Rule department scholar

It was successfully developed in the past few years, but due to the long time span, it still has not kept up with the top international level, and performance and failure are big problems. If you want to popularize three-generation and three-and-a-half-generation fighters, you must solve these two big problems.

Zhang Gangchuan said frankly to the expert group, "We are confident that if we continue to do this, there will be a perfect day, it's just a matter of time..."

"So this time, when you come here, I specifically mentioned it, hoping that someone can help us with our work..."

He spoke very sincerely.

The members of the expert team can also feel Zhang Gangchuan's sincerity, but the turbofan series engine has been developed for more than [-] years, and the internal structure is very complicated. There are academicians who specialize in the direction of power, but they can only understand the design and want to propose a perfect solution. Opinions are also hard.

They are really powerless.

So is Zhao Yi.

Zhang Gangchuan just gave a brief introduction to the parameters of the Kunlun engine, and took the expert team to visit a built engine and a fighter plane equipped with the Kunlun engine.

These are not enough to provide enough conditions. In addition, the structure of the engine is very complicated. If he wants to use the system ability to study it, he will not be able to use it at all.

After the expert group visited, they were entertained to have a meal in the lobby.

Zhang Gangchuan specifically found Zhao Yi, went to the office with him, and said sincerely, "Academician Zhao, you have also seen the problems we are researching, and I would like to invite you to be the 'special expert' of the Kunlun engine R&D team."

Zhao Yi hesitated.

Zhang Gangchuan continued, "I also know, Academician Zhao, you have a lot of research and are very busy. You don't need to do anything special when you come to be our specially-appointed expert. It's just that when you have questions, you can take a look if you are free. If you can't solve it, it doesn't matter."

"Actually, this time, I mainly want to invite you. The others..." He shook his head and said, "Even if you are an academician of power engineering, no matter how top-notch your research is, it won't be of much help."

What Zhang Gangchuan said was very sincere, and his posture was low enough that Zhao Yi didn't even know how to refuse.

You don't have to do anything to be a specially-appointed expert, just get a "research and development team expert subsidy" for nothing, even if you participate in research and development, you are just a "consultant".

Such a good thing...

Zhao Yi thought about it carefully. He didn't care about any subsidies, and he wouldn't agree to it just because the other party lowered his attitude. Instead, he thought about related research issues.

Now that the Kunlun engine has been successfully developed, the follow-up is to improve the performance of the engine and reduce faults on the basis of the same structure. It sounds very simple. As long as there is enough understanding, the "Law of Supervision" will directly solve it?

Zhao Yi thought about it and said, "I have no objection to being a specially-appointed professor, but the premise is that my work must be meaningful, not just doing calculations..."

He was a little depressed as he spoke.

Zhang Gangchuan understood at once. He and Ying Shaowen are very familiar with each other. Research on aero-engines and aircraft-carrier engines are both in the same field of research. There must be communication with each other. He remembered Ying Shaowen's praise of Zhao Yi's computing ability , Said that one person tops them as a team.

Before Zhang Gangchuan didn't think there was anything wrong, when he heard Zhao Yi's words, he suddenly realized, "Ying Shaowen, this guy actually regards Zhao Yi as a calculation tool? No wonder Zhao Yi directly rejected him."

"Ha ha……"

Zhang Gangchuan wanted to laugh a little, but he still held back and asked, "The work you said is meaningful, do you mean?"

"I need to see the detailed information of Kunlun, including the structure, design drawings, technology involved, and even the materials of each component, control system, etc., everything."

Zhao Yi said seriously, "In this way, I can know how to do perfection, instead of doing calculations and being a consultant." He added calmly, "I am not an expert in engines, and my knowledge of this aspect is limited. Unqualified."

Zhang Gangchuan took a deep breath and looked at Zhao Yi in surprise.

What Zhao Yi said involves the issue of 'confidentiality', and only researchers who are really in the R&D team and participate in the whole process of R&D are eligible to view so much information.

