Chapter 424 Isn’t that Our Laboratory?

Power Engineering Laboratory.

Zhao Yi was stuck by the problem of the alloy material of the turbine blades, but he did not stop improving the engine. He put aside the problem of turbine blades and continued to discuss the structure of the turbine with Yuan Haitao and Zhou Qing.

Structure is design.

The material of turbine blades is hard currency and the most basic issue, which is directly related to the efficiency of the engine. However, the ‘soft power’ of the design is also very important and directly affects the performance of the engine.

The most important component inside a turbine is the blades. There are also other auxiliary devices such as gears and rotating shafts to drive the blades to rotate. The design of the blades and other components must be coordinated to make the turbine run.

The design of these complex components is a very important issue.

The R&D team of the Kunlun engine came up with several plans, and finally selected one with a slightly better argument. But in fact, because there was no prototype to refer to, the argument for the composition of each component was very complicated, and there was not enough theoretical support. Under such circumstances, the final plan they come up with may not necessarily be better than the eliminated plan.

So the most important thing is 'theoretical issue'.

Zhao Yi has no way to directly get a perfect plan, because the data involved in formulating the plan fluctuates too much, resulting in a huge amount of calculations. Even the top supercomputer cannot come up with the so-called 'perfect plan' .

When I found that I couldn't come up with a complete set of perfect design solutions, I simply decided to improve it bit by bit. For example, after accepting the turbine blade design, I expanded to the connected components next to it, and slowly improved it bit by bit until the last one. part.

This approach may not necessarily result in the most perfect solution, but the resulting solution will definitely be more effective than the existing design.

Zhao Yi talked to 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 them 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 truly seeing the structure inside can we have a better understanding.”

Yuan Haitao and Zhou Qing looked at each other and could only say forcefully, "Tear it down! Tear it down!"

"Take it out!"

Both of them couldn't understand it.

The turbine and the combustion chamber are connected together, but they are two components, and they are tested separately. Disassembly is still acceptable. The turbine is one component, just like a car engine, and the combustion part has been disassembled. What’s the point of disassembling the pushing and rotating parts if they fall off?

Check the parts composition?

But it’s all on the engine design drawings…

Zhao Yi didn't care what the two people thought. He just wanted to take it apart and have a look so that he could get more conditions to improve the design plan. Because with the new design plan, the prototype has completed its mission. Is it meaningful in terms of assembly? Big.

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

It's like getting an unknown mechanical toy. If you want to know what's inside, just take it apart and take a look. The process is very interesting. Every time you remove a part, you take it in front of your eyes and look at it carefully.

The more Zhao Yi dismantled it, the more interesting it became. Later, he simply asked someone to teach him how to dismantle it, and he did the disassembly work himself. When he removed the rotating shaft inside, he felt a novel sense of accomplishment.

"really interesting……"

"So, men still want to do mechanical things from time to time. No wonder I read a lot of news about so-and-so making rockets, so-and-so making machines, etc. It doesn't matter whether the things made are meaningful or not, the key is the process... …Well, it’s interesting.”

Others don't see it that way.

Yuan Haitao watched Zhao Yi actively participate in the disassembly work, and even took away other people's work. He couldn't help but muttered, "Academician Zhao decided to dismantle the turbine, isn't it just for... fun?"

Another engineer in his forties, Xue Fengge, happened to come over and heard Yuan Haitao's words. He immediately shook his head and said, "Captain Yuan, I see, Academician Zhao is very serious. He also asked what the use of each component is to understand the details. Principle. He has always been serious. I see..."

Xue Fengge listened for a while and affirmed, "He wants to design a turbine himself and build one."

"ah?"

Yuan Haitao really didn't expect it.

Although he had been discussing turbine issues with Zhao Yi, he just thought that he was discussing the design plan. If he found any problems, he would record them and submit them.

Now you design and make your own plans?

is it possible?

Kunlun Engine has a R&D team designing turbines. The turbine R&D team initially had seven or eight people. Subsequent adjustments made it into a team of more than a dozen people, and they have been working for more than ten years.

After the Kunlun Group successfully produced the first prototype, the turbine R&D group was reorganized and settled in the R&D base in Wucheng, and directly became a department named Wucheng Aviation Turbine Unit.

The job of this R&D team is to develop aviation turbines. Of course, their research and development is not only about design, but also about turbine materials. However, there has been no progress in the alloy material part. But in any case, the result of their work as a team is to develop turbines. Research.

Now……

"Academician Zhao alone, even if we are included, there are only four people, how can he possibly design a turbine!"

Yuan Haitao felt like he heard a joke.

Xue Fengge said, "Zhou Qing doesn't know much about turbines. I'm not good at research and development, and neither are you, Captain Yuan..." He paused for a moment and continued, "Ahem, Captain Yuan is the only one who knows a little bit. You and I Academician Zhao, two people."

"Anyway, I think Academician Zhao has an idea, and it's Academician Zhao!"

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

"Right."

The job they were assigned 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 heavy and there are many parts, so placing them separately is very cumbersome.

At around one o'clock in the afternoon, Zhao Yi and two workers removed the most important turbine blades one by one. There are sixty turbine blades inside the turbine. Each blade is made very finely. If you take it out and polish it, it seems that it can Become a sharp knife.

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

"It's very intense."

Yuan Haitao suddenly said something, and everyone else looked over. He explained a little embarrassedly, "A few years ago, there was a scrapped fighter jet made in China in the 1950s. I took off a blade and went back I planned to sharpen it and use it as a knife, but after sharpening it for a long time, it became a little black and I couldn’t sharpen it at all.”

