Why can t the blocking cable hook the wheels of the aircraft?

The landing deceleration device generally uses four arresting cables, the arresting cables are horizontally placed above the middle of the landing deck, 10 centimeters from the height of the flight deck, and the spacing between the four arresting cables is about 10-12 meters each, before the carrier-based aircraft lands, the landing hook at the tail of the aircraft is put down, and when the aircraft is taxiing at ultra-low altitude above the flight deck, the hook is hung with the arresting cable horizontally placed above the flight deck, and the arresting cable instantly generates a huge tension to drag the aircraft. The end of the blocking cable is connected with the hydraulic system of the reducer, when the tensile force pulls the end of the blocking cable out of the hydraulic system, the hydraulic pressure is in the hydraulic unit, and the hydraulic oil is sprayed out from the thin tube, so that the air in the air cylinder is pressurized, so that the friction force and the air pressure of the flowing hydraulic oil can produce a huge pulling force at the same time, and the gravitational acceleration and thrust when the carrier-based aircraft lands on the ship cancel out the aircraft to stop moving.

The front wheels are cocked, but is the rear wheels also cocked?

The arresting cable cannot be hooked to the rear wheel of the aircraft because the distance between the arresting cable and the deck is less than the radius of the rear wheel, so it is impossible to be hooked.

There is no need to go into a long story: because the fighter plane is at an angle to the deck of the aircraft carrier at the time of landing, and the wheels are at least 2 meters above the deck. Moreover, the arresting hook on the fighter is mounted on the very tail of the aircraft, so it is impossible to hang the wheels.

This requires the skills of carrier-based aircraft pilots to be absolutely excellent! Carrier-based aircraft pilots are ace pilots among ace pilots! He must train the carrier-based aircraft to be integrated with his own body!

Do the integration of man and machine! He had to be able to fly the plane knowing its parts as well as his own body! In this way, there will be no errors in the landing of the ship.

If the plane hooks the nose landing gear while landing, the plane will lose control and crash into the planes and people on the ship island or deck! Cause a major **!

An aircraft carrier that takes off in a glide jump will not affect the landing! Because the plane landing is from the rear of the aircraft carrier, and the aircraft carrier also has a 30-degree oblique deck, which is specially used to land the aircraft!

The carrier-based aircraft also has radar guidance and a landing assistance system. The rows of light boxes on the aircraft carrier are the landing assistance system. The emitted ray lights will alert the pilot.

The landing hook is raised and downward. The rear wheel of the carrier-based aircraft now touches the deck. The barrage with the deck has 15 cm.

The wheels of carrier-based aircraft have a diameter of more than 50 centimeters. Directly over the barrage.

Radar guidance is designed on the aircraft carrier, which is a string of street lights, but instead of emitting light in all directions, it emits a very narrow beam of invisible light like a searchlight, an infrared beam, and the two rows form a beam corridor, which is not easy for the enemy to detect.

The designer has a smooth glider aerodynamic shape in the tail hook of the tail hook of the ship, and a tape measure elastic stretch tail hook cable. Buffer impulse.

The hook behind the paratrooper is the hook for the main parachute, which is generally used when jumping large high-altitude aircraft such as transport planes.

After the carrier-based aircraft is stopped, because the inertia of the hydraulic system of the arresting cable will pull the aircraft back a little, the cable will naturally fall off the landing hook, and then the arresting cable will be retracted by the winch to its initial position.

Behind the paratrooper is the rope is an automatic parachute opening rope, after the paratrooper leaves the warehouse, the parachute opening rope is tied inside the cabin, and the other end is pulled by gravity to open the parachute bag. The earliest skydiving was manual parachuting, you had to pull the rope yourself, now unless stunt skydiving and special purpose skydiving (such as low-altitude parachute rappelling) to get out of the cabin do not open the parachute, the parachutist manually open the parachute, the others have changed the automatic parachute cable.

P.S. If the main parachute fails and does not open, the parachutist still has to manually open the parachute rope to open the spare parachute.

