Super military empire

(For the local tycoon Torrey of the Bay, that is, the leader-Xiaoding-greatly increased 1/25)

"Welcome Director Liu to inspect the work..." When Liu Yijiu followed Long Yaohua to the Aerospace Department, a group of big men came to shake hands with Director Liu, and some even joked like this.

"Director Du, aren't you a shameless kid!" Liu Yijiu's face was flushed, but he felt that his face was thicker than the inversion of the city wall, and he could even defend against a nuclear bomb attack. The big guys of the Aerospace Department couldn't resist a joke."If I let my father Qian know, don't interrupt my leg!"

"Minister Qian won't do it. You are our God of Wealth! This time we have to send funds to us again, it is too late to welcome..."

"Okay, let's go into the conference room and talk more!" Long Yaohua was a little bit dumbfounded. Now the people of the Ministry of Aerospace Industry are more enthusiastic about Liu Yijiu than the officials of the Ministry of Finance.

After some greetings, Liu Yijiu saw Qian Xuesen smiling at him, and even Du Bin, the instructor who led him into the aerospace field.

Several bigwigs of the Beidou system are also here, which shows that the Ministry of Aerospace Industry attaches great importance to his trip.

"This time, I think everyone already knows something. The Ministry of Aerospace and the Ninth Academy have not cooperated once or twice. Now both of you have long-term and stable cooperation, so there is no need to introduce it. "Long Yaohua presided over the meeting. After everyone was seated, he said, "This time, it involves the country’s most secret project, Dongfeng-31. At present, this project is still in the stage of theoretical research. The ballistic missile business is not very familiar, but there is still strong technical strength in some related technologies. More importantly, the Ninth Academy is rich!"

Long Yaohua's introduction made all the big guys in the aerospace industry laugh.

Indeed, the Ninth Hospital is rich.

Although Dongfeng-31 is said to be the most top-secret project in the country, it is no secret for those involved in the project.Liu Yijiu's Ninth Academy is also top-secret, and even the Computer Research Institute and other units of their Ninth Academy are still undertaking some tasks.

"Little Liu, I heard that you put this missile on the ship? What kind of ship do you use to install it?" Du Jingkun was very skeptical. According to their current situation, Dongfeng-31 should be developed. After success, it was not too easy to install on the battleship in the hands of the Ninth Academy.

Not to mention the weight, just the diameter is too large, it is not an easy task.

Moreover, it is even necessary to ensure that the launch is carried out while moving at sea.

"Yes, we currently have 13 key technologies for this purpose. Although we have a large number of technologies acquired during the research of Dongfeng-22, they are all serious in solid fuel engines, propellant synthesis, bullet-cone composite material manufacturing, and large-scale special trailer manufacturing. Challenge. In a short period of time, it is difficult to develop successfully. Every technology requires continuous breakthroughs!" Qian Xuesen also felt that Liu Yijiu was a bit whimsical, "Actually, Dongfeng-31 is not suitable for boarding. The diameter is too large. ."

After Dongfeng-22, that is, the 202 project was dismantled due to Liu Yijiu’s suggestion in 1983, the joint demonstration team’s argumentation put forward the "large diameter, basic model, and serialization" plan, which was approved by the Military Commission and the Military Commission. In the same year, Dongfeng-31 was launched.

This is two years earlier than in history.

However, it was not because of early research that the key technologies of these missiles have achieved greater breakthroughs.

Especially for large solid fuel engines, composite solid propellants, composite materials, and even large special trailers, there is no domestic experience.

Dongfeng-6 and Dongfeng-7 have studied these technologies for a long time. At this time, the basic data and technologies of those studies have come into use.

"Large diameter is not a problem. The problem is that we need the Dongfeng-31 to have a higher hit accuracy, a longer range, and a faster speed. Of course, if the diameter can be made smaller and the manufacturing cost lower, this is a better rocket. Engine, hasn’t the large solid rocket engine that we jointly developed with you have been tested? This is not a problem. As for the others, we don’t need trailers. We can get propellant synthesis. The rest is Composite materials, we can also solve this..." Liu Yijiu said without exaggeration.

Suddenly, some bigwigs in the Ministry of Space were shocked.

If so, the Ministry of Aerospace Industry only needs to deal with heavy trailers to make this long-range intercontinental ballistic missile capable of maneuvering launch!

"Really? Can you get the process of advancing synthetic agents? The speed of the reentry phase of the bullet will exceed Mach 10 after entering the atmosphere. How to solve the heat protection problem at that time?" Qian Xuesen frowned and asked Liu Yijiu.

