Rule system

Power Engineering Lab.

Zhao Wei was caught by the alloy material of the turbine blade, but did not stop continuing to improve the engine's footsteps. He left the problem of turbine blades, continued and Yuan Haitao, Zhou Qing discussed the structure of the turbine.

The structure is the design.

The material of the turbine blade is hardfall, the most basic problem, which is directly related to the efficacy of the engine, but the design 'soft power' is also very important, directly affecting the performance of the engine.

The most important components inside the turbine are blades, and other gears, assist in rotation, and the blades are rotated, the blades, and other components are designed, and the coordination is coordinated to run the turbine.

The design of these complex parts is a very significant problem.

The R & D team of the Kunlun engine took out several programs, eventually selected one of the demonstrations, but in fact, because there is no reference, the components have been demonstrated and very complicated, and there is not enough atrioretical support. In the case of the final plan they take, it is not necessarily better than being eliminated.

So the most important thing is 'theoretical issue'.

Zhao Wei has no way to get a perfect program, because the data floating in the development plan is too large, resulting in a very large amount of computation, even if the top supercomputer, it is impossible to take the so-called 'perfect program' .

When it is found that it is unable to take a complete set of design, it simply determines the perfection of a little bit, for example, in the case of accepting the turbine blade design, expanding the part next to the side, a little slowly perfect, until the last one part.

This approach does not necessarily get the most perfect solution, but the program derived is definitely higher than the existing design effect.

Zhao Wei and Yuan Haitao, Zhou Qing said a while the problem of turbine, and then made a decision, "first dismantled the turbine, all disassembled, I took a closer look."

Yuan Haitao took force to pull his mouth and hesitated. "Is there a design picture?"

"The design is not intuitive."

Zhao Wei explained that "only the structure of the inside is really seen," can you know better. "

Yuan Haitao and Zhou Qing have opposed an eye, and they can only say hard, "demolish! Demolition!"

"Remove it!"

Both people can't understand.

The turbine and combustion chambers are connected together, but they are two components, and the test is also separated. It is still acceptable, and the turbine is a component, just like a car engine, it has been dismantled Oh, it also removes the pressure and the shaft part is meaningful?

View Parts Composition?

But there is a picture on the engine design ...

Zhao Wei is not in the idea of ​​the two, he wants to disassemble and see if you get more conditions to improve the design, because there is a new design plan, the prototype is also completed, whether it is not in assembly Big.

So he didn't feel pain at all, and the exciting participation was involved in the disassembly work.

It is like a unknown mechanical toy. I want to know what I have to take a look, the process is still very interesting, every time I remove a part, I will get carefully.

Zhao Wei's more dismantling, the more I feel interesting, and then I simply let people teach themselves, he will do itself to do the disassembly work, remove the rotating shaft inside, and also understand a novel accomplishment.

"really interesting……"

"So, when men still have to engage in machinery, we must see more news, a certain homemade rocket, a self-made machine, what is the meaning of what is made, the key is the process ... ... Well, very interesting. "

Others can see it.

Yuan Haitao looked at Zhao Wei's spiritual participation in dismantling, even grabbed the work of others, couldn't help but mutter, "Zhao's academician decided to dismantle the turbine, will not be ... Play?"

Another forty-year-old engineer, Xue Fengzhen, just came over and heard Yuan Haitao, immediately shake his head, "Yuan team, I see, Zhao's unspeakable, every part, what is the use, understand the specific Principle. He has always been very serious. I look ... "

Xue Fengli listened, affirmed, "He wants to design a turbine program and make one out."

"what?"

Yuan Haitao really didn't think.

Although I have always discussed the problem of turbine, he just thinks that it is to discuss design, find out where there is a problem, record it, it will be possible.

Is it your own design plan, do it yourself?

is it possible?

The Kunlun engine has a R & D group in designing turbines, the turbine research and development group initially has seven, eight people, follow-up to change into a team of more than a dozen people, has been working for more than ten years.

After the Kunlun Group successfully created the first prototype, the Turbo R & D group was reorganized to the R & D base in Wutheng, which directly became a department, named Wucheng Air Turbine Group.

The work of this R & D group is to develop aviation turbines. Of course, their research and development is not only designed, including the material of the turbine, but all the alloy material has not progressed, but in any case, the work of their group is the turbine. Research.

right now……

"Zhao's unique person, even if we have four people, how can it be designed to design a turbine!"

