Crashing an airplane is a stage that must be passed through in order for the design of a fighter to be finalized and to improve its technology.

Especially during the technical verification, no unit dares to guarantee that the aircraft they designed will not have any design defects after it is put into the sky.

If there are no defects in the design, who can guarantee that the production will be free of any defects?

"Lao Wang, are you kidding?" Zheng Yucheng looked at Wang Guilin, then at Xie Kai, anxious, "Other things, you can fool around, this matter is related to the dignity of the country and the face of the entire country's military industrial system." ”

"You look at me, like a joke?" Wang Guilin said seriously.

Usually, whoever wants to use the funds of the base, as long as they do not comply with the regulations a little, they don't want to get a penny from Wang Guilin.

Now this old guy is generous.

The price of the Super-7A, that's a thousand dollars a unit!

Although, the cost of production is not so high.

"Uncle Zheng, I'm really not kidding. If you believe me, listen to me. Xie Kai also had to pack the ticket, "As long as it can be completed, it is definitely not a problem to slap the Americans in the face." Even if it can't be completed, it is not a problem for Tu Lang to fly such a maneuver alone. ”

Xie Kai didn't say that Tu Lang flew alone, and he would never be as shocking as a five-plane formation flying a cobra maneuver at the same time.

What Yue Lin wanted to say, looking at this state, even Wang Guilin, the most difficult person to speak, had expressed his position, and if he wanted to oppose it, it would not have much effect, so he simply didn't say anything.

"Let Tu Lang come, it's okay, but we have to prepare another set of plans, otherwise, when the time comes, we will lose face and lose the face of the whole country. Yue Lin only said this sentence in the end.

In the current situation, no one can do better.

"What about Tu Lang's treatment? If you don't deal with it, you can't do it. Zheng Yucheng asked.

If you don't clean up the thorns, you will learn from them in the future, how to manage them?

This is the kind of thing that Zheng Yucheng can't tolerate the most.

Of course, it's not like this for everyone, he treats Xie Kai, that's the exception, who told Xie Kai to bring the entire 404 back to life from the brink of disbandment, and now it's a prosperous day?

As proposed by the country's top leader, a white cat and a black cat are good cats if they catch mice.

Obviously, Xie Kai is just a good cat.

"Punishment is a must, meritorious service must be rewarded, and there must be punishment. In the current situation, we can allow him to try first, and even if it can be completed in the end, he will still have to be punished for this kind of disobedience and serious disciplinary violations. Xie Kai said resolutely.

There are no rules.

No one is allowed to cross the rules.

Even if he Xie Kai, up to now, has earned tens of billions of dollars for the base, the big guys above look at him with a smile, not only does he not have any self-satisfaction, but he feels more pressure.

Even though he had money, he didn't dare to spend a penny, and he didn't dare to spend a penny indiscriminately when he could live according to his own ideas.

Even ripping off Mozzie's pants, he weighed it again and again, and finally convinced himself on the pretext that Mozzie was his daughter-in-law......

If decades later, he would have ripped off Mozzi's pants long ago, don't agree?

The overlord is the bow.

"Lead several other fighters to make this maneuver at the same time?" Tu Lang couldn't understand Xie Kai's going and returning at first, but after listening to Xie Kai's request, the whole person jumped up. "You'd better shoot me, you can't do this. ”

The cobra maneuvers, not everyone can fly.

Before Tu Lang did it himself, he had considered the consequences, either he would destroy the plane and kill people, and no matter how serious the consequences were, he would not be able to care about it, or he would go to a military court and never touch a fighter plane again for the rest of his life.

But now he told him that he was flying a Cobra with the other four Super 7A, and he felt that it was better to shoot himself.

"You have two options. The results of these two options vary greatly. The first is to refuse, the consequences are not serious, at most it is to go to a military court, and then there will be no chance of touching a fighter plane or even a flying machine for the rest of your life; the other is to agree to take them to fly, you have three days, no, to be exact, only two and a half days. It is necessary to ensure that the 5-aircraft formation makes a cobra maneuver at the same time, if it is completed, the punishment for violating the express order is still accepted, however, our leaders specially approve that you can drop one fighter every year, not only the current super-7A, but even the twin-engine super-7B that has begun to prototype trial. You can seriously think about it......"

Xie Kai ignored Tu Lang and prepared to leave after speaking.

Time is running out.

He didn't have any confidence in his heart.

