Rule department scholar

This approach does not necessarily lead to the most perfect solution, but the resulting solution is definitely more effective than existing designs.

Zhao Yi talked with Yuan Haitao and Zhou Qing about the turbine problem for a while, and then made a decision and said, "Let's dismantle the turbine first, take it all out, and let me take a closer look."

Yuan Haitao tugged at the corner of his mouth and said hesitantly, "Isn't there a design drawing?"

"The blueprints are not intuitive."

Zhao Yi explained, "Only by taking it apart and actually seeing the structure inside can we understand better."

Yuan Haitao and Zhou Qing looked at each other, and they could only say forcefully, "Demolish! Demolish!"

"Take it up and take it apart!"

Both of them were a bit incomprehensible.

The turbine and the combustion chamber are connected together, but they are two parts, and they are tested separately. It is acceptable to take them apart, but the turbine is one part, just like a car engine, and the burning place has been disassembled What's the point of dismantling the pushing and rotating shaft parts?

View component composition?

But the engine design drawings have it all...

Zhao Yi didn't care what the two of them thought, he just wanted to take it apart and have a look, so as to get more conditions to improve the design plan, because with the new design plan, the prototype can be regarded as having completed its mission, whether it is meaningless in terms of assembly big.

So he didn't feel distressed at all, and instead enthusiastically participated in the disassembly work.

It's like getting an unknown mechanical toy. If you want to know what's inside, you can dismantle it and have a look. The process is still very interesting. Every time you dismantle a part, you have to take it out and look at it carefully.

The more Zhao Yi disassembled it, the more interesting he found it. Later, he simply asked someone to teach him how to dismantle it. He did the disassembly work by himself. When he removed the shaft inside, he also felt a novel sense of accomplishment.

"really interesting……"

"So, men still want to engage in mechanical things from time to time. No wonder there are so many news reports that such and such homemade rockets, such and such homemade machines, etc. It doesn't matter whether the things they make are meaningful or not. The key is the process... …well, interesting."

Others don't see it that way.

Yuan Haitao watched Zhao Yi participate in the dismantling work energetically, and even grabbed other people's work, and couldn't help muttering, "Academician Zhao decided to dismantle the turbine, isn't it just for... playing?"

Another engineer in his 40s, Xue Fengge, happened to come over and heard Yuan Haitao's words, and immediately shook his head and said, "Team Yuan, let me see, Academician Zhao is very serious, and ask what is the use of each component, to understand the specific principle .He has been very serious. Let me see..."

Xue Fengge listened for a while, and said affirmatively, "He wants to design a turbine plan by himself and build one."

"what?"

Yuan Haitao really didn't expect it.

Although he has been discussing the turbine issue with Zhao Yi, he just thinks that it is to discuss the design plan, and if there is any problem, he will record it and submit it.

Now you design your own plan and do it yourself?

is it possible?

Kunlun Engine has a R&D team designing turbines. The turbine R&D team originally consisted of seven or eight people, and later adjusted and changed to a team of more than a dozen people. It has been working for more than ten years.

After the Kunlun group successfully manufactured the first prototype, the turbine R&D group was reorganized into the R&D base in Wucheng and directly became a department called Wucheng Aviation Turbine Unit.

The job of this research and development group is to develop aviation turbines. Of course, their research and development is not only about design, but also includes the materials of turbines, etc., but the alloy materials have not been developed, but anyway, the work of their group is the development of turbines. Research.

just now……

"Academician Zhao alone, even with us, there are only four of us, how can we design a turbine!"

Yuan Haitao felt that he heard a joke.

Xue Fengge said, "Zhou Qing doesn't know much about turbines, I'm not good at R&D, and neither do you, Team Yuan..." He paused, and continued, "Ahem, only Team Yuan knows a little bit, you and Team Yuan Academician Zhao, two people."

"Anyway, I think Academician Zhao has ideas, and that's Academician Zhao!"

After hearing this, Yuan Haitao pursed his lips and said, "Anyway, it's not important, we just need to work together."

"Right."

The job they were given was to cooperate with Zhao Yi. As for what Zhao Yi wanted to do, there was no point in discussing it.

……

It is not difficult to disassemble the turbine, but the process is very troublesome, because some parts are very heavy, and the number of parts is also large, and it is very cumbersome to place them separately.

At one o'clock in the afternoon, Zhao Yi and two workers took off the most important turbine blades one by one. There are sixty turbine blades inside the turbine, and each piece is made very finely. Become a sharp knife.

