Chapter 6 Aren’t you bullying an honest person?
The other three people looked at Chang Haonan, who clenched his fists. Of course they knew that the latter decided to make it difficult for himself in the coursework precisely because of this incident.
What they didn’t know was that Chang Haonan almost became an air force pilot, but during the physical examination, it was found that his teeth had a bad bite and he was rejected.
"But Haonan, if this is the case, it is not just an aircraft design problem." Zhou Shuwan has been exposed to it at home since he was a child, and he understands nature more than others: "Based on the existing mature technology, We also need to consider production and manufacturing issues, but we are still college students after all, and we have no way of knowing what the current level of aviation manufacturing technology in our country is."
Chang Haonan looked at Zhou Shuwan next to him? , standing in front of the desk with his hands behind his back: "From the beginning, I was not prepared to just make a design that could not be implemented."
According to common sense, Zhou Shuwan's words are certainly correct.
However, as a person who was reborn more than twenty years later, he himself went beyond common sense.
In fact, at the very beginning, when it came to improving the J-7, the first thing Chang Haonan thought of was naturally the FC1 Xiaolong fighter derived from the modified "Super 7" project. This aircraft was originally There is absolutely no trace of the original model in appearance.
But after seeing the real performance of computers in this era yesterday, he realized that without supercomputing resources, he would have to rely on an ordinary PC to design the DSI air inlet. It's hard to compare to the sky, let alone other parts of the machine that have also been greatly modified.
And currently the best aviation engine that can be independently produced in China is the turbojet 13F, which is really not enough to propel a third-generation fighter jet.
There is no way, the food must be eaten one bite at a time, and the scientific research must be done step by step.
The development of the aviation industry is not an overnight process. As he is still an undergraduate student, he has limited resources and cannot maximize the efficiency of the system.
At the same point in time in the previous life, Chang Haonan's ambition was indeed to design a model that could equip the People's Air Force to improve its combat effectiveness.
But now that he has been resurrected and even has the help of the system, this J-7 improvement plan is of greater significance to him as a stepping stone.
A stepping stone to a wider world.
Therefore, in addition to showing a certain degree of advancement, the design plan must also be short, fast, and down-to-earth enough to be completed within the time specified in the course design assignment, and reflect one's current overall understanding of the development of the aviation industry.
Chang Haonan remembers that the teacher of his course was named Liu Hongbo. He was a very young professor who was seconded shortly after the start of the next semester to participate in the airworthiness of the Y7-200A, which was later the MA60 passenger aircraft. Validation and technical improvement work has gone on.
The time is just after the end of their graduate student promotion process.
So many of Professor Liu’s students also directly or indirectly participated in related work.
They are all opportunities.
What Chang Haonan needs most now is exactly this kind of opportunity.
After determining the basic principles of the improvement plan, Zhang Man was the first to speak.
"Brother Nan, I just checked some existing ideas for improving the MiG-21 or J-7 in the library." Zhang Man said, putting his schoolbag and cloth bag on the table, and then took out some A lot of information came out. "The first is the improvement plan our country has already had, which is to replace the large delta wing of the MiG-21 with a double delta wing, reduce the average chord length of the wing, increase the aspect ratio, and focus on improving the aircraft's mid- and low-altitude maneuverability. However, because The air intake has not been improved, so the nose cone still does not have enough space to accommodate the radar, so let alone beyond visual range, it does not even have all-weather combat capabilities."
Zhang Man pulled out a J-Fighter. The three views of 7E were placed in front of Chang Haonan - it was active equipment after all, and detailed design drawings were unavailable. Then he secretly glanced at the latter's expression from the corner of his eye.
After discovering that there were no changes, Zhang Man decisively pushed the drawing aside and took out another piece of information. This one was much more detailed and even contained a lot of specific data.
“The second one is the MiG Design Bureau’s own improvement, that is, the MiG 21MF and MiG 21 Bis. While the overall aerodynamic layout remains unchanged, the body is enlarged and the intake nose cone is enlarged. Install a radar inside, but the cost is that the maneuverability will be greatly reduced."
"I think this idea is good."
Zhou Shuwan stood up and looked at the drawings on the table. .
“In the late 1980s, we also designed a J-7C with a similar idea, but in the end only a dozen were produced. I think we can improve it on this basis and further increase the size of the nose cone. In addition, today’s radar technology is definitely better than that of the past, so it is even possible to launch radar-guided air-to-air missiles like the PL-4.”
In 1996, the Thunderbolt 4 had already been discontinued, and the Thunderbolt 11 was still in the difficult process of imitation. However, this did not prevent students from the Aeronautical and Astronautical University from dreaming of a new weapon with a longer range.
However, Zhang Man next to him confirmed through Chang Haonan's expression that this was not the idea that the other party wanted when the latter was only halfway through speaking.
So as soon as Zhou Shuwan finished speaking, she immediately expressed the opposite opinion: "I think this is not in line with the idea that Brother Nan just put forward. There are too few changes to the aircraft. Choose This plan really looks down on our brother Nan’s ability.”
And Zhou Shuwan, who was still in high spirits just now, was directly denied by his goddess without any shame, and even talked about Chang Haonan’s ability. He looked at Zhang Man and then at Chang Haonan, who was frowning slightly.
Originally, when Zhang Man took out a lot of information and started sorting out his ideas, Chang Haonan's impression of her had actually improved greatly. Not to mention whether it was useful, but at least it showed. It means taking the initiative to help you rather than just sitting back and watching.
But her subsequent words and deeds quickly destroyed the positive image she had finally built up in Chang Haonan's mind.
You must know that although this big assignment is for a group of four, when grading, not everyone in the group will get the same grade. Instead, the group assignment will be based on the contribution of each member to the work. Ratings vary based on the rating.
Chang Haonan, who has been identified as the thigh, and Wu Yifan, who is already preparing to paddle and does not care about the results, naturally rank at the top and bottom of the contribution rankings. Therefore, currently only Zhang Man and Zhou are left with room for discussion. Shuwan, who is ranked second?
Whether it’s flattering or charming, these are all part of a person’s ability. Chang Haonan himself is not good at this, but he will never look down on people who are good at it. As for the relationship between Zhou Shuwan and Zhang Man The problem has nothing to do with him being an outsider.
But while Zhang Man was flattering him by observing his words, he also didn't forget to step on Zhou Shuwan secretly. This nature was different.
If Chang Haonan directly agreed with Zhang Man's idea at this time, it would be equivalent to being used as a spearman by the latter.
It is true that Zhou Shuwan is an honest person, but an honest person cannot be bullied like this.
This will affect unity.
