The deceleration device of the fighter, what kind of deceleration device is used in the F22 fighter

In normal flight, it mainly relies on the speed brake on the fuselage, which is used to increase the windward area by supporting the speed brake, and the gas flow on the surface of the fuselage is broken to achieve the purpose of deceleration.

In air combat, it is also possible to increase the elevation angle to increase the windward area and decelerate suddenly.

It can also be decelerated with the same effect as the airbrake through the joint action of the flaps, ailerons, and tail under the joint action of the flight control system.

The ground coasting mainly relies on the brakes of the main wheels and the speed brakes.

Deceleration can also be achieved by reducing engine thrust when decelerating.

The F-22 is an Air Force fighter with no tail hook on the fuselage, so it can no longer land on an aircraft carrier like a Navy fighter and slow down by hooking the tail hook.

However, the Air Force has the same blocking net as on the Navy's aircraft carriers (like an open net, but the latitude and longitude are sparse and the warp is thicker), and if the plane cannot land or slow down normally, the plane can be stopped through the blocking net.

Generally, airplanes come with parachutes that are used to slow down. The F-22 does not seem to have one.

The Su-35 has a speed brake, and the F-14 has a speed brake between the two engines in the tail, and the speed brake between the F-14 engines can be clearly seen in the figure below.

Not all fighters have it.

The Su-35 and Su-35 are currently fighters that do not have a speed brake and neither does the F14.

They change the flaps to stabilize the plane and slow down, and although the slowdown, they can slow down the engine first.

The Sea Harrier and the F35 don't either, but they can take off and land vertically, which makes it easier to design the runway.

I don't think I've heard of it, but it's usually slowed down by changing the flaps to increase the air boost.

Use a speed brake when flying in the air.

Airbrake. It is usually used in high-speed aircraft to increase the drag of the aircraft without changing the magnitude of the lift. The airspoiler and spoiler are sometimes the same device, for example, on most large passenger aircraft, the spoiler and the airspoiler are combined into one, and at the same time play the role of reducing the lift force and reducing the speed of the aircraft.

When the aircraft is grounded, the spoiler (speed brake) generates aerodynamic drag to help the aircraft slow down, and also generates downward force to assist the aircraft braking, and enables the aircraft to be firmly attached to the ground. Conventional wheeled brakes are often ineffective at high speeds, as brakes tend to fail due to overheating at high speeds. Therefore, the landing brake uses speed brake and spoiler in the early stage to increase the drag of the aircraft, thereby reducing the speed of the aircraft to the range where the conventional brake can work normally.

Engine thrust reversers are also often used on large jets to help decelerate, while propeller aircraft may use propeller reversers to obtain reverse thrust to help decelerate.

No. Deceleration utilizes engine and friction.

There are speed brakes on the wings, which can be moved, and when they straighten up to increase the windward area, they will slow down. Parachutes are used for short-distance parking, and arresting cables are used for aircraft carrier docking.

It's like if you're standing in a strong wind with a big cardboard, and when you're going with the wind, there's no resistance, but when you're facing the wind, there's a lot of resistance.

It should be slowed down by two tail fins and two wings open, and the F22 is not a carrier-based aircraft, so there is no need to slow down too much, and it should also be parachuteed.

The parachute has high reliability, simple structure, easy to use, and light weight, and has always been the preferred landing deceleration equipment for land-based fighters, and most of the European and American fighters have adopted it!

The only fighter I know of that did not use a parachute was the European Tornado, which installed two spoilers at the engine nozzle position, and formed a thrust reverser by guiding the tail nozzle exhaust forward to achieve the purpose of deceleration, similar to the thrust reverser device of large aircraft, but this device has a complex structure, requires the installation of many additional hydraulic mechanisms, increases the weight, and is not adopted by most countries!

The speed brake on the first floor is used for deceleration in the air at high speed, the speed is low when landing, the damping of the speed brake is small, and the effect is not obvious! As for the maintenance of the umbrella, it is not as complicated as imagined, there is a special umbrella machine, two people can complete it, and the work of the parachute crew is much simpler than the work of the maintenance staff!

Yes, land-based fixed-wing aircraft are basically available, but if the airport is big enough, they are not used. Carrier-based aircraft have tail hooks to land on the blocking cable, and there is no need for a parachute.

The deceleration parachute is actually inconvenient to use, and it is very time-consuming to sort it out after each use, and it is more troublesome to detect and maintain, and it is too wasteful to throw it away. Therefore, many fighter jets are designed with devices such as speed brakes instead of parachutes. Of course, if you don't have too much trouble, you can still continue to use the parachute.

Generally, land-based fixed-wing aircraft are equipped with parachutes, but as long as the airport is large enough, they are generally not used, and the navy's carrier-based aircraft need to use blocking locks, and parachutes are useless, so they are not equipped.

The deceleration ability of the aircraft is relatively strong.

Delta-wing aircraft are generally equipped with parachutes.

The parachute is very simple First of all, it is cheap, you can back up more After landing, take it back to the warehouse and replace it with a bag on the plane Logistics is not only one person Brakes are a good way But to change brake pads and other things are indeed not as good as parachutes.

The airbrake is something that every airplane has, because it's not obvious to reduce the speed by the engine alone, and it takes time to reduce the thrust when the speed is too fast when you refuel in the air, but it's much easier to have a speedbrake.

In fact, the plane has already completed the deceleration action in the air. The speed of the aircraft has generally dropped to less than half of its normal cruising speed before it lands. And this is achieved by changing the shape of the wing.

The so-called change of the shape of the wing does not mean that the wing will be deformed, but that at the rear end of the wing, there are flaps sticking out. Change the attitude of the wings.

