Chapter 120 Technical Difficulties of Engines

On the morning of December 12th, Ye Zhou arrived in Fengtian via the high-speed rail. He also arrived at the same time as several main 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, but due to confidentiality requirements, no large-scale welcome party was organized on site, but a small tea party was arranged in the general manager's office.

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

"Afterwards, the three of us will directly interface with you. No matter what difficulties or requests you have, you can immediately raise them, and we will carry them out unconditionally."

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

"Boss Chen is mainly in charge of overall planning. I am mainly in charge of technology, and I may also participate in some personnel arrangements and post arrangements. We can discuss specific matters later. Today I mainly want to ask, do you have any ideas about this project?" Thorough understanding?"

"Yes! Ye Gong, I have read all the technical documents, and I have marked the technical difficulties. Judging from the current situation, it is difficult to complete the production within 3 months of the project reservation, 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, but in front of Ye Zhou, he did not show Show any arrogance.

In scientific research, especially in the field of aviation development, if you have something in hand, you are a big brother.

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

"Tell me about the technical difficulties?"

"The biggest problem I've seen so far is the creep problem. Although there are blade material ratios in this drawing, and the metal ratios of each part are also marked, in the actual processing process, due to temperature control, impurities and other problems, we It does not replicate the blade material distribution 100%."

"For example, according to the requirements on the drawings, we need to use a total of 9 different metal elements to manufacture the blades. Among them, 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 balance the creep of the blades. scope."

"It's a job that requires constant testing, and it's likely that just a small difference could lead to huge problems with the final engine."

"and also."

Hearing Ye Zhou ask technical questions, Gao Jun's nature immediately came up. He talked endlessly about the various difficulties in this document, but to Ye Zhou's surprise, his attitude towards these difficulties was not the same. Not fear, but excitement.

Probably took it as a challenge.

Several other people in the office listened with gusto at first, but as the topic deepened, they gradually couldn't keep up. Even Ye Zhou, who was infused with the device, started to have a headache.

This thing has gone beyond basic aero engine knowledge and has begun to enter the fields 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 engines abroad, but the problem lies in the thermal barrier coating. This is not a simple Insulation film, but a complete set of TBC insulation system, we do not have a good TBC base material, but we still have research on anti-oxidation connection 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 it. This is a big problem, but to be honest, the resources are so sufficient this time, at worst, we have to start TBC from scratch! "

"Anyway, TBC will be launched sooner or later. We will do it at one time, and it will save trouble in the future."

"Hey, old Gao, old Gao!"

Xu Qi who was sitting beside him heard his words, and interrupted quickly.

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

There is no problem in saying that it is difficult. After all, reasonable management of leadership expectations is also a very important thing in the workplace.

However, it is a bit too inappropriate to say that it is difficult to choose the right time. We have just met.

Gao Jun, who was still immersed in excitement, suddenly realized that he also smiled awkwardly, and then said to Ye Zhou apologetically:
"Ye Gong, I'm really sorry, I've said too much all of a sudden. But don't worry, these difficulties are indeed a little bit more, but generally speaking, they should all be overcome."

"Should? What should mean?"

Ye Zhou interrupted him, frowning and asked back.

"What I should be saying is that we have a feasible plan, but the execution effect of the plan may not be as expected. For example, the TBC system I just mentioned, in fact, we can add ZRO2 and Y2O3 to the metal substrate 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 big question”

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

He originally wanted to bombard the other party to see how much preparation he had made for this project. If he was hesitant or arrogant when facing his own problems, then what is Ye Zhou's expectation for this project? will be greatly reduced.

Fortunately, Gao Jun's answer made him very satisfied.

Being able to tell the alternative plan on the spot proves that he has really put in the effort to study it. Even if he can't explain all the problems clearly 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 Lab is just making a kind of heat insulation material, which is no longer ready for industrial production. 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 enlarged, and he looked at Ye Zhou in disbelief.

He knows too well how many resources are needed for the research and development of a new type of material. From formula design to laboratory preparation, he does not know how many people will work hard.

To achieve stable manufacturing is another long story.

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

How could he remember the Sanchi Research Institute? It seems that this research institute has just been listed, right?

Ye Zhou on the opposite side nodded and replied:
"Yes, it has been working for a while. The material mainly uses the principle of carbon foam. I will give you the contact person of the research institute. Then you can coordinate and cooperate."

"The principle of carbon foam can indeed be used as the base material of TBC, okay, Ye Gong, I will contact you in a while!"

Gao Jun said excitedly.

The two continued to talk about materials, and Ye Zhou mentioned anti-perovskite structure negative thermal expansion materials, which surprised Gao Jun even more.

Could it be that this time it is not just imitation?

Judging from the current design documents of the engine, 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 warms up the engine.

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

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

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

"What I just said is actually just a vision 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 do optimization design, he really can't complete the task within the project time.

Finally, the lengthy technical topic was over, and everyone in the office began to coordinate their work arrangements. The main chatter was Chen Hao. It was after twelve o'clock at noon that the few people finally ended the topic and prepared to go out for dinner.

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

"President Xu, there is something wrong."

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

"If there is anything, report it directly."

The secretary nodded, handed the document to Xu Qi, and said:
"Xiao He applied for resignation"
