In flight, engine shutdown is a serious malfunction, when the engine stops, the aircraft loses power and falls like a large rock to the ground.

If you are an ordinary pilot, you will inevitably be nervous and at a loss when you encounter this situation, and if you can fly back the plane that stopped in the air, you will be able to get a first-class merit.

And now, this is not the first time Qin Feng has experienced it, his psychological quality has been trained very strongly, and before the rudder surface is locked, Qin Feng has already calmly begun to deal with it.

The nose of the aircraft is leveled from the climb state, with a slight slope, so that the plane accelerates, and the air flow hits the engine, and the engine can be revved again.

"006, report the situation." The sound of the ground came from inside the headphones.

"006 reports, twin engine parking, preparing for air start."

The engine of this J-8 fighter is exactly the same as that of J-7, it is all turbojet-7, Qin Feng has long understood the temper of this engine, although it has been parked in the air, it is still not in a hurry, under the impact of the air flow, the engine has begun to spin, the waste oil inside is sprayed out, the combustion chamber is cleaned up, and then, the air ignition!

Qin Feng's hand twisted on the electric door, expecting the familiar roar from behind.

But no, there is nothing behind!

The fighter plane was still falling, and it would probably decrease in height by a hundred meters every second, and Qin Feng knew that there was not much time left for him.

"The air start failed, and a second start was prepared." Qin Feng said.

After the engine is stopped in the air, there is no help from the ground power vehicle, so it must be difficult to start in the air, and various complex conditions must be met.

The first start failed, probably because the height was too high.

Now, my altitude is about 10,000 meters, and the temperature of the outside air is minus 50 degrees Celsius.

Therefore, even in summer, pilots must wear leather flight suits, otherwise they will have to eject at an altitude of 10,000 meters, and they will have to freeze into popsicles.

In this case, the inlet air temperature of the combustion chamber is very low. The fuel injected in the combustion chamber is not atomized well and is difficult to ignite, so the tail engine of the aircraft keeps emitting black smoke, that is, it does not catch fire, just like starting a car engine in winter.

The fighter plane is still falling downward in level flight, about a hundred meters per second, Qin Feng took a deep breath, and then looked at the dashboard in front of him, this time the conditions coincided again, and continued to start in the air!

His hand flicked the air start switch a second time, and then he listened almost with his ears pricked up.

There is no familiar roar!

What's going on?

Qin Feng was very strange, the second start, failed again?

At this moment, Wang Yang's voice came from the radio: "006, the power supply of the J-8 is sufficient, start repeatedly, keep starting repeatedly!" ”

As an early test pilot of the J-8, Wang Yang has long experienced the problem of J-8 air parking, and his solution is to start it repeatedly.

The space of the fighter is precious, a small aircraft like the J-7, two air starts can exhaust all the power, but the J-8 is different, after all, its take-off weight is large, and it is a double engine, so there is enough margin in the design, with sufficient power, it can meet the needs of multiple air starts!

"006 Roger." When Qin Feng heard this, his anxious heart just now calmed down again, and he was actually already anxious after two failed air starts.

And then, for the third time!

With a height of eight thousand, Qin Feng activated for the third time.

This pneumatic operation still did not succeed!

If it was the previous J-7, now the whole plane should be powered off, and the J-8 is still steady, Qin Feng also admired this very much, and followed him to start the fourth time.

The fourth launch, still fails!

The altitude has dropped to six thousand meters.

Next to Qin Feng, a silver-white shadow suddenly flashed, and when he turned his head, he already saw Wang Yang.

Wang Yang piloted the J-8 fighter and had already flown next to him, and today Wang Yang was also conducting test flights in other subjects, and when he heard that Qin Feng was malfunctioning, he immediately flew over.

With his comrades-in-arms by his side, Qin Feng calmed down and took a breath, Lao Tzu didn't believe that you were still good!

"It's coming, it's coming!" Wang Yang, who was flying with him, shouted, he watched two black plumes of smoke coming out of the tail of the J-8 fighter, obviously the engine was restarting, and it was still not completely burning!

He was expecting this puff of black smoke to suddenly disappear and then turn into flames, however, he was disappointed, the column of smoke rose for five seconds, and Qin Feng gave up again.

The altitude has dropped to 3,000 meters!

The last chance, if the restart is unsuccessful, then you can only parachute, the ejection device of this aircraft is extremely unreliable, if you parachute, the possibility of sacrifice is greater.

I just got a first-class merit yesterday, is something going to happen today?

Qin Feng gritted his teeth and twisted the electric door again.

This time, there was still black smoke at the tail, and the black smoke gradually became lighter, and suddenly, the flames came out, and the familiar roar came out!

"Height one thousand five, the sixth reboot is successful!" Wang Yang shouted, "Now it's time to step up the gas pedal." ”

The engine has finally started successfully! Although Qin Feng was still calm and calm in the process, the sweat on his forehead was still coming out.

At a height of one and a half thousand, he finally opened the goggles of his helmet, he gasped twice, or the air outside was fresher, and then, steadily pushed the throttle lever to increase the power of the engine.

"006 requests to return." Qin Feng shouted over the radio.

This kind of aircraft is even more difficult to operate than the J-7!

One of the advantages of twin engines is that if one engine fails, the other can support the plane to fly back.

But what about now? The engine of this J-8 fighter stops together when it is parked, and there is no room for relaxation, and the air start always fails!

Six times, if it were an ordinary pilot who came to fly, and failed to start in the air twice, it would have collapsed, and he would have parachuted.

Why do you have to launch so many times to succeed? What other flaws are there in the design of the aircraft? And why does the engine stop? An ordinary action can also cause parking?

While Qin Feng was piloting the fighter plane back, so many questions began to flash in his mind, this aircraft must have huge design flaws!

Now, let's look for its questions.

Qin Feng drove the J-8 fighter and stopped steadily on the tarmac, and in the back, Wang Yang's fighter also landed.
