Chapter 987

Yes, at that moment, from the head of the headquarters to the ordinary technicians, the brain was blank.

The original good "recoverable satellite" disintegrated in the low earth orbit space 33 kilometers away from the ground, scattered into hundreds of debris, which disappeared in the air like a woman in the sky. Only a few fragments were preserved and fell into the Xilinguole desert in Inner Mongolia.

In addition, foreign institutions and media that have been closely following the domestic space science experiment reported how the domestic space technology lagged behind and how the technology failed in the first time when the experiment failed.

Some western media even commented that domestic technology alone is not enough to gain a foothold in outer space.

In other words, the western media implied that the domestic aerospace industry relies on foreign technology to achieve brilliant performance in recent years. However, when it comes to foreign technology fields that restrict transfer, such as the so-called "recoverable satellite", the real face of China will be exposed, and it's hard to win.

As soon as this kind of view came out, other media echoed it one after another. For a moment, there was a lot of foreign voices about the domestic aerospace industry, so many government organizations or commercial groups who wanted to hand over commercial satellites to domestic launch had to flinch, for fear that the domestic technology would really pull the hip and blow up their satellites.

However, this is not a real pain for Tengfei group and even the Aerospace Department. What worries the whole country is that some politicians in Europe and America who are supported by the aerospace giants such as Loma and Boeing began to jump up and down with this report.

What is the saying that China has squeezed its commercial aerospace market share with its advanced technologies from Europe and the United States.

What's more, huge domestic subsidies in commercial space violate trade rules.

One of them, a senator from a big foreign country named koske, clamored in public that Europe and the United States should ban the export of advanced space technology and equipment to China, so as to keep the high profit commercial space launch business in a big foreign country and promote the employment of his own country.

Although koske's agitation did not make the European and American governments make any substantive action, the technology transfer and parts export in some key areas have obviously tightened domestic pressure.

For Tengfei group and even the whole aerospace industry, it is no different from taking a deep cut. Although the domestic aerospace development is very fast in recent years, the short board is also becoming more and more prominent, such as advanced materials, high sensitivity sensors, advanced processing equipment, etc., which can not be produced independently at home and still need to be imported from abroad.

As a result, at this time, Europe and the United States restrict the export of aerospace technology, which is obviously detrimental to the development of domestic aerospace industry.

It's a good thing to say that commercial aerospace will lose a little money, but the "Assassin's mace" plan is a national weapon comparable to two bombs and one satellite, which is the strategic cornerstone of whether China can really rise in the future.

Especially in a big country outside the region, the combat effectiveness of the aircraft carrier battle group is becoming more and more powerful. The steady progress of the national missile defense system and the regional missile defense system, two ballistic missile interception systems born out of the Star Wars plan, highlights the necessity of the "killer mace" plan.

Because of this, the impact of export restrictions in Europe and the United States on the "Assassin's mace" program is enormous.

If not, the head of the headquarters could not have been so angry. The failure of this space science experiment is like a domino, causing a series of unpredictable consequences, and eventually a super earthquake in the aerospace industry.

No matter how judged at home, in the eyes of foreign countries, this failure is just like the little boy who dares to speak in the emperor's new clothes, exposing the weakness and weakness of the domestic aerospace industry.

Not to mention the plans that affected the headquarters, they lost face abroad, and the direct and indirect losses were as high as tens of billions.

Don't mention the head of the headquarters. Even if you change any leader, you have to beat the table and curse your mother.

What's more, Zhuang Jianye and Tengfei group were not wronged.

Because the main reason of failure is on the shell of fiber reinforced ceramic matrix composite warhead.

The ground test data show that the maximum temperature at the top of the missile body will reach about 2750 ℃ when the warhead makes the first jump in the near earth space orbit 45 km from the ground.

At this temperature, a 2.36 micron oxide layer will be formed on the surface of the shell.

According to the calculation of Tengfei group, the oxide layer which is less than the diameter of hair can be ignored.

As a result, it's the oxide layer that's what's going on.

According to the research on the recovered fragments, the technicians found that the 2.36 micron oxide layer in the ground test was really insignificant, but in the actual operation of low earth orbit, such a thin oxide layer was still the fatal wound of the final disintegration of the projectile.

Because in the hypersonic state, there are not only high temperature, high pressure, but also creep produced by oxidation reaction.

When the warhead is flying at a high speed in the near earth space orbit 45 km away from the ground, the 2.36 micron oxide layer will cause a twist like curl on the surface of the projectile under the action of high-speed impact air, and eventually it will be completely disintegrated.

Therefore, the failure investigation expert group concluded that in order to resist the creep impact, the high temperature oxidation layer of the warhead shell must be less than 1 micron.In other words, the main cause of the accident is that Tengfei group made serious mistakes in the calculation and verification of materials, resulting in the failure of the test.

Zhuang Jianye said that he would not hold back his grievances.

From the 23rd branch to today's Tengfei group, for more than ten years, only Zhuang Jianye pointed at other people's noses and scolded them. When was it that so many people were scolded?

However, Zhuang Jianye didn't blame the head of the headquarters for his ruthlessness. On the contrary, he was very grateful to the backstage boss who had been giving his platform.

Because this fierce training is tantamount to a curse and no enmity. Otherwise, the share of commercial space launch will be sharply reduced, the import of advanced space technology will be limited, and the impact of other industries will be too large. Therefore, the head of the headquarters scolds himself as protecting himself. Otherwise, those passive interest groups will not be able to spare him, Zhuang Jianye, the troublemaker.

This is also why Zhuang Jianye treats whisker ceramic cutting tools in a low-key way. This kind of ceramic material can be used to float warhead shells. Although it can not be regarded as a miracle because of the 1.36 micron oxide layer error, it is a very excellent special cutting tool material.

After all, the strength, heat resistance and oxidation resistance of the same kind of materials are outstanding, so the killer can't be used, and it can't be swept into the garbage heap to waste. How to say, it's also from Tengfei group, so we must make the best use of the materials according to the internal urine property of Tengfei group, and squeeze the last first surplus value dry.

However, it's not good to take it out and make money openly. After all, the elder brothers of aerospace system are worried because they are restricted by Europe and the United States. What do you think of your big profits with special knives? Do you think we are not miserable enough and we need to sprinkle salt on the wound?

The elder brother of aerospace is not the younger brother of aviation. They are all real elder brothers. They are very reasonable. They are really irritating. They are not as good as Zhuang Jianye.

Therefore, it is necessary to keep a low profile!