Kunlun R&D spans more than 20 years, and those who are still working in the R&D group, many of them join in the middle, and the work only involves a part of the content, for example, the research on the control system will not use the information of the fan blades, just need to know The parameters are fine.

Now that Zhao Yi said he needed so much information, Zhang Gangchuan couldn't make a decision right away.

Zhao Yi continued, "I don't want to take it all at once, I need to read a part and a part, and I can take it slowly. But my needs for information must be met, so that I can play a role."

Zhang Gangchuan took another deep breath, thought for a long time in silence, finally gritted his teeth and nodded, "Okay!"

Chapter 4 Why is Academician Zhao Da here?

It took a lot of effort to say the word "good" by Zhang Gangchuan, and he took a long breath after speaking, as if he had made a major decision.

The main one involved is the issue of confidentiality.

The Kunlun engine is the only turbofan engine independently developed and built in China. It is also a military engine. It is impossible for ordinary people to take a look at it. The related research and development information of the engine is absolutely confidential. If it is someone else , including academicians in the expert group, let alone want to view all the information, even if it is a certain part of the information, they have to apply to their superiors.

Zhao Yi is different.

Zhang Gangchuan also made some measurements. Zhao Yi is the top scholar and the top scientific research genius. His personal achievements are so high that others can only look up to him. The influence and value created completely surpass the existence of the Kunlun engine.

If there is a political leak on Zhao Yi, the leak of Kunlun engine information is not important at all, and the higher-ups may care more about Zhao Yi himself.

Zhang Gangchuan thought about it carefully, and felt that confidentiality was not a problem, so he gritted his teeth and agreed.

The reason why it is so difficult to agree is that the research on the Kunlun engine has taken more than 20 years to establish the research project of the Kunlun engine, and the repair and improvement work has also been carried out for several years. It has been more than 30 years. It is conceivable how much content there will be and how difficult it is.

Now every line on the engine can be said to be the painstaking effort of the research team.

When the Kunlun engine project was established, Zhang Gangchuan was just an ordinary researcher involved in the work. Later, the engine project was shelved twice, and the project design director went for three waves. Zhang Gangchuan was promoted to project designer and person in charge. The best years of my life at the age of 20, I can say that I have dedicated my whole life to the design and construction of Kunlun engines.

In the eyes of the outside world, the construction of the Kunlun engine can be regarded as a success, not to mention the performance of the engine can not keep up, more temporary failures and other issues, at least it also made up for the gap in the domestic independent research and development of turbofan engines, with the development experience of the Kunlun engine, Data, and then go to develop other aero engines, you can also find a group of experienced researchers, and the efficiency of research and development will definitely increase a lot.

However, Zhang Gangchuan didn't think so.

Decades of efforts have been devoted to the Kunlun engine, hoping to develop an aero engine that can catch up with the international high-end level. After the development results, the performance cannot keep up. His only goal is to improve the Kunlun engine so that it can be loaded on a large area to a fighter in service.

Only in this way can I feel that the pursuit of a lifetime and the efforts of a lifetime have not been in vain.

"Academician Zhao is a top mathematician. It is said that he knows a little about everything and can give good advice." Zhang Gangchuan heard a lot of news and thought expectantly, "I hope Academician Zhao can really help and speed up the improvement of the engine. Speed ​​up!"

Zhang Gangchuan thought with some expectation.

After Zhao Yi and Zhang Gangchuan negotiated the conditions, the atmosphere became a lot more relaxed. He asked some questions about the parameters of the engine, and also learned about the current situation of domestic fighter jets.

The research and development direction in China is advanced fourth-generation fighters and fifth-generation fighters, but the fighters in service are mainly third-generation fighters, and the number of second-and-a-half to three-and-a-half-generation fighters is the largest.

"The Kunlun engine will be perfected within five years, and it will be usable. It can be used on three-and-a-half-generation fighter jets, and it may be planned to load hundreds or thousands of them."

Zhang Gangchuan said seriously, "If it takes longer, you may consider developing a next-generation engine."

If the delay is longer and cannot keep up with the speed of replacing fighter jets in China, the engine will definitely not be used, and we can only start the next research and development project. It cannot be said that it will be used for another 20 or 30 years, but within ten years , it is definitely impossible to complete.

