Simulation: Great Power Technology

On the morning of December 18th, Ye Zhou arrived in Fengtian by high-speed train. He also arrived at the same time as several principal researchers of the Sanchi Research Institute. They will be responsible for leading the image reading and processing work in the next few months.

In order to welcome Ye Zhou, all the leaders of Liming Hangfa were in place. However, due to confidentiality requirements, a large-scale welcome party was not organized on site, but a small tea party was arranged in the general manager's office.

"Ye Gong, President Chen, let me introduce to you, I am the general manager and deputy secretary of the organization committee, Xu Qi, mainly responsible for operation, internal construction, and personnel; this is our chief accountant, or according to the popular saying, it is called CFO , Hong Lei; this is Gao Jun, the chief engineer, who mainly focuses on production, construction, and research and development."

"After that, the three of us will directly interface with you. No matter what difficulties or requirements you have, you can put forward them immediately, and we will implement them unconditionally."

Ye Zhou nodded, shook hands with the three of them one by one, and replied:

"Boss Chen is mainly responsible for the overall planning. I am mainly responsible for technology. In addition, I may participate in some personnel arrangements and job assignments. We can discuss specific matters later. Today, I mainly want to ask if you have any concerns about this project. Complete understanding?"

"Yes! Ye Gong, I have already read all the technical documents, and have marked the technical difficulties. From the current situation, it is difficult to complete the production within 3 months of the project reservation, but it is not very difficult."

Hearing Ye Zhou's question, the chief engineer on the opposite side hurriedly answered.

He is an expert in the field of domestic aviation and has decades of experience in the industry. Whether in terms of qualifications or technology, he is actually much stronger than the current Ye Zhou, but in front of Ye Zhou, he did not perform. out of any arrogance.

Scientific research, especially in the field of aviation development, is the big brother if you have something in your hand.

Although he has risen from a technical position to an administrative position, his respect for technicians in his bones has not changed.

"Tell me about the technical difficulties?"

"The biggest problem I have seen so far is the creep problem. Although this drawing has the blade material ratio and the metal ratio of each part, but in the actual processing process, due to temperature control, impurities and other problems, we It's not 100% replicating the leaf material distribution."

"For example, according to the requirements on the drawings, we have to use a total of 9 different metal elements to make the blade, in which the melting point of iron is 1500 degrees and nickel is 1400 degrees. We need to control the composition of nickel to balance the creep of the blade. scope."

"This work requires constant testing, and it's likely that just small differences can lead to huge problems in the final engine."

"Moreover......"

Hearing Ye Zhou asking about technology-related questions, Gao Jun's nature suddenly came up. He gushed about the various difficulties in this document, but what surprised Ye Zhou was that his attitude towards these difficulties did not change. Not fear, but...excitement.

Presumably seeing it as a challenge.

Several other people in the office listened with great interest at first, but as the topic went deeper, they gradually couldn't keep up. When they talked about the arrangement function of the heat dissipation hole of the hollow blade and the thermal barrier coating, even the simulation had been accepted. Ye Zhou, who was instilled by the device, started to have a headache.

This thing has gone beyond the basic knowledge of aero-engines and has begun to enter the field of materials science and thermodynamics.

"...So, we have the punching function here, and we have also experienced the test of the previous engines. The heat dissipation efficiency is even stronger than that of other foreign engines, but the problem lies in the thermal barrier coating. This is not a simple thermal insulation film, but a complete set of tbc thermal insulation system, we do not have a good tbc base material, but there is still some research on the anti-oxidation connection layer material."

"If we want to do it, we probably need to import these materials from abroad, but we just don't know whether they can provide it or not. This is a big problem, but to be honest, the resources are so abundant this time, the big deal is that we will start tbc from scratch! "

"Anyway, tbc is going to be done sooner or later. We do it all at once, and it will save trouble in the future..."

"Hey, Lao Gao, Lao Gao!"

Sitting beside Xu Qi heard what he said and hurriedly interrupted.

His expression was a little embarrassed. He originally organized this tea party to express his resolve to Ye Zhou, but Ye Zhou didn't expect to play cards according to the routine, so he first asked about the difficulties when he came up.

