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

The nose of the J-7 rubbed against the grass, a large piece of aluminum alloy skin had fallen off, revealing the equipment inside, the front wheel of the J-7 had become an oval, and the landing gear had been broken from the middle, which was the culprit that caused the nose to hit the ground.

Wang Gang's pace slowed down, this step by step, it seemed to be very close, but Wang Gang was unwilling to walk over immediately, he was afraid, afraid that when he saw the cockpit cover, it was full of blood.

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

"Crunch, crunch." At this time, there was the sound of a crowbar crying, and a ground crew was using a crowbar to pry the cockpit canopy.

The cockpit canopy of the fighter must be strictly sealed before take-off to ensure that it is properly locked, otherwise once it is opened in flight, it is quite dangerous, and now, this J-7 cannot open the cockpit canopy by itself due to the huge impact of landing, and the ground crew is working hard.

The pilots inside, leaning in their seats, seemed to have passed out, which made them even more anxious.

"It's open, it's open!" Seeing that the cockpit canopy was pried up with a gap, the rest of the people reached over and lifted it hard, and the cockpit canopy finally opened successfully!

"Qin Feng, Qin Feng, how are you?" Wang Gang pushed aside the few people gathered there and shouted loudly.

"Quick, carry him down." The paramedics were next to the ambulance, and the stretcher had been placed under the cockpit, so as long as the pilot was lifted down, he could be rushed to the hospital for treatment.

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

I wasn't hurt.

When he just came down, he was a little flustered, but his body was very strong, and this bump was nothing, but when the plane stopped, Qin Feng felt that his body was weak everywhere, and he had no strength at all.

He could only wait in his seat, there was no fuel in the plane, and there was no need to worry about the risk of burning.

Wang Gang had already stepped on the wings and climbed up, his hand reaching next to Qin Feng's neck to help Qin Feng take off his flight cap.

The pilots are all flat-headed, which is more convenient, but now, Qin Feng's short hair has become drenched, and the flight cap and the sponge lining at this time can squeeze out the water.

Qin Feng just collapsed.

Then, Wang Gang stretched out his hand again and unzipped Qin Feng's flight jacket, and the inside of the flight jacket was all wet.

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

"No, I'm fine." Qin Feng watched several medical staff come up, carried himself out, and put him on a stretcher, and at the same time, a little nurse had already begun to grab his arm, find blood vessels for himself, and prepare to infuse normal saline.

I don't have a big problem, all parts of the body, are very good, this is in the ambulance, it will definitely be a full range of inspection, a check, it will not be dark and can not come back, I still want to participate together, check the cause of engine failure!

However, the power of the medical staff is greater than that of the flight captain, as long as people don't sign, the pilot doesn't want to continue flying, so Qin Feng was still carried into the ambulance, watching the saline hanging on it, dripping into his body, the car was shaking, he must have to go to the hospital for a checkup.

Qin Feng could only close his eyes helplessly.

"Immediately retrieve all the experimental data, disassemble and inspect the engine!" After watching Qin Feng leave, Tu Lao stood in front of the plane and began the follow-up work.

Qin Feng risked his life to drive the J-7 back, and his own side also needed to seriously analyze and solve the J-7 failure.

The duty of test pilots is this, during the test flight, they risk their lives in order to equip the troops with fighters in the future and reduce the danger of fraternal troops.

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

The J-7 fighter is equipped with a turbojet-7 engine, which is copied from the prototype R-11F engine of the MiG-21, due to technical and environmental problems at the time, this engine produced from Shenyang Liming 410 Factory, the reliability is very poor.

Although the nominal life is 200 hours, there are a large number of failures in actual use. Most engines are returned to the factory for repair before they reach the end of their life. The most dangerous thing is that the compressor and the first-stage working blades have repeatedly broken, and the blades fly out and damage the entire engine, and there have been many first-class accidents.

After that, the turbojet-7 engine was transferred from the Shenyang Liming plant to the Liyang plant on the third line in Guizhou, and the Liyang plant spent six or seven years concentrating on solving the engine failure, so that it could ensure 100 hours of stable work, and successively adopted 26 improvements, and the quality was significantly improved.

Therefore, Tu Lao is still confident in this engine, this test flight, this J-7 fighter, has only flown for 80 hours, it is said that the engine is still in its life, what can it fail?

The dismantling work is proceeding rapidly.

In the design of the J-7, the convenience of battlefield maintenance has never been considered, for example, the fighter engine of later generations can be directly removed from the fighter and replaced in the field, but the J-7, to disassemble the engine, is to disassemble the entire rear fuselage.

Tu Lao watched the technicians get started together, and after more than an hour, the entire rear fuselage was dismantled.

"Hang back into the workshop, let's go to the workshop to study." Tu Lao said.

In the field situation, the disassembly of the engine is inconvenient, watching the entire rear fuselage being hoisted on the old liberation, Tu Lao's eyes, with a perseverance of scientific researchers, must find the reason!

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

In the workshop, the lights are bright, and more than a dozen technicians are disassembling the turbojet-7 engine.

"It's here, the tubing here has burst." Looking at the broken oil pipe, looking at the burnt marks nearby, Tu Lao pushed his glasses.

"Thanks to our test pilots, we flew this plane back, otherwise, it would not be easy for us to find the reason!"

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

"Found the reason? That's great! Just then, a voice came from behind him.

"Qin Feng, you're back so soon? How's the body? Tu Lao turned his head and looked at Qin Feng, who was alive and well.

Qin Feng was in the hospital, and after a physical examination, it was finally determined that there was no problem, but the doctor's advice was to rest for a week, that is to say, during this week, Qin Feng could not take the plane to the sky.

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

"Comrade Qin Feng, why did you come here?" At this moment, a person behind him said: "611 called, please come over, Song Lao is looking for you." ”

Song Lao looking for me? Qin Feng was very strange, he knew that Song Lao was the leader of the 611 Institute, and he actually took the initiative to find a test pilot like himself?

"Okay, I'll go right away." Qin Feng looked at the technicians around the turbojet-7 engine, then looked at Tu Lao, and said, "I'll come back tomorrow." ”

Watching the energetic and energetic Qin Feng turn away, Tu Lao's eyes were full of admiration, it was precisely because of such a test pilot that the new aircraft was finalized and the sky of the republic was propped up!