When the flaps are extended, the drag of the aircraft increases, but the lift also increases, and the power of the engine is reduced, so that the speed of the aircraft can be reduced and the altitude can be maintained. In the later stages of landing, further reduction of engine power allows the aircraft to gradually decrease in altitude.

As soon as the main wheel is grounded, the engine will be decelerated by the reverse spray, and the spoiler on the wing will open to increase air resistance, and the computer will control the wheel to activate the automatic brake.

Reverse spray refers to the landing of the passenger aircraft, after the pilot opens the thrust reverser, the cockpit thrust reverser indicator light is on, and the hydraulic actuator makes the moving sleeve of the thrust reverser fairing move back, with a choke door, exposing the grille section, blocking the channel of the fan airflow to the rear flow and turning to flow out of the grille section, changing the direction of the airflow to produce a reverse thrust.

1. Engine thrust reverser deceleration.

2. Speed brake deceleration.

3. Wheel brake deceleration.

The thrust reverser lock will be released 10ft before grounding.

As soon as the main wheel is grounded, the engine will be decelerated by backspraying.

At the same time, the spoilers on the wings will open to increase air resistance.

At the same time, the computer will control the wheels to start automatic braking (according to the runway conditions), that is, 3 methods: engine backspray, spoiler, brake, and sometimes the captain will continue to increase the flap degree after grounding to slow down.

Usually, the runway is long enough and the airport does not enforce the transit time, thrust reversing alone is enough to stop the plane.

That is true. After the plane lands, the main means of deceleration are the following three:

1. Engine thrust back.

2. Speed brake.

3. Wheel brakes.

But I would like to point out that the deceleration capability provided by the engine thrust reverser is not very obvious. Its main function is to protect the brakes. As a result, we see that the aircraft's thrust reverser system is not included in the list of minimum equipment. This also shows that it is not particularly important.

I think the thing that should catch our attention the most is the airbrake. Many people think that these small wrenches will not do much to slow down. In fact, the opposite is true, the speed brake is crucial for deceleration!

After landing, the airbrake opens, which destroys the lift structure of the wing, so that the weight of the aircraft is pressed on the wheels as much as possible. In this way, the efficiency of wheel braking becomes very high. If the airbrake does not rise after landing, then the wheels have hit the ground.

But a significant part of the weight of the aircraft is still offset by the lift of the wings. This is not good for the braking of the wheels.

Someone has done a professional test, and the deceleration efficiency of the speed brake can vary by more than 60% between rising and not rising.

The plane must put flaps when it lands to increase the drag.

There are a number of other means.

For large aircraft, there are: open the engine, reverse thrust device, wheel brake, put the speed brake, and put the speed brake, for the small aircraft (fighter aircraft), there are: wheel brake, put the speed brake, put the speed brake, put the speed brake, put the parachute, for the carrier-based aircraft and some airports, there are also blocking cables and blocking nets.

When landing, the general fuel tank is almost empty, the total weight is reduced, and it is easy to slow down.

Lower the front and rear edge flaps to increase the bendability and surface area and reduce the wing load.

Reduce the throttle, glide, consume energy by air resistance, reduce altitude.

Further reduction of throttle approach.

The pull rod, the main wheels hit the ground, the front wheels hit the ground, and immediately open the speed brake on the upper surface of the wing to open the engine thrust reverser device to generate a reverse thrust.

Use the wheel brakes.

Straight to the point, this is reusable, and the ground staff also supports paratroopers, which are set up for ** deceleration parachutes!

A parachute, also known as a drag parachute, is an umbrella-like tool used to reduce the speed of an aircraft when landing. It usually consists of a main parachute, a guide parachute, and an umbrella bag, etc., and is installed in the umbrella compartment at the tail of the aircraft. During the landing and taxi, the pilot controls the opening of the umbrella cabin door, guides the parachute to open first, pulls out the parachute, opens the main parachute, and the air resistance can be increased after the parachute is pulled out and opened, and the aircraft is dragged backward to slow down and shorten the running distance.

The fighter landing parachute is equipped with an unification device, which activates the deceleration device when the aircraft is about to stop, throws the parachute behind, and then tows the paratrooper **. Towing paratroopers is a little-known special branch of the Air Force's ground crew.

Buffer parachute, also known as parachute, is generally used when jet planes land, and can be reused, but the umbrella is very expensive.

Certainly not a one-off. After each use, the ground staff should take it away, and then fold the bag and put it back in.

This outdated design has long been replaced by airbrakes, as well as other better ways.

Not disposable.

If it is very urgent, it is also possible to leave the parachute unfitted.

However, the running distance will be longer, and the tires and brake pads will wear out even more.

However, in most cases, it is impossible to be so urgent, because a sortie does not miss a few minutes, and another group of people can reload the parachute while the bomb is hanging, as long as multiple jobs are not wasted at the same time.

Welcome to the 29090057 Phantom Flame Military Forum.

The parachute is not disposable, but only one is loaded on the plane. It can be re-used after landing, and can be used again after re-arrangement.

Emergencies can be dealt with urgently, and can not be installed. When landing, you need to slide, which consumes tires and brakes.

In general, bomb hanging and parachute loading are carried out by unrelated 2 groups that do not interfere with each other. The ground staff has personnel who specialize in collecting and loading umbrellas. And it's not that you use the parachute this time, and you will use this next time, but there are many umbrellas, and the same model can be used.

So instead of waiting for the umbrella you just dropped to be put back in your plane, you can change it.

At the same time, the loading of the umbrella is very fast, and the umbrella is pre-packed and packed in a metal bucket.

Can be reused.
