Super military empire

"Yes, he is. Boy, let me tell you, don't look at his young age, he is definitely not worse than you in this respect!" Bragging, anyone can.

Especially Qin Yuan, for Liu Yijiu now has a blind faith.

"The teacher wrote to me at the end of last year, hoping that I can take care of you a lot. I have been inquiring about where you are in the unit, and thought it was our side...it seems that the teacher had long since guessed that you would come to me for work. This matter..." Yan Liben's attitude immediately changed one hundred and eighty degrees.

Brothers from the same discipline naturally need to support each other.

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

"Don't call me senior. If you let the teacher know, you have to skin me cramps. Don't you know, you are the teacher's most proud disciple. Although you have only been with him for a year, the teacher thinks you are better than us. The foundation of aerodynamics is more solid, and there is more talent in this area. I really didn't expect that you would use this talent..." Yan Liben interrupted Liu Yijiu dissatisfied.

Call him senior, isn't this scolding him.

"Brother, you praise me. I don't have any talent for this, but it took a little longer..." Liu Yijiu saw the three old men looking at him with complex expressions, and suddenly regretted. Here it is.

The thoughts of Wang Shunyi and Qin Yuan can be known without even thinking about it. I guess he won't be able to relax after returning.

As for Fu Wei, don't think too much. This old man wanted to transfer him to 002 base at the beginning. Now that he knows his identity and knows his abilities, will he easily let it go?

Designing long-range missiles, space rockets, these things have a lot of research on aerodynamics. There are not many young people in aerodynamics in China. There are already faults. Even if there is no way to give Liu Yijiu any important position, wait A few years, absolutely possible, with a little training, in the future, they will also be the flag bearers of their 002 base.

"Don't be humble, I guess the teacher has written a letter to every student in the mountain, but no one knows which unit you are in. If there is any need, we will do our best to help. By the way, what kind of rocket do you design? Yes, why do you think it is necessary to conduct aerodynamic experiments? Is it a long range?" Yan Liben said nothing.

The two were originally strangers before, and even if they had a relationship with a teacher, they were able to get close at once, but there was not much possibility.

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

Aerospace's 002 base, whether you understand technology or not, knows the shape of rockets and missiles very well.

Especially the two sets of fins for stable flight attitude, which only appear on missiles.

"Pharaoh, are you sure that you are designing rockets, not missiles?"

"Of course, I can't even distinguish missiles from rockets? Although I don't read much..."

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

"Brother, this is indeed a rocket, but it has a higher range than ordinary rockets, with a minimum range of 120 kilometers. Of course, this is theoretical design data. What is the result? It needs to be tested after trial production..." Liu Yijiu Seeing Yan Liben's questioning eyes, he explained with a smile."You also know that this kind of shape design will reduce the resistance to the air a lot, making the flight attitude more stable. There is no problem with the rocket launcher with a short range, but this has a longer range, and you have to consider these issues. If the air affects the flight process Too big, it is very likely that the final impact point will be offset by several kilometers..."

The impact of aerodynamics on flying objects is very critical, which is 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 really did not misunderstand you. You are more free from limitations and constraints than our thinking. Whether it is a rocket, a missile, or whatever, no one stipulates that a certain shape design must be used, as long as a more stable flight trajectory can be obtained. , That's it..." Yan Liben sighed.

Originally, the teacher praised Liu Yijiu very much in his letter, making him feel that the teacher is likely to be old, no matter how strong the talent is, it is impossible to be better than the third-generation head of international aerodynamics.

It now appears that Liu Yijiu is likely to become the fourth-generation leader in this area.

The international situation may prevent him from being recognized. At least, there should be no problem with the second-generation head of this aspect in China. Liu Yijiu is still too young.

"Little brother, I can help you arrange the plan in this regard, but we need to wait until our current experimental stage is completed..." Although it was brought out by a teacher, although the teacher has explained, the wind tunnel experiment of the 002 base is currently being done A very important missile flight simulation experiment has been carried out for thousands of hours, and it will take longer to complete.

This certainly cannot be stopped.

"Brother, can you hurry up? Our space that doesn’t take up too much can be blown with your experimental objects. Although this will have a certain impact on your experimental data, you can test that there are objects flying at high speeds. The impact on the flight trajectory when flying around. The high-speed camera in the wind should be able to capture these. Of course, our sample trial production has not been completed yet, and it is estimated that it will take a month before it is manufactured..." Liu Yijiu suggested .

He also knows that from the finalization of the large-scale missile to the final retirement of this product model, wind tunnel experiments have to be carried out.After the wind tunnel experiment, some improvements will be made to the product, resulting in some improved models.

Their rocket requirements are not as high as strategic missiles and space rockets.

"This is a new experimental project, I will think about it again." Yan Liben frowned and said."How high is your rocket design speed? You should know that the items we are experimenting with have now entered the high-speed experiment stage..."

"You can conduct high-speed experiments first, then medium-speed and low-speed experiments. I don't think low speeds are even necessary. Our rockets are designed to have a higher speed...

"How many?"

"The initial speed is 63 meters per second. Katyusha's improved rocket engine can achieve a flying speed of Mach 1.8. After flying for a certain distance, it will achieve a higher speed due to weight reduction and inertia..." Qin Yuan It broke the speed of the rocket they designed.

Rocket launchers say that the speed of flight is meaningless.

Because this thing generally refers to the initial velocity of ejection from the launcher.

The reason for studying the speed in this area 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, the faster their research progress on missiles.

"..." Yan Liben was speechless.

He didn't know what else to say.

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

This is a shell, not a missile!

"Okay, let me think about it again. You give me the content and technical requirements for the wind tunnel test. I will prepare in advance. After this experiment is over, let me do your experiment first. After the sample production is over, Just transport it to our side..." Yan Liben thought for a while, and after asking Fu Wei, he said to Liu Yijiu.

"Brother, thank you." Brother Liu Yijiu's sentence came from the heart.

Since Yan Liben agreed, he would definitely not deal with them.Especially let them give out the test items and content, which shows that he will really help seriously.The test of each project needs to obtain relevant data!The wind speed, what kind of impact it has on the rocket in flight, etc., are all reflected from these data.

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

"It won't work tonight. We'll have to rush back in a while. It's not easy to walk in the dark on such a long mountain road. What's more, there are a lot of things on our side..." Before Liu Yijiu answered, Wang Shunyi interjected.

Liu Yijiu was puzzled, didn't he mean to stay here for several days?Why are you going back suddenly?

"Well, anyway, we are so close, with technical cooperation, there will be more opportunities in the future..." Yan Liben did not insist.

"Uncle Wang, there is a contradiction between you and Mr. Fu?" On the way back, Liu Yijiu saw Wang Shunyi whose complexion had become bad, and couldn't help being a little curious.

"Nothing before, we started to have it today. Comrade Xiao Liu, you said that if we dig Cao Zhijiang in front of Fu Wei, even if that person is not important to them, what would you think of you as a manager?" Qin Yuan explained. Liu Yijiu understood.

It's no wonder that both of them have been cynicism all afternoon.

"The space base is for missile research. It's too single. Although it is much more free than ours, what's the point of this? I still like to be on ours. If you want to start a life project, you can do whatever project..." Liu Yijiu hurriedly Express your opinion.

For 002 base, he is really not tempted.

The Ninth Academy Base has been very indulgent to him from the beginning, and can do projects according to his own ideas.This is the most important for researchers.

"Didn't he want to dig us? In return, he must find a way to transfer Cao Zhijiang to our side..." Liu Yijiu never forgets Cao Zhijiang.
