"Yes, he is. boy, I'll tell you, don't look like he is young, he is definitely not worse than you in this regard!" He can brag, anyone can do it.

Especially Qin Yuan, he has begun to have a blind confidence in Liu Yijiu.

"The teacher wrote to me at the end of last year, hoping that I could take care of you more. I have been asking about which unit you are in, and I thought I was here with us... It seems that the teacher had guessed that you would come to me to do this..." Yan Liben's attitude immediately changed by 180 degrees.

Brothers and sisters naturally need to support each other.

"Senior, please ask you to..." Liu Yijiu didn't know how to deal with such enthusiasm.

"Don't call me senior. If the teacher knows, I have to cramp and peel me. You don't know that you are the teacher's most proud disciple. Although you have only been with him for a year, the teacher thinks that you have a stronger foundation in aerodynamics and have more talent in this area than us. I really didn't expect that you would use this talent to this..." Yan Liben interrupted Liu Yijiu's words with dissatisfaction.

Call him a senior, isn’t this scolding him?

"Senior Brother, you are polite me. I don't have any talent for this, but I just spent some more time..." Liu Yijiu saw the three old men looking at him with complicated expressions, and immediately regretted coming here.

Wang Shunyi and Qin Yuan can know everything they think without thinking. I guess he won’t be able to relax after he goes back.

As for Fu Wei, there is no need to think too much. The old man wanted to transfer him to base 002 at the beginning. Will he let him go if he knows his identity and his abilities now?

Designing long-range missiles and cosmic rockets, these things have a lot of research on aerodynamics. There are not many young people in China who have aerodynamics and have already broken down. Even if there is no way to give Liu Yijiu any important position now, it will definitely be possible to wait a few years. With a little training, they will be the flagship figure in their 002 base in the future.

"Don't be humble. I guess the teacher has written a letter to every student in the mountains, but no one knows which unit you are in. If you need it, we will help you with all our help. By the way, what exactly is the rocket you designed? Why do you think you need to conduct aerodynamic experiments? Does the range are very long?" Yan Liben didn't say anything else.

The two of them were strangers before, and even if they were in a teacher's relationship, they could get very close all of a sudden, so there was no possibility.

"What? You are clearly missiles, where is a rocket?" After entering his office, Yan Liben was speechless when he saw the appearance drawings taken out by Wang Shunyi, and Fu Wei reacted even more.

The 002 base of space is very clear about whether you understand technology or not, you still know the appearance of rockets and missiles.

Especially the two sets of wings with stable flight attitudes, which only appear on missiles.

"Lao Wang, are you sure you designed rockets, not missiles?"

"Of course I'm sure, can't I even distinguish between missiles and rockets? Although I don't read much..."

"..." Fu Wei had nothing to say.

"Senior brother, this is indeed a rocket, but this range is higher than that of an ordinary rocket, with a minimum range of 120 kilometers. Of course, this is theoretical design data. What is the result? It needs to be tested and tested..." Liu Yijiu saw Yan Liben's inquiring eyes and explained with a smile. "You also know that such an appearance design will reduce the resistance of the air a lot, making the flight attitude more stable. There is no problem with rocket launchers with a short range, but the range is relatively long. These issues have to be considered. If the air has too much impact on the flight process, it is very likely that the final bounce point will be offset by several kilometers..."

The impact of aerodynamics on flying objects is very critical, and this is also the reason why wind tunnel tests exist.

When designing any aircraft, this issue needs to be considered, and then continuously improved during the trial production process to make the flight attitude more stable.

"The teacher is indeed not wrong with you. You are more unlimited and restricted than our thinking. Whether it is a rocket, a missile, or something else, no one stipulates that a certain appearance design must be used. As long as you can obtain a more stable flight trajectory, it's fine..." Yan Liben sighed.

Originally, the teacher praised Liu Yijiu very much in his letter, which made him feel that the teacher is likely to be old. No matter how talented he is, he cannot be stronger than the third-generation head of international aerodynamics, right?

Now it seems that Liu Yijiu is likely to become the fourth generation leader in this field.

The international situation may make him unable to be recognized. At least, there should be no problem with the second generation of leaders in this field in China. Liu Yijiu is still too young now.

