The military-industrial scientific research system of the academic master.

In fact, in 1996, the first prototype of the J-10 was nearly completed, and the localization of the Su-27 was also in full swing. The People's Air Force's blueprint for the light and heavy configuration of the next three generations of aircraft was already very clear. In this case , it is impossible to equip a large number of deeply improved models of the J-7.

Therefore, even if his design is really implemented, it will only be used for foreign trade at most, replacing the status of the J-7MG in the original timeline.

Chang Haonan, who has been there, knows this very well, so he decided to use this model as a stepping stone from the beginning.

And judging from today's situation, it works well.

Of course, you can't tell Li Yan these things. Project No. 10 and Project 11 are both top secrets in Tianzi. At least he, a junior, shouldn't know too many details.

After a 15-minute break, the second half of the defense review continued. However, after the presentations of Huang Zhiqiang and Chang Haonan, everyone basically had no patience to look at the imperfect semi-finished designs.

Professor Liu Hongbo, who was sitting in the first row, was a little confused.

When he was fetching water in the water room just now, he overheard several students saying that the plan for the improved J-7 came from 601 and was not the work of Chang Haonan and the four of them.

Judging from the previous defense process, Liu Hongbo didn't really believe this statement. Whether it was Chang Haonan who made the main speech, or the other two students, a boy and a girl, who gave supplementary explanations of the calculation process, they all showed that they had a strong understanding of the design plan. own understanding.

If you just copy a design drawing, it is impossible to reach this level.

But he had to think about this possibility.

On the one hand, the design description they submitted does have the style of those in the aviation industry. On the other hand, this thing is really too big.

Whether a student's grades or even cheating in course design are trivial matters, but if a plan from the Aircraft Design Institute really leaks out, it will be a big trouble.

Even if there was a one in 10,000 possibility, Liu Hongbo did not dare to completely ignore it.

But having said that, if a high-profile interrogation and investigation is conducted just for this one in 10,000 possibility, then no matter what the result is, it will have an adverse impact on several students.

He is also thinking about asking Chang Haonan to be his graduate student!

Liu Hongbo was still in a dilemma until he returned to the office after class.

"Senior brother, although your hair is indeed very thick, you may still become bald if you keep growing it like this." A clear female voice suddenly sounded from the door.

Liu Hongbo himself is also a student of Academician Du Yishan. He just became independent from the latter's research group last year. In addition, he is only in his early thirties, so the academician's students are accustomed to calling him senior brother.

"Oh, it's Junior Sister Yao. I see that you are all busy with the 7-200 new wing recently. Why do you have time to come to me today?" Liu Hongbo turned around and looked at the door. Standing there was Yao Mengna.

"Mr. Du went back to school today. Aren't you going to meet him?" Yao Mengna asked, leaning on the door frame.

Liu Hongbo's face lit up when he heard this, and he instantly felt like a new village had a bright future.

Because he suddenly thought that the matter could be investigated by Academician Du Yishan. With the latter's connections, he only needed to make a call to Institute 601 to get it done.

"Let's go, I just have something to ask Mr. Du." Liu Hongbo picked up all the design materials handed over by Chang Haonan's group from the table, and quickly left the office with Yao Mengna.

Half an hour later, Du Yishan and Liu Hongbo were the only two people left in Du Yishan's office.

"Xiao Liu, I'm afraid you didn't just come here today just to look at me." Du Yishan sat back on his chair and pointed to a pile of things in Liu Hongbo's hand: "I have something in my hand, and I'm going to give it to you." Did I assign a task?”

"I still can't hide it from you, teacher." Liu Hongbo put the information in his hand on Du Yishan's desk with a smile on his face: "This is a big assignment handed in by a group in this aircraft design class."

"Big homework? I remember, don't you always ask Li Guang and the others to be judges together?" Du Yishan unscrewed the thermos cup in his hand, only to find that the water inside was cold, so he handed it directly to Liu Hongbo next to him. He gestured to him to pour some hot water: "What, you four don't agree?"

Liu Hongbo handed the thermos filled with water back to Du Yishan: "That's not true. In fact, we all agree that this plan is perfect."

"Oh? Then I'd like to see it."

Du Yishan finally became interested. As he spoke, he used his other hand to open the first page of the design description.

"An improved version of J-7?"

Du Yishan smiled and remembered what happened when he was surveying and mapping to imitate the J-7 when he was young.

"It's rare to have the courage to try a supersonic fighter jet, and the future is formidable."

Liu Hongbo didn't answer this time, mainly because he really didn't know what to say.

This design is not as simple as having courage at all.

Sure enough, when he turned to the third page, Du Yishan's expression became serious and the thermos cup in his hand was placed on the table.

When he turned to the fourth page, the academician had already taken out a sharpened red and blue pencil from the pen holder and began to write and draw on the draft paper next to him.

After about half an hour, Du Yishan finally raised his head and said, "Is this really an undergraduate design?"

"This is exactly why I came to you..."

Later, Liu Hongbo told Du Yishan what had happened and his concerns in short words, and said that he had called after returning to the office to inquire. There was a student named Zhou Shuwan in the group, and his father was indeed in the 601 in Shengjing. Research institute work.

"From the writing style, we can indeed see some shadows..." Du Yishan lowered his head and thought for a moment: "But after the 601 Institute completed the surveying and mapping of the basic J-7 model, it quickly handed over the follow-up tasks to the Rongcheng 611 Institute in accordance with the requirements of the superiors. and building 648 forts, that was 30 years ago.”

Du Yishan's meaning is very clear. In theory, it is unlikely that the 601 Institute has an ongoing J-7 improved project.

"Forget it, just to be on the safe side, I'll make another call to confirm." Du Yishan hesitated for a moment, picked up the receiver of a red telephone on the table, waved his hand to Liu Hongbo to wait outside the office temporarily, and then dialed a number .

A few minutes later, Du Yishan's voice came from the office: "Okay, come in."

Liu Hongbo pushed the door open again and saw Du Yishan leaning on a chair, holding his removed reading glasses in one hand and reading the design report in the other hand.

With his knowledge of his teacher over the years, he knew that this was a sign that Academician Du was in a relaxed state.

There should be no problem.

But Du Yishan's next words made him feel like he was struck by lightning.

"Xiao Liu, I think Chang Haonan can come to me to study for graduate school. Well, like Xiao Yao, I can make an exception and let him directly study for a doctorate."

"what?"

Liu Hongbo looked confused.

Why is it that the student I just fell in love with in the morning will become my junior brother at noon?
