The Air Force started with the repair of fighters

Chapter 264

Compared with Li Rui’s excitement, Xiao Yun was really indifferent, his face was calm, and there was no wave.

His words were like a stone dropped in the calm lake, causing strong waves, so that Li Rui and Chen Kang did not know what to say for a while.

Chen Kang’s body trembled slightly, this was the result of being too excited, and he had no way to control his mood swings.

Because when Xiao Yun proposed the speed, he already had a vague guess in his heart, so he would not show too much praise now.

Even so, he still couldn’t control his emotions!

Li Rui was even more exaggerated, he was directly stunned, just looked at Xiao Yun so stupidly, he couldn’t say a word, and his body became stiff.

“Good boy, what you said earlier about chatting with that guy from Cao Xi is actually the speed of the DF-17, right?”

After a long time, Chen Kang finally reacted.

He thought of Xiao Yun’s performance at the Northern Research Institute, and mentioned the problem of “Qian Xuesen’s ballistics”. Now that I think about it, I am afraid that Xiao Yun had an idea about the DF-17 at that time.

Suddenly hearing Cao Xi’s name from Chen Kang’s mouth, Xiao Yun was stunned for a moment, only then remembered what he said at that time, and returned the pot to Director Cao Xi to carry it.

“Yes, I did talk about some issues at that time, and I couldn’t confirm anything at that time, after all, I haven’t seen what the DF-17 test machine said with my own eyes, it’s just theoretical knowledge.”

With the system as an artifact, Xiao Yun is not afraid of anything.

The DF-7’s missile trajectory itself is inspired by the theory of “Qian Xuesen’s ballistics”, and it is also based on this point of development.

The “Qian Xuesen ballistics” theory, to sum it up simply, is to use the waverider warhead to allow the missile to jump in the atmosphere, which is also like “hitting the water”.

The current DF-17 is a waverider warhead.

“In the waverider warhead, a vector nozzle is installed to ensure that a large lateral maneuver can be carried out at any time, so that with the cooperation of each other, the speed will be increased faster, and the speed can be guaranteed to be at least Mach 10!”

Xiao Yun gave an accurate solution.

“Install a vector nozzle inside the waverider warhead?”

I have to say that Xiao Yun’s thoughts made Li Rui and Chen Kang have a refreshing feeling.

The waverider is a shape suitable for hypersonic flight, and all its leading edges have appendage shock waves. When the wave-riding body flies, its leading edge plane is heavy with the upper surface of the shock wave. Like riding on the surface of the shock wave, relying on the pressure of the shock wave to generate lift,

Therefore, the shape of the warhead is designed as a waverider body, maximum resistance, high lift, high lift-to-drag ratio, no flow field interference on its upper surface, no streamline deflection, and the shock wave is limited to the leading edge of the shape, so that the high pressure on the lower surface of the pressure zone is combined with the upward inclined shape to obtain the entire external thrust component.

Precisely because the waverider warhead already has enough lift, no one thought that it was possible to install an additional vector nozzle inside the warhead.

After figuring this out, Li Rui and Chen Kang couldn’t stay, and with a new research and development direction for DF-17, they certainly had to improve it according to Xiao Yun’s method.

“Mr. Xiao, I think you are simply born for scientific research. You can wander around yourself, I will arrange it, build the DF-17, and after the modification, then conduct shock wave wind tunnel testing! ”

Chen Kang stepped forward, patted Xiao Yun’s shoulder, and after dropping this sentence, he left directly in a hurry.

The point put forward by Xiao Yun made the entire Northern Research Institute busy.

The only person who is relatively idle is Xiao Yun.

Time, in such a leisurely way, slowly passed.

A week later, Xiao Yun had just gotten up and saw Li Rui standing outside the door.

“Chief Engineer Xiao, go quickly, we have re-modified the DF-1, the turbine blades use the latest type, in addition, the warhead of the waverider body is also installed with a vector nozzle, today, is the time for the DF-17 to conduct shock wave wind tunnel testing again, Chen Suo they have passed first!”

Li Rui hurriedly said to Xiao Yun, and then took his arm and walked in another direction.

Xiao Yun sighed, he felt that these researchers were simply too frustrated, and did not give themselves a chance to eat.

Although he sighed in his heart, the pace under Xiao Yun’s feet did not slow down at all, and even later, he was dragging Li Rui forward.

After leaving the base, they got into the car, and the car sped away, afraid that if they slowed down, they would be scolded by Li Rui.

A few hours later, Xiao Yun and Li Rui appeared at another base.

Here, is the Shock Wave Wind Tunnel Laboratory.

“Chief Engineer Xiao, let me introduce you, this is the head of the shock wave wind tunnel laboratory, Zhang Feng.” Li Rui took Xiao Yun to a monitoring room and brought him to a middle-aged man who was staring intently at the big screen, and introduced him seriously.

“Zhang Feng, this is Xiao Yun, Chief Engineer Xiao, he is powerful, this time DF-17 can conduct shock wave wind tunnel testing again so quickly, but it is all his credit!”

Li Rui and Zhang Feng were old friends, and in front of him, they also praised Xiao Yun without hesitation.

“Young heroes, I said old Li, you old people, in front of young people, can’t do it!”

Zhang Feng looked at Xiao Yun fixedly for a while, his eyes full of appreciation, and then he said ridiculously to Li Rui.

It was the first time he had heard Li Rui praise people like this, especially since the other party was still a young man who looked to be only twenty years old.

Zhang Feng couldn’t even help but think in his heart, is he really old? It’s already a bit out of step with the times.

“Okay, we old guys, but we can’t compare with young people. Let’s go, let’s take another look at the DF-17 test, and then officially start the shock wave wind tunnel test! ”

Waving his hand, Li Rui admitted that he was incomparable to Xiao Yun anyway.

A few people chatted idly and walked into the warehouse where the DF-17 was placed.

“This blade-like DF-17, after it is officially put into service, it will be a well-deserved blade for our dragon country!” Although he has seen the DF-17 many times, every time he sees it, Zhang Feng still has to sigh.

“Release mission: Repair the DF-17 hypersonic trajectory before it is tested in the shock wind tunnel to complete this shock wind tunnel test!”

“？？？” The system suddenly appeared, and Xiao Yun’s mind was full of question marks. This thing, finally upgraded completed? _
