When Wang Gang arrived, the J-7 fighter jet had already stopped.

The nose of the J-7 was rubbing against the grass, and a large area of ​​aluminum alloy skin had fallen down, revealing the equipment inside. The front wheel of the J-7 turned into an elliptical, and the landing gear had also been broken from the middle, which was the culprit that caused the nose to land.

Wang Gang's pace slowed down, and it seemed that it was very close, but Wang Gang was unwilling to walk over immediately. He was afraid that when he saw the canopy, there was blood inside.

This is not the first time Wang Gang has experienced such a scene.

"Cruff, crunch." At this time, the sound of a crowbar prying came, and a ground crew member was using a crowbar to pry the canopy cover.

The canopy cover of the fighter jet must be strictly sealed before taking off to ensure normal locking, otherwise it will be quite dangerous once opened during flight. Now, due to the huge impact of landing, the canopy cover cannot be opened by itself, and the ground crew is working hard.

The pilots inside, their bodies tilted on the seat, seemed to have fallen into a coma, which made them even more anxious.

"Open, open!" Seeing that the canopy hood was pried up in a gap, the other people reached out and lifted it hard, and the canopy hood was finally opened successfully!

"Qin Feng, Qin Feng, how are you?" Wang Gang pushed away the few people surrounding him and shouted loudly.

"Quickly, lift him down." The medical staff were next to the ambulance, and the stretcher had been placed under the cockpit. As long as the pilot was lifted down, they could be rushed to the hospital for treatment.

"I'm fine." Qin Feng, on the seat, opened his eyes and tried hard to say to the others.

I was not injured.

When he got off, he was a little nervous, but his body was very strong, and this bump was nothing. However, when the plane stopped, Qin Feng felt his body weak everywhere and he had no strength left.

He could only wait in the seat, there was no fuel in the plane, so he didn't have to worry about the risk of burning.

Wang Gang had already stepped on the wings and climbed up. He reached his hand next to Qin Feng's neck to help Qin Feng take off his flying hat.

The pilots are all flat-headed, which is more convenient. Now, Qin Feng's short hair has become wet. At this time, the flying cap and the sponge lined with the water can be squeezed out.

Qin Feng was just exhausted.

Then, Wang Gang reached out and unzipped the flight jacket for Qin Feng. The inside of the flight jacket was also wet.

Although he had just rested in the seat, Qin Feng's heart was still beating. When he was dealing with the danger in the air, his heartbeat was even higher.

"No, I'm fine." Qin Feng looked at several medical staff coming up, lifted himself out, and carried him onto a stretcher. At the same time, a young nurse had already started to grab his arm, find blood vessels for him, and prepare to give him saline.

I am not seriously injured, and all the parts of my body are very well. Once I get into the ambulance, I will definitely be a comprehensive inspection. After some inspection, I can't come back even if it gets dark. I also want to participate together to check the cause of the engine failure!

However, the power of medical staff is greater than that of the flight captain. As long as the person does not sign, the pilot will not continue flying. Therefore, Qin Feng was still carried into the ambulance and watched the saline water hanging on it and flow into his body drop by drop. The car was shaking, so he must go to the hospital for a check-up.

Qin Feng could only close his eyes helplessly.

"Retrieve all experimental data immediately and disassemble and check the engine!" After watching Qin Feng leave, Mr. Tu stood in front of the plane and started the follow-up work.

Qin Feng risked his life to drive the J-7 back, and his side also needed to carefully analyze the J-7's fault and solve it.

This is the responsibility of the test pilot. During the test flight, they risked their lives to equip the fighter jets in the future to reduce the dangers of the brothers.

Only by finding the problem and solving it can the test pilot be worthy of the efforts of the test pilot.

The J-7 fighter is equipped with a turbojet-7 engine, which is copied according to the R-11F engine of the MiG21 prototype. Due to technical and environmental problems at that time, the engine produced from the Chenyang Liming 410 Factory was very reliable.

Although the nominal life span is 200 hours, there are actually a lot of faults in use. Most engines return to the factory for repairs before their life span. The most dangerous thing is that the compressor and the first-level working blades repeatedly break, and the blades fly out to destroy the entire engine, and first-class accidents occur many times.

Afterwards, the turbojet-7 engine was transferred from the Chenyang Liming Factory to the Liyang Factory on the third line of Guizhou. The Liyang Factory spent six or seven years focusing on solving engine failures, so that it could ensure a stable work of 100 hours. 26 improvements were adopted successively, and the quality was significantly improved.

Therefore, Mr. Tu is still confident about this engine. This test flight, the J-7 fighter jet has only been flying for 80 hours. In theory, the engine is still in its life span, so what fault can it occur?

The dismantling work is underway.

The J-7 design never considered the convenience of battlefield maintenance. For example, later fighter engines can be directly removed from the fighter and replaced in the field. However, if the J-7 wants to disassemble the engine, it has to disassemble the entire rear fuselage.

Mr. Tu watched the technicians get started together. After more than an hour, the entire rear fuselage was removed.

"Go back to the workshop and we go to the workshop to study." Mr. Tu said.

In the wild, it is inconvenient to disassemble the engine. Seeing the entire rear fuselage being hoisted on Lao Jiefang, Tu Lao's eyes were filled with the perseverance of the scientific researchers, and he must find the reason!

Time passed by little by little, and the sun slowly set.

In the workshop, the lights were brightly lit, and more than a dozen technicians were dismantling the Turbojet-7 engine.

"It's here, the oil pipe here exploded." Looking at the broken oil pipe and the burning traces nearby, Mr. Tu pushed his glasses.

"Thanks to our test pilot for flying this plane back, otherwise it would be really not easy for us to find the reason!"

Because Qin Feng risked his life to fly the plane back, they were able to carefully study it. If the plane fell, the fault would not be easy to find, and future flights would still be full of hidden dangers.

"Have you found the reason? It's great!" At this moment, a voice came from behind.

"Qin Feng, are you back so soon? How are you doing?" Old Tu turned his head and looked at Qin Feng who was alive.

Qin Feng underwent a physical examination in the hospital and finally confirmed that there was no problem. However, the doctor's advice was to take a week off, which means that Qin Feng could not put the plane into the sky during this week.

As soon as he came back, Qin Feng ran over to see if he found the cause of the failure?

"Comrade Qin Feng, why did you come here?" At this moment, a person behind him said, "Station 611 is calling, please come over and Mr. Song finds you."

Mr. Song is looking for me? Qin Feng is very surprised. He knows that Mr. Song is the top leader of the 611 Institute and actually takes the initiative to find a test pilot like him?

"Okay, I'll go right away." Qin Feng looked at the technicians around the Turbine-7 engine, looked at Mr. Tu again, and said, "I'll come again tomorrow."
