The military-industrial scientific research system of the academic master

The follow -up work of the CTK series of pushing agents and remote air defense missiles is of course handed over to Lin Chenggang and Shen Fangzhong. They are responsible for them.

Chang Haonan:

"I have a lot of things, I have to put my energy on the hypersonic weapon!"

Nympho

Actually, after the theory of width -speed multharine wave body configuration is proposed and verified, the gliding superb project has entered a relatively fast track.

However, from theoretical research to engineering development, it still needs a stage to transition.

This allowed Chang Haonan to take a few days in a busy way, and returned to the Torch Lab to solve a small problem.

But after that, the work intensity of the entire R \u0026 D team will reach a new level.

The most critical of them is naturally the design of the wave body structure.

Although the overall solution of the wide -speed domain design has been determined, for the specific implementation, and some of the details, the entire project team, including Chang Haonan himself, is still a bit tangled.

The surface of the fixed wave body is used to adapt to different speeds by changing the under -surface contour through the toss -type rectifier. This is the initial and the most basic idea.

Simple and intuitive.

But it is a clever choice.

Because in the final analysis, it is to optimize the aerodynamic characteristics of different speed intervals by pre -production of various configurations in advance.

If one of the configuration is out, the scope of adaptation is still relatively narrow.

Of course, there is a more direct problem.

In general, the faster the flying speed of the wave body, the more the corresponding compressed surface contour is raised down.

And if you use a streaming cover, it is limited by the problem of spatial utilization, and the lower surface can only be flat and flat.

That is, the raised rectifier package wraps a relatively flat fixed surface.

Corresponding to the flight process first and then slow.

There is no problem in the verification phase.

But if you put it in this way, there is still a bit stiff.

Although in order to improve the accuracy of the hit, the missile does reduce the speed at the end. Generally, it is in line with the trend of fast first and then slow, but the speed of gliding is not the same in the process of "water drifting". Multiple conversion with gravity potential energy.

When slowing down, you can throw away the rectifier. When the acceleration is accelerated, the throwing rectifier cannot be picked up and reinstalled, so the adaptability of the whole process is still not ideal enough.

What's more, Chang Haonan's long -term ambition is to make the multiplier structure into a repeatable aircraft, which requires a long gradual acceleration process.

Therefore, this design is ultimately just as a guarantee plan.

If all subsequent designs are proven to have problems, then take it out, at least ensure that the entire project is head and end.

"Since the throwing rectifier is not flexible enough, what if it is designed to be variable?"

Fu Changsheng, the director of the overall design department, almost followed the proposal.

"Variable?"

This ranking is obviously unexpected by most people here.

Xing Muchun also said in a half interesting manner:

"Director Fu is ... don't forget your original intention?"

Fu Changsheng, like Chang Haonan, was also born in the field of aviation, and in his early years, he also participated in the development of 6 strong aircraft and the reverse surveying and mapping of the MiG 23 fighter.

From a population with such experience, the variable structural design is proposed, and the evaluation of Xing Muchun is indeed appropriate.

For a while, the tension at the conference room was diluted a lot.

"It's right to say that."

Fu Changsheng also smiled and touched his head:

"There are some influences in the early years ..."

Speaking of which, he suddenly came to a turning point:

"But my plan is definitely serious."

As soon as this remark came out, everyone in the laughter and laughter also became serious.

"Although I do heard that the 611 plans to use flexible skin to make the drum bag of the four -generation DSI air intake, but I can only adjust it within a relatively small range ... Our wide -speed range multiplied by wave body The two lower surface differences are still quite large, it is unlikely to be realized by the adjustment of skin, right? "

Fu Changsheng glanced at Chang Haonan, who was sitting on the main position, and saw the latter that he listened carefully, so he continued to continue:

"I have also considered flexible skin materials, but it is more sensitive to temperature and cannot support thermal load and pneumatic load under the hypersonic conditions. Therefore, the mechanical structure is still required ... for example When flying relative to low -speed flight, the wing is extended, providing lift with the lower surface, and the wing is adopted into the inside at high speed and turned into a pure ride.

Jiang Zonglin, who was just exposed, did not participate in the design work in principle:

"Really want to change the wing?"

F14 and Figure 160, which came back through different channels, can make up for the small regret that Huaxia has not been equipped with a wing aircraft.

But in the 21st century, it is still a hypersonic speed ...

It's a bit abstract.

"It is right to say that it is also the same as the plunder wings, but it is not a traditional slide structure."

Fu Changsheng explained:

"For example, some mechanical super materials can show different morphological conversion features when they are tensile in different directions. It is very suitable for this wing structure with only two formal changes ..."

There is no mistake, one, one, one, one, one, one, one, one 619, one book, one, one, one, one, one, one, a book!

"..."

For a while, for this that it sounded a bit outrageous, but if they thought about it, they seemed to be quite reasonable, and everyone launched a fierce and wonderful controversy.

Until Chang Haonan cleared his throat and was ready to speak.

The conference room was quiet.

"I have happened to have some research on calculating materials recently ... Although mechanical super materials are a recent relatively popular research direction, the research at the specific application level has just started. For us, the risks brought by new technologies are a bit big ... ... "

In fact, there is no need to continue to discuss.

If even Academician said that the risk of your plan is a bit big, it must be really big.

Therefore, everyone did not answer, but waited for him to speak further in the future.

"Actually, sometimes there is no need to think too complicatedly ..."

Sure enough, Chang Haonan said slowly:

"We can directly blend the multiplication of the two designs of Mach high and low, and some of which are designed with a high ejaculation of the cruise condition. Wave body, connect with an adapter in the middle ... "

"Then stretch the upper and lower surface of the upper and lower surfaces of the wave to form a horizontal stretching body. The left and right sides are equipped with a wave wing.

As his ideas gradually improved, the entire project team finally began to operate at full speed.

Under the efforts of hundreds of members of the design department, the project plan finally came down the design drawings before the end of 2007.

However, there is still the last job to be completed before the real testing.

The gliding superiority has no motivation itself, relying completely on a ballistic missile to provide sufficient initial speed and height. Therefore, in addition to its own development work, it is necessary to develop the two -tapered physical demonstration when developing a double -tapered physical demonstration. Of course, there are essential coordination of the second artillery.

After all, due to volume problems, she can only be equipped with special missile troops.

Jing Zhiyuan, who was the commander of the second gun, was waiting for this time.

For this reason, he also specially took out some time, specializing in the relevant knowledge about the wave body and the hypersonic aircraft.

Although I didn't understand it in the end, at least there was some basic concepts.

Jing Zhiyuan is confident, no matter what kind of solution Chang Haonan moves out, he will not feel too shocked.

However, when he really came to Huairou Science City and saw the other party reported the schematic diagram of the 3D rendering ...

All preparations look so pale at this moment.

"Academician Chang ..."

Jing Zhiyuan couldn't help taking a deep breath:

"Your missile ... how to design it like an airplane?"
