Chapter 145 You Really Want Me to Pass
"Is there any news about the stealth fighter, or is it that the Jincheng Aircraft Design Institute wants to talk to me?"

Wednesday, February 2006, 2, Department of Engineering Mechanics, Qinghua University.

Xu Yuan stood outside Xu Chongxing's office, thinking about the reason why he suddenly came to find him this time, and raised his hand to knock on the office door.

The next second, a familiar voice was heard coming from inside.

"Please come in."

Xu Yuan pushed the door open and saw Xu Chongxing sitting in front of the computer working. He approached and took the initiative to greet him.

"Hello, Professor Xu."

"You haven't been here for a long time." Xu Chongxing raised his eyes and looked at Xu Yuan, and his tone was a little sour when he spoke: "Sit down first."

The main reason is that Xu Yuan is also a student in their Department of Engineering Mechanics, and he is clearly pursuing two professional degrees at the same time.

As a result, he now has a PhD in science and has a significant influence in the international mathematics community, but he is still an undergraduate in engineering. Although his grades are excellent, I still can't help but envy him.

Especially when he thought of Tang Shihong's recent smugness, he couldn't help feeling jealous.

After all, who doesn’t want to see their students succeed? At least it will make the teacher feel proud.

The key is that Xu Yuan’s talent in engineering subjects such as fluid mechanics and structural mechanics is no less than that in mathematics.

Otherwise, he would not have designed an aerodynamic layout plan in his freshman year, which not only made up for the shortcomings of the canard style, but also was used in the research and development of the appearance of the latest generation of domestic stealth fighter jets.

This contribution to the country alone is much greater than proving a mathematical conjecture.

The key domestically produced latest generation stealth fighter project is confidential, and no information is allowed to be leaked before the official first flight.

Under such circumstances, the outside world naturally did not know about Xu Yuan's talent in engineering.

In addition, Xu Yuan's proof of mathematical conjectures was also a glory for the country, so he didn't want Xu Yuan to focus too much on mechanics.

Besides, even if he was willing, the Academy of Mathematical Sciences would definitely not let him go so easily.

As a result, I haven't seen Xu Yuan much during this period.

Xu Yuan naturally wouldn't be polite with Xu Chongxing. He walked to the sofa next to him and sat down before responding with a smile.

"Isn't this a challenge given to me by Professor Qiu? I'm busy trying to find a way to prove Qiu Chengtong's conjecture, so I come here less often."

"But if I have nothing else to do, I will definitely come to your place more often."

Of course he knew what Xu Chongxing was thinking, so he made a special promise at the end.

When Xu Chongxing heard this, a smile immediately appeared on his face again, and then he personally poured a glass of water for Xu Yuan.

He handed it over and said, "I've been following your affairs. I didn't expect your mathematical talent is so abnormal. It has only been a short time and you have solved several difficult problems in the field of mathematics." He did not hesitate to praise Xu Yuan's mathematical knowledge.

"Maybe I have more inspiration than others." Xu Yuan quickly stood up and took the cup of water with both hands and said.

"You don't need to be modest. Having the inspiration to solve difficult problems is also part of your own strength." Xu Chongxing waved his hand to interrupt.

The two of them exchanged a few brief sentences, and Xu Chongxing then stated his purpose without further ado.

"I asked you to come here today because I want your help. Are you interested in listening?"

Although Xu Chongxing did not say the final word on the matter directly, but gave him the right to choose, Xu Yuan subconsciously thought of the matter at Jincheng Aircraft Design Institute after hearing it.

So he asked tentatively: "Is there something wrong with the stealth fighter?"

"It has nothing to do with Jincheng Research Institute. Since your aerodynamic layout and appearance design has been approved, there will be no problem." Xu Chongxing immediately explained when he saw Xu Yuan was distracted.

This made Xu Yuan even more confused.

Since Xu Chongxing asked him for help, it must be related to subjects such as fluid mechanics and structural mechanics.

If you want to make use of his mathematical knowledge, the person sitting in front of you should be Liao Fangyi or Tang Shihong.

But apart from the several aircraft design institutes under the Aviation Industry Corporation of China, he was not familiar with or had any contact with the others.

The thought stopped here, and he immediately asked: "Who wants me to help?"

"It's a project of the Space Technology Research Institute, which is about the design and development of the Chang'e-1 lunar exploration satellite."

"Space Technology Research Institute..."

"Chang'e 1?"

When Xu Yuan heard the key information from Xu Chongxing, he immediately fell into deep thought.

He is familiar with all of these. Among them, the Space Technology Research Institute was the one that developed and launched the first artificial satellite, Dongfanghong-1, which can be said to have ushered in a new era of national exploration of outer space.

Its research institute belongs to the China Aerospace Science and Technology Corporation.

It has also successfully achieved manned space flight, making the country the third country in the world to independently master manned space technology.

The Chang'e-1 lunar exploration satellite, as a lunar exploration project, will be a new milestone after artificial earth satellites and manned space flight.

