Chapter 1246

"7.2m titanium alloy large structure?"

After listening to Zhuang Jianye's words, the senior researcher didn't know much about it. The head of the headquarters on one side suddenly opened his eyes, but at the next moment he squinted again. Looking at Zhuang Jianye, he asked: "what is the part of the project?"

Yes, what kind of aircraft parts are these?

It's not only the head of the headquarters, but also the leaders of the army. Almost all of them asked Zhuang Jianye the strongest questions with silent eyes.

I can't help it. These people are just ordinary people. Zhuang Jianye can say whatever he wants. Lao Zhuang Zhuang Zhuang is 13. They just cooperate. Anyway, they don't know anything.

The problem is that whether they are military leaders or senior researchers, these senior cadres who live in temples are the initiators and examiners of various key projects. If there is an aviation project that needs a large titanium alloy structure with a cross section of 7.2 meters, can they not know?

Maybe they don't have to wait until now. Long ago, these people went to take off in China to see something new. You should know that the manufacturing technology of large titanium alloy structural parts with such a large size is one of the core production technologies of the next generation of combat aircraft.

After all, both high mobility and supersonic cruise are a great test for the strength of the airframe structure. What's more, the combination of the two factors and the total amount of the structure should be controlled as far as possible. Combined with various factors, it is no different for manufacturing.

If not, the next generation fighter is so good, why so far only the United States can develop and produce it, and other countries, including Russia, at most just touch it a little, and even go further carefully, it's not how difficult the overall design of the next generation fighter is, or how complex the starting shape is.

The main reason is that it is too difficult to manufacture. Even if there are drawings and theories, they may not be able to make them.

This is just like commercial housing, clean water housing, fine decoration and luxury decoration. The house is the same house, but the quality of decoration can make the comfort of the house very different.

Because of this, if China's take-off can really produce large titanium alloy structural parts with a cross-section of 7.2 meters, it is estimated that the excitement of military leaders and others is no less than winning tens of millions of lottery tickets.

After all, this means that China will overcome another manufacturing problem of the next generation of combat aircraft, thus greatly speeding up the development progress and installation speed of the next generation of domestic combat aircraft.

The question is, is there such a project? If so, how can they not know the existence of these temples?

Of course, Zhuang Jianye knew what the leaders thought, so he quickly explained: "this large structural component is not a project in the aviation field."

"It seems that the space field is also..."

As soon as Zhuang Jianye's words came out, the head of the headquarters would retort. However, when the word "no" was about to blurt out in the end, the head of the headquarters suddenly realized something. His narrowed eyes widened again, and then he asked carefully in a trembling tone: "don't sell this time, Xiao Zhuang, Is there something in the super hypersonic wind tunnel project? "

As a result, before Zhuang Jianye waited for an answer, the leader of the army stepped forward, took Zhuang Jianye by the hand, and urged him with the same trembling voice: "Xiaozhuang, have you really made the hypersonic wind tunnel? Let's go... Take me to have a look. It's the most important tool of our country

Zhuang Jianye didn't expect that the two leaders in the army, like the children who saw the novel toys, had directly broken the skill of Nourishing Qi for many years. It's estimated that if they don't see it with their own eyes, they will lose two kilograms of meat.

But think about it. What's that? As the leader of the military said, it is absolutely the most important tool of our country, because with this tool, we can simulate the attitude and structure of the aircraft at a supersonic speed between 1.5 kms and 7 kms.

That is to say, between Mach 4 and Mach 20, the performance parameters of the aircraft no longer need to be tested by firing test bombs on the ground, and the so-called tests will cost people and money. The parameters can be completely mastered by using the equal scale model directly on the ground.

It plays an important role in the research of hypersonic vehicle, high fuel ramjet, critical space flight device, reentry missile warhead, QXS trajectory, Sanger trajectory, near earth space physics and so on.

Because of this, such wind tunnel facilities have always been regarded as prohibited by developed countries. Not only the export of related technologies is prohibited, but also the test data and relevant conclusions obtained by using such facilities are rarely published.

In the words of Antonov, director of the U-12 shock tunnel laboratory of the State Central Institute of mechanical research in Russia, the largest hypersonic wind tunnel in the world, it is very simple to know our test results, that is, declare war with us now, and I promise you will know how good our test results are in the next secondIt's full of bear's simple and crude ridicule. Although it's biased, it can't be denied that the essence of Antonov's words is very reasonable, that is, all the experimental research of this wind tunnel facility is the cornerstone of a national strategic security.

Because of this, China will spare no effort to invest a huge amount of money in this area to build its own hypersonic wind tunnel.

No way. After the end of the cold war, objective factors at home and abroad forced China to make efforts in this regard. In a sense, the reentry warhead of the anti-ship ballistic missile in the "killer's mace" plan is a hypersonic vehicle.

In order to further enhance the penetration capability, it is an inevitable choice to improve the reentry speed. The problem is that two low earth orbit space experiments have been carried out in China in this respect, both of which ended in failure.

The obvious reason is that the thermal insulation performance of the material is not enough to ensure that the guidance system in the warhead will not be burned when the speed reaches Mach 20.

In fact, the fundamental reason is that there is no wind tunnel test equipment at Mach 20 in China, and the basic data indicators can not be given, so there is no effective solution in this respect.

The other is the anti missile satellite weapon system in the killer's mace program. Whether intercepting medium and long range ballistic missiles in the middle or attacking satellites in low earth orbit, it involves the high-speed flight control and precise guidance of the attacking warhead in near space.

If this thing relies on one actual bomb, not to mention the other, the cost of the launch vehicle alone is astronomical.

What's more important is that the anti missile satellite weapon system can't be produced at home. Let's not say that the surrounding ballistic missiles are like forests and seas, threatening national security. More importantly, if you don't have this thing in hand, the satellites you launch will have to be worried. After all, it's really hard to feel that if someone hits you casually, you can't fight back.

Based on all of the above, it is not necessary but necessary to do it in China.

What the military leaders and others did not expect is that China's take-off, which is responsible for this project, has made significant technological progress so soon. How can the military leaders and the head of the headquarters not be excited
