"Yes, he is. Boy, let me tell you, don't look at his young age, he is definitely no worse than you in this regard! "Bragging, anyone can.

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

"The teacher wrote to me at the end of last year, hoping that I could take care of you more. I've been asking you about that unit, and I thought it was on our side...... It seems that the teacher had already guessed that you would come to me to do this......" Yan Liben's attitude immediately changed one hundred and eighty degrees.

Brothers in the same sect naturally need to support each other.

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

"Don't call me senior, if you let the teacher know, you'll have to cramp and peel me. You don't know that you are the most proud disciple of the teacher, although you have only been with him for a year, but the teacher thinks that you have a stronger foundation in aerodynamics than us, and you are more talented in this area. I really didn't expect you to use this talent for this......" Yan Liben interrupted Liu Yijiu's words very dissatisfied.

Calling him a senior, isn't that scolding him?

"Senior brother, you're lifting me up. I don't have any talent for this, but it just took some more time......" Liu Yijiu saw that the three old men were all looking at him with complicated expressions, and he immediately regretted coming here.

Wang Shunyi and Qin Yuan's thoughts can be known without thinking about it, and it is estimated that he will not be relaxed after he goes back.

As for Fu Wei, don't think about it, this old man wanted to transfer him to Base 002 at the beginning, now that he knows his identity and his ability, will he let him go easily?

The design of long-range missiles and space rockets, these things are very much for the study of aerodynamics, there are not many young people in domestic aerodynamics, there is already a fault, even if there is no way to give Liu Yijiu any important position now, but wait a few years, it is absolutely possible, with a little training, in the future, it will also be the flag-carrying figure of their 002 base in this regard.

"Don't be modest, I guess the teacher has written to every student in the mountain, but no one knows which unit you are in. If there is anything you need, we are here to help. By the way, what exactly do you design rockets, and why do you think aerodynamic experiments are needed? Is it a long range? Yan Liben didn't say anything more.

The two were strangers before, even if they had a relationship with a teacher, they could get close all of a sudden, but there was not much possibility.

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

The 002 base of aerospace, regardless of whether it understands technology or not, knows the shape of rockets and missiles very clearly.

In particular, two sets of fins that stabilize the flight attitude, which appear only on missiles.

"Wang, are you sure you're designing rockets, not missiles?"

"Of course, I can't even tell the difference between missiles and rockets? Although I don't read much......"

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

"Senior brother, this is indeed a rocket, but the range is higher than that of ordinary rockets, with a minimum range of one hundred and twenty kilometers, of course, this is theoretical design data, what is the result, it needs to be tested after trial production...... Liu Yijiu saw Yan Liben's inquiring eyes and explained with a smile. As you know, this design will reduce the resistance to the air a lot, making the flight attitude more stable. There is nothing wrong with a rocket launcher with a short range, but this has a long range, so you have to consider these problems, if the air has too much influence on the flight process, it is very likely that the final impact point will be offset by several kilometers......"

The influence of aerodynamics on flying objects is very crucial, which is why wind tunnel tests exist.

When designing any aircraft, it needs to take this problem into account, and then continuously improve it in the process of trial production to make the flight attitude more stable.

"The teacher really didn't misunderstand you. You are more unconstrained and unconstrained than our thinking. Whether it's a rocket, or a missile, or whatever, no one has to use a certain form design, as long as you can get a more stable flight trajectory......" Yan Liben sighed.

Originally, the teacher praised Liu Yijiu very much in the letter, which made him feel that the teacher was very likely to be old, no matter how strong his talent was, it was impossible to be stronger than the third generation of international aerodynamics, right?

Now it seems that Liu Yijiu is likely to become the fourth generation head of this aspect.

The international situation may not make him recognized, at least, there should be no problem with the second-generation head of this area in China, and Liu Yijiu is still too young.

"Little junior 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, but now the wind tunnel experiment at the 002 base is doing a very important missile flight simulation experiment, which has been carried out for thousands of hours, and it will take longer to complete.

This can't be stopped.

"Senior brother, can you hurry up? This one of ours doesn't take up much space, and it can be blown along with your experimental items. Although this will have an impact on your experimental data, it will be possible to test the effect of high-speed flying objects on their flight trajectory when flying around. The high-speed camera inside the wind should be able to capture these. Of course, the trial production of our samples has not yet been completed, and it is estimated that it will take a month to manufacture them......" Liu Yijiu suggested.

He also knows that from the finalization of large missiles to the retirement of the final product model, wind tunnel experiments must be carried out. After the wind tunnel experiments, some improvements will be made to the product, resulting in some improved models.

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

"It's a new experimental project, so I'll think about it again." Yan Liben said with a frown. "How fast are your rockets designed to go?" You should know that the items we are experimenting with are now in the high-speed testing phase......"

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

"How much?"

"The muzzle velocity is 63 meters per second, and the Katyusha improved rocket engine can make this reach a flight speed of Mach 1.8, and after flying a certain distance, it will gain a higher ......speed under the effect of weight reduction and inertia," Qin Yuan exploded the flight speed of the rocket they designed.

Rocket artillery says flight speed, but it doesn't actually make sense.

Because this thing is usually about the initial velocity of the ejection from the launcher.

The reason why we want to study the speed of this aspect is because Wang Shunyi and others, and even Chen Hao, are all preparing to enter missile research. Rockets can be considered the basis of missiles. The more they research, the faster their research on missiles will progress.

"......" Yan Liben was speechless.

He didn't know what to say anymore.

He didn't know how to comment on these things, rockets are not missiles, and such a rate of fire is really a bit shocking. With a range of one hundred and twenty kilometers, an average flight time of twice the speed of sound, it will be possible to reach the target area in three minutes! How scary is that?

It's a shell, not a missile!

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

"Senior brother, thank you." Liu Yijiu's sentence of senior brother is from the bottom of his 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 amount of wind speed, what kind of effect it has on the rocket in flight, etc., are all reflected from these data.

"You're not going to leave tonight, are you? How about I'll treat you well then? Yan Liben asked at Liu Yijiu.

"Not 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 many things ...... our side" Before Liu Yijiu could answer, Wang Shunyi interjected.

Liu Yijiu was puzzled, didn't he originally say that he had to stay here for a few days? Why do you suddenly want to go back?

"That's okay, anyway, we are so close, we have technical cooperation, and there will be more opportunities in the future......" Yan Liben did not force it.

"Uncle Wang, is there a conflict between you and Mr. Fu?" On the way back, Liu Yijiu couldn't help but be a little curious when he saw Wang Shunyi, whose face had not become very good.

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

No wonder both of them kept sneering all afternoon.

"The space base is for the study of missiles, which is too simple. It's a lot freer than ours, so what's the point? I still like to be on our side, if you want to do a project, you can do any project......" Liu Yijiu hurriedly said.

For Base 002, he really didn't have any temptation.

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

"Doesn't he want to dig us, in return, he has to find a way to transfer Cao Zhijiang to our side......" Liu Yijiu is obsessed with Cao Zhijiang.
