Chief Master Yu called these people, and naturally understood the general situation of these people. Chief Master Yu has long wanted to sort out these people, and this is an excellent opportunity to let Yang Hui be the leader of the team, not only to support Yang Hui, but more importantly, to let those thorns pop up.

To start a big project, first rectify the scientific research team, the more than ten pneumatic personnel in the institute, there are still some willing to do things, it is particularly important to identify the real thorns, not to let these individual guys in the project at a critical moment to break things.

In order for these thorns to pop up, Chief Master Yu now needs to give them a signal.

"Let's come with me, let's take you to meet the professor and his students from Beihang first. Then you have to do a good experiment, I have other things to do, and I can't be with you later. ”

What I said earlier is not the point, but the point is that Chief Master Yu will leave in the back. That's why these bad monkeys who don't have a tiger to suppress will come out. As for whether Chief Engineer Yu has left, this is obvious, the only projects that the new aircraft needs to cooperate with foreign countries are avionics and radar, and the negotiation of these projects needs to be carried out in the imperial capital. In this era, foreign-related negotiations must be carried out at the feet of the Son of Heaven, otherwise who knows what you do.

Therefore, Chief Master Yu's 'leaving' is to paralyze these young generals, and when the time comes, Chief Master Yu will definitely not be stingy with the few dismissal places in his hands. Public institutions are all iron rice bowls, and generally you don't have to worry about being dismissed, but there will still be so many dismissal places every year, in order to use them at this time.

At this time, he finally came to Beihang University, and the professor of aerodynamics of Beihang Airlines, who had been coordinated early in the morning, came to greet Chief Master Yu. This has to be received, and now I am worried that there is no money to do the project, so this is coming, not only to send the project but also to the funds, which must be received.

The old professor, who is an old pedant, wears thick glasses is almost essential, his hair is a little gray, and his clothes don't look very new, but they are very clean and tidy, which is indeed what an old pedant should look like.

"Hello, Chief Master Yu, I am Zhu Jiangcheng, and I will complete this new pneumatic test with your personnel this time. Of course, there are a group of my students who will do this with me, there are about a dozen students, these are all graduate students, and they can still be technically started. ”

Let the graduate students do it, this can only be seen here by the graduate supervisor, and there are graduate students in other places who are not quickly entrusted with important tasks, so there is still this kind of situation. Yang Hui can already imagine what this Professor Zhu looked like when he saw the technical capabilities of this group of technicians brought by the base.

Hearing these words, Chief Master Yu was already going crazy. Graduate students, this is a rare graduate student, and there are probably only so many people who graduate in the whole republic of aerodynamics in a year, these are all of them

I can't think about it anymore, Chief Engineer Yu began to ask about business, and the wind tunnel test must be indispensable for the wind tunnel, which is a must.

"That Professor Zhu, how to arrange this wind tunnel, the low-speed wind tunnel is all a matter of your words."

Chief Engineer Yu's words are true, how can there be no wind tunnels in aerospace colleges. However, it is really troublesome to use a wind tunnel if you are not an acquaintance, even if you have the above to say hello, it doesn't matter, it is still laborious to use. The wind tunnel is generally managed by special personnel sent by the school, and the aerodynamics major who often deals with the wind tunnel is naturally related, Professor Zhu is like this, they are all at the level of professors, and this wind tunnel can be arranged with higher priority.

Professor Zhu walked over to the desk and took out some materials, which seemed to be experimental arrangements or something.

"We have a low-speed wind here in our school, and we can complete the low-speed test, and I will coordinate the high-speed wind tunnel when the time comes, and there is also a place in the imperial capital, and the only transonic wind movement is not easy to find, only when the time comes, I will go to the southwest side of the big wind tunnel group test, where a new transonic wind tunnel has been completed, I heard that the performance is very good, I will take this opportunity to see this new guy."

Speaking of this, Professor Zhu looked excited, this can be understood, aerodynamics has a special plot for wind tunnels. Wind tunnels are different from general test equipment, this thing is too complicated, too expensive, and the average country cannot afford it, and only large countries are qualified to build and use it.

So with the completion of the new wind tunnel, it must be a blessing for the whole industry, and if you have the opportunity, you must go to worship, this is a must.

After saying this, Chief Master Yu called Yang Hui to Professor Zhu and introduced Yang Hui to Professor Zhu.

"Professor Zhu, this is Yang Hui, the leader of the pneumatic team of our base this time, he is very young, but he has some unique insights in technology. But it's a pity that this kid gave up the opportunity to continue his graduate studies and joined the work in advance, and the aerodynamic theory of the new machine was probably put forward by him, so now when you do the pneumatic test, I hope you will give him more guidance. ”

Professor Zhu looked at Yang Hui and began to search for an impression of Yang Hui in his head, and suddenly remembered that he saw a paper in a journal not long ago that was signed by Yang Hui, but when he thought of that paper, Professor Zhu was strange.

"Yang Hui, right, you just graduated from college, and you published a paper on the big side strip not long ago, right?"

The domestic academic community is so big, Yang Hui has just walked out of school for half a year, and his paper has only been published for a short time, so naturally there are still some memories in the eyes of professionals like Professor Zhu.

I didn't expect my paper to be published, and it seems that the counselor himself is really not thin. Thinking that I had just been reborn and hadn't adapted to it at that time, I was too excited and busy making a nondescript thing, and now I think about it, I still feel a little too far away from my position at that time.

Yang Hui knew that it was better to be humble at this time, especially in front of these old scholars and professors.

"This is my thesis, but now after actual practice, I found that we still can't use this thing, and we have to do it step by step in all aspects."

After listening to Yang Hui's words, Professor Zhu felt something, and expressed his understanding of what Yang Hui said, pointing to the sketch on the table: "So, you have adopted a conservative design on the new aircraft, abandoned the edge wing you studied, and adopted the current relatively simple double delta wing, right?" ”

I have to say that an expert is an expert who can deduce Yang Hui's thoughts from Yang Hui's words, and this Yang Hui has never spoken to anyone. Yang Hui proposed a double delta wing instead of a side wing is in the consideration of the technical difficulty of the two, in fact, the inner side of the double delta wing with a large sweep angle delta wing and the side wing have some similarities, and it can even be said that this side of the wing is a super evolution of the double delta wing is not an exaggeration.

However, after Yang Hui's calculations, the double delta wing is the most suitable for the improvement of the new training aircraft now, for many reasons. There are two main points.

First: the airfoil of the double delta wing is simple, and it will not be too much to change, and it will not be too troublesome.

Second: the double delta wing is now easier and faster to blow the test, as long as the performance of the double delta can meet the requirements, then the time requirement will be at the forefront.

These reasons are completely enough for Yang Hui to give up the side strip wing, although Yang Hui knows that in the later generations, the adoption of the edge strip wing has made the J-7 super magic modification JF17 have quite powerful performance, but now all aspects of the conditions can not meet the needs of the side strip wing.

Yang Hui affirmed Professor Zhu's words: "Yes, it is the reason for this practice that I know that in the development of a new aircraft, we should not only consider performance, but also other aspects, and finally compromise all aspects to meet the requirements, which is really good." ”

Professor Zhu still agrees with Yang Hui's statement, the school. Scientific research institutions are doing theories, and naturally the more powerful the performance, the better, but this is not the case when it comes to the design institute, which is the best to meet the requirements. After so many years of teaching, Professor Zhu still knows this truth.
