Second-generation aircraft requires pilots to adapt to the aircraft, and what are the taboos of the aircraft must be kept in mind to avoid letting the aircraft enter the flight envelope and cause terrible consequences.

If it is a third-generation aircraft and uses fly-by-wire control, then there is no fear, and the flight control system of the fighter will prohibit the fighter from entering the misoperation.

In ordinary flight training, pilots would be careful and fly according to a predetermined subject, but now it is different.

Usually flying, everyone has to practice on the ground many times in advance, everyone holds the aircraft model in their hands, in the grass of the airport, several people's planes go back and forth, all kinds of flight actions, flight elements are memorized, practiced on the ground, before being able to fly in the sky.

After all, it costs thousands of dollars of oil to fly once, and the wear and tear of fighter parts is also terrible, which is also a domestic training method.

It's different abroad, their flights are very bold, and even when they fly confrontation, it is a real confrontation, if it's just to keep safe, they can't keep a strong national defense.

Now, Qin Feng was quickly dodging, and at the same time, he was secretly screaming in his heart.

Mustafa in the back also urgently dodged, and the two planes almost flew away by the fuselage, and the slightest collision would cause terrible results.

The sky is spinning, the fighter plane has been upside down in the air, Qin Feng just Ivan operated, the fighter first deviated to the right under the action of aerodynamic force, but then rolled to the left under the action of coupling force, and then, the entire fighter suddenly rotated around a certain axis.

The entire J-7 II fighter is buckled upside down, circling while continuing to descend, which is the most thrilling one of the tail spins, flying backwards tail spins!

According to the different types of tailspin, it is divided into many kinds, if the plane is entering positively, it is flying tailspin, and now the whole fighter is upside down, which is the inverted tailspin.

At this time, the huge negative overload lifted Qin Feng's body up, although they were wearing seat belts, their bodies were hanging upside down in the cockpit, and their heads were directly on the hatch cover.

If it's all blue sky and there's no reference, you won't feel dizzy yet. But now it was upside down, looking up at the cockpit, what he saw was the earth, and as the earth rotated, Qin Feng felt as if he had entered a huge vortex, and the plane was sucked into the abyss like twisted flowers!

After the fighter plane entered the tail spin, the speed of rotation and fall was getting faster and faster, just like watching a movie fast forward, and everything on the ground outside the cockpit became confusing, making people feel a sense of fear.

Qin Feng also chuckled in his heart.

I have always insisted on carrying out a tail spin test flight, but my superiors did not reply, who would have thought that this tail spin would suddenly come unexpectedly!

This is much riskier than a test flight into a tailspin.

Normal test flight, that is step by step, first a simple tail spin, explore the change, and then study the complex way of change, like the current inverted flight into the tail spin, that is definitely the last to fly a subject.

But now, I suddenly encountered it like this.

"Oh, the true God is above." Just after the two sides passed by, Mustafa took a deep breath, looked down, and saw Qin Feng's fighter plane spinning and falling, and immediately shouted: "Qin, skydive!" ”

At this time, he didn't care about the radio call rules.

As an experienced veteran pilot, as a predator who has participated in two wars, Mustafa also knows how severe the danger Qin Feng is facing now, flying upside down and tailspinning is the most dangerous situation faced by fighters, and few people can change it.

At this time, everyone in the control tower on the ground also gasped, and the monitoring radar here clearly saw the situation of the two fighters, one of which was spinning and falling, which was the most terrible stall tailspin.

Hearing Mustafa's shout again, he knew that it was Qin Feng who had fallen.

Who would have thought that such a serious situation would occur during the test flight of Egyptian friends.

"Skydive, let Qin Feng skydive immediately." Tu Lao said.

At this time, although everyone wants to protect the fighter plane and protect the country's property, it is no longer possible, no one has flown the tail spin to change out, and in the face of this situation, there is only one way to parachute.

Wang Gang shouted loudly on the radio: "006, skydive, please skydive immediately!" ”

Unconsciously, he remembered the danger Qin Feng encountered last time, how could this stubborn young man listen to the orders of the ground? He's going to have to think of a way to save the plane.

But now, he has not undergone special training, how can he change it? Once it fails, it will be a crash!

There was a constant sound from inside the earphones, at this time, Qin Feng, who was in a state of flying upside down, his body was being pressed on the side seat by a huge overload, the blood in his brain was surging, and his eyes were going to be congested, he used all his strength and shouted: "006 report, flying upside down, turning right, sixth circle, height of five thousand, I can change it!" ”

He had already signed up for a tailspin test flight, and this time he could try to change it, just now, he had been counting the number of laps of the flight, and at the same time judging the direction of the flight.

There is a trick to changing the tail spin, and the first step is to determine the direction of rotation of the tail spin.

Now, he had judged that the plane was spinning to the right and entering a tailspin, and he was trying to make a judgment, and at the same time, the plan for dealing with it echoed in his brain.

Since the plane rolls to the right, untrained pilots will subconsciously press the lever to the left to level the slope, which will actually make the tailspin dynamics more violent, and eventually it will never be changed again.

The correct maneuvering should be a flat rudder, the rod is neutral, and if the tail spin cannot be stopped, the lever can be pressed down.

It's like a pool with a plug opened, and as the water flows downward, it will rotate faster and faster, until a whirlpool is formed, and the tail spin of the fighter plane decreases, and the speed also increases.

When Qin Feng's voice was heard on the radio, the entire tower was silent.

Tail spin, it's actually tail spin!

This is an extremely risky subject, in ordinary flight troops, in order to avoid risks, the study of this subject has long been abandoned, after all, once it cannot be changed, it will be a crash and death.

If there is a kind of training aircraft, first with a flying tail spin, and then change it out, this is almost the same, but unfortunately, there is no suitable training aircraft for teaching in China.

Even if they are test pilots, many of them have only heard of them, and have not personally tested them.

Wang Gang clenched his fists, and secretly shouted in his heart that it was not good, this is terrible!

Once the plane crashes, this arms sale may also be in vain, and this is related to the interests of thousands of people in the 132 factory.
