Great Power Technology

On the morning of December 18, Ye Zhou arrived in Fengtian via the high-speed rail. Also arriving at the same time were several key researchers from the Sanchi Research Institute, who 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 Aviation were in place. However, due to confidentiality requirements, no large-scale welcome party was organized on site. Only a small tea party was arranged in the general manager's office.

"Ye Gong, Mr. Chen, let me introduce to you. I am the general manager and deputy secretary of the organization committee, Xu Qi. I am mainly responsible for operations, internal construction, and personnel. This is our chief accountant, or according to popular sayings, called CFO. , Hong Lei; this is Chief Engineer Gao Jun, who is mainly responsible for 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 them forward 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 coordinating matters. I am mainly responsible for technology. In addition, I may participate in some personnel arrangements and job arrangements. We can discuss specific matters later. Today I mainly want to ask if you have any questions about this project. Complete understanding?”

"Yes! Ye Gong, I have read through all the technical documents and have marked the technical difficulties. Judging from the current situation, it is difficult to complete production within the three months scheduled for the project, but it is not great."

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

He is an expert in the field of domestic aviation development and has decades of experience in the industry. In terms of qualifications and technology, he is actually much better than the current Ye Zhou. However, he did not perform well in front of Ye Zhou. Show no arrogance.

In scientific research, especially in the field of aerospace engineering, if you have something in hand, you are the big brother.

Although he has been promoted from a technical position to an administrative position, his deep respect for technical personnel has not changed.

"Tell me about the technical difficulties?"

"The biggest problem we see so far is creep. Although this drawing contains the blade material ratio and the metal ratio of each part, during the actual processing process, due to issues such as temperature control, impurities, etc., we It cannot 100% replicate the blade material distribution."

"For example, according to the requirements on the drawing, we need to use a total of 9 different metal elements to make the blades. The melting point of iron is 1500 degrees and the melting point of nickel is 1400 degrees. We need to control the composition of nickel to evenly adjust the creep of the blades. scope."

"This work requires constant testing, and it is possible that just a small difference can lead to huge problems in the final engine."

"Moreover."

Hearing Ye Zhou ask technical questions, Gao Jun's temper suddenly rose. He talked endlessly about the various difficulties in this document, but what surprised Ye Zhou was that his attitude towards these difficulties was not the same. Not fear, but excitement.

Probably taking it as a challenge.

Several other people in the office listened with interest at first, but as the topic progressed further, they gradually couldn't keep up. By the time they talked about the hollow blade cooling hole arrangement function and thermal barrier coating, Lian had already undergone simulation. Ye Zhou, who was instilled with the device, began to have a headache.

This stuff has gone beyond basic aero-engine knowledge and begun to enter the fields of materials science and thermodynamics.

"So, we have the punching function here, and it has been tested by previous engines. The heat dissipation efficiency is even better than other foreign engines. But the problem lies in the thermal barrier coating. This is not a simple Thermal insulation film is a complete set of TBC thermal insulation system. We do not have a good TBC base material, but we have done some research on anti-oxidation connecting layer materials."

"If we want to do it, we probably need to import these materials from abroad, but we just don't know if they can provide them. This is a big problem, but to be honest, the resources this time are so sufficient, at worst we will start TBC from scratch! "

"Anyway, TBC will be launched sooner or later. If we do it at once, it will save trouble in the future."

"Hey, Lao Gao, Lao Gao!"

Xu Qi, who was sitting nearby, heard what he said and quickly interrupted.

His expression was a little embarrassed. He had originally organized this tea party to express his determination to Ye Zhou, but he didn't expect that Ye Zhou didn't follow the routine at all and asked about the difficulties first.

It’s okay to say it’s difficult. After all, managing leaders’ expectations reasonably is also a very important thing in the workplace.

However, it is difficult to say that you have to choose the right time. It is really inappropriate to have just met.

Gao Jun, who was still immersed in excitement, reacted immediately. He smiled awkwardly, and then said apologetically to Ye Zhou:

"Ye Gong, I'm really sorry for saying too much all at once. But don't worry, these difficulties are indeed a bit more, but generally speaking they can be overcome."

"Should? What does should mean?"

Ye Zhou interrupted him and asked with a frown.

"What I'm saying is that we have feasible plans, but the implementation effect of the plan may not meet expectations. For example, the TBC system I just mentioned, in fact, we can use a metal base plus ZRO2 and Y2O3 according to the composition requirements in the document Alternative solution, but I suspect that this coating cannot achieve the best results, because the manufacturing of TBC is also a big problem."

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

He originally wanted to blow up the other party to see how much preparation he had made for this project. If he was hesitant in facing his own problems or was too bold to speak out, then what was Ye Zhou's expectation for this project? It will be greatly reduced.

Fortunately, Gao Jun's answer satisfied him.

Being able to tell the alternative on the spot proves that he has really put in the effort to study it. Even if he cannot explain all the problems clearly in this very short period of time, at least his attitude is very positive.

"I understand. I will find a way to solve this problem. Sanchi Laboratory happens to be making a kind of thermal insulation material. It is no longer ready for industrial production. It should be able to 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 knew very well how many resources were needed to develop a new material. From formula design to laboratory preparation, he didn't know how many people had to work hard.

To achieve stable manufacturing, it is another long story.

Now, this young man actually said that his laboratory has developed thermal insulation materials and can enter mass production immediately.

How could he remember the Sanchi Research Institute? This research institute seemed to have just been established not long ago, right?

Ye Zhou on the other side nodded and replied:

"Yes, we have been working on it for 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 then."

"The principle of carbon foam can indeed be used as the base material of TBC. Okay, Ye Gong, I will contact you soon!"

Gao Jun said in high spirits.

The two continued to chat about materials for a few more words. Ye Zhou mentioned anti-perovskite structure negative thermal expansion materials, which surprised Gao Jun even more.

Could it be that what we want to do this time is not just imitation?

Judging from the current engine design documents, all the high-temperature resistant materials required for the blades can be produced domestically. At this time, if a new material is proposed, and it is a negative thermal expansion material that has only been verified in the laboratory, the answer is probably only one.

He also had to warm the engine.

In other words, the final thrust of this engine may be more than the 70 tons marked on the drawing.

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

At the end of the conversation, Ye Zhou took the initiative to stop the topic and said:

"What I just said are actually just ideas 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 were asked to optimize the design, he would not be able to complete the task within the project time.

The long technical topic finally ended, and everyone in the office began to make overall work arrangements. The main chatter was Chen Hao. It was not until about 12 o'clock at noon that a few people finally ended the topic and prepared to go out for dinner.

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

"Mr. Xu, something happened."

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

"If anything happens, please report it directly."

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

"Xiao He applied for resignation"