"It's not easy to sharpen this blade into a knife."

"The intensity is very high."

Yuan Haitao suddenly said something, and everyone looked at it immediately. He explained a little embarrassedly, "A few years ago, there was a scrapped fighter plane made in the Soviet Union in the 50s. I removed a blade and went back to plan I sharpened it and used it as a knife, but after grinding it by hand for a long time, the top was a little black and could not be sharpened at all.”

"It's still a turbine blade from the 50s. The performance of this blade is not up to standard now, but it is definitely better than that."

The others all laughed and said, "That's it."

"Captain Yuan, you really have an idea."

"This idea is actually quite good. Take a discarded blade and use it as a knife. It will definitely not break, but it is a problem to grind it out. I guess you need to find a professional place."

"Going to a laboratory that makes alloy materials, or somewhere else..."

Zhao Yi did not participate in the discussion, but just listened with a smile. He also felt that the idea was very good. Looking at the leaves on the ground, he also wondered whether he should wait for the opportunity to find a few pieces to grind, and it would be best to grind them into one. The shape of a knife.

Or ask Zhang Hongtao to order a set?

Fruit knives, kitchen knives, etc., high-strength nickel alloy knives look tall.

Think Cao Cao, Cao Cao can also come!

Zhang Hongtao is here.

A guard came in to report outside, Zhao Yi immediately nodded and said, "Let him in quickly, he is an expert in alloy materials!"

After Zhang Hongtao entered the operation room, Zhao Yi immediately dragged him to the office, gave him a brief reception, and then went straight to the topic to discuss the technical issues of the turbine blades.

Zhang Hongtao is much more professional than Yuan Haitao. He has never done any research on turbine blades, and his knowledge is very professional. A nickel-iron alloy material is the result of the Institute of Metal Research, Academy of Sciences."

The Wuhang project team developed a turbojet engine, which was established in 2000. Based on the technology of the Kunlun project team, the prototype is already in production.

"One of the biggest difficulties in domestic aero-engine technology is turbine blades. The material of turbine blades is a big problem. The Metal Research Institute of the Academy of Sciences and the Aeronautical Materials Research Institute in the capital have established relevant research projects and have achieved certain results. , that is, DD5 and DD6."

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

"When I first did my research, I decided on single-crystal nickel alloys. The first-generation nickel alloys in China are also single-crystal nickel alloys. Now it's the second generation, and the performance can't keep up. We still need to continue research."

Zhao Yi asked suspiciously, "What about other plans?"

"The nickel-iron alloy is used now, because the existing nickel-iron alloy has better high temperature resistance and higher strength. DD5 and DD6 have good high temperature resistance, but the strength is slightly worse."

After Zhang Hongtao finished speaking, he explained, "Although domestic nickel-iron alloy technology is better, the main direction of research must be single crystal nickel alloy, because there are pioneers, country M, and their turbine blades are single crystal nickel alloy."

"That's it."

Zhao Yi understood.

The existing nickel-iron alloy manufacturing technology is better than the single crystal nickel alloy technology, but the technology that existed more than ten years ago has not been improved and developed until now, and it is very difficult to make further progress.

The direction of single crystal nickel alloy is different.

The world's top turbine blades use single-crystal nickel alloys, which means that there are successful ones ahead. It is very important to see hope in research and development. It can be said that there is no reference object for the research direction of nickel-iron alloys. The road to research is still If you can explore slowly by yourself, the single crystal nickel alloy already has a successful target, and if you keep going forward along the goal, you will definitely be able to continuously improve

The difference between the two is here.

That's why it appears that nickel-iron alloys are used, but the main direction of research is single crystal nickel alloys.

"Single crystal nickel does have advantages."

Zhao Yi has read a lot of information, and he still has some understanding of this aspect. "Single crystal" refers to the same orientation of the crystal lattice inside the crystal, which can also be understood as the arrangement of the atoms in the crystal in the same direction.

Such crystals have high temperature resistance and strength.

From the perspective of shaping principles, the starting point of single crystal alloys is much higher.

Zhao Yi and Zhang Hongtao discussed technical issues, and immediately said directly, "I want to improve the turbine, and hope to break through the difficulty of this alloy material. Are you interested in cooperating with me? Let's work together..."

Without waiting for Zhao Yi to finish, Zhang Hongtao nodded affirmatively, "There is no problem with cooperative research. I can represent the Metal Composite Materials Laboratory, but..."