"This is a turbine blade from the 1950s. The performance of this blade is not up to standard now, but it is definitely better than that."

After hearing this, everyone else laughed and said, "That's it."

"Captain Yuan, you really have some ideas."

"This idea is actually quite good. You can use the discarded blades as knives. It will definitely be useful, but grinding them out is a problem. I guess you need to find a professional place."

"Go 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 thought the idea was very good. Looking at the leaves on the ground, he also thought about waiting for a chance to find a few and grind them. It would be better to grind them into one. The shape of a knife.

How about asking Zhang Hongtao to customize a set?

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

If you want Cao Cao, Cao Cao can get there!

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 pulled him into the office, briefly entertained him, and then went straight to the topic to discuss the technical issues of turbine blades.

Zhang Hongtao is much more professional than Yuan Haitao. He has never done research on turbine blades, and his knowledge is very professional. "As far as I know, the turbine blades used in our domestically made aeroengines, namely Kunlun and Wuxing, should be A nickel-iron alloy material, it is the result of the original Institute of Metal Research of the Academy of Sciences.”

The Wuxing project team is developing a turbojet engine. It was a project established after 2000. It is based on the technology of the Kunlun project team and the prototype is already in production.

"One of the biggest difficulties in domestic aero-engine technology now is turbine blades. Turbine blade materials are a big problem. The Institute of Metals of the Academy of Sciences and the Aviation Materials Research Institute of the Capital have related research and have achieved certain results. , namely DD5 and DD6."

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

"When we first started doing research, the determined direction was single crystal nickel alloys. The first generation of nickel alloys in China were also single crystal nickel alloys. Now it is the second generation, and its performance cannot keep up, so we still need to continue research."

Zhao Yi asked doubtfully, "What are the other plans?"

"Currently, nickel-iron alloys are used, because the existing nickel-iron alloys have better high-temperature resistance and higher strength. DD5 and DD6 have good high-temperature resistance, but their 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, their turbine blades are single crystal nickel alloy."

"That's it."

Zhao Yi understood.

The existing nickel-iron alloy manufacturing technology is better than single crystal nickel alloy technology, but the technology that existed more than ten years ago has not been improved or developed until now. 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 there are winners 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, and there is still room for research. If you can slowly explore by yourself, there are already successful targets for single crystal nickel alloys. If you keep moving forward with your goals, you will definitely be able to continuously improve.

The difference between the two is here.

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

"Single crystal nickel does have advantages."

Zhao Yi has read a lot of information and has some understanding of this aspect. "Single crystal" refers to the same lattice orientation within the crystal, which can also be understood as the completely consistent arrangement of the internal atoms.

Such crystals will have higher 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 then said directly, "I want to improve the turbine and hope to overcome the difficulties of this alloy material. Are you interested in cooperating with me? Let's work together..."

Zhang Hongtao nodded affirmatively before Zhao Yi finished speaking, "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, "That's right. I thought about it before I came here. There is no problem at all if we collaborate on research, but there is a problem with the project application."

"What is 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 working on it. If you apply in the name of the Metal Composite Materials Laboratory, you probably won't be able to apply. Come down, don’t tell me whether you believe it or not, funding is a problem.”

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

"Tens of millions, right?"

Zhang Hongtao opened his mouth and mentioned a number, which sounded a bit incredible. He explained, "Mainly raw materials. Rare metals are very expensive, and research losses are very large. Let me tell you one thing, rhenium is equivalent to gold and platinum. The market They are all sold on the basis of 'gram', but many people know that the top turbine blade materials must contain rhenium."

"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, there is... no hope."

Zhang Hongtao sighed and then thought of a way, "Actually, there is a way. For example, you also have a department that can be attached to the aviation turbine group? Anyway, you are also a special employee of the Kunlun group, so you can be considered a member of it."

Zhao Yi thought about it carefully and said, "I don't want others to get involved in the research. Besides, if I hang on to the turbine group, I guess the research will have to go to Wucheng, right?"

"right."

Zhang Hongtao sighed, "But there is no way. Our laboratory cannot apply. It is best for 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?"

Zhao Yi also felt that what Zhang Hongtao said made sense. Research definitely needed support from above. It was best to apply for the project, otherwise even if he spent his own money, he would not be able to get the materials for research.

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

…

After seeing off Zhang Hongtao at the door, Zhao Yi was walking back, thinking carefully in his mind. He wanted to study turbine blades, but he didn't want to go to work in Wucheng, and he didn't want other institutions or other people to get involved in the research.

what to do?

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

"Materials science?"

Gao Yihua thought for a while and asked, "Is materials engineering a new major in our college?" He said in a joking tone, "Last year, an external associate professor came to teach graduate students. Does the place where he leads students do experiments count?"

"...Forget it!"

"ah?"

Zhao Yi nodded and said, "Yes, that's fine! I'll go around and ask for names and give it a try."

"What did you say? What to try?"

…

At eight o'clock that night, Zhao Yi called Zhang Hongtao and told him that he had decided to join the "Metal Materials Laboratory of Yanhua University" and cooperate with the Metal Composite Materials Laboratory of the University of Aeronautics and Astronautics to apply for "Turbine Blade Materials Research and Development" s project.

Zhang Hongtao was stunned. "What laboratory did you say?"

"Metal Materials Laboratory."

"Isn't that our laboratory?"

"No." Zhao Yi corrected, "You call it the Metal Composite Materials Laboratory. We don't have the word 'composite'."

"Are you sure you're not kidding?"

"I'm serious."

"But if I apply like this, I will probably be kicked back..."

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

"……All right."

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

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