Chapter 1974: Pilot induced concussion

During the entire flight, the wings hardly changed. In low altitude and low speed conditions, the wings were always deployed, and when landing, the wings were even more deployed.
Chen Rui carefully operated the fighter plane and flew towards the runway. An accurate glide line showed that his control was very precise.
For pilots, taking off and landing is the basic skill, and many veterans will stumble in this aspect.
In F22, the pilot showed ups and downs in the skit, but the result was not done well. After the plane got up, it went down again. The belly wiped the runway and finally stopped, wiped out several tens of meters, and only repaired it. It took six years and millions of dollars. Maintenance costs.
Compared with take-off, landing is more dangerous. Chen Rui now operates the fighter steadily, and the runway in front is getting bigger and bigger.
There are still many things that make Chen Rui dissatisfied. For example, Chen Rui hopes that the cockpit canopy is integral like the F-16. There is no fixed windshield in the front, and there is no barrier in the way.
However, due to various considerations, it is still the current conventional layout, and the bulkhead is also made into a zigzag shape, which is said to be for stealth considerations. Now, it is a bit distracting.
But fortunately, because the front dashboard area has been greatly reduced, the front cockpit field of vision, only the flat display overlaps, unlike the previous J-7, the entire front is almost completely blocked, and nothing looks good. .
Now, this perfect first flight is coming to an end.
The fighter plane is getting closer and closer to the runway, and the figure of the fighter plane also appears to be extraordinarily tall. Chen Rui pulls the control lever and has a slight slope, so that the fuselage can be used as a speed brake to reduce the speed of the plane. , But, at this moment, the nose of the fighter suddenly rose.
No good, vector nozzle! At this moment, Chen Rui reacted. The plane was equipped with a vector nozzle and was quite agile. Although it was only pulled slightly, the nose was quickly raised. Under the effect of the ground, Lift it faster.
As soon as the nose of the machine was raised, Chen Rui hurriedly pushed the operating lever forward, hoping to balance the head-up torque. Chen Rui did this often in the past.
However, when he pushed, he saw that there was all the ground in his field of vision, and the plane was already about to dive. Diving at a distance of more than ten meters from the ground would definitely be a disaster, so Chen Rui only Can pull it up again.
"PIO, it's PIO!" At this time, someone on the ground could see that the test plane was moving drastically, like a rolling wave, sometimes upwards and sometimes downwards. This is a fly-by-wire fighter. In the most dangerous situation, the pilot induces concussion!
In the fly-by-wire control system, this kind of problem often occurs. F-16 and Su-27 have all fallen aircraft for these reasons, and even Su-27 has fallen more than one. It especially likes to appear when landing, as for performance, it is what it is now!
The plane is like a swing that swings rapidly, with larger and larger amplitudes. As long as it swings back and forth several times, it will crash out of control.
Although this is called pilot-induced concussion, it has nothing to do with the pilot. The main reason is that the aircraft's own operating system is too sensitive and feedback problems.
Simply put, it's like a swinging swing. Originally, a force is applied to prevent the swing from swinging, but this force is always half a beat slower. It was originally over and it should be pushed up, but, wait until it Go, just push it over, so it speeds up.
This situation is the most dangerous, especially when it comes to landing.
In the past, Han Guo developed aircraft, but did not encounter this most dangerous situation. The main thing is that no matter what the flight control is, it was exchanged by Qin Guan, and everyone only needs to understand the program codes. , It has been debugged, and the feedback mechanism is also the most appropriate, so it can prevent this from happening.
The fly-by-wire system of the new aircraft currently being tested is also the most mature, but the operation of the power system is added later. Especially this vector nozzle, now, it is too sensitive, not only does not play a role in reducing the shock, but makes the shock more intense.
Now that the plane is so low from the ground, in this case, if the pilot fails to respond in time, the plane will definitely be destroyed.
Even if it’s parachuting, it’s easy to be too late. The negotiations with the bear country are not over yet. Without the introduction of bear country’s most advanced zero-zero ejection seat, one’s own seat is limited. In this case, even if it is If it can be ejected, I am afraid it will fall to death on the runway. It is too dangerous!
For Chen Rui, this was also a critical moment, and it was a life and death test for him.
How to do?
If there is still height, it is enough for him to directly release the lever. After releasing it, the fighter will be leveled automatically, and he will be out of danger, but not now, because he has no height!
He released the control lever. In the best case, he fell flat on the runway. In the worst case, he fell on the runway vertically. If he continues to correct, the aircraft will be even more uncontrollable.
The choice was made only at one-tenth of a second. Chen Rui did not continue to correct, but with a strong left hand, he slammed the throttle stick to the head.
The two engines at the tail roared and burst into hot flames. Then, they began to exert force over the runway, pushing the fighter plane and flying forward quickly. Even in this case, the wings began to swept back slightly. .
There is only one way to save, and that is to go around!
At this critical time, Chen Rui chose the most correct method at once. With his full thrust, the fighter sprinted forward, and the shock that had just subsided finally!
"Pretty!" Lu Lao shouted from below. Just now, he was nervous. He was afraid that the fighter plane would fall on the runway, and he was even more afraid that Chen Rui, the best pilot, would shed blood in the sky. But now, Chen Rui suddenly It was changed, and it was changed in the most violent way. No matter how you shake, I just need to speed up!
The fighter planes roared and flew past their eyes, and the other people also let out a long breath. An accident dissipated in front of them. An excellent test pilot is the most important!
Chen Rui also took a long sigh of relief. This time, at the very close of a fight, he also burst out his full potential. He can't fall, it's a shame!
He pressed the touch screen with his finger and turned off the thrust vectoring function, so that this terrible system stopped working, and it was ready for a regular landing.
