When the type of engine is determined, it still can't start, and there are other requirements, such as

"What kind of engine has been decided, let's talk about it below. I'm going to make a hard condition here, and that's that engines can only be fueled by gasoline or diesel, and aviation fuel is absolutely not feasible here. After all, jet fuel is hard to find even abroad. ”

This is clear when you think about it, and of course there is no objection. Make a note of this requirement and continue the discussion.

Since it is a series of engines, then there must be a basic model, and when it comes to this model research, it is another problem.

"We have to study a basic model first, and after the basic model is determined, we will add it step by step according to this model." This is the most conventional serialized research route, and it is also the most thought by many people, including Yang Hui.

However, soon someone put forward a different suggestion, and Zhong Jianshe put forward a different idea.

"I think we should change our thinking, we do centrifugation, not axial flow, we can't use axial flow to do centrifugation, axial flow can increase the channel ratio, but centrifugal can't."

Zhong Jianjian's words are not unreasonable, the axial turbofan can increase the thrust of the engine with the smallest thrust by increasing the channel ratio, so as to form a series. However, it will not work in the centrifugal type, how can the centrifugal type expand the channel ratio?

"That's reasonable, keep talking."

Seeing Zhong Jianshe stop, Yang Hui asked him to continue, after all, Yang Hui himself had never played with such a small thrust engine before. If you don't have experience, you have to rely on everyone's efforts at this time.

See. Everyone seemed to agree with their ideas at this time, and Zhong Jianshe was more bold to continue.

"I think that at this time, since the centrifugal type cannot be used to increase the channel ratio, then we can only change the method and increase the total turbine temperature."

As soon as these words came out, it suddenly dawned on me, some patted their heads, and some patted their thighs. Anyway, each has a total expression and various actions, indicating that he understands. It is said that increasing the total temperature of the turbine is also a major treasure of increasing the thrust, which is the most popular in the era of turbojet engines. In the era of turbofans, the increase in thrust capacity is not as obvious as the expansion of the channel ratio of the turbofan, and at this time, Yang Hui figured out all the ideas of Zhong Jianjian.

"You have to mean that you first make the engine of the whole series of thrust engines close to the middle thrust, and then change the thrust by changing the turbine of different materials and changing the total turbine temperature of the engine."

This is really a good idea, as long as an engine is made, the later series of engines can not be changed without changing the design, only need to change the turbine material, according to the total temperature of the material, change the strength of the flame burning, so as to change the thrust of the engine, the modification of these two points is really not too simple.

Hearing Yang Hui say his last thoughts, Zhong Jianshe was surprised and very happy.

"Yes, Team Leader Yang, that's what I mean, according to this method, we can almost develop a series of engines with the money from developing one engine. It's easier to change the materials we already have than to constantly change the engine channels, which is the best fit for our situation. ”

Immediately, Yang Hui wrote down this point. While writing, he said, "Zhong Jianjian, right, I wrote down this merit for you, and when the time comes, I will ask you for credit, and I must reward you well, this is really a classic idea." ”

This is a young man with ideas, Chinese researchers are not lacking in innovation, the reason why later generations see many Chinese products is because researchers have no motivation to innovate.

Yang Hui believes that as long as there are conditions, scientific researchers are motivated, and their own guidance is not too difficult to make China's aviation industry the first echelon of the world's aviation industry, everything just needs a good start.

Without thinking about it anymore, Yang Hui planned to continue to determine the remaining key points.

"Okay, let's move on to how big and how much weight the entire engine needs to be controlled."

"I think we should ......"

…………

Looking at the time, and then looking at the notes he had written, Yang Hui felt that the entire data that needed to be determined was almost there, and the rest was to report to the director. Then you can start to do engineering design according to these requirements, of course, due to some reasons in the design, it will definitely lead to the final data and the current data, but it will definitely not be too big, this is certain.

Closing the notebook, Yang Hui moved his neck.

"Okay, everyone, these key data are settled, now it's a few minutes before the end of work, we can't do anything, get off work early, come to work early tomorrow, let's get off work."

