The strongest pilot ever

Chapter 125 What kind of bird hit
125 what kind of bird hit
This is not the first time Fade Chen has encountered a special situation in the air.

When he was studying at the Third Flight Academy of the Air Force Aeronautical University, he had successfully handled two air situations, so he was quite experienced.

So, after he noticed something strange, he didn't panic.

What's more, he also picked up the master-level engine parking disposal experience before. He is familiar with handling these things. Whether it is a general special situation or a highly dangerous special situation, he has the experience and confidence to handle it perfectly.

It must have been a bird strike!

Fade Chen's first instinct was.

It is now January, and the temperature in this area is already a bit high in January, and the activities of flying birds have also increased.

However, this is an airport after all, so the corresponding bird repelling work has been carried out well, so there are not as many birds as in other places.

Of course, because it is not our military personnel who carry out the bird repelling work, but the local air force ground crew, there may be a little difference in professionalism.

But this can’t be helped. Now is a time of war, and our army’s air force is not strong enough. At this time, we need to send some to the first line of defense, some to the second line of defense, and leave a lot to protect our country’s air and space security. Therefore, there will inevitably be a large number of staff vacancies, especially some ground staff, so the final result is that they have to be replenished locally.

Of course, there is another reason. After all, this is a joint operation. It is understandable that you need your own people for key positions such as pilots and maintenance teams, but it is not justified if you don’t leave one or two positions for others. , otherwise how to reflect the unity.

In addition, this area is full of forests, and there are more birds than other places.

So, Fade Chen's first instinct was that he hit a bird.

Airplane strikes with birds are very dangerous and often result in crashes.

Why can little flying birds cause such great harm to aircraft in flight?

We can draw conclusions from the momentum theorem of physics.

If an airplane is flying at a constant speed of 300 m/s in the air, and a bird with a mass of 10 kg is flying toward each other at a speed of 310 m/s, then the momentum of the bird relative to the aircraft at this time is [-] kg • m/s.

After the aircraft birds collide, these momentums are almost completely converted into the impulse of the small bird to the aircraft, and the collision time is extremely short, about 3 milliseconds, then the impact force acting on the aircraft due to the aircraft bird collision is about 103 thousand Niu, this is no different from the energy of a cannonball.

The contact area of ​​a bird with a mass of one kilogram is about 0.02 square meters when it collides with the aircraft, so the pressure on the impacted position of the aircraft is 5.15 MPa.

Most of the current aircraft materials cannot withstand such a large pressure, which is the direct cause of various bird collision accidents.

If the flying bird happens to appear near the engine, the flying bird is likely to be directly sucked into the engine by the strong suction, and the consequences will be even more terrible. The engine may be severely damaged, and finally stop directly. As a result of the engine stopping, the fighter plane crashes.

So at the first moment when he noticed something strange, Fade Chen's nerves tensed up. He knew that the next ten seconds would be the ten seconds that would determine his life or death.

His J-[-]C has a single engine, once the engine stops, it will be extremely dangerous.

He was about to report by radio, when suddenly, his brows frowned, and a doubt emerged from his heart.

His sixth sense told him that it was not a bird strike!

He looked at the engine tachometer and airspeed indicator, and other data, and soon, he made a judgment.

This is not a bird strike!
Or, at this time, what he hit was not an ordinary bird.

He has also hit birds before, so he is also experienced. What's more, he has gained a lot of experience in dealing with air conditions before, especially the booklet Zhao Feiyu gave him, which gave him a lot of things.

Generally, the reaction of the fighter plane to strike a bird does not seem to be like this.

A few days ago, he studied the repair and maintenance of the aircraft with Niu Dezhuang, the third-term non-commissioned officer of the maintenance brigade. Through studying with Niu Dezhuang, he had a deeper understanding of fighter jets, especially with Niu Dezhuang. He has gained a lot of experience in the operation of the aircraft, and he even learned to judge the operation of the engine based on the sound of the engine and the shaking state of the fighter plane, so at this time, he made a judgment at once.