"but?"

Zhao Yi frowned slightly.

Zhang Hongtao immediately said, "It's like this. I thought about it before I came here. There is no problem at all if we cooperate in research, but there is a problem with the application project."

"What's the problem?"

"This is a big project, a super big project." Zhang Hongtao explained, "Think about it, only the Institute of Metal Research and the Institute of Aeronautical Materials of the Academy of Sciences are doing it. If you apply in the name of the metal composite material laboratory, it is estimated that the application will not be successful. Come down, don’t say whether the higher-ups believe it or not, funding is a problem.”

Zhao Yi thought for a while and said, "How much does it cost to do this research?"

"Ten million?"

Zhang Hongtao said a number, which sounded unbelievable. He explained, "Mainly raw materials. Rare metals are very expensive, and doing research consumes a lot. Let me tell you one, rhenium is equivalent to gold and platinum. The market It is sold on the basis of 'grams', but many people know that there must be rhenium in the top turbine blade materials."

"These metal raw materials are the most expensive, and our metal composite materials laboratory is also the focus, but for this project, unless the entire laboratory applies together, otherwise... there is no hope."

Zhang Hongtao said with a sigh, and then thought of a half way, "Actually, there is a way. For example, you also have a department, which can be linked to the aviation turbine team? Anyway, you are also a special employee of the Kunlun team, so you can be regarded as a member of it."

Zhao Yi thought about it carefully and said, "I don't want others to intervene in the research, and if it's linked to the turbine group, I guess the research will go to Wucheng, right?"

"Correct."

Zhang Hongtao sighed, "But there is no way. Our laboratory cannot apply. It is best for the two laboratories to cooperate in research and development, and apply together in the name of two research institutions to have a chance."

"Just a chance?"

After listening to what Zhang Hongtao said, Zhao Yi also felt that it made sense. The research definitely needs the support from above.

He shook his head and said, "Brother Zhang, how about this, I'll think about it again, and I'll call you if I decide."

……

After Zhang Hongtao was sent away at the door, Zhao Yi was walking on the way back, thinking carefully in his mind. He wanted to study turbine blades, but he didn't want to work in Wucheng, and he didn't want other institutions or people to intervene in the research.

How to do?

Zhao Yi walked slowly towards the Faculty of Science, met Gao Yihua at the door, and asked casually, "Mr. Gao, do you know that our students have a laboratory for materials science?"

"Materials science?"

Gao Yihua thought for a while and said, "Is the material engineering in our college a new major?" He said jokingly, "Last year, an external associate professor came to lead graduate students. Does it count as a place where he leads students to do experiments?"

"...Forget it!"

"what?"

Zhao Yi nodded and said, "As long as there is one! I'll go around and ask the name, try it."

"What did you say? Try what?"

……

At eight o'clock that night, Zhao Yi called Zhang Hongtao, saying that he decided to join the "Yanhua University Metal Materials Laboratory" and cooperate with the Metal Composite Materials Laboratory of the University of Aeronautics and Astronautics to apply for "turbine blade material research and development". s project.

Zhang Hongtao was dumbfounded, "What laboratory are you talking about?"

"Metal Materials Laboratory."

"Isn't that our laboratory?"

"No." Zhao Yi corrected, "Your name is Metal Composite Materials Laboratory, we don't have the word 'composite'."

"Are you sure you're not joking?"

"I'm serious."

"However, if I apply in this way, I will probably be kicked back directly..."

"It doesn't matter, just try anyway." Zhao Yi said, "You make an application report, I will make an application report, and we jointly apply together. Let's try it. If it doesn't work, think of other ways."

"……All right."

Zhang Hongtao said helplessly, "But, don't you really consider changing your name?"

"No, I think it's pretty good, it's too troublesome to think of a name..."

Chapter 424 The Legendary Bag Laboratory

"Metal Materials Laboratory?"

"It's different without the word 'composite'? But, there is no metal material laboratory!"

Zhang Hongtao knew that the 'Metal Materials Laboratory' must have been 'fabricated' by Zhao Yi, or even if it existed, it was a small internal laboratory of Yanhua University, but he was still unwilling to check it out, and found that there was no such place at all. , Even Yanhua University's material science and engineering major is a newly established major, and there is only one associate professor in the related field, who was hired last year and has not yet brought any students.

So it is certain that the Metal Materials Laboratory of Yanhua University does not exist at all.
