Chapter 1: Rebirth in 1996, design a fighter jet! (New book to follow)
In a classroom at Beijing University of Aeronautics and Astronautics, Chang Haonan was sitting on a chair, looking blankly at the pile of aircraft design drawings spread out in front of him, as well as his clothes. There were three students, two men and one woman, who looked very contemporary and looked at him with concern.
“I’m not testing the JF-22 ultra-high-speed wind tunnel that will be put into use soon in Base 29?” Chang Haonan thought to himself: “Where is this?”
All around The 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 overhead were humming, 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 badge hanging in front of the desk, which was a pattern that 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 suddenly turn white as if something? And you have been stunned for five or six minutes just now. If you find it too difficult, just say it. Brothers won't laugh. Yours."
Chang Haonan turned his head to look at the other person, and it took him a few more seconds to find this face in his 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 ambition between the two They are different but have a good relationship. After graduation, the latter entered the business world and gained a lot of money.
It’s just...
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 find it really 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. "The other tall and thin boy showed a helpless smile: "And I think you should take a break. You have stayed up late these days, right?"
This sentence finally fully awakened Chang Haonan about the scene in front of him. Memories of scenes.
"Don't worry, I'm fine." He took a deep breath, and then looked down at the drawings on the table in front of him - it was a J-7, or to be more precise, a replica prototype of the J-7 MiG-21 design drawing.
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 are 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 from the 601 Institute A senior researcher, only a few people know about this matter.
After graduating, Zhou Shuwan 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 impossible to replace them casually.
As for Chang Haonan's idea of designing a supersonic fighter, the three people naturally felt that it was completely impossible.
They did not object directly. They just found the design drawings of the J-7 prototype MiG-21 and said that since they want 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 large aspect ratio aircraft. glider.
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 this course got a good score in the end, 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 complete 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 and guidance.
The moment he saw this system, Chang Haonan almost fainted with excitement - after all, everyone who has studied for graduate school hopes to have such a mentor.
Of course, if 10 times the scientific research points are consumed, the system can also 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 efficient. Highest usage.
Translating the results in his mind into reality also takes time and energy. 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 is too far to talk about this in Chang Haonan's current state, so he decided to redeem his past regrets first.
[Scientific research points: 10
Theoretical level (full level LV5): LV2 (0/10000)
Engineering experience (full level LV5): LV1 (0/1000) Management ability (full level LV5): LV0 (0/100)
Comprehensive ability: LV1
Projects in progress: 0
Projects that can be carried out: 1]
The ability value level is not high.
But this is a good thing.
Explanation that for the system, the knowledge Chang Haonan mastered before his rebirth was very rudimentary.
The levels here are obviously based on the upper limit that humans can reach, not on the current era.
In other words, the future is promising!
...
Looking at the system panel, a bold idea appeared in his mind.
Although he himself knows that it is not reliable.
But now that we have the system, we have to give it a try after all...
“Design me a J-20!”
Don’t worry about whether China could build the J-20 in 1996, just say whether it’s handsome or not!
Stealth, canards, dual-engine heavy combat, DSI air intake, active phased array radar...
You must know that the YF22 has not completed its test flight at this time!
However, Chang Haonan's sexual intercourse was poured cold water on him not long after he started.
[Insufficient ability level and no available ideas for this project]
...
Obviously, his idea about the J-20 is just an idea at best, and it completely fails to meet the "reasonable and closed-loop project concept" required by the system.
It makes sense to think about it, just like a student who has just entered graduate school and asked his instructor to teach him to design a fifth-generation fighter jet. Obviously, he is still slightly lacking in ability and experience.
“We still have to modify the MiG-21 based on the existing equipment...” Chang Haonan had no choice but to return his attention to the MiG-21 design drawing in front of him.
The system now only has 10 scientific research points, and it must not be used indiscriminately. There are indeed many deeply improved models of the MiG-21 in later generations, but some of these designs require a lot of computational simulation work, and Chang Haonan does not He knows which plan can be implemented based on the scientific research conditions in 1996 and his current abilities.
Therefore, the ideas of Zhou Shuwan and three others are actually correct. It is better to understand the MiG-21 first, and by the way, check the hardware level of Beijing University of Aeronautics and Astronautics in the mid-1990s.
“Use CATIA to model the MiG-21, and then use the finite volume method to simulate the aerodynamic characteristics of the aircraft.” Chang Haonan thought silently in his heart.
[Technology points consumed to improve the project: 1 point, points consumed to directly give the project results: 10 points. Are you sure to carry out the MiG-21 modeling and simulation project? 】
Chang Haonan took a deep breath and clenched his fists suddenly.
It’s done!
"Confirm! Improve the project!"
A large amount of information quickly poured into his mind. Although he still didn't know what the result of this problem was, at least he already knew what should be done next and how to do it.
That's it, I understand it completely.jpg
After another half minute of silence, Chang Haonan spoke again: "I have thought of a way. Believe me, even if we are fighter jets, we can It can be designed.”
“Haonan, do you really have an idea?”
Zhang Man placed an enamel cup filled with hot water on the table in front of Chang Haonan and asked with a slightly skeptical tone.
On the side of the enamel cup is an air force emblem and an inscription from the instructor: "Establish a strong people's air force to defend the motherland and prepare to defeat the invaders."
This is Chang Haonan's special request. My father got it and has been carrying it with me ever since that incident and has been using it for many years.
As a person whose main goal is just to get high scores, Zhang Man naturally felt that the idea of designing a fighter jet was a fantasy from the beginning, but after all, Chang Haonan's usual grades are considered among the best, and the course design work The latter's contribution is indispensable, and she doesn't want to make the relationship too tense by directly objecting.
That’s why I came up with the idea of asking Chang Haonan to analyze the aerodynamic characteristics of the MiG-21, hoping to make the other party retreat in spite of difficulties.
There is no exam in this course, and the course design assignment will directly affect their final grade, and she doesn't want to go crazy with it.
"Thank you..." Chang Haonan picked up the cup and drank the water in it. Then he directly grabbed the design drawing of the MiG-21, folded it and put it in the bag next to him.
“Let’s go to the computer room!”