The younger ones in the R&D team can still work in the new R&D team. Zhang Gangchuan is at best a consultant and can almost consider retirement.

Zhang Gangchuan looked a little depressed when he said that, the project that he had devoted his whole life to would not be used at all after completion, and it was indeed a failure for him personally.

Zhao Yi is very sympathetic to Zhang Gangchuan, but he agreed to be a "specially hired expert", not because of any sympathy, but because he is very interested. The development of engines is indeed very attractive, especially aero engines, and the results of the development may be loaded into many fighters In fact, the aero engine is the core of the fighter.

If the main fighters in domestic service, or the highest-tech top fighters, are loaded with engines designed by themselves, it feels very fulfilling to think about it.

Zhao Yi couldn't wait any longer.

……

Distinguished experts are external experts hired by the R&D team, and can also be understood as "consultants". Because of the major confidentiality issues involved, not every expert can be a "consultant". OK.

Because all the scholars involved are well-known and well-known, the employment also needs the approval of the superiors, and the agreement is not so important.

Zhao Yi still signed a non-disclosure agreement. The work agreement of "specially hired experts" only has a few short clauses. It seems very simple, because it is all funded by superiors. After the work results are reported, there is no need to go through the R&D team. 'Salary' is called directly.

On the last day, Zhao Yi was still with the expert group, went to the surrounding scenic spots, played leisurely for a day, and was sent back to Yanhua University by the commissioner the next day.

Zhao Yi was absent for more than a week, and accumulated a lot of work. He went to the Faculty of Science, the Institute of Biomedical Sciences, and visited He Mingcheng's home, and then decided to hold a public class on particle boundary theory. It's a little easier.

at the same time.

Aeronautical R&D Center, Kunlun Engine R&D Group.

Zhang Gangchuan was sitting in front of his desk. There were two thick stacks of documents and materials on the desk. He carefully looked at them one by one, and kept taking notes with a pen, thinking carefully about the selection.

Zhao Yi asked for all the information on the empty engine, and sorting out the information is a complicated matter, because many important materials involve confidentiality issues, and Zhang Gangchuan can only sort them out by himself.

In addition, he also considered the organization of sending materials.

It is impossible to send all these materials in one go, and only part of them can be sent at the beginning. He knows that Zhao Yi has little knowledge about engine development, so he needs to send the frame content first, so that Zhao Yi can have a general understanding of the Kunlun engine.

Among them, the power and the output fan blade are the most important components of the engine.

Next comes the design framework.

The design framework is based on the power and output fan blades, including internal shafts, external circuits, and control systems, etc., are based on the two central parts, and the design is extended. The design information of each part , can have a thick stack of documents.

Because the original design was in the 70s, many file contents were not uploaded to the computer, and the finishing work became very complicated.

While looking at the content of the document, Zhang Gangchuan couldn't help but recall the scene at that time, and recorded the key content. Some designs have been adjusted, but he still recorded the original design plan.

At this moment, there was a knock on the office door.

Ying Shaowen was standing at the door, looked over with a smile on his face, and said hello, "Old Zhang, busy!"

"Collect the information!"

Zhang Gangchuan explained with a smile, put down the work at hand, and made tea for Ying Shaowen again.

Ying Shaowen sat on the chair and asked amusedly, "Did you work so hard today? The expert team just left. You are not like this usually, and what can you do? It is impossible for you to have a breakthrough in the past few days." Bar?"

Zhang Gangchuan is definitely not a lazy person. He is still very diligent in his work, but it is not enough to do research. The Kunlun engine needs to be improved and repaired. Only with good suggestions can we continue. Otherwise, we don’t know where to start if we want to change the plan. .

This is not using programming software. Background debugging will prompt errors, and there will not be a large number of user feedback BUG. If you want to find problems, you have to research them yourself.

Ying Shaowen looked at Zhang Gangchuan with a strange look in his eyes. He thought that Zhang Gangchuan became diligent because he was "stimulated".