Yuan Haitao felt that he heard a joke.

Xue Fenggu said, "Zhou Qing knows less on the turbine, I am also not good at engage in research and development, Yuan team, you don't ..." He said to stop, continue, "cough, you will be a little, you and Academician Zhao, two people. "

"Anyway, no matter what to say, I feel that the academician Zhao is ideal, and that is the University of Zhao!"

Yuan Haitao listened to the sorrow, said, "anyway, it is not important, we can work with work."

"Right."

The work they have been explained is to cooperate with Zhao Wei. As for what Zhao Wei wants to do, the discussion is meaningless.

......

The removal of the turbine is not difficult, but the process is very troublesome, because some parts are heavy, the number of parts is also a lot, and they are cumbersome.

At a more than a little more, Zhao Wei and two workers took the most important turbine blades in turn. There were sixty turbine blades inside the turbine, and each piece was very fine, and it seems to be able to do it. Turn into a sharp knife.

"This blade is not easy to grind into a knife."

"The intensity is very high."

Yuan Haitao suddenly took a sentence, and some other people have seen it. He is a bit embarrassed to explain. "A few years ago, there was a scrapped fighter, and I have dismantled a blade, go back. I plan to grind it. When the knife is used, the result is worn for a long time, and it is a little black, and it doesn't work. "

"This is still a turbine blade in the fifty-year, and now this leaf performance is a bit no bid, but it is definitely higher than that."

Others listen to the laugh, "this way."

"Yuan team, you really have ideas."

"This idea is actually very good, take a knockout of the blade to go back to the knife, must be used without bad, but it is a problem, it is estimated to find a professional place."

"To go to the laboratory of manufacturing alloy materials, or anything else ..."

Zhao Wei did not participate in the discussion, just to listen to it, he also felt that the idea was very good, looked at the leaves placed on the ground, he also thought about there is an opportunity, find a few pieces to grind, it is best to grind into one The shape of the knife.

Otherwise I will find Zhang Hongtao to customize?

Fruit knife, kitchen knife, etc., high-strength nickel alloy tools, look high.

I want to Cao Cao, Cao Cao can also come!

Zhang Hongtao came.

There is a guard in the outside, and Zhao Yu hits, "Let him come in, he is an expert in alloy materials!"

After Zhang Hongtao entered the operation, Zhao Wei took him to the office, and quickly entered it, and discussed the technical issues of turbine blades.

Zhang Hongtao is too much in Yuan Haitao. He did not have the study of turbine blades. It is also very professional. "As far as I know, our domestic homemade aerospace engine is also Kunlun and the house, the turbine blades used, should be A nickel iron alloy material is the results of the original Institute of Metals. "

The Turbine Jet Engine is developed by the Turbine Jet Engine, which is based on the technology of the Kunlun project team, and the prototype has also been produced.

"Now China's aerospace engine technology, one of the biggest difficulties is the turbine blade, turbine blade material is a big problem, the Institute of Metal Research Institute, the capital of the Academy of Sciences, and the relevant project research, which also has a certain results. It is DD5 and DD6. "

"But DD5 and DD6 are the second generation of single crystal nickel alloys. In fact, there are three programs of nickel alloys, one is a single crystal nickel alloy, one is a polycrystalline nickel alloy, and the other is nickel-iron alloy."

"When the initial study, the determined direction is a single crystal nickel alloy, the first generation of nickel alloy in China is also a single crystal nickel alloy. Now is the second generation, only the performance can not keep up, or continue to study."

Zhao Wei asked, "other programs?"

"Now use of nickelin alloy, because existing nickel-iron alloy, high temperature resistance, higher strength. And DD5 and DD6, high temperature resistance is not bad, but the strength is slightly different."

Zhang Hongtao said, "Although the technology of domestic nickel iron alloy is better, the main direction of research is definitely a single crystal nickel alloy, because there is a trailer, M country, their turbine blades are single crystal nickel alloy."

"This."

Zhao Wei is over.

Existing nickel-iron alloy manufacturing technology is better than single crystal nickel alloy technology, but there are technologies for more than ten years ago, and now there is no improvement, development, and wants to further be very difficult before.

Single crystal nickel alloy is not the same.

