Turbofan 10, as the core of the domestic third-generation aircraft, is pinned on by too many people.

As a multinational hybrid engine, its core engine mainly comes from the SFM56, which is the core engine of the F110.

The F110 is an enduring engine with a double fulcrum drum shaft, a large shaft inclination combustion chamber, intermediate bearing twin rotors, and a fan structure with a clear frame.

Not only is it good now, but even the next few new engines have borrowed a lot from the core engine design of the F110.

As for the detailed design and optimization of the engine, a lot of references are made to the AL31F.

Therefore, the turbofan ten can be regarded as a combination of woolly bear, eagle sauce and three domestic technologies.

Of course, compared to the F110 as the core machine, it is better, and the AL31F as a detailed reference has many flaws.

For example, there is surge at low altitude and high table speed, which also leads to the fact that the turbofan ten originally developed in China cannot be really installed and used.

Surge is mostly caused by the poor flow state of the incoming flow introduced by the engine (such as uneven static pressure caused by the attached surface layer, or the wake of the front engine sucked into the air intake, etc.) or the compressor blade stall caused by blade resonance.

The projects handed over to the Rocket Research Institute were also mainly material.

After all, although they are both engines, the structural gap between liquid rocket engines and aero engines is still relatively large.

Liquid rocket engines do not work for a long time, while aero engines require at least a few hundred hours of service life.

Therefore, the first WS-10 sub-project received by the Rocket Research Institute was the development of engine tail nozzle materials.

Although there are many internal differences between liquid rocket engines and aero engines, the material requirements for the tail nozzle are basically the same.

It must have the performance of high temperature resistance and high impact resistance.

It's just that the requirements for temperature and impact strength are different.

The temperature requirements of rocket engines are higher, basically above 3,000 degrees, and the requirements for aero engines are slightly lower, basically within 2,000 degrees.

However, the service life of aero engines is more demanding.

Zhang Xingyang did not take care of this project, but let the material research room of the research institute do it.

These are necessary for these fledglings who have just come out of school to grow up.

Zhang Xingyang can't do all the scientific research tasks alone, he needs to be able to help his scientific research companions, not just follow his ass and follow the fart.

Of course, Zhang Xingyang didn't completely let it go, but still pointed out the direction of exploration for them.

At the morning meeting in the materials research room on Monday, Zhang Xingyang pointed out:

"Without changing the basal embryo and source gas, we have to change the time of gas phase immersion and the method of outer coating.

To control the best performance of the material in the range of 1000 degrees Celsius to 2000 degrees Celsius, and find ways to improve the service life of the material. ”

Zhang Xingyang looked at the people in the conference room who were looking at him seriously, took a sip of water and continued:

"That's what you do next, how to control the time and materials to achieve the effect.

Okay, what questions do you guys have? ”

At this time, everyone in the materials laboratory raised their hands and began to ask questions.

Zhang Xingyang first ordered a short-haired girl with a little baby fat on her face.

As the first person to speak at the meeting, Han Juan was a little nervous, but her thinking was relatively clear:

"Dean, our laboratory has not yet obtained the newly produced basal embryo, do we want to use the previous basal embryo for experiments?"

The problem of the base embryo is what Zhang Xingyang did not want, after all, he has been paying attention to the research and development of the control system recently, and his attention to this aspect has naturally declined.

frowned and said:

"I will ask the 703 factory about this matter, and before the newly produced carbon fiber base embryo arrives, I will use the previous test to explore the performance change curve caused by temperature control."

After Han Juan heard Zhang Xingyang's explanation, she didn't have anything to ask, and sat back in her seat.

Next, Zhang Xingyang answered several people's questions one after another, and there were all types.

There are those who ask questions about the technical route, those who want to apply for equipment for microscopic observation, and even those who are not suitable for the canteen of the unit and want to change the cuisine of the canteen.

It really opened Zhang Xingyang's eyes, there are really people in this world who can't eat a little spicy, and they have to go to the hospital if they eat pickled and spicy cabbage in the canteen of the unit.

However, Zhang Xingyang was also a little speechless, this kind of thing should be told to himself, just say no to the canteen master directly.

Fortunately, Su Xiao's question in the next one is still relatively normal.

"Dean, isn't it a bit hasty for you to make me the head of the lab? I don't have any special scientific abilities. ”

Although Su Xiao felt that her ability was not good and she couldn't bear such a heavy burden, Zhang Xingyang still felt that there was nothing wrong with her.

Previously, when she was the leader of the science and technology guidance group, she was able to arrange the work of the team members well.

In fact, the members of the science and technology guidance group at that time were basically composed of personnel from the materials research laboratory.

"I don't think there's anything wrong with you being the person in charge, when you were in the 703 factory for technical guidance before, you didn't manage it very well."

Su Xiao also wanted to argue with Zhang Xingyang, but was stopped by Zhang Xingyang reaching out.

"Don't say it, it's up to you, come on!"

After Su Xiao sat down, several more people stood up one after another and asked a few questions.

After Zhang Xingyang answered them one by one, this meeting ended here.

Afterwards, Zhang Xingyang came to the financial office of the Rocket Research Institute.

Uncle Liang Yi just asked someone to bring a message to himself, saying that there has been a new development in the insurance matter.

"Uncle Liang, what's going on over there with the insurance?"

Zhang Xingyang first poured himself a glass of water when he entered the door, moistened his throat and asked.

Recently, Zhang Xingyang has also understood that there is nothing good about being involved with this international insurance fund.

Sometimes Zhang Xingyang wants to directly say to the above that we will set up a space insurance fund by ourselves, so that we will no longer have to be angry with others.

"It's not bad news, the International Insurance Fund has sent a commissioner to China to conduct a special accident investigation to confirm whether to pay compensation."

Liang Yi flipped through the mountains of various documents on his desk while taking out a fax and handed it to Zhang Xingyang.

At a glance, it was to the effect that the International Insurance Fund attached great importance to the accident that occurred in China, and had sent special personnel to assess it, and it would arrive soon.

Even Zhang Xingyang, who has always been of good quality, couldn't help but complain:

"They pay attention to a ghost, and if they do, it won't drag on for more than four months!

This guy is totally farting! ”

Liang Yi nodded in agreement, but said helplessly:

"No way, now it's up to them."