"My junior brother, I can help you plan this aspect, but we need to wait until our current experimental stage is completed..." Although it was brought by a teacher and although the teacher gave an explanation, the wind tunnel experiment at the 002 base is now conducting a very important missile simulation flight experiment. It has been conducted for thousands of hours and it will take longer to complete it.

This is definitely not something that can be stopped.

"Senior brother, can we be faster? Our place that does not occupy too much can be blown with your experimental items. Although this has a certain impact on your experimental data, it can be tested to see the impact of high-speed flying items on the flight trajectory when flying around. The high-speed camera inside the wind should be able to capture these. Of course, our sample trial production has not been completed yet, and it will probably take one month to manufacture it..." Liu Yijiu suggested.

He also knew that from the finalization of the large missile to the final retirement of this product model, wind tunnel experiments must be carried out. After the wind tunnel experiment, some improvements will be made to the product, thus giving birth to some improved models.

Their rockets do not require as high as strategic missiles and space rockets.

"This is a new experimental project, let me think about it again." Yan Liben said with a frown. "How fast is your rocket designed to be? You should know that the items we are experimenting with have now entered the high-speed experimental stage..."

"We can conduct high-speed experiments first, and then medium-speed and low-speed experiments. I think low-speed is not even necessary. Our rocket design is relatively high..."

"How many?"

"The initial speed is 63 meters per second, Katyusha's improved rocket engine can make this flight speed reach Mach 1.8. After flying for a period of time, it will obtain a higher speed under the influence of weight reduction and inertia..." Qin Yuan burst out the flight speed of the rocket they designed.

Rocket launchers say that they fly at speed is meaningless.

Because this thing usually refers to the initial speed ejected from the launcher.

The reason why we need to study this aspect is that Wang Shunyi and others, and even Chen Hao, are preparing to enter missile research together. Rockets can be regarded as the basis of missiles. The more research they have, the faster their research progress in missiles will be.

"..." Yan Liben was speechless.

He didn't know what to say.

He didn't know how to comment on these things. Rockets are not missiles. Such shooting speed is really shocking. A range of 120 kilometers, an average flight time of twice the speed of sound, can reach the target area in three minutes! How scary is this?

This is a shell, not a missile!

"Okay, I'll think about it again. You give me the content and technical requirements of the wind tunnel experiment test. I'll prepare in advance. After this experiment is over, I'll do your experiment first. After the sample production is over, it will be shipped to us..." Yan Liben thought for a while, asked Fu Wei before saying to Liu Yijiu and others.

"Senior brother, thank you." Liu Yijiu's words come from the heart.

Since Yan Liben agreed, he would definitely not deal with them. Especially when he asked them to give the test items and content, this means that he would really help seriously. The tests of each project require relevant data! The wind speed, what impact it has on the rockets in flight, etc. are all reflected from these data.

"You won't leave tonight, are you? I'll treat you well then, how about?" Yan Liben asked Liu Yijiu.

"It's not possible tonight. We will have to rush back later. It's hard to walk in the dark on such a long mountain road. What's more, there are many things to do there..." Before Liu Yijiu could answer, Wang Shunyi interrupted.

Liu Yijiu was puzzled. Didn’t he say he had to stay here for several days? Why did he suddenly go back?

"Okay, anyway, we are so close and have technical cooperation, so there are many opportunities in the future..." Yan Liben did not force it.

"Uncle Wang, do you have any conflicts with Mr. Fu?" On the way back, Liu Yijiu couldn't help but feel curious when he saw Wang Shunyi, who had become unsatisfied.

"Not before, but it starts today. Comrade Liu, what would you think if we dig Cao Zhijiang in front of Fu Wei, even if that person is not very important to them, you are the manager?" Qin Yuan's explanation made Liu Yijiu understand.

No wonder both of them kept sarcastic about the whole afternoon.

"The space base is just a researcher of missiles, which is too single. Although it is much freer than ours, what's the point? I still like to be with us. If you want to do a child project, you can do any project..." Liu Yijiu quickly made a statement.

He was really not moved by the 002 base.

The Ninth Hospital Base has been very indulgent to him from the beginning and can carry out projects according to his own ideas. This is the most important thing for researchers.