The international top turbine blade is used by single crystal nickel alloy, which is equal to the success of the previous, and the research and development can see the hope is very important. The research direction of the nickel-iron alloy can be said that there is no reference object, the research road is still I can slowly explore myself, the single crystal nickel alloy has a successful object, and the goal is always going forward, and it will definitely improve

The difference between the two is here.

Therefore, the nickel-iron alloy is used is used, and the main direction of the study is a single crystal nickel alloy.

"Single crystal nickel, is indeed a place."

Zhao Wei has seen a lot of information, which is still aware of this, and 'single crystal' refers to the lattice position of the crystal to the same, and it is understood that the internal atomic arrangement is completely consistent.

Such crystals are resistant to high temperature resistance, and the intensity will become higher.

From the principle of shaping, the starting point of the single crystal alloy must be high.

Zhao Wei and Zhang Hongtao have discussed some of the technical issues. "I want to improve the turbine, I hope to break the difficulties of this alloy material. Are you interested in cooperating with me, let's ..."

Zhang Hongtao did not wait for Zhao Wei to finish, nodded, "Cooperative research is no problem, I can represent metal composite laboratories, but ..."

"but?"

Zhao Wei wrinkled slightly.

Zhang Hongtao immediately said, "It's like this, I have been thinking before, let's work together, there is no problem, but there is a problem on the application item."

"What's the problem?"

"This is a big project, super big project." Zhang Hongtao explained that "you think about it, only the Institute of Metal Research Institute and Aviation Materials" of the Academy of Metals are doing, if the application is not applied in the name of the metal composite laboratory. Down, don't say that it is believed that it is a problem. "

Zhao Wei wants to say, "How much to do this study."

"Tens million?"

Zhang Hongtao said a number, sounded some incredible, he explained, "mainly raw materials. Rare metal is very expensive, do the research loss is very big, I will tell you,, is equivalent to gold, platinum, market Both is the top of 'gram', but many people know that the top turbine blade materials are definitely. "

"These metal raw materials are the most cost-effective, our metal composite laboratories are also focused, but this project unless the entire laboratory is applied, otherwise ... no hope."

Zhang Hongtao said, then I thought halfway, "In fact, there is a way. For example, you also have a department, can you hang in the air turbine group? Anyway, you are also the special people in the Kunlun group, is also the people inside."

Zhao Wei thought about it, "I don't want others to insert research, and hang in the turbine group, it is estimated that research is going to Wune City?"

"Correct."

Zhang Hongtao sighed, "But there is no way, our laboratory can not apply, it is best to cooperate in two laboratories, and apply with the name of the two research institutions."

"Just have the opportunity?"

Zhao Wei listened to Zhang Hongtao and felt that there was reasonable. The research certainly needed to support it. It is best to apply for the project, otherwise it will not be able to spend money, can't find the materials used.

He shook his head, "Zhang Ge, this way, I think again, I have decided to call you."

......

When I went to the door, I walked away from Zhang Hongtao. Zhao Wei walked in the way back. I thought carefully. He wanted to study the turbine blades, but I don't want to work in Wucheng, and I don't want other institutions, others insert research.

How to do?

Zhao Wei slowly went to the school, and the door met Hi Hua. "" Teacher, do you know our students, have a laboratory with materials? "

"Materials science?"

Gao Zhixuan thought about it, "The material engineering of our college is a new professional?" He said with a joke, "said that he had a graduate student with an exteration of an external professor last year.

"... count!"

"what?"

Zhao Wei is head, "If you have it! I will turn a circle, ask the name, try."

"What do you say? Try?"

......

At 8 o'clock in the evening, Zhao Wei called Zhang Hong Tao, saying that he decided to join the "Yanya University Metal Material Laboratory", and cooperated with the metal composite laboratory of Aeronautics and Astronautics, together with the 'Turbine Blade Materials R & D' s project.

Zhang Hongtao listened, "What labs do you say?"

Metal material laboratory. "

"Isn't that our laboratory?"

"No." Zhao Wei correctly said, "Your name is a metal composite laboratory, we don't 'composite' two words."

"Are you sure not kidding?"

"I'm serious."

"But if I want to apply for this, I am estimated that I will come back ..."

"It doesn't matter.

"……Ok."

Zhang Hongtao said very helplessly, "But don't you consider change your name?"

"No, I think it is very good, I want to be too much trouble ..."
