The busy work kicked off in this way, the No. 03 prototype was in full swing assembly, and Qin Feng also began to continue to test the No. 01 prototype.

"Old Zhou, let Tang Gang go up this time." Another pre-flight meeting, Qin Feng suggested to the chief flight test engineer.

"No, you better go on." Zhou Lao said.

"But I've flown five sorties." Qin Feng said.

Every time he took a test flight, Qin Feng wanted to give it to other companions, but in the end, he was the only one to fly, which made him very uneasy, the test flight team of the five of us, I was flying alone, what is this called!

"When the next few come out, everyone has the opportunity, and now, the main thing is to test the envelope of the flight control system, which you are most familiar with." Zhou Lao said: "At the same time, this is also the meaning of the Air Force. ”

No one is at ease, just rest assured that Qin Feng is alone, so all kinds of subjects let Qin Feng fly alone! There was only one prototype anyway.

The test flight is not to be carried out all the time, every time the test flight is carried out, there will be a large number of flight data, after the flight, it is necessary to calculate and summarize all kinds of data, there is no problem, and then organize the next test flight, in the case of only one prototype, one test pilot is indeed enough, if there is only one person, there is no doubt that it must be Qin Feng.

Qin Feng is already in the limelight, everyone trusts him, even if it is a few other test pilots, they have no complaints when they hear that Qin Feng is on the board.

"However, it is easy to breed my pride." Qin Feng said.

As long as one person keeps flying, there will be a kind of thinking of giving up oneself, which is not conducive to personal growth, and after a long time, it will become arrogant.

"That's all for later." Zhou Lao said: "In the future, more people will naturally fly, now, it's better for you to fly!" Moreover, you quickly practiced your skills, ran in with the plane, and there are important tasks! ”

"What task?" Qin Feng asked.

"To the Captain One, perform an air show!"

When he heard this task, Qin Feng no longer had any opinions, now, even if the first flight of the Jian-10 was successful, there are still voices of doubt, and in China, the No. 1 leader has the power to make the final decision, so it is very important to give the No. 1 leader a flight show and obtain the approval of the No. 1 leader.

After all, this aircraft is still a prototype, and it can fly not many times, so let Qin Feng fly alone, you can better run in, the No. 1 leader has seen the Su-27 flight performance many times, and he has not seen the majestic posture of the J-10!

Apart from Qin Feng, who else can bear this responsibility?

"Yes." Qin Feng agreed, and now, in the test flight, he wants to understand the temper of the plane and strive to reach the realm of man-machine integration as soon as possible!

The No. 1 machine, mainly used to carry out aerodynamic test flights, today Qin Feng's test flight subjects, has begun to enter the field of supersound, if in the past, these subjects can only be carried out in the test flight institute, but now, it must be carried out here, because, the No. 1 machine still has a lot of aerodynamic layout shortcomings, the use of supersonic control rate is still not perfect, so we must accumulate more experience on this prototype, and carry out greater modifications on the third and fourth planes in the back, so, supersonic test flight, which has also been unfolded.

Turn on the afterburner, there is a surging power from the tail, Qin Feng looked at the cockpit in front of him, the numbers on it are rising rapidly, if it is faster than the Su-27, because the power reserve is not enough, it will not work, but, compared with other second-generation aircraft, this is a second kill.

The J-10 fighter calmly pierced the sonic boom cloud and entered supersonic speed, and when he flew in, he seemed to hear the sound of a gentle metal structure deformation coming from the fuselage.

It's not good, there's something wrong with the body! When he heard this voice, Qin Feng was immediately frightened, when he was in the Jian-8 test flight, there were too many times such a scene, and now, there must be something wrong with the plane, return!

Calling the ground tower, Qin Feng piloted the fighter and returned to the ground, at this time, he learned that there was a failure in the test flight, and a large number of technicians had come to the ground.

As the speed of the aircraft increases, the air pressure on the surface of the aircraft will also increase, among them, the nose part is subjected to positive pressure, and some areas behind are subjected to negative pressure.

Everyone gathered around the fighter plane and began to search, but, after looking for it, they found nothing.

"Qin Feng, did you hear it wrong?" Zhou Lao said to Qin Feng.

"No way, I heard it very clearly, you know, when you cross the speed of sound, the noise of the engine has a very small impact, otherwise, I probably wouldn't have heard it." Qin Feng is quite sure, there must be a problem, now, it depends on where the problem appears!

Test flight is a very scientific and rigorous work, test flight is to find all kinds of problems of the aircraft, of course, including structural problems, J-8 skin tearing in flight, J-7 rudder flew off, all encountered in the test flight, and in the end, they were all overcome.

However, I didn't find it!

Qin Feng followed in a circle, and then, when his eyes were on the landing gear, he finally found an abnormality.

"The landing gear door, slightly deformed!" Qin Feng shouted.

When on the ground, the landing gear is outside, and after flying into the sky, the landing gear is retracted, different aircraft, the landing gear is recovered in different ways, which also reflects the wisdom of aircraft designers, among them, the design of the landing gear of the MiG-23 is said to be a beautiful talk, the original MiG-23 as the first variable sweep wing fighter, using the upper monoplane design, as a result, the landing gear has no place, the space is very small, Mikoyan for this open to the entire aviation community to consult the solution to the problem, finally, A college student who attended the school, proposed a kneeling landing gear and successfully solved the problem.

The landing gear of J-10 is also the first in China, after several test flights, Qin Feng is quite satisfied with the landing gear, this kind of landing gear can greatly reduce the impact when landing, and even people do not feel that the plane has touched the ground.

After the landing gear is retracted, it cannot leave a hole on the outside, so there must be a skin to block it, and this part of the skin can be moved, which is the hatch of the landing gear.

The landing gear door of J-10 is divided into two halves and unfolds to both sides, which is also a common way for J-7 and J-8, and after flying, the two halves rotate towards the middle, just like two open doors, and they are easily closed.

Now, the half of the hatch on the right side has a slight deformation, about five centimeters.
