The military-industrial scientific research system of the academic master

The other three people looked at Chang Haonan with his fists clenched. Of course they knew that the latter decided to make his coursework more difficult because of this incident.

What they didn't know was that Chang Haonan almost became an air force pilot, but during the physical examination, he was found to have bad teeth and was rejected.

"But Haonan, if this is the case, it is not just an aircraft design issue." Zhou Shuwan has been influenced by it at home since he was a child, and he understands nature more than others: "Based on the existing mature technology, we must also consider production Manufacturing issues, but we are still college students after all, and we have no way of knowing what the specific level of my country’s current aviation manufacturing technology is?”

Chang Haonan looked at Zhou Shuwan next to him and stood in front of the desk with his hands behind his hands: "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 the FC1 Xiaolong fighter derived from the modified "Super 7" project. This aircraft was completely unrecognizable in appearance. There is no shadow of the original model.

But after seeing the true performance of computers in this era yesterday, he realized that without supercomputing resources, it would be extremely difficult to design the DSI air inlet with an ordinary PC. Needless to say, other parts of the body have also been greatly modified.

And the best aviation engine that can be independently produced in China at the moment 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, 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 remembered that the teacher of his course was named Liu Hongbo. He was a very young professor. Shortly after the start of the next semester, he was seconded to participate in the airworthiness certification and technical improvement work of Y7-200A, which was later the MA60 passenger aircraft. .

The time was just after the end of their graduate student promotion process.

Therefore, 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 a lot of material.

"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 three-dimensional view of the J-7E and placed it 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 with his peripheral vision.

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, the intake nose cone is increased, and a radar is installed inside. However, The price is that 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, coupled with the current radar The technology is definitely stronger than it was back then, and 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.

Therefore, 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. Choosing this option really looks down on us. 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 got involved in the recognition of Chang Haonan's ability, so he was embarrassed on the spot and looked at Zhang Haonan. Man, then looked at Chang Haonan who frowned slightly next to him.

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 she showed that she would take the initiative to help you with things. I don't mean to stand by and watch.

But her subsequent words and deeds quickly destroyed the positive image she had finally built up in Chang Haonan's mind.

You should know that although this big assignment is a group of four people, when it comes to grading, not everyone in the group will get the same grade. Instead, the group assignment will be graded based on the contribution of each member to the work. float.

Chang Haonan, who has been identified as the big player, and Wu Yifan, who is already ready to paddle and does not care about the results, naturally rank at the top and bottom of the contribution rankings. Therefore, the only room for discussion is who ranks between Zhang Man and Zhou Shuwan. two.

Whether it's flattering or charming, these are all part of a person's abilities. Chang Haonan himself is not good at this, but he will never look down on people who are good at it. As for the emotional problems between Zhou Shuwan and Zhang Man, that has nothing to do with him. It’s okay to be 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.