At this time, the monitors in the cabin were all black, and all parameters could not be known.According to special situation handling rules and flight experience, it can basically be judged that the engine stopped.

Special situation solutions flashed in Fade Chen's mind one by one, and he held the joystick and accelerator firmly.

Accelerate slowly, close slowly, no response;
Accelerate quickly, there is no response;

Turn on the air ignition switch, still no response.

Chen Fei had a judgment in his mind.

Before he could contact the control tower, the voice of the tower sounded: "Ying Long, what's going on, why is your engine sparking?"

Chen Fei replied by radio: "Control tower, I hit a bird, and the engine stopped! I guess, what I hit was not an ordinary bird, but a bird drone!"

Fade Chen's voice was very calm.

But his words made the duty personnel in the control tower almost jump up.

what?
Bird drones?
Chen Fei's engine hit the bird drone?

How could there be bird drones here?
This area is not a residential area, and there will be no cases of people playing drones. Besides, the local level is generally backward and does not meet the conditions.

So where do drones come from?
Whose drone is it?

In everyone's mind, 1 doubts jumped out.

Although the bird drone sounds strange, it is not a novelty in the military. As early as a long time ago, the media publicly reported that I, Northwestern Polytechnical University, independently developed a "robot pigeon" drone. It accurately replicates 90% of the flight movements of real birds, which is highly realistic enough to "fool" real birds and sensitive flocks, and even escape radar monitoring!
If what Fade Chen was talking about was this bird-like drone, then it would be troublesome.

Soon, the tower's voice exploded on the radio: "Ying Long, skydive, skydive!"

"I'll try again to see if I can drive the fighter back!" Fade Chen said.

If you parachute at this time, the fighter plane will fall directly to the ground. There is still a lot of aviation fuel in the fighter plane. Once it falls to the ground, the fighter plane is likely to explode, and the terrain where the fighter plane falls is very complicated, full of jagged rocks. In that case, all the fighter planes would be destroyed, and more importantly, if all the fighter planes were burnt down, it is very likely that the fragments in the engine would not be found, so it would be impossible to determine whether his speculation was correct or not.

Fighter planes are very expensive, but if his speculation is true, it will be more precious than the value of the fighter planes, so Fade Chen wants to give it a try!
At this moment, Fade Chen's fighter plane barely aligned with the runway.

"Control tower, I made a forced landing!" Fade Chen said.

"Okay, we can make a forced landing, the ground is cleared, the speed is acceptable, and the altitude is lowered slowly." The control tower said.

The tower commander also understood what Fade Chen meant, and also understood the value of taking risks, so the commander was under tremendous pressure.

"Open the landing gear!" said the tower.

Chen Fei opened the landing gear.

If the landing gear cannot be put down, it will be troublesome.

Fortunately, the landing gear was lowered normally.

"The landing gear has been lowered, lower the altitude slowly!" said the tower
"Understood!" Fade Chen slowly pressed the lever.

"Height one hundred!"

"50 meters!"

When it was 20 meters above the ground, the tower said: "Open the parachute!"

Fade Chen opened the parachute.

bang——

The parachute opened suddenly, and the fighter plane seemed to be pulled by a big hand. The speed dropped again, and the fuselage also twisted.

The attitude of the fighter plane was originally a bit crooked, but when it was dragged by the drogue parachute, the flying attitude was immediately aligned. The ability of the tower commander is really leveraged!

"Ying Long, pull the lever moderately!"

"Understood." Fade Chen slowly pulled the lever and raised the nose of the aircraft a little.

"Ten meters!"

"Eight meters!"

"Five meters!"

"Land down immediately!"

bang——

The fighter plane landed heavily on the ground, and then ran diagonally forward.

"Brake!" the control tower said.

Fade Chen braked.

The speed of the fighter plane finally slowed down.

The ground staff and maintenance staff had already been waiting for a long time, and once the fighter plane stopped, they immediately rushed forward and began to deal with it.

This time, the special situation in the air was finally dealt with without any risk!

very good!

Fade Chen heaved a sigh of relief.