Who said that the blocking cable is being untied to drag the fighter backwards? The upstairs probably doesn't even know how the blocking rope works, right? First of all, the force of the fighter is very large when landing, and the pilot constantly transmits various data of the fighter to the aircraft carrier, such as the number of engine revolutions, how much fuel, how much **, and speed and so on.

In this way, it is possible to calculate how much pull is needed to bring the fighter to a complete stop, and the biggest problem is not to damage the fighter. When the fighter hooks the cable, the two ends of the cable continue to elongate, but there is a certain ratio. If it is stretched too slowly, the fighter may break, and if it is stretched too fast, it will not be able to hook the fighter.

When the fighter plane came to a standstill, the pilot slowly turned off the engine, and the crew continued to extend the arresting cable, at which point the cable slowly fell off the hook, and the fighter remained in place. Finally, the hook is picked up manually.

The paratrooper's hook is to open the parachute bag, so as to save the paratrooper himself in the process of pulling the parachute rope to open the parachute and run.

The hook of the paratrooper is actually connected to the parachute line. After the paratroopers jump, the parachute rope is hooked in the plane, so that the parachute rope is naturally pulled off, and the parachute bag is opened, so the paratroopers jump out of the plane and open the parachute, and there is no need for the paratroopers to pull the parachute rope by themselves.

If you don't use a hook to hook it, then you have to pull the parachute rope yourself, which is a potential safety hazard for the paratroopers to land in the whole batch, because if the paratroopers pull the parachute themselves, if the person who jumps back pulls the parachute later, it may open the parachute in the same air position as the person who jumps in front but pulls the parachute early, causing the parachute bags to be entangled with each other. And with a hook, everyone is opening the parachute at the moment of jumping out of the cabin, and this problem does not exist.

As for the problem of the aircraft carrier, after the aircraft lands and hooks the arresting cable, the blocking cable will be stretched while relying on the hydraulic device to slow down the aircraft, after the aircraft stops, the blocking cable has been stretched very long, as long as the aircraft is dragged a little, the blocking cable will be loosened, and it will be easily removed. Then you can roll the blocking cable back into place.

The person took Guan Gong's big knife and got it done.

There are usually 4-6 barrages on the flight deck. The following picture is a schematic diagram of the aircraft carrier arresting cable, from the stern to the bow of the ship in order of the first, second, third, and fourth lanes (the French "Charles de Gaulle" aircraft carrier is 3 lanes).

Generally speaking, the landing that can hook the second line of blocking cable is a full-score operation, the third line is second, and the fourth line is not a failure, but it can only be regarded as a barely passing operation, and this kind of landing operation is not advocated. And if a pilot hooks the first line of arresting cables, I am afraid that he will be scolded, because hooking the first line of arresting cables to land on the ship means that there is a very big risk hidden in the process of landing this time.

It is aimed at the second one, because the aircraft carrier fluctuates with the sea surface at any time, so when aiming at the second blocking cable, even if there is a deviation, it can be hung on the first one.

Three or four, and if you aim at the first one, you can still hook the back when the landing angle is large, but when you are small, you will fall on the deck, and this angle is related to the state of the aircraft carrier.

The first and fourth ropes are side ropes with auxiliary properties. Under normal circumstances, it is the second and third ropes of the hook.

Hooking the first and fourth ones has some element of luck. It's okay to talk about it in the evening. Especially during the day.

The commander will consider whether you should join the training camp or retire!

It is possible that the hook is not hooked, especially the shape and length will have an impact, and it also looks at the ship's attitude and RP to some extent, like the current F-35C's interception success rate is too low, and it needs to be redesigned to a certain extent.

For example, near page 33 is the tail hook of the F-35 and the shape to be corrected later.

But if it's already hooked, then it's impossible to pull forward to get out.

After entering the landing route, the landing system continues to transfer the flight status of the aircraft, the angle of entry and the place that needs to be adjusted to the pilot, and the tail hook is put down in the last 100 meters under normal times, and before the rear wheel is stained with the deck, the tail hook has passed through the blocking cable area, and hooked up a rigging, but most of them are the third and fourth lane, and the hook is like the structure on the keychain hanger.

