Chapter 1: Rebirth in 1996, design a fighter jet! (New book request (page 1)

In a classroom at Beijing University of Aeronautics and Astronautics, Chang Haonan was sitting on a chair, looking blankly at a pile of aircraft design drawings spread out in front of him. I have three students who look like two boys and one girl.

"Am I not in Base 29 testing the JF-22 ultra-high-speed wind tunnel that will be put into use soon?" Chang Haonan thought to himself: "Where is this?"

The surrounding walls are slightly worn, and the bottom one meter near the ground is painted green, especially in areas that are often exposed to the sun.

Two huge ceiling fans were humming overhead, and there was no sign of air conditioning.

The blackboard next to it is actually a black cement board instead of the common green board made of epoxy resin and polymer alloy. It has turned white due to long-term use and wear. Even sitting in Chang Haonan's current position, he can see it. I don't know what's written on the side.

He was very sure that there was no such place in Base 29.

Chang Haonan's eyes quickly focused on the wooden desk in front of the blackboard. There was a school emblem hanging in front of the desk, which was a pattern he was very familiar with.

Beijing University of Aeronautics and Astronautics, my alma mater.

He raised his hand and pinched the right side of his face, then confirmed that this was not a dream.

"Haonan, Haonan?" One of the boys with a curly hair and a slightly fat figure leaned over and gently patted Chang Haonan on the shoulder.

"Are you okay? Why did your face turn so pale all of a sudden? And you've been stunned for five or six minutes since just now. If you find it too difficult, just say it, and the brothers won't laugh at you."

Chang Haonan turned his head to look at the other person, and it took him a few more seconds to find this face from distant memories.

"Old Wu?" Chang Haonan asked tentatively: "How come you..."

The person he just spoke to was his roommate when he was in college, named Wu Yifan. The two had different ambitions but had a good relationship. The latter went into the business world after graduation and gained a lot of money.

only……

What appeared in front of Chang Haonan was the image of Wu Yifan when he was young. At that time, his hair was still very thick, and there was no scar at the corner of his eye that was later cut out in retaliation by a competitor.

"Hey, Haonan, even if you really find it difficult, there's no need to pretend that you don't know Lao Wu. Even if we can't design a supersonic fighter, there's still no problem in designing a glider. There's no shame in it." Another tall and thin man said The boy showed a helpless smile: "And I think you should take a break. You've been staying up late these days, right?"

This sentence finally completely awakened Chang Haonan's memory of the scene in front of him.

"Don't worry, I'm fine." He took a deep breath, then looked down at the drawings on the table in front of him - it was a J-7, or to be more precise, it was the design drawing of the MiG-7, the imitation prototype of the J-21. .

This happened in the second semester of his junior year, that is, in the first half of 1996. He was greatly stimulated by the dispute between China and the United States at the beginning of the year, so he decided to study aircraft design, which accounted for 10 credits. In the course, an improved fighter jet was designed using the J-7 as a prototype.

The three people in front of him were classmates in the same course group as him.

Except for Wu Yifan, who is not interested in this major but is determined to go into business, the tall and thin man named Zhou Shuwan is the other big figure in the group besides himself, and his father is a senior researcher at the 601 Institute. This matter Only a few people know about it.

After Zhou Shuwan graduated, he also entered Institute 601, and later served as a designer of a certain type of carrier-based aircraft subsystem.

As for the girl who has never spoken, her name is Zhang Man. She is a petite, sweet and cute beauty with above-average academic performance.

Since Zhou Shuwan has always liked her, he decided to let her join the group. However, Zhang Man actually had no feelings for Zhou Shuwan and just kept holding the latter's thigh. He got high marks in all experimental courses and group assignments, but Chang Haonan was not familiar with her, and they lost contact after graduation.

Such a group actually only has 2.5 people, but now that the team formation stage is over, it is no longer possible to randomly replace people.

Regarding Chang Haonan's idea of ​​designing a supersonic fighter jet, the three of them naturally felt that it was completely impossible.

They did not object directly, but found the design drawings of the J-7 prototype MiG-21, saying that since they wanted to improve, they should at least fully understand the design prototype.

If Chang Haonan can calculate the aerodynamic performance of the MiG-21, then they agree to accompany him to continue the adventure. If not, then follow Zhou Shuwan's idea to design a glider with a large aspect ratio.

Is it just the result... After all, people have their limits. For Chang Haonan, whose talents on the original timeline are generally just hard work, this matter is indeed beyond his ability.

In the end, he had no choice but to design a glider with three other people as agreed. Although he got a good score in this course, it has become a regret that Chang Haonan has always had.

As for the current situation, he should have returned to his college days nearly 30 years ago, and it happened to be at this critical moment.

Calculating the performance of the MiG-21 is not a problem at all for Chang Haonan now.

Because in addition to the work experience from later generations, the moment Chang Haonan saw the full design drawings, a [scientific research guidance system] suddenly appeared in his mind.

After he comes up with a reasonable and closed-loop project idea, the system can spend a certain amount of [scientific research points] to determine what to do and how to do it in each next step, and give him the corresponding capabilities.

Simply put, this system is equivalent to a tutor who is responsive and provides guidance.

The moment he saw this system, Chang Haonan almost fainted with excitement - after all, everyone who has studied for a graduate degree hopes to have such a mentor.

Of course, if 10 times the scientific research points are consumed, the system can directly give the correct or optimal result, but as someone who has actually led a project, Chang Haonan knows very well that this is by no means the most efficient way to use it.

It also takes time and energy to transform the results in his mind into reality. Even if he stays awake, he will not be able to output many specific scientific research results. Moreover, the system's scientific research points probably do not support such a squandering.

More importantly, he is not the only scientific researcher in China.

If you can drive the efficiency of the entire Chinese scientific research system by solving key problems or providing methodologies with the help of a super mentor like the system, then the power you can unleash will be hundreds of times greater than if you were alone.

However, it was too far to talk about this in Chang Haonan's current state, so he decided to redeem his past regrets first.

[Research points: 10

The ability value level is not high.

But this is actually a good thing.

This shows that for the system, the knowledge Chang Haonan mastered before his rebirth was very rudimentary.
