though This is also where they defer Basically your jf-17 can carry seven x four underwing to under tip and one under the fuel Solange meaning that they can carry up to seven different types of weapons for example They can use air-to-air air-to-surface an anti-ship As well an array of different types of bombs from unguided to guided in total it can also hold three drop tanks and many counter Measures the Hal Tejas however has eight times hardpoints Six on the wing one on the fuselage and one beneath the portside intake trunk

There are Nimmons include air two air to surface and air to ship missiles and as for bombs they can have laser-guided or unguided bombs and they can also carry drop tanks and last but not least the one thing that we Got a look at is the cost of these two fighters for the of-17 for its bloc one original version It comes in at 25 million USD. However for its block 3, although it's not official and it is apparently planned It is said to cost 32 million USD cultish as its original version is very similar it sits at 23 million USD, and for the mk1 a for all of its upgrades It's said to jump way up to 64 million USD. So there you go guys That's me looking at the differences between these two fighters interesting enough. They are the more modern fighters from these two countries What are your thoughts on them? Which fighter do you think is better to be perfectly honest? I mean, I always say it's always down to the pilot because simply you see old fighters just totally obliterating new ones It's just kind of What happens but I want to know your thoughts and with that before you guys get out of here Don't forget to check out the military playlist if you like learning about different military topics and last but not least. I'm Dave, Walpole Thank you guys for tuning in and I'll see you guys in the next one.

How Do Airlines Clean and Disinfect Their Planes?

Hello and Welcome back. Today is something very different. We're going to do how airlines cleaning their plane and disinfect their plane. These are the protective suits we're going to put on Anthony yeah I'm going to follow you, see how you do this. - Yes, it's an essential part of uh everyone's safety to ensure that the So we need to cover our heads as well. - Uh yes. Crimps around ya nose to stop up the effects of suppurativa, make sure nothing can go within your breathing area. - And also wearing these glasses. - Yeah. Just for the guys uh uhdisinfecting the aircraft, so if there are any splashes, it can't enter into your eyes. Once the team is on board we're ready to go. - Great. - Final piece Sam, we just have the foot protectors. - Foot protectors, yeah. - There ya go. 

Okay, Sam let me just speak to you through some of the products we've got here. Um, Ishan is topping up um the sprayer, which we use basically for the um the soft furnishings the seat covers, um it's far more effective. Uh, this is a smaller but again another compaction. Um in all of these is an uh uh product called Bactroban. Um, which kills the Coronavirus. These are hand filled also with Bactroban. These are used for the hard furnishings, such as side wall panels, galleys uh and they're applied by disposable uh towels here. - Oh to wipe it on the surface. - Correct. - Is see. - Uh it's far more effective than just spraying. - Yeah. - Once we've used all this, all of this equipment, will then go in a biohazard bag, where it's then uh sent for incineration. Uh, you've got skin exposure there so that needs to be completely covered. Thank you. Okay so what and Paul, my supervisor, are doing, we're checking that all of the people here that we provided to my staff is on correctly. Everything's covered, no skin exposure around the hands where they'll be applying disinfection. Uh as you can see the aircraft is already cleaned, so we will now start the disinfecting process, which we'll start from the rear. Uh, how we apply this is top to bottom, back to front. So we will proceed to the uh rear galley. 

Okay, Sam as you can see a member of my team here is cleaning the rear galley. He's using the spray with the disposable um cloth because it's far more effective on hard surfaces. - Quite a hard job. I can imagine how big the whole airplane, imagine wipe off every corner of the plane to make sure it's all disinfected. - And that is why Etihad uses the same teams for disinfecting. Uh, they know exactly what they've got to do, how long it takes, um so these are experienced guys that are doing it. This housing here Sam, this is where the catering put all their carts, so all of your food is stored within here. Once it's emptied of the catering carts, my guys come in here. Start spraying. And they'll spray all over the side panels, on the floor.  Okay, Sam, so what you've seen, you've seen the guys working on both sides of the aircraft They used the uh pump-action spray to spray the Bacoban into the hat rack, um where the passengers store their luggage so that now is disinfected Okay once the guys have completed the disinfection of the uh the hat racks, we now concentrate on focus on the seating area. Um, which consists of a visual display screen and the tray table. This needs to be 100% disinfected and 100% clean and presentable to the Etihad standard for the customer on board. When we clean any area of the cabin, we use um a disposable cloth and Bacoban itself. The reason that we do this in conjunction with the fogging is that agitates anything that might be on a hard surface. Um, so that makes sure that whatever that was on there is 100% disinfectant and gone. Bactroban is both a cleaner and a disinfectant. Um, it's highly effective against all germs, viruses, um, and bacteria. 

It's a great cleaning agent and it's also excellent for disinfecting. We use it in the seating area, we use it in the uh sidewall panels, we use it in the lavatory, we use it in the galleys, the crew rest, the flight deck. - This seat here the covers were taken off. 'cause I can see clearly it's different to the other seats. What's going on here? - Well Sam on arrival my team come and inspect the cabin because it has to meet the guidelines set out by Etihad Airways. Um if they come on board after everyone's disembarked, and they see a seat cover that might be stained, red wine or coffee, uh they remove it. They replace it with a brand new um seat cover that's cleaned and the old one will be sent be laundered. - Is there anything different you would do in cleaning business class? - Uh Sam no the disinfection from the aircraft is the same in business as it is in the economy. Um, the safety of the passengers irrespective of what cabin therein, is exactly the sameThe earlier flights to lots of countries now have been identified as highrisk for Coronavirus. So is there any different cleaning procedure you perform because those are high-risk countries? - Uh yes indeed yeah. Any aircraft coming from a high-risk area, such as China, or if there's a reported suspected case onboard, we enhance the cleaning from any other clean which includes uh disinfection respective of the schedule. The time is given to me to make this aircraft safe and clean for the next guests. 

Sam let's go to the cargo hold we need to disinfect, that's where the guest's baggage is stored. The cargo holds are just as important as the cabin, um because there's an area for possible infection. So what we do once um the aircraft has been emptied, we go into there we use the fogging machine and also the handhelds and we clean and disinfect the whole of the um cargo holds. Now that's on a wide-bodied and also on a narrow body. The reason we do this is that the passengers' baggage is held within their areas, so we need to ensure that there's no contamination. Let's talk about the air supply, so modern jet airlines all have a very high airflow rate, so there are 20 or 30 air changes per hour, compared to let's say two or three in a typical air-conditioned building. About 50% fresh air from outside and the other 50% goes through uh HEPA filters, high efficiency particularly air filters. Of the same sort that we use in operating theatres and able to exclude 99.97% or better of viruses or bacteria. 

They usually do much better than that in fact. So the air supply is very clean. - Well after 90 minutes of deep cleaning and disinfecting the plane, now the planes ready for the next departure. As you can see behind, they are doing the final touches and dressing up the plane. Well, thank you so much, Anthony, for showing me the process. That lots of hard work has been put behind making sure the flights the plane is safe and healthy. Thank you so much. - It's our pleasure sir.