This kid hasn't had a good conversation with him for several years, and now he doesn't brag about drafts!

"The Red Star-10 missile used by Nipudosan uses a single solid propellant, but the hydroxy-terminated polybutadiene allows the missile to reach a speed of Mach 12 outside the atmosphere. Is it easier to conduct new research on the basis of propellant? As for composite materials, we can use organic compounds such as aramid fiber/epoxy resin shell to reduce the weight of the missile shell. As for the top fairing and heat protection issues It's easier to solve it. Not much else, we can provide at least two kinds..." Liu Yijiu didn't brag about it.

They have the most advanced material in the world-graphene!

"Then you are talking about how to solve the heat protection problem of the missile reentry? Do you want us to tell you the design ideas?" Du Zhongkun was a little dissatisfied with Liu Yijiu's bragging.

Aerospace bigwigs are all upset.

If Liu Yijiu can't solve these problems and just brag here, it is estimated that he will have to be beaten by the end of this meeting.

Obviously seeing that the faces of the big guys around are not good-looking, Liu Yijiu didn't care at all. This time graphene was not given to them, but he proposed the solution of Dongfeng-31 in history.It's just that I'm sorry for Professor Pan Ding who has developed this material.

He is very familiar with the design of Dongfeng-31.

Immediately shook his head, "You think this thing is kept secret, and there is no mystery. It's not because of the miniaturized warhead design that makes the top fairing sharper, causing the warhead part to re-enter the atmosphere. The aerodynamic heating effect is obvious. The carbon/quartz ablation materials used by Dongfeng-5 can't prevent the heat generated at higher speeds..." Liu Yijiu's words shocked many aerospace leaders!

This is a top secret thing.

How did this kid know?

Youdao is a layman watching the excitement, and an expert watching the doorway. Long Yaohua is a layman. He is often resisted by these technical experts. This kid, Liu Yijiu, is obviously avenging him.Although he didn't understand what Liu Yijiu said, he was obviously very tall and profound, and the gang of big men who had stopped the aerospace industry naturally blossomed in his heart.

"Then you are talking about what materials to use!" Even Qian Xuesen was a little anxious.

If these problems are solved, Dongfeng-31 will soon be able to enter the sample trial production work.

The process can be improved by many times.

"It's very simple. Using high-purity viscose-based carbon fiber can solve this problem. I think everyone should know that in order to reduce weight and increase strength, our fighter planes and helicopters use a large number of composite materials..." Originally, Long Yaohua thought Liu Yijiu To provide graphene to the Ministry of Aerospace.

But I didn't expect that this kid had other materials.

In this case, graphene was not taken out, which shows that this kid attaches great importance to graphene.

Is a material really that important?

"High-purity viscose-based carbon fiber?" The aerospace bigwigs who understand materials frowned and thought.

"How about, let us start? If we cooperate, let's continue to talk. If we don't cooperate, then forget it. Just assume I haven't said it." Liu Yijiu said with a mean smile.

He was so cheap, he stopped at this moment.

It's like a man takes off his pants and is about to pounce on a beautiful woman who is scratching her head, and then the beautiful woman tells him, give the money, if you don't give it, you won't continue...

At this time, besides giving money, what can a man do?

After all, the pants were all taken off, and it was confirmed that it was not a fairy jumping or something.

"Do you mean to cooperate with us?" Du Zhongkun understood. The Ninth Hospital has a lot of appetite.

"Of course, so much of the technology is provided by us, can we not intervene? Although we are not proficient in the overall technology of all bombs, high-precision guidance and so on, but the materials and other things are not a problem. We can't give it for nothing. Your technology, when you sell missiles to us in the future, can't you still ask for it?" Liu Yijiu said half jokingly and half seriously.

"As long as the material you said is proven to be valid, I will cooperate with you!" Qiang said, although this feeling is particularly awkward.

"Everyone knows that carbon fiber is more heat-resistant, but it is not easy to use carbon fiber to make a fairing, and it has very high strength. It just so happens that our Ninth Academy has done a lot of research on this aspect of materials. Therefore, we have the industrialized production technology of this material!" What Liu Yijiu did not say is that this is actually a poor material used to replace the high cost of graphene.

The production cost of graphene is too high, but the strength is sufficient. Therefore, the Ninth Institute has devoted much effort to the research of carbon fiber.

He said that the high-purity viscose-based carbon fiber has not been successfully developed, but he knows the formula, so it will not be too difficult.

"go on……"

"Continue? That's all, of course, after signing the contract, it's more than that..."
