Old Chen's footsteps slowly stopped.

From this direction, he could already see the two pilots in the cockpit, no one moved, they all leaned on the back of the seat, quietly, it seemed like he had fallen asleep, and in his heart, he was very worried, for fear that the two people above would never wake up again, the tremor in the air just now was so powerful, and when he was on the ground, the impact was so strong, flesh and blood, can he stand it?

Chen Lao didn't dare to go forward, and at this time, the ground crew had already carried the ladder to the side of the cockpit, and the two ground crew members climbed up, and then opened the hatch.

Although I was afraid that the people inside were no longer good, and even afraid of the miserable situation of the people above spitting blood from their mouths, and even blood from their nostrils and eyes, the ground crew still went up, and when the cockpit cover was opened, the people inside raised their heads weakly, but their eyes were still calm.

"It's okay, they're still alive!" The ground crew shouted.

This sentence is absolutely tragic enough, the first slogan issued by the sky is that they are still alive!

Being able to survive from such a situation is definitely worth celebrating, the ground staff's shouting is not unreasonable, now, Qin Feng smiled bitterly, his hands were forceful, and he wanted to get up from his seat, but he found that he had no strength at all, and his whole body was like falling apart, and he couldn't stand up at all!

Even if I did a hundred massages, there was no such effect.

"Come, I'll help you." The ground crew shouted, and at this moment, the ambulance had already arrived, and a doctor below shouted: "Don't move, don't move, let me check first!" ”

If it is an ordinary fighter, it can also go up by jumping the wings, but the J-7 is different, this plane is too tall, and it can only be done on the ground, so that the doctor can go up on the gangway, and then start to check Qin Feng and Yang Lin in the rear cabin on the spot.

Did the body hurt from that violent vibration just now? It may not be much now, but once you move, there may be damage to some internal organs, and if it is internal bleeding, then the chance of rescue is very small.

After a simple examination, the doctor finally breathed a sigh of relief, there was no major problem, specific, and it still needed to be checked.

The other two sides also set up gangways, and with the help of the outside, the two finally came out of the cockpit, Qin Feng had a wry smile on his face, there had never been such a situation, when had he ever been carried out of the cockpit?

After getting down, they got into an ambulance and took the two to the hospital for further examination, and Chen Lao and others also began to check the plane.

In the cockpit, it is already a mess, dense wires, all kinds of instruments, scattered everywhere, it can be said that this kind of aircraft is only one step away from disintegration, and Qin Feng is using a fearless spirit, in this case, he still tried his best to drive the Jian-7 back, it is really not easy, it is his bravery and fearlessness that gave him the opportunity to check the tremor of this plane, what is the problem that caused it!

Generally speaking, even if it is a normal aircraft, when it encounters various air currents in flight, it may cause the aircraft to tremble, but this is sudden, and now, it must be the problem with your own aircraft.

The previous planes were all modified on the basis of Soviet fighters, and this situation has never occurred, and the current J-7 is completely a brand-new fighter developed by its own side, and there are defects in the design, which is a situation with a high probability.

So, how did this come about?

This is not the tremor of the aircraft stalling, the current situation, there is no doubt, it must be caused by the resonance of the airplane's body, or the problem must be solved from the body.

This point, I'm afraid we have to find domestic experts specializing in the study of flutter of mechanical equipment to solve, this problem is not solved, J-7 will not be able to fly to the sky again!

Chen Lao looked at these instruments scattered everywhere, and his face was solemn.

On the whole, this first flight was a success, it went up and flew back, and the plane was able to fly, and these were all right.

The crowd at the airport gradually dispersed, and only the developers of the plane, around the plane, were carefully studying and studying until nightfall.

"Old Chen." At this time, the plane has been dragged into the hangar, it has been past the time to get off work, but no one wants to leave, everyone wants to find the reason, the flight data of the plane has also been exported, and the data on the recorder also shows the seriousness of the flutter, almost dozens of times per second! It's terrible.

"Qin Feng, why are you back?" Chen Lao looked at Qin Feng who appeared behind him, and suddenly felt very strange, and thought about going to the hospital tomorrow to see him, who knows, Qin Feng actually came back by himself?

"After checking it, all the parts on the body are not broken." Qin Feng said very easily: "Our plane has a serious problem at present, and we must find a way to overcome it." ”

Qin Feng has a characteristic, after there is a problem in the test flight, he will also analyze the problem, it is definitely not a simple report, and even Qin Feng will put forward suggestions for improvement.

This is also the reason why everyone wants Qin Feng to fly, and now, when Qin Feng went to the hospital for various examinations, he began to think about it, what is the cause of this?

If this problem is not solved, the test flight will not be possible.

Hearing Qin Feng's words, Chen Lao's face was also very serious, and everyone else had the same expression, who would have thought that the first flight would actually become like this, there was originally a celebration meeting for the first flight in the evening, but now no one has the heart to participate, the commander of the naval aviation, followed them here for a while, and now they have just left, everyone is in a heavy mood.

"Do you have any ideas?" Elder Chen asked.

"I thought about it for a long time, this kind of tremor may occur in two places." Qin Feng said: "It's either the engine or the body. ”

A fighter plane is originally composed of three parts, the body, the engine, and the avionics, and now, the advanced avionics equipment has not been installed, so it can be said that this aircraft is mainly the engine and the airframe, and now Qin Feng is saying this, isn't that talking nonsense?

Old Chen's eyes lit up, and he said to Qin Feng, "Keep talking!" ”