It is no problem to say that it is difficult. After all, reasonable management of the expectations of leaders is also a very important thing in the workplace.

However, it is necessary to choose the right time to talk about difficulties. It is a bit too inappropriate to meet just now.

Gao Jun, who was still immersed in excitement, reacted at once, he also smiled awkwardly, and said apologetically to Ye Zhou:

"Ye Gong, I'm really sorry for saying too much. But don't worry, these difficulties are indeed a little more, but in general, they should all be overcome..."

"Should? What should it mean?"

Ye Zhou interrupted him and asked back with a frown.

"What I should say is that we have a feasible plan, but the implementation effect of the plan may not meet expectations. For example, the tbc system I just mentioned, in fact, we can add zro2 and y2o3 to the metal base according to the composition requirements in the document. Alternative solutions, but I doubt that this coating can achieve the best results, because the manufacture of tbc is also a university question..."

After listening to Gao Jun's words, Ye Zhou nodded slightly.

Gu Ling He originally wanted to blow up the other party to see how much preparation he had done for this project. If he is hesitant or outspoken in the face of his own problems, then Ye Zhou's expectations for this project are about to be greatly reduced.

Fortunately, Gao Jun's answer satisfied him.

If he can speak out the alternatives on the spot, it proves that he has really put in the effort to study it. Even if there is no way to clarify all the problems in this extremely short period of time, at least he has a very positive attitude.

"I understand, I will find a way to solve this problem. Sanchi laboratory is just making a kind of thermal insulation material, and it is no longer willing to industrialize it. It should be used as a tbc substrate."

"Sanchi laboratory? Ye Gong, your own laboratory? Are you working on insulation materials?"

Gao Jun's eyes suddenly widened, and he looked at Ye Zhou in disbelief.

He knows too much how much resources are needed to develop a new material. From formula design to laboratory preparation, he doesn't know how many people's efforts are required.

To achieve stable manufacturing, it is a long story.

Now, the young man actually says that his laboratory has developed the thermal insulation material and it will be ready for mass production soon.

Sanchi Research Institute...how does he remember, this research institute seems to have just been listed not long ago, right?

Ye Zhou on the opposite side nodded and replied:

"Yes, it's been a while. The material mainly uses the principle of carbon foam. I will give you the contact person of the institute, and you can coordinate the cooperation when the time comes."

"The principle of carbon foam....that can indeed be used as a base material for tbc, well, Ye Gong, I will contact you in a while!"

Gao Jun said excitedly.

The two continued to chat along the topic of materials. Ye Zhou mentioned the anti-perovskite structure negative thermal expansion material, which surprised Gao Jun even more.

Could it be that this time it is more than just imitation?

Judging from the current engine design documents, all the high temperature resistant materials required for the blades can be produced in China. At this time, a new material is proposed, and it is a negative thermal expansion material that only stays in the laboratory verification process. The answer is probably only One.

He also has to warm up the engine.

In other words, the final thrust of this engine is probably more than the 70 tons marked on the drawings.

This young man's ambition was even greater than he thought.

At the end of the chat, Ye Zhou took the initiative to stop talking and said:

"What I just said is actually just an idea for the future. The main thing we have to do this time is to build the engine as it is. After it is built, we can continue to think about optimization.. …”

"Understood, Ye Gong!"

Hearing this, Gao Jun breathed a sigh of relief.

Fortunately, this is the case. Otherwise, if he is really asked to optimize the design, he will not be able to complete the task within the project time.

The lengthy technical topic was finally over, and everyone in the office began to coordinate work arrangements. The main chat was Chen Hao. It wasn't until after twelve o'clock that several people finally ended the topic and prepared to go out for dinner.

But just as they packed up and walked downstairs together, Xu Qi's secretary suddenly came over.

"Mr. Xu, there is something wrong."

Xu Qi glanced at Ye Zhou beside him, frowned and said:

"If something happens, report it directly."

The secretary nodded, handed the document in his hand to Xu Qi, and said:

"Xiao He applied for resignation..."