If you hook it, you won't get out, and if you can't hook it, you won't be able to fly back and ......land again

Take a look at the shape of the tail hook of the carrier-based aircraft yourself, once hooked, the shape is guaranteed not to accidentally detach.

Under normal circumstances, if the arresting cable is hooked, the aircraft will definitely be able to successfully slow down, and if it can't be hooked, it will go back to flight directly. When a carrier-based aircraft lands on an aircraft carrier, there is a specified speed, which cannot be too fast, but it must not be too slow, and the purpose is to make a go-around flight without being able to hook the blocking cable. The oblique triangular deck, which is necessary for modern aircraft carriers, is also to separate the landing and take-off operations, and to ensure that the unhooked aircraft have enough space and time to return to flight.

The go-around is mainly when it is not hooked, if it is not hooked, the pilot can feel it, and then the afterburner can fly up and come back.

Under normal circumstances, the landing speed of a modern aircraft is 260 kilometers per hour, and if you hook the arresting cable, the aircraft will definitely be able to succeed. For 260 km h, the arrestor can easily reduce the speed of the aircraft to 0 in 2 seconds

There are generally three blocking cables.

There doesn't seem to be a case where the blocking cable has been pulled off or the tail hook has been torn off.

If you can't hook the blockade, you have to refuel and return to flight. Like the one upstairs said, when you land, you can turn on the maximum horsepower, and that is to find death. After landing the ship, he began to refuel suddenly, otherwise the speed of the ship would be several hundred, and hooking the blocking cable would directly tear off the tail of the aircraft or pull the blocking cable, and then the plane would be directly tied to the deck.

What does it mean to be in a bad situation?

If the blocking cable or tail hook is broken (the probability is almost 0 in reality), there is a blocking net in front. The plane will not fall into the sea.

If it is not hooked at all, then it can only be a go-around. The U.S. Navy stipulates that carrier-based aircraft should land at a speed of no less than 200 knots (as if this is the speed).

If you hook it, you can land the ship normally, and if you can't hook it, you need to increase the thrust of the engine and go back to flight.

Shake off?? It's not to get rid of it, it should be that the blocking cable is broken, and the horsepower is at its maximum when the plane lands. Even if the rope hook is blocked, continue to slide for a distance and take off.

General Zhang said no, but now that he has the ability, I can't tell. I don't think I can fly anymore.

Hello: For this issue, I and you ** as follows.

1.The clear answer is that these so-called "curved steel plates" are not used to raise the blocking cable to improve the probability of the tail hook hooking, and there is no problem of the fighter landing to press them, because these things will not exist on the deck when the aircraft carrier takes off and lands.

2.Let me explain, the aircraft carrier blocking cable itself is a certain distance from the deck, and the position of the carrier-based aircraft tail hook itself is lower than the fighter wheel, in other words, whether to break out of the blocking cable area is the key, landing in the effective area of the blocking cable, but the tail hook because of the slippage, none of them hooked, then it should be the designer ...... of the fighter tail hook who pulled out and shot it

3.You can also change the angle to refute this problem, assuming that the blocking cable needs to be raised in height, then it is better to use 4 steel plates to cushion it in the middle? Or is it better to fix the two ends of the blocking cable higher and tighten it?

4.In this picture, the deck is messy, and the personnel are wearing construction helmets, not military helmets, indicating that this is during the construction of the aircraft carrier, when the real carrier-based aircraft take off and land, the deck needs to be very clean and flat, and even the deck personnel need to work hand in hand to check the foreign objects on the deck in a carpet style, how can it be possible to put 4 boards on the ...... in a grand manner

Kindness! These are some of the auxiliary facilities used in deck maintenance, they can be hidden when fighters take off and land, and there are many auxiliary facilities on the deck of aircraft carriers that can be hidden, and they will automatically appear when they are used, such as the barrage net on the deck, the fixed equipment of the aircraft, etc.

This is used for training when landing on the road, that is, without a rope, and then pull the plane up when it falls into this position

This picture was taken when the deck crew was maintaining, and the deck was flat when it was actually used.