Even if Tu Lang agreed, in the end, he couldn't see 5 Super -7A making a shocking action of cobra maneuvering at the same time, and it was all in vain.

Who would have thought that a fighter like the Super-7A, which is classified as a non-fighter type by Xie Kai, would have such maneuverability?

"Wait!" Tu Lang was anxious when he saw that Xie Kai was leaving.

Xie Kai stopped and turned his head to look at him, "What?"

"Can you really let me fly the Super-7B?" Tu Lang obviously knew about the Super-7B, and even looked at the model.

"It's up to you to behave. Xie Kai sighed, for some people, life can be wanted, and challenges are more important.

"Can you let me come for the first flight?"

"Dreaming!"

Xie Kai refused without even thinking about it.

The first flight of a fighter plane is extremely serious, and no one can agree with a person like Tu Lang who is fooling around at every turn.

The failure of the first flight will seriously damage the confidence of the entire R&D team.

The influence of human factors will be completely reduced to a minimum.

"There is no problem with flying any maneuvering?" Tu Lang also knew that the matter of the first flight had nothing to do with him in this life.

"It's up to you to behave. Of course, even if you fly all kinds of maneuvers, you must consult with the test flight team before taking off, and you will never be allowed to violate the order again. "Xie Kai is serious.

Tu Lang smiled bitterly, "If my superiors can agree, will I take such a risk!"

Xie Kai was about to leave again, this time he walked a long way before he was stopped by Tu Lang.

He didn't promise to succeed, only that he could give it a try.

Xie Kai was very satisfied with his answer, if Tu Lang said at the beginning that he could guarantee it, Xie Kai was not so relieved.

When Tu Lang appeared in front of his four colleagues again, the others were obviously shocked, and even showed contempt on their faces.

Xie Kai didn't interfere in their internal problems, but just followed behind Zheng Yucheng and them, and Yue Lin, who had a serious face, gave an order to the four Super -7A pilots with different expressions, asking them to fly the Cobra with Tu Lang.

Yes, this maneuver has been named the Cobra Maneuver by Xie Kai.

As for whether it is called Tu's Cobra maneuver, it depends on the effect.

"Guys, I know people don't like me very well. Super-7A, you all flew longer than me. This is an excellent fighter, the maneuverability is beyond our imagination......" Tu Lang didn't talk too much nonsense, "Of course, you are all better than me, this time it is not for my personal honor, but to win glory for the country, everyone knows that we will show on the same stage with the world's best air show team, if there is no new trick......"

"Why is he talking so much nonsense?" Zheng Yucheng asked Xie Kai.

Xie Kai shrugged his shoulders and spread his hands, indicating that he didn't understand at all.

In the end, I don't know how long Tu Lang said, the other pilots were all Hache for days, and Tu Lang ended, and instead applied to his direct leader Yue Lin, he had to fly a few more times to determine the parameters needed to enter this kind of maneuver.

Yue Lin didn't talk nonsense, and directly asked the ground staff to refuel and agreed to fly.

When the ground crew was refueling, Tu Lang took the initiative to ask that he could only add one-third of the fuel to the fighter, on the grounds that there was too much oil, and the weight would affect the fighter to make such a maneuver.

All things depend on him.

"Can he still do it?" Zheng Yucheng now does not have the courage to put all his bets on Xie Kai back then.

Give him another chance, he will not necessarily throw the limited funds that the base is not even enough to pay wages into the research and development of the numerical control system, so as to further agree that Xie Kai will go to Xiangjiang to find Pakistan and cut off the order of Hu 617.

At that time, 404 was on the verge of disbandment, and even if the bet was lost, the final consequence was only dissolution. Zheng Yucheng was even ready to die at the same time as 404.

And now, different.

Although this time it will not be as relevant to the life and death of the entire base as betting on Xie Kai back then, for people like Zheng Yucheng and them, national honor and dignity are better than everything.

The country is humiliated, and the people are disgraced!

What's more, people are coming to the door openly, just because China can't come up with a fighter with good performance.

Use technical strength to tell the Americans that your Chinese uncle doesn't need your garbage fighters, and our random training aircraft is better than your fighters!

Jung Woo-sung is looking forward to this.

"Look. Xie Kai also didn't have a bottom in his heart.

can only watch Tu Lang climb onto the cockpit of the fighter, from the moment the super-7A engine is ignited, Xie Kai's eyes have never left the J-7A piloted by Tu Lang.

