On the other hand, after agreeing to Du Yishan's request, Zhou Yonghang's side of the 603 Institute also acted very quickly, and it took less than ten days to declare the "flutter simulation and active control of the large aspect ratio straight wing" as an advanced technological achievement.

And Chang Haonan's name ranks first among the completers.

Needless to say, this propaganda effect is not too much.

Therefore, after returning to the capital from the 601 Institute, Du Yishan almost immediately found the chairman of Huaxia Aviation Industry Corporation, Liang Zhuoping.

"Old Du?"

Liang Zhuoping was stunned for a moment when he saw Du Yishan at the door, and hurriedly got up to greet him:

"I'm just looking at the advanced technology achievements submitted by 603, and you can be said to have made an immortal contribution to our Huaxia aviation industry this time."

"Eh, don't be a sycophant."

Du Yishan waved his hand at Liang Zhuoping and sat on the sofa next to him:

"You should have read the list of completers, and I just added a name at the end as a project manager.

This achievement is all made by students, and there is no need for me, an old bone, to steal the limelight from young people. ”

Liang Zhuoping is a person, after hearing Du Yishan's answer, he continued without changing his face:

"You can't say that, Du Lao, aren't the talents who complete the project also trained by you? That's a credit to you. ”

While speaking, he took the thermos and tea cans from the side, and made a cup of tea for Du Yishan, who had just sat down.

After just a few rounds of conversations, Liang Zhuoping had roughly guessed the purpose of Du Yishan's trip, which was probably related to the other party's students.

This made him breathe a sigh of relief.

With the change of the times, many factories that used to support the aviation industry have been transformed into private enterprises.

But it's the same people who run these businesses.

In order to get orders from the aviation industry, these companies are simply eight immortals across the sea, each showing their own magical powers, and people often come to Liang Zhuoping and ask him if he can designate a certain company as a supplier.

In terms of his status, most of them are not under much pressure.

But if Du Yishan also comes to do this, it is indeed a bit troublesome.

"The student named Chang Haonan who ranks first has just joined our research group, so if you have to say that I have cultivated talents, then my old face is a little panicked."

Du Yishan decided not to continue to go around in circles with Liang Zhuoping:

"Zhuo Ping, guess how long it took him to complete the project of the 603 Institute?"

"Since Elder Du asked so, the answer must be very short."

Liang Zhuoping sat back on his office chair, leaned back in the chair and thought for a moment:

"A month?"

"It's too long." Du Yishan smiled and shook his head.

"A month is still long?" Liang Zhuoping raised his eyebrows and couldn't help but sit up straight.

He used to be an engineer, but he only later moved to a management position, so he knew a little bit about these technical issues, even if he was not proficient.

According to the materials submitted by 603, the realization of this achievement in aircraft design is not complicated, but the principle is very exquisite, and it also involves a lot of basic mathematical theory and computer simulation applications, and the development process must be a lot of work.

So a month is actually what he thinks is a very exaggerated estimate.

"That'...... Half a month? ”

Du Yishan still shook his head.

"It can't be a week?"

Liang Zhuoping was already a little nervous, and even he felt ridiculous to this answer.

It's only 168 hours a week, even without sleep, and I can't even think of it unless the whole development process doesn't take any detours at all.

"One day." Du Yishan stretched out a finger: "On the first day he joined our group, he sorted out the theory of nonlinear flutter simulation and active flutter control. ”

If this answer came from someone else's mouth, Liang Zhuoping's first reaction would probably be to drive the other party out directly.

Only charlatans would dare to speak so wildly.

But this is Du Yishan after all.

The reason in his mind told Liang Zhuoping that this matter could never be true, but emotion also told him that Du Yishan, as a senior academician, could not be idle enough to have fun with him.

After a few minutes of rapid brain operation, Liang Zhuoping finally reluctantly found an answer that could be recognized by both reason and emotion:

"Will it ...... Is it that he has actually studied this for a long time, but he gave this achievement to you as a gift on the first day of joining the group? ”

As a result, Du Yishan directly vetoed:

"Impossible, Yun 7-200A, oh, it should be called Xinzhou 60 now, although it is not a classified project, but he was just a junior undergraduate who was still in class before he joined the group, and it is impossible to have access to relevant data."

"A junior undergraduate?"

Hearing a loud sound, the lid of the cup in Liang Zhuoping's hand fell directly on the table.

Although the cup in the other hand did not fall, a lot of water spilled out of it, soaking his shirt.

Since accepting Chang Haonan as a student, everyone Du Yishan has seen has almost always behaved the same when they hear each other's identities.

So he is no longer surprised by Liang Zhuoping's performance.

"That's right, this was the first project he came into contact with, and no one had even told him how to complete a project before, and in this case, he solved it completely on his own in one day."

Du Yishan put the teacup in his hand on the table and looked at Liang Zhuoping, who didn't even think to wipe off the water stains on his shirt:

"That's why I'm here today to tell you about this student."

Seeing that the fire was almost over, Du Yishan put forward his idea bluntly:

"Such a student, whether it is theoretical skills or talent in engineering application, is something I have never seen before, if he is like others, step by step to graduate classes and do some ordinary topics, I think it is not only a loss for him, but also for our Huaxia aviation industry."

Having said that, how could Liang Zhuoping not know what Du Yishan meant.

"Do you want to put him on our side and be directly involved in the project?"

Du Yishan nodded: "There is one more thing you may not know, a few days ago, Lu Yuying from the 611 Institute went to Jinghang University to find Chang Haonan and exchanged some questions about the design of the mandibular air intake, which should be related to the new J-7 model they are preparing to design." ”

"J-7F? That project of 611 also has something to do with him? ”

Liang Zhuoping only learned about such a project two days ago, but because it was self-financed by the factory, the head office only had the right to know, so the information submitted was relatively simple, and it did not mention all the technical details.

At this time, the balance in his heart had already tilted significantly:

"That'...... What does Du Lao mean is to let this Comrade Xiaochang help the 611 Institute to improve this J-7 model? ”

"Of course not, the J-7F was self-financed by Rongcheng, if I wanted him to participate in that project, I wouldn't have come to you."

Du Yishan stood up as he spoke, walked slowly to Liang Zhuoping's desk, and looked at his former subordinate, now the head of Huaxia Aviation Industry:

"I want him to participate in the 83 Project!"
