The test flight of the J-7 is definitely not smooth sailing, in the test flight, just like the J-8, there are all kinds of problems, but on the whole, it is better than the J-8, that is, its engine is safe and reliable, so far, there has not been a dangerous situation caused by engine failure, but other aspects of the failure, there will also be great danger, the biggest of which is the failure of the control system.

At the beginning, the problem of the rudder surface was a great threat to the safety of navigation, after all, the rudder surface directly controlled the direction of the aircraft, and if it lost control, it almost lost hope, and Qin Feng was able to fly back under this condition at that time, in addition to technology, there was luck.

Now, hearing the voice of his comrade-in-arms, Qin Feng immediately knew that it was another dangerous situation.

I just flew off the rudder, and the other rudder surfaces are intact and can still be operated, and the failure of the hydraulic system will cause all the rudder surface operations to fail!

"001 asks to fly with you." Qin Feng shouted over the radio.

When a comrade-in-arms encounters danger in the air, having a fighter plane to accompany him can play a very comforting role, and Qin Feng now just wants his comrades to remain stable and come back safely.

After all, according to the flight arrangement, it should be you who is on the plane that has failed.

"001, you don't have enough fuel." There was a voice on the radio, different test flights, the airspace was different, one of them was in the east, the other was in the west, and the fuel stored in Qin Feng's fighter plane was only enough to return home.

"001 requests refueling in the air." Qin Feng continued, who would have thought that the test of wet docking had just been completed, and now it was about to be applied.

Refueling in the air!

At the beginning, it was just a successful docking and a small amount of fuel, but now, it is necessary to fill up all your fuel tanks.

After a short discussion, the ground replied: "Yes, pay attention to safety." ”

The refueling pipe of the air tanker had already been retracted, but now, it began to be released slowly, Qin Feng pushed the operating lever and slowly approached the tanker, he was also grateful to the ground, this temporary operation will consume two or three tons of fuel more, which is all money.

However, compared to these, the safety of comrades-in-arms is more important!

The refueling pipe was inserted steadily, and after mastering the operation know-how, it could be successfully docked at one time, Qin Feng didn't feel how proud he was, his heart was already all by his comrades' side.

"085 reports, is returning home, speed 800, altitude 10,000, the plane can still be controlled, the rudder surface is slow to respond."

The constant sound from the radio made Qin Feng's heart a little impatient, but he knew that he had to be stable, steady!

The fuel flowed through the air refueling pipe to Qin Feng's fighter, the fighter began to get heavier and heavier, heavier and heavier, and the refueling pipe was slowly straightened, Qin Feng slowly pushed the throttle stick softly, slightly increasing the thrust, so that the thrust of the engine continued to offset the increased gravity, so that he could continue to maintain level flight, and finally, the minute that was difficult to wait for was over, his fighter, the fuel gauge had been indicated to the far right.

Qin Feng released the throttle stick, detached from the tanker, and then, changed the course, aimed at the direction of his comrades' return, and turned on the afterburner.

The two turbojet 13 engines in the tail burst out with surging thrust, and the fighter continued to accelerate and accelerate, in this kind of airspace, there was no sonic boom cloud, Qin Feng could only feel the slight shaking of the fighter after entering the supersonic speed.

The noise is getting louder and louder, even if the sound insulation effect of his helmet is already quite good, Qin Feng can still feel that his eardrums are a little uncomfortable.

Qin Feng looked out, and he could see with the naked eye that the air refueling pipe at this time was shaking back and forth at a high frequency, and it was precisely because of its shaking that this strange noise appeared.

That's the bad thing about a fixed air refueling tube, it increases air resistance!

In the past, the plane had not yet flown supersonic speed, which was originally a subject for future test flights, and the first difficulty to overcome was to be able to refuel, and when it could be refueled, then other problems would be solved.

Qin Feng glanced at the Mach watch, it was now Mach 1.4, he already felt that his eardrums were tormented by this strong noise and could not bear it, and at this time, the air refueling pipe outside was also shaking so badly, for a long time, it would definitely cause metal fatigue and breakage.

Therefore, Qin Feng stopped accelerating, he turned off the afterburner, and the speed of the fighter slowed down.

After only a short period of acceleration, his fuel was being consumed at an alarming rate, but now, he was very close to the airspace of his comrades.

Qin Feng captured the airspace in front of him with his naked eye, and soon, he found the target that was shining in the sun, it was the cockpit canopy of the Jianh-7, and he found it!

At this time, the height of the J H 7 was less than five thousand, and it was staggering towards the direction of the base, Qin Feng pushed the operating lever and began to turn to the right, after this turn, he was able to follow the side of the J H 7.

Don't be nervous, I'm coming!

Just as he was turning, Qin Feng heard a tremor from the tail, and suddenly, he knew that the engine was surging!

The engine snorted a few times, then stopped moving, Qin Feng glanced at it from the corner of his eye, the engine on the right side stopped, and the engine on the left side was okay, it remained in normal working condition.

During the test flight of the J-8, engine parking was simply commonplace, and often the two stopped together, Qin Feng had already prepared for these, he didn't even report to the ground, because he wanted to set aside the precious radio communication channel for his comrades.

He expertly flipped the switches and restarted his engine, and just as before, a few puffs of black smoke came out of the tail and the engine restarted.

Although there were many failures during the test flight, it was a test flight after all, and after the Jian-8 finalized equipment troops, it was already very stable, and there were very few failures of this kind of engine stopping, it seems that it had something to do with this air refueling pipe.

I'll talk about this accident later.

Now, the most important thing is to bring your comrades back safely.

Generally speaking, when encountering a lost plane, it will be accompanied by the flight and brought back, but during the test flight, when the fighter encounters an unexpected failure, there is an accompanying aircraft, which can reduce a lot of psychological pressure for the pilot, and at the same time, you can also observe the outside situation.

After Qin Feng got closer, he began to observe this Jianh-7.
