Chapter 1246

  "A 7.2-meter titanium alloy large structure?"

  After hearing Zhuang Jianye’s words, the senior researcher was fine. The squinted eyes of the head of the headquarters on one side suddenly widened, but the next moment he squinted again, watching Zhuang Jianye questioningly and asked, “What is this part of the project?”

  Yes, what kind of aircraft component is this?

  It was not only the head of the headquarters who was puzzled, but almost everyone including the military leaders issued the strongest question to Zhuang Jianye with silent eyes.

  There is no way. If these people are ordinary people, it will be fine. Zhuang Jianye can just say what he wants. Old Zhuang pretends to be 13, and they just cooperate. Anyway, they don’t understand anything.

The problem is that whether it is a military leader or a senior researcher, these senior cadres living in the temple themselves are the initiators and approvers of various key projects. If there is any aviation project that requires a titanium alloy with a cross section of 7.2 meters Can they be unclear about large structures?

  Maybe you don’t have to wait until now. This group of people went to China to take off here to see the freshness. You must know that the manufacturing technology of such large-size titanium alloy large-scale structural parts is one of the core production technologies for the next generation of combat aircraft.

After all, both high maneuverability and supersonic cruise are a great test for the structural strength of the airframe, not to mention the superposition of the two, and the total structure should be controlled as much as possible. The combination of various factors is for manufacturing. It is tantamount to change ~~~ state.

If this is not the case, the next-generation fighter aircraft is so good, why so far only the United States can develop and produce, other countries, including Russia, at most, only a little touch, even further in-depth is cautious, not the overall design of the next-generation fighter aircraft How difficult, or how complicated is the startup shape.

  The main reason is that the manufacturing is too difficult. Even if there are drawings and theories, it may not be possible to make them.

  This is like a commercial house, the clean water house, fine decoration and luxurious decoration are the same. The house is the same house, but the quality of the decoration can make the comfort of the house very different.

  Because of this, if China Ascendas can really produce large-scale titanium alloy structural parts with a cross-section of 7.2 meters, it is estimated that military leaders and others will be as excited as winning tens of millions of lottery tickets.

  After all, this means that the country has overcome another next-generation combat aircraft manufacturing problem, thereby greatly accelerating the development and installation speed of domestically-made next-generation combat aircraft.

  The question is, is there such a project? If so, how come they don’t know if these temples are on the bus?

  Zhuang Jianye, of course, knew what the leaders thought and thought, so he quickly explained: “This large-scale structure is not a project in the aviation field.”

   "The aerospace field seems to be..."

As soon as Zhuang Jianye's words were spoken, the head of the headquarters had to refute, but when the word "no" was about to blurt out, the head of the headquarters suddenly realized something, his squinted eyes widened again, and he asked with a trembling tone: " Xiaozhuang, don't sell offenses this time. Is the supersonic wind tunnel project promising?"

As a result, before Zhuang Jianye could answer, the military leader stepped forward, took Zhuang Jianye’s hand, and urged with a trembling tone: "Xiao Zhuang, you really got the supersonic wind tunnel out? Go... hurry. Take me to see it, it's the most important weapon in the country!"

Zhuang Jianye did not expect that the two chiefs in the army would be the same as the children who saw the novel toys. They have been able to directly break the gong after years of raising qi. It is estimated that if you don't see it with your own eyes, you will lose two catties of meat with your own hands. .

   But think about it, what is a super-supersonic wind tunnel? As the military leaders said, it is an absolute national weapon. Because of this thing, it can simulate the attitude of the aircraft at a supersonic speed between 1.5 kilometers\second and 7 kilometers\second. And structural situation.

That is, between Mach 4 and Mach 20, the various performance parameters of the aircraft no longer need to be fired on the field. The so-called test is carried out, which is laborious, and the scale model can be used directly on the ground to fully grasp the various parameters. In hand.

It plays a vital role in cutting-edge scientific theories and applied research on hypersonic vehicles, high-combustion ramjets, critical space flight devices, reentry missile warheads, QXS ballistics, Sanger ballistics, near-Earth space physics, etc. .

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

In the words of Antonov, the director of the U-12 shock wave wind tunnel laboratory of the National Central Institute of Machinery of Russia, the largest supersonic wind tunnel in the world today: "It is also very simple to know our test results. That is to declare war with us now, and I promise you will know how well our test results for so many years are in the next second!"

It is full of simple and rude ridicule in the bear version. Although it is somewhat biased, it cannot be denied that the essence of Antonov’s words is quite reasonable. That is, all the experimental research on this kind of wind tunnel facility is a national strategic security. Cornerstone.

  Because of this, the country will spare no effort to invest heavily in this area to build its own super-supersonic wind tunnel.

There is no way. After the end of the Cold War, objective factors at home and abroad have urged the country to exert efforts in this regard. Not to mention anything else, the reentry warhead of the anti-ship ballistic missile in the "killer" program is in a sense. It is a kind of hypersonic aircraft.

  In order to further enhance the penetration capability, increasing the speed of re-entry is an inevitable choice. The problem is that in this regard, two low-Earth orbit space tests have been conducted in China, and they all ended in failure.

  It is because the material's thermal insulation performance is not enough~lightnovelpub.net~ cannot guarantee 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 capable of performing Mach 20 in China, and basic data indicators cannot be given. Naturally, there is no way to come up with an effective solution in this regard.

  The other is the anti-missile satellite weapon system in the killer plan. Whether it is mid-range interception of medium- and long-range ballistic missiles or attacking satellites in low-Earth orbit, it involves the high-speed flight control and precision guidance of the attacking warhead in the adjacent space.

  If this thing is fired with one round, the cost of the launch vehicle alone is an astronomical figure, not to mention other things.

The more important thing is that the anti-missile\satellite weapon system must not be produced in the country. Let alone the surrounding ballistic missiles, such as forests and seas, threatening national security. More importantly, if you don’t have this thing in your hand, you will have to launch your own satellites. Worrying, after all, the feeling that you can't fight back if someone hits you casually is really uncomfortable.

  Based on the above, the ultra-high supersonic wind tunnel is not to be done in China, but has to be done.

  It’s just that the military leaders and others did not expect that China, which is in charge of this project, has made significant technological progress so quickly. How can the military leaders and the heads of headquarters not be excited, how can they not be excited!