"Okay, okay" After a composite sound, they all stood up and packed up their things and prepared to get off work.

"Wait, I'll announce good news." At this time, Yang Hui remembered that he hadn't told everyone the news that the dormitory had been arranged. So he immediately took out the list in his pocket and announced.

Looking at the list in Yang Hui's hand, everyone was wondering what it was. Fortunately, Yang Hui will not be appetizing, and continues to hold the list and say,

"This is the dormitory arranged for us in the institute to come out, I will read it to you, Xie Lianfa, single dormitory 306; Zhong Jianjian, single dormitory 307......"

After reading the dormitory arrangement, he heard a burst of cheers and shouts, and Yang Hui couldn't help but laugh together.

"Okay, you can move after work. I went to see the dormitory, we were all on the third floor, all single rooms, and the institute still took good care of our project team. ”

Here Yang Hui played a trick, in fact, the institute took good care of these college students, but now the six new college students in the institute are all concentrated in a project team, of course, it can be said that they take good care of the project team. This is also to increase the cohesion of the project team.

"Yes, yes, yes...... Come, let's go, let's move, Team Leader Yang should move together. ”

Smiled and shook his head, he had already moved in, where do he have to move now, his business is not finished yet, Yang Hui picked up the notebook and walked out.

"I won't be able to, now I'll go and see if the director is gone, and if he doesn't leave, I'll go and tell me the data we agreed here."

"This team leader Yang is really diligent in the past!" Long Derong saw Yang Hui leaving and joked quietly.

"Don't say that, it's good that we're also doing it for the financial resources of the institute this time, don't think so much, report more, and be safe." Zhong Jianjian, who grew up in the base, is very familiar with everything in the base, knows that this opportunity is not easy to come by, and strives to help Yang Hui maintain the unity of the project team.

"Aha, I'm just joking, don't take it seriously!" Long Derong immediately changed his tune.

…………

Coming out of the guest house, five college students, each carrying a bag on his back, and a large bag in his hand at the same time. It looks quite heavy, but these people are running quite fast, but the heavy wheezing along the way still clearly indicates that they are tired, but if they are tired, they will have their own dormitory immediately, and everything is worth it.

"Ah, it's finally up. It looks like this building is quite new, and the office is really good for us. Pan Wen, who hadn't spoken much, finally spit out a sentence.

Putting down the bag in his hand, he took out the new key he had just received from downstairs, opened the door smoothly, and Liu Wang picked up his things and walked inside. At the same time, the heads of several other people also rose in, and they couldn't wait to see the new dormitory.

"It's okay, at least it's better than when I was in college, I don't know how much, it's really good." Long Derong was afraid of the table with his big powerful hand. It looks like it's going to be a test if the table is firm or not.

"Hey, don't shoot me badly, go to your room and shoot it." Liu Wang hurriedly stopped Long Derong's behavior.

"Hmmm! Yes, I'll go back too, and I'll have to pack up my things first. Seeing that the dormitory was not bad, Zhong Jianshe left Liu Wang's crowded hut after speaking, picked up his bag and walked out.

"Yes, yes, I'm leaving, you tidy up slowly," said a group of people who also went back to the dormitory to tidy up their things after seeing the appearance of the dormitory.

It took about ten minutes to clean the room, and Zhong Jianshe lay down happily on the bed.

This single room is really unthinkable, it's still a building. At that time, the northerners came to know the climate conditions here, and they built all the bungalows, and it began to leak after a few years of rain, which was really hard.

Thinking of this, Zhong Jianshe thought of Yang Hui again: This is really a young man with ideas, why is it that at the same age, others are so capable, and he is ・・・・・・・

I couldn't figure it out, Zhong Jianshe decided not to think about it anymore, as long as there was money in the institute, there would be projects in the future, and the project would be done when the project was arranged above. Zhong Jianshe didn't know that he should not think much about him and do his own thing, which was deeply appreciated by Yang Hui in the back, and he went to the position of the chief engineer of the project.
