After venting his excitement on the phone, Zhou Yonghang's emotions finally calmed down.

He remembered that Du Yishan seemed to have said that the flutter analysis of the wing and the control rate design of the active stability control system were all done by one of the students of the other party.

"Lao Du, when the Y-7-200A aircraft is replaced with a new wing and completes its first flight, I must ask your superiors for credit and your student!"

Du Yishan and Zhou Yonghang on the other end of the phone are also old acquaintances, where would they not know what the latter was thinking:

"Heh, the matter of asking for merit is mentioned so proactively, this is my student?"

"Don't say that, what are your students, my students, they are all students of the country."

Zhou Yonghang, who was debunked his thoughts, did not feel embarrassed, but continued:

"Besides, your Lao Du is now relegated to the second line, and there is no main model in his hand, such a talented young man, after graduation, he still has to go to a front-line unit like us to experience and experience."

However, Du Yishan was completely unmoved:

"You old fox, I can hear the voice of your heart in Sheng Kyoto."

"But you're going to miscalculate this time, this student is only in his third year this year, and he is a few years away from graduation, so you probably won't be able to touch his light before he retires."

"Junior?"

Zhou Yonghang, who sat back in the chair on the other side, had a ghostly expression: "Don't fool me, I've read all the technical documents, and I don't talk about many things in it at the undergraduate level." ”

"If you don't believe it, you can come to our Jinghang to take a look, it's no good for me to lie to you about this kind of thing, besides, everything has to wait for the class to talk about it, what kind of genius is it?" There are many students who take graduate courses in advance at the undergraduate level every year, and it can only be said that they are indeed geniuses. ”

Having said that, Du Yishan can also understand the mood of his old friend.

Even if it was himself, he was repeatedly shocked by Chang Haonan when he first came into contact with him.

"It's really a junior?" Zhou Yonghang listened to Du Yishan's tone, which didn't seem to be joking, so he had to sigh and say with some pity:

"That's really no way, there are still ten years of work until I graduate from the doctorate, I can't wait......"

There are still very few people who know about Chang Haonan's direct doctoral study, so Zhou Yonghang calculated the time according to the normal master's + doctoral process.

However, at this time, Du Yishan changed his words:

"But Lao Zhou, you are right just now, such a talented young man really has to go through the first-line project experience to become a great tool."

"Oh?"

Zhou Yonghang felt that things seemed to be taking a turn for the better, and he became interested in it instantly: "What do you think?" ”

"Hmm...... I need you to do me a favor. Du Yishan thought for a moment and then replied:

"But the ugly thing is ahead, although I am indeed ready to involve him in major projects in advance, but your new airliner is not good, not qualified."

"Are you going to make him ......?"

Considering that Du Yishan was holding a meeting at the 601 Institute, and he felt that the Yun 7-200A project was not qualified, Zhou Yonghang guessed the other party's thoughts almost immediately.

"Just guess it, don't say it." Du Yishan knew that Zhou Yonghang would definitely be able to comprehend what he meant, so he didn't let the other party continue: "You just say that you can't help with this favor, right?" ”

There was silence on the other end of the line for a few seconds.

"Say, what do you want me to do?"

Huaxia Aviation Industry is a whole, although there will be some competition between the institutes, but Zhou Yonghang, as an old comrade, is not so narrow as to only take care of the interests of his own 603 institute.

Seeing this, Du Yishan was not polite, and directly said his thoughts:

"Don't wait until the first flight of the new wing is completed, haven't you already determined that the active flutter control method is feasible, and now find a way to make it an advanced experience as soon as possible, and publicize it within the aviation system first."

By the mid-90s, although the importance of the 83 Project had not caught up with the No. 10 and No. 11 projects, it was definitely not something that Du Yishan could do with a single sentence if he wanted to stuff an undergraduate student into it.

At the very least, he had to prove that the undergraduate was capable enough.

And for such a large project, just a paper on the Journal of Aeronautics is definitely not enough.

Therefore, Du Yishan needs to let the 603 Institute first publicize the achievements of active flutter control, and when Chang Haonan is the main contributor to this advanced experience, the weight will be completely different.

"Okay, I'll have someone do it right away."

Zhou Yonghang understood what Du Yishan wanted to do after a little thought, so he decisively agreed to the latter's request.

Originally, he was going to end the call like this, but then he remembered another thing:

"By the way, Lao Du, after the new wing of the Yun 7-200A this time, it has actually been completely reborn compared with the old Yun 7.

So I think it's a bit inappropriate to continue to call this name, both from the technical side and from the future market side, so you can help us think of a new name. ”

The imitation prototype of the Y-7 aircraft is the An-26 transport aircraft, which was put into service in the Soviet Union in the late 60s, and the reputation of both names is relatively average.

Especially in the late 80s and early 90s, after Huaxia Civil Aviation came into contact with the Tu-154M, MD80, Boeing 757-200, which were put into use in the 80s, it quickly lost interest in continuing to operate the Y-7 and Y-8 series transport aircraft.

The improved version of the Y-7-100 developed by the 603 Institute on the basis of the Y-7 was quickly eliminated after a short service history.

Therefore, Zhou Yonghang actually had the idea of changing the name of the new passenger plane to start again, just in time for the opportunity of this wing overhaul, as long as it is proposed, it is estimated that it will be approved.

"Name ......"

This question stumped Du Yishan.

The naming of aircraft in the past in the main Huaxia is really not fancy, it is a simple type of aircraft - digital numbering, such as Yun-8, Qiang-5, J-7 and the like, so almost no one has ever thought about this problem.

"Forget it, there's no rush in this matter, just give me a call when you have an idea."

"That's fine, I have time to ask Xiao Chang their opinions, young people, their ideas will be more flexible than ours."

After ending the call with Zhou Yonghang, Du Yishan made a direct phone call to Beijing Airlines University.

The first thing is to tell Chang Haonan about the news that his active flutter control system has successfully passed the verification.

However, Chang Haonan actually knew the news, so he didn't show too much surprise.

Because he happened to be looking at the system panel before, and then found that his research points suddenly increased from 36 to an astonishing 76.

Obviously, in the few things he's done so far, only flutter analysis and active flutter control methods can have such a huge impact.

It's just that this reaction made Du Yishan look at Chang Haonan a few times-

Old and serious, not arrogant or impatient, he is definitely a person who can achieve great things.

So he quickly turned the topic to the second thing, that is, to give the Y-7-200A a new name.

This surprised Chang Haonan.

The main reason is that I didn't expect this matter to be in advance, and it fell on my head.

After thinking about it for a while, Chang Haonan finally decided to use its name on the original timeline.

"Mr. Du, I think that since this is the first passenger aircraft designed by our Huaxia in accordance with the new international standards, it is better to call it 'Xinzhou'."
