Chapter 48 [Please read! 】New boat, set sail
After venting his excitement on the phone, Zhou Yonghang finally calmed down.
He recalled that Du Yishan seemed to have said on the day he came to Institute 603 that the flutter analysis work of the wing and the subsequent control rate design of the active stability control system were all completed by one of his students.
"Lao Du, when the 7-200A aircraft is replaced with new wings and completes its first flight, I will definitely give you and your student credit for it!"
Du Yishan and Zhou Yonghang on the other end of the phone were also old acquaintances. How could they not know what the latter was thinking:
"Haha, you are so proactive about asking for credit. Do you think you are interested in my students?"
"Don't say that. Your students and my students are all students of the country."
Zhou Yonghang, who had his thoughts revealed, did not feel embarrassed, but continued:
"Besides, Lao Du is now relegated to the second line, and he doesn't have the main model in his hand. Such a talented young man still has to go to a first-line unit like ours to gain experience after graduation."
But Du Yishan was completely unmoved:
"You old fox, I can hear the abacus in your heart even in Shengjing."
"But you must have miscalculated this time. This student is only in his third year of college this year and is still a few years away from graduation. You probably won't be able to benefit from him before you retire."
"Junior year?"
Zhou Yonghang, who sat back on the chair on the other side, looked like he had seen a ghost: "Don't lie to me. I have read the technical documents. There are many things in them that are not covered at the undergraduate level."
"If you don't believe it, you can come to our Beijing Airlines and have a look. It won't do any good if I lie to you about this kind of thing. Besides, how can you be called a genius if you have to wait for everything to be taught in class? Take a graduate course in advance for your undergraduate degree. There are quite a few students every year, and I can only say that they are indeed geniuses.”
Although he said that, Du Yishan could also understand his old friend's mood.
Even he himself was repeatedly shocked by Chang Haonan when he first came into contact with him.
"Really a junior?" Zhou Yonghang heard that Du Yishan's tone did not sound like he was joking, so he could only sigh and said with some pity:
"Then there's really nothing we can do about it. It's still ten years before I graduate with a doctorate. I can't wait any longer..."
Very few people know that Chang Haonan made an exception and went directly to study for a doctorate. Therefore, Zhou Yonghang calculated the time according to the normal master + doctorate process.
However, at this time, Du Yishan changed the subject:
"But Lao Zhou, you were right just now. Such a talented young man really needs to go through front-line project experience before he can become a great person."
"Oh?"
Zhou Yonghang felt that things seemed to be turning around, and he suddenly became interested: "What do you think?"
"Well... I need you to do me a favor." Du Yishan thought for a moment and replied:
"But to start with the ugly story, although I am indeed prepared to let him participate in major projects in advance, your new passenger plane is not good and not qualified."
"Are you going to let him..."
Considering that Du Yishan was having a meeting in Institute 601, and that he actually felt that the Yun 7-200A project was not qualified, Zhou Yonghang guessed what the other party was thinking almost immediately.
"Just guess it, no need to say it." Du Yishan knew that Zhou Yonghang would definitely understand what he meant, so he didn't let the other party continue: "Just tell me whether you can help me with this, right?"
There was silence on the other end of the phone for a few seconds.
"Tell me, what do you want me to do?"
China Aviation Industry is a whole. Although there will be some competition between various institutes, Zhou Yonghang, as an old comrade, is not so narrow-minded that he only cares about the interests of his own 603 Institute and one family.
Du Yishan was not polite when he saw this and directly expressed his thoughts:
"Don't wait until the new wing completes its first flight. Haven't you already determined that the active flutter control method is feasible? Now find a way to turn it into advanced experience as soon as possible and publicize it within the aviation system."
By the mid-1990s, Project 83 was no longer as important as Project 10 and Project 11, but it was definitely not something Du Yishan could do with just one sentence.
He must at least prove that this undergraduate student has sufficient ability.
For such a large project, just one paper in the Journal of Aeronautics and Astronautics is definitely not enough.
That's why Du Yishan needs to let the 603 Institute publicize the results of active vibration control first. By then, Chang Haonan, as the main contributor to this advanced experience, will have a completely different weight.
"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.
He originally planned to end the call like this, but then he remembered something else:
"By the way, Lao Du, after the Y-7-200A was equipped with new wings this time, it has actually been completely transformed compared to the old Y-7.
So I think it is inappropriate to continue to call it this name, both from a technical perspective and from a future market perspective. Please help us think of a new name. "
The imitation prototype of the Y-7 aircraft is the An-60 transport aircraft put into use by the Soviet Union in the late 26s, and both names have a relatively average reputation.
尤其是进入80年代末90年代初，华夏民航接触到图154M、MD80、波音757-200这些80年代投入使用的新型飞机之后，更是迅速失去了继续运营运7、运8系列运输机的兴趣。
The previously improved version of the Yun-603-7 developed by 7 on the basis of the Yun-100 was quickly eliminated after a short period of service.
Therefore, Zhou Yonghang actually had the idea of changing the name of the new passenger plane and starting over. It just happened to catch up with the opportunity of this major wing modification. As long as he proposed it, he would probably get approval.
"give a name to……"
This question stumped Du Yishan.
The main reason is that the naming of Chinese aircraft in the past was really nothing fancy. They were just simple aircraft types-numeric numbers, such as Yun-8, Qiang-5, JH-7, etc., so almost no one has ever thought about this issue.
"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 and the others for their opinions. Young people have more flexible ideas than us."
After ending the call with Zhou Yonghang, Du Yishan made a direct call to Beijing Hang University.
The first thing, of course, is to tell Chang Haonan that his active vibration 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 scientific research points suddenly increased from 36 to an astonishing 76.
Clearly, of the few things he has done so far, only chatter analysis and active chatter control methods could have such a huge impact.
But this reaction made Du Yishan look at Chang Haonan a few times -
Mature and prudent, neither arrogant nor impatient, he is definitely a person who can achieve great things.
So he quickly turned the topic to the second thing, which was to give the Y-7-200A aircraft a new name.
This surprised Chang Haonan.
Mainly because I didn't expect that this matter would happen in advance and it would fall on me.
After thinking for a moment, 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 China in accordance with the new international standards, we might as well call it 'Xinzhou'."
