The Air Force started with the repair of fighters

Chapter 263

On Li Rui’s side, he couldn’t even care about eating, so he had already contacted the people from the Research Institute of the Southeast Military Region.

After getting the exact answer and the problem of determining the heat resistance and strength of the turbine blade has been overcome, he was very excited and directly finalized the time with the other party, and Li Rui personally led people to bring back the new turbine blades that had been transformed.

He calculated in his heart that in this way, in terms of time, he could not save time.

Li Rui inexplicably has a feeling that after Xiao Yun’s arrival, the DF-17 will soon be able to conduct shock wave wind tunnel tests again.

On the first day that Xiao Yun arrived at the DF-17 research base, he solved the problem of the engine, and this news swept the entire research and development base like a violent wind.

Li Rui knew from the population at the Southeast Military Region Research Institute that Xiao Yun alone solved the problem of turbine blades.

Xiao Yun’s side, after eating, under the leadership of Chen Kang, went to the place where the DF17 testing machine was placed.

Inside the huge warehouse, the DF-17 was quietly placed.

Xiao Yun’s face could not hide his excitement, and he walked in quickly, almost impatiently walking around the DF-17.

Because the DF-17 in front of him is only a test machine and has not yet been officially commissioned, the warhead is not marked with an exclusive DF-17 letter.

Rao was so, Xiao Yun’s heart was still amazed.

DF-7 hypersonic guidance, its own shape flying peculiar, and ordinary cruise missiles or ballistic missiles are clearly different.

Its head is designed with a special aerodynamic layout, somewhat similar to an aircraft in the atmosphere, and four aerodynamic rudder surfaces, which are somewhat similar to the design of a rocket.

Hypersonic missiles, only with the ability to exceed 25 times the speed of sound, are because the DF-17 missile uses the principle of flying by wave.

You know, the advantage of hypersonic missiles is not only the flight ability to tell, but also the fact that this aircraft can maneuver and fly.

This is very different from ballistic missiles.

Ordinary ballistic missiles, at the initial stage, already determine the ballistic characteristics, while hypersonic vehicles can continue to change orbit in the atmosphere, and more importantly, its trajectory is unpredictable.

Although the DF-17 in front of you is still in the final state of development and adjustment, its power is already visible.

“Xiao Xiao, how is it? You also saw the DF-17 test machine, do you have any thoughts in your mind? ”

Chen Kang followed Xiao Yun’s side, but he didn’t have time to introduce anything to Xiao Yun, and since entering this base, the excitement on Xiao Yun’s face had not been concealed at all.

Seeing that Xiao Yun actually dragged his chin with one hand after circling around the DF-17, his brows were slightly wrinkled, and he fell into a state of deep thought, Chen Kang still opened his mouth to ask.

You know, Chen Kang himself, facing the time of the testing machine, he felt that his head was amused, and he couldn’t see anything that needed to be improved.

At this time, Xiao Yun had already turned on the all-round scanning state.

Because the DF-17 had already assembled the composition of the department, he needed to scan it himself before he could find the problem again.

“Chief Engineer Xiao, thank you so much, you have brought us a qualitative breakthrough!”

Li Rui walked in from outside, walked directly in front of Xiao Yun, and praised him with a smile.

If Xiao Yun hadn’t come over, their DF-17 R&D base would never have known that the technical problems of turbine blades had been overcome, and they were afraid that they would still have to rack their brains to study how to solve this problem.

“Deputy Chief Engineer Li is polite, I just did what I should do.” Xiao Yun was very modest and did not take credit.

“Young and promising, young and promising!”

Li Rui and Chen Kang looked at each other before sighing and saying.

“Director Chen, Deputy Chief Engineer Li, the speed of DF-17, I don’t know how many Mach it has reached now?”

Xiao Yun finally finished reading all of the DF-17, and after thinking for a while, he asked.

The starting threshold of hypersonic missiles is Mach 5, and after looking at all the constructions according to Xiao Yun, he has concluded that the DF-17 test at this time, the highest speed, should be able to reach Mach 8.

Such a speed can already be said to be fast enough. According to the current strength of the anti-missile system, it is completely impossible to intercept.

However, Xiao Yun knew that this speed, in fact, could be increased again.

“At present, after previous shock wave wind tunnel tests, the maximum speed that the DF-17 tester can achieve is Mach 8!”

Li Rui first answered Xiao Yun’s question. At the same time, he looked at Xiao Yun’s gaze with a hint of fiery.

Just by looking at the DF-17 testing machine, this raises the key speed question, how can he not think more?

“Xiao Xiao, is there something wrong with this speed?”

Chen Kang looked at Xiao Yun, a little puzzled, he was more familiar with Xiao Yun, since Xiao Yun asked this question, it must be that Xiao Yun had other ideas, and it was definitely an idea that could definitely improve the speed.

When it comes to the question of hypersonic missile speed, its own characteristics are fast speed and high maneuverability.

The most obvious contrast between hypersonic missiles is intercontinental missiles.

The speed of the ICBM can reach Mach 20 at the fastest, but due to the problem of mobility, the ICBM can still be intercepted by the anti-missile system at a speed of Mach 20.

ICBMs are ballistic missiles, relying on inertial guidance and gravity to fall, and the trajectory is set at the beginning, so it is easier to predict, which is the basis for interception by anti-missile systems.

DF-7 hypersonic guidance, its trajectory is not a “conformist” setting, but erratic, coupled with a speed of 8 horses, the anti-system has no way to intercept at all.

“There is no problem with speed, but, I think, this speed can be increased a little more, to Mach 10, not a problem!”

Xiao Yun said with a serious face.

His words fell, and Chen Kang and Li Rui were both stunned.

Li Rui’s face was flushed.

“Chief Engineer Xiao, you are still young, you may not understand the gap between the speed of Mach 8 and the speed of Mach 10, the current speed of 8 kHz, after the overall test, it is impossible to improve!”

Li Rui suddenly felt that Xiao Yun was still too young to dare to say anything.

“Deputy Chief Engineer Li, the trajectory of the DF-17 itself is erratic, not the same as ballistic missiles, I think that on the basis of this theory of “Qian Xuesen’s ballistics”, it is completely possible to increase the speed of the DF-17 again! “_