The Super-7A slowly glides from the tarmac to the runway, then waits for orders from the terminal on the runway.

The plane slowly began to slide on the runway, the speed became faster and faster, and it ran less than 200 meters away, the nose began to rise sharply, as the speed became faster and faster, the nose was farther and farther away from the runway, and finally, at a distance of less than 500 meters, the main rear wheels of the super-7A were separated from the runway, and the whole aircraft showed a 45 ° angle to the sky and continued to climb.

The higher up the fighter, the smaller the size it sees.

But Xie Kai didn't dare to let Tu Lang take risks, when Tu Lang did this action before, the altitude of the plane was only 800 meters, but this time, the flight altitude, after being discussed by everyone, was set at 1800 meters.

If successful, lower the height.

It's not that Xie Kai doesn't want to set the altitude too high, but at an altitude of 3,000 meters, it is basically difficult for the fighter to see the movements clearly.

Tu Lang also guaranteed that it was enough at an altitude of more than a kilometer.

At 1800 meters, if you can't maneuver, the fighter enters a tailspin state, and there is more time to figure it out.

Super-7A continued to climb towards the sky, and eventually, began to circle at an altitude of 1,800 meters.

Without a telescope, you can't see it very clearly with the naked eye.

This time, Tu Lang did not play any more maneuvers, flew directly at level, and then slowly reduced his speed...... Everyone on the ground looked at the fighter plane in the sky, and the nose of the plane was raised several times in a row, but in the end they were not able to complete the Cobra maneuver.

"Can it be done? If not, let him come down. Neither the plane nor the people can afford to lose. Wang Guilin sighed.

Or do they think too much and expect too much.

Even Xie Kai was a little disappointed.

Looking at this situation, Tu Lang didn't seem to be sure.

"The nose of the plane is up again, oh my God, he succeeded......" After Xie Kai and the others put down the binoculars in disappointment, Mo Qi, who had been holding the telescope and paying attention to the action of the super-7A in the sky, suddenly jumped up happily.

Xie Kai hurriedly held up the binoculars and looked.

But I didn't see it, and the nose of the plane had already begun to press down horizontally.

However, without letting Xie Kai wait long, the nose of the plane was pulled up again, and the entire fighter remained perpendicular to the ground, even exceeding 90 degrees, showing a state of tail in front and nose in the back, and the whole state lasted for a few seconds, seeing that the fighter was about to fall down like this.

When the hearts of the people on the ground were raised to their throats, the nose of the fighter began to turn down again, and then changed to level flight.

A number of Cobra maneuvers were performed in a row, and some of them were unsuccessful during this period, but later, almost every time the Super -7A was able to successfully enter this maneuver.

"The speed at which the plane enters is about 424 kilometers to 428 kilometers per hour, and it is best to pull the control stick at 425 kilometers per hour, and the action must be fast...... At the same time, during the entire operation, the fighter was slowed down at a rate of more than 152 kilometers per hour, until it slowed down to about 110 kilometers per hour, and the push rod slammed into the nose of the aircraft...... "Tu Lang After dozens of experiments, and finally succeeded completely every time, he began to explain to several other pilots how to enter this maneuver.

In the evening, the other four Super -7As all followed Tu Lang's fighter into the air.

This time, the altitude of their experiment reached 3,000 meters.

Although it is not visible to the naked eye on the ground, it can be seen through the terminal.

All pilots are the elite of the domestic elite, and those who can serve as seed pilot instructors are definitely not ordinary people, with excellent psychological quality and exquisite skills.

In addition to the initial fear that the fighter plane would fall into a tailspin due to a stall, later, the pilots of several fighters successfully made a Cobra maneuver at an altitude of 3,000 meters......

"Not bad, not bad!" Xie Kai waited at the airport.

After learning that other pilots could do this maneuver, he let out a long breath.

After the plane came down, Yue Lin immediately arranged for the ground crew to carry out a comprehensive overhaul of all the fighters, and this kind of maneuver was a very severe test for the structural strength of the fighters.

"Xie Kai, I'll discuss something with you. I think we can have a more complicated ...... in front of the Americans" Tu Lang flew for a few hours, not feeling tired at all, seeing Xie Kai next to the airport, he didn't consider that the relationship between the two was not too familiar, he put his arm around Xie Kai's shoulders with a flattering smile on his face......