What stimulus?

For example, he kept inquiring about Zhao Yi, and wanted to invite Zhao Yi to join the Kunlun R&D team, but...failed?

"It must have failed!"

"Looking at Zhao Yi's attitude, he doesn't even want to join any R&D team, no matter how invited he is!"

"The invitation failed, and I was denied face. Lao Zhang felt depressed and made up his mind to complete it by himself..."

"However, this kind of thing is all about 3 minutes of enthusiasm. It's useless to study this thing in a hurry and work hard. You still have to find the problem before you can find a way to solve it."

Ying Shaowen thought amusedly, and simply persuaded him directly, "Old Zhang, don't pay too much attention to it."

"Academician Zhao, what kind of person is that? The world's number one mathematician who also has research in physics and medicine. It's impossible for that kind of person to join our research and development team. The level is different."

"Don't say it's your group. Our group and Ma Mingwei's group are the same. Academician Zhao was invited by Ma Mingwei. He still blames me. What does this have to do with me?"

"I really want to invite Zhao Yi, he really..." Ying Shaowen thought for a long time, and said a word, "Genius, super genius! He is a humanoid self-propelled supercomputer, we are a team, a dozen people , and the combined computing power cannot keep up with half of his."

Zhang Gangchuan listened silently, and suddenly said, "What did you just say? Why do people walk on their own?"

"Humanoid self-propelled supercomputer?" Ying Shao Wendao, "Really, I told you last time, Zhao Yi's computing power, really, I can't imagine anyway, very responsible power calculation, he can do it The result will come out directly, and you say it’s amazing. That’s why I want to invite him..."

"Oh~~~"

Zhang Gangchuan interrupted and elongated the tone, he suddenly said, "I'll just say it, how could Zhao Yi say that if you don't do simple calculation work, it's you..."

"What's wrong with me?" Ying Shaowen asked doubtfully.

"You just want Zhao Yi to do the calculations for you."

"Isn't he a mathematician?"

"Mathematicians do calculations?" Zhang Gangchuan opened his mouth exaggeratedly, "This is the reason why your invitation failed. In fact, I can see that Zhao Yi is still very interested in engine research and development."

"Really? But... so what?"

"He agreed to serve as our special expert." Zhang Gangchuan finally smiled, "Because I really regard him as an expert and consultant, and I hope he can give us advice on engine design and architecture, rather than just doing calculations. ?"

"Are you invited?"

"Yes." Zhang Gangchuan replied with a smile.

Ying Shaowen was very upset when he heard it. He said depressedly, "If you don't do calculations, what's the use? He doesn't understand engines, so what advice can he give? You expect a mathematician to be an engineer? To be an engine?" He said funny shaking his head.

Zhang Gangchuan pursed his lips, "I believe him."

Ying Shaowen shrugged nonchalantly, and said, "Perhaps, you are right. Even if he can't provide help, he participated in the Kunlun project and may be your successor."

……

Zhang Gangchuan's work efficiency is very high. It took only three days to sort out a part of the materials, and asked special personnel to send them to Zhao Yi himself.

This part of the information includes the original design plan, and some basic structural issues. The confidentiality is relatively poor, but it is not afraid of spreading it out.

After Zhao Yi got the information, when he studied it carefully, he found a somewhat embarrassing problem--

He was a little confused.

The engine seems to be just a piece of machinery and does not involve complicated theoretical support, but machinery, automation, and dynamics all have their own majors, and there are still a lot of knowledge involved.

Zhao Yi simply went to the library to check some basic books and learn related professional knowledge. Compared with the difficult mathematics and physics, the knowledge of engineering is relatively much simpler, and he also has very advanced mathematics. , Computer foundation, just read some professional books a little.

He went to the library to find a large stack of books related to machinery, automation, and power engineering, and then piled them on the desk in the office of the Faculty of Science, and sat idly on a chair to read them.

Hu Zhibin came over to talk to Zhao Yi about the open class of particle boundary theory, and found that Zhao Yi was watching...

"Gas Turbine and Gas?"