Therefore, the Chang'e-1 lunar exploration project is considered a very important project of the China Aerospace Science and Technology Corporation.

After thinking about this, Xu Yuan couldn't help but feel puzzled. Logically speaking, he didn't have any achievements in mechanical engineering, so he shouldn't be chosen for such an important project as the lunar exploration project.

Feeling surprised, he still asked Xu Chongxing a few more questions.

"Professor Xu."

"What aspect of research will I be responsible for?" "Regarding the overall layout, mass distribution and appearance design of Chang'e-1, the main thing is to see if there is still room for optimization." Xu Chongxing explained in detail.

Xu Yuan is clear about the overall layout and mass distribution of the satellite, which is related to the attitude control of the satellite itself and is a very important function.

While the satellite is orbiting the moon, Chang'e-1 needs to maintain its orientation relative to the moon, the earth and the sun.

This is also to ensure that the data can be transmitted back to Earth.

In addition, the satellite’s solar panels must remain oriented toward the sun, which places higher demands on the satellite’s attitude control under three-vector control.

If the overall layout and mass distribution are not reasonable, problems are likely to occur during the lunar orbit.

It is right for the Space Technology Research Institute to maintain a rigorous attitude in this regard and continue to optimize the plan and fill in the gaps.

After figuring out the whole situation, Xu Yuan couldn't help but feel tempted. After all, this was his specialty.

It just so happens that there are no topics in mathematics at the moment, so it might be a good idea to go to the Space Technology Research Institute to gain some experience.

Just as Xu Yuan was thinking about this in his mind, Xu Chongxing's voice suddenly rang in his ears again.

"How are you thinking about it? Are you interested in participating?"

"Once this project is completed, it will count as your graduation thesis. How about you go straight to a doctorate in engineering?"

When Xu Yuan heard Xu Chongxing say this, he had no reason to hesitate, but he had to clarify one thing before agreeing.

"I can go over and help, but I want to confirm with you, Professor Xu, whether they really want me to participate in this project?"

When asked this question, Xu Chongxing was stunned for a moment, but quickly came to his senses and explained with a smile.

"The canard wing aerodynamic layout you designed was selected as the appearance design for the domestically produced stealth fighter, which shows that you have both high level and talent."

"With his mathematical prowess, he is the most suitable person to help."

"If you're willing, I'll contact Professor Chen, and you can just report there directly."

After listening to Xu Chongxing's words, Xu Yuan agreed after a slight hesitation.

"I would like to go."

"Then you should get ready and report tomorrow." Xu Chongxing immediately stood up and said happily after hearing that.

After things were settled, although Xu Yuan always felt something was wrong, he did not linger any longer. He said something to Xu Chongxing and turned around to leave for the dormitory.

Xu Chongxing stared at Xu Yuan's back until he completely disappeared from his sight.

The whole person sighed to himself thoughtfully: "I hope this project can help you."

From what he really thought, he didn't want Xu Yuan to devote all his energy and time to mathematics, because it would be a waste of his other talents.

Although the study of theoretical mathematics helps promote the progress of civilization, it does not play a substantial role in national development at this stage.

You must know that compared with the various advanced technologies possessed by overseas, our country still has a long way to go.

Therefore, he wanted Xu Yuan to demonstrate his mechanical skills more if there was a chance, so he specially found such a project.

-

Xu Yuan came out of Xu Chongxing's office and did not go back to the dormitory directly.

Instead, I turned into the library and borrowed some books about satellites and aerospace.

Since I have promised Xu Chongxing to help, I must be fully prepared.

Otherwise, if he performs poorly at the Space Technology Research Institute, he wouldn't be the only one to be embarrassed.

As for Li Zhenya and his roommates, although they will only officially enter their senior year and graduate in the second half of the year, they have already started to worry about their graduation thesis.

I have no idea about the topic of my thesis and don’t know how to choose it.

This is somewhat similar to when Xu Yuan was about to write his graduation thesis.

The only difference is that the difficulty of the subjects is huge.

The main thing was that the three of them reached a consensus that they would never rely on Xu Yuan until the last minute, and they were ready to complete this graduation thesis on their own to prove that their years of college study were not in vain.

Xu Yuan was naturally happy to see this situation, so he had no objection.

After returning to the dormitory with the books borrowed from the library, he saw Li Zhenya and the other three sitting in front of the computer. After giving them encouragement with his eyes, he sat at his desk and studied the relevant materials carefully.

Soon I was immersed in it and entered a state of deep learning.

Since Wang Haitao, Liu Yang and others didn't ask too many questions, he certainly wouldn't say anything on his own initiative.

Anyway, the Space Technology Research Institute is also in Yanjing, not particularly far from Qinghua.

that's it.

The next day, after breakfast, Xu Yuan called Chen Yuran and said that he was going to the Space Technology Research Institute and then left school.

Although he was no stranger to the Space Technology Research Institute, he still felt a little nervous after arriving safely.

After pacing around the door for a while, he took out his phone, found the number Xu Chongxing gave him, and called...
