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 the 603 Institute 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 Y7-200A 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 are also old acquaintances. How could they not know what the latter is thinking:
"Oh, 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, Old Du is now relegated to the second line, and he has no one in charge. Model, such a talented young man will still have to work in a front-line unit like ours after graduation.”
But Du Yishan was completely unmoved:
"You old fox, I can hear the voice of your inner abacus even in Shengjing."
"But this time you must have miscalculated. This student is only in his junior year this year, and he 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, looked like he had seen a ghost. : "Don't lie to me. I've 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 take a look. There's no point in lying to you about things. Besides, you have to wait for everything to be taught in class before you can be called a genius. There are quite a few undergraduate students who take graduate courses in advance every year. It can only be said 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 a joke, so he could only sigh and said with some pity:
"Then there is really no way. After graduating with a Ph.D., there will still be a junior Ten years of hard work, I can’t wait..."
Not many people know about Chang Haonan’s unusual decision to directly study for a doctorate, so Zhou Yonghang calculated the time according to the normal master’s + doctorate process.
However, at this time, Du Yishan changed the topic:
“But you were right, Old Zhou, such a talented young man must go through first-line project experience before he can become a great person.”
"Oh?"
Zhou Yonghang felt that things seemed to be turning around, and he was instantly interested: "What do you think?"
"Well... I need you to help me. Busy." 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 did not let the other party continue: "Just tell me whether you can help me with this, right?"< br>
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 his own 603 Institute. Benefit.
Du Yishan was not polite when he saw this, and directly expressed his thoughts:
"Don't wait until the new wing is replaced to complete the first flight. Haven't you already confirmed that the active flutter control method is feasible? Now, we should try to turn it into advanced experience as soon as possible and publicize it within the aviation system.” Project No. 1, but trying to stuff an undergraduate student into it is definitely not something Du Yishan can do in just one sentence.
He must at least prove that this undergraduate student has sufficient abilities. For such a large project, just a 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 chatter 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."
After a little thought, Zhou Yonghang understood what Du Yishan wanted to do, so he decisively agreed to the latter's request.
He originally planned to end the call like this, but then he remembered something:
“By the way, Lao Du, after the Y7-200A was replaced with a new wing this time, it was actually the same as the old Y7-200A. It has completely changed.
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-26 transport aircraft put into use by the Soviet Union in the late 1960s, and both names have a relatively average reputation.
Especially in the late 1980s and early 1990s, after China Civil Aviation came into contact with the new aircraft put into use in the 1980s such as the Tu154M, MD80, and Boeing 757-200, it quickly lost its ability to continue operating operations. Interest in 8 series transport aircraft.
The previously improved version of the Yun-7-100 developed by 603 on the basis of the Yun-7 was quickly eliminated after a short period of service.
So Zhou Yonghang actually had the idea of changing the name of the new passenger plane and starting over. He just caught up with the opportunity of this major wing modification. As long as he proposed it, he would probably get approval.
"Name..."
This question stumped Du Yishan.
Mainly, the naming of aircraft in China in the past was really nothing fancy. They were simple aircraft types-numeric numbers, such as Yun-8, Qiang-5, J-H-7, etc., so almost no one has ever thought about this issue.
"Forget it, there's no rush for 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, their ideas are more flexible than ours.”
After finishing the call with Zhou Yonghang, Du Yishan made a direct call to Beijing Hang University.
The first thing 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.
Obviously, among the few things he has done so far, only chatter analysis and active chatter control methods can have such a huge impact.
It's just that this reaction made Du Yishan look at Chang Haonan a few times -
Being mature and prudent, neither arrogant nor impetuous, 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.
The main reason is that I didn’t expect that this matter would happen in advance, and it would also fall on me.
After thinking for a moment, Chang Haonan finally decided to use its name on the original timeline.
"Mr. Du, I think, since this is China's first passenger aircraft designed in accordance with the new international standards, why not call it 'Xinzhou'."
