Take Off My Aviation Era

"Take off my aviation age novel ( to find the latest chapter!

Yes, at that moment, the heads of the headquarters and the ordinary technicians were counted one by one, and the brain was completely blank.

The original “returnable satellite” disintegrated in the low-Earth orbit space 33 kilometers from the ground, scattered into hundreds of fragments, and disappeared in the air like a celestial flower. Only a few fragments were retained and dropped. In the desert of Xilin Gol, Inner Mongolia.

Not only that, foreign institutions and media that have been paying close attention to this domestic space science experiment have overwhelmingly reported how the domestic space technology was behind and how the technology failed the first time the experiment failed.

Some Western media even made comments that domestic technology alone is not enough to gain a foothold in outer space.

In other words, this Western media alluded to the fact that domestic aerospace relies on foreign technology to achieve outstanding performance in recent years, but when it comes to foreign technology areas that restrict transfers, such as the so-called "returnable satellites", the real domestic face It was exposed, it was hard not to pull the hips.

As soon as this kind of view came out, other media echoed it. For a moment, the foreign slang of domestic aerospace was so loud that many government organizations or commercial groups that wanted to hand over commercial satellites to domestic launches had to stay away, for fear of domestic technology. The hips were blown up by their satellites.

However, this is not a real pain for the Ascendas Group and even the aerospace sector. What really worries the country is that certain politicians in Europe and the United States who are supported by the aerospace giants such as Lockheed Martin and Boeing began to jump up and down with this report.

Said that the domestic use of their European and American advanced technology to squeeze the domestic commercial aerospace market share.

He also said that the huge domestic subsidies in commercial aerospace violated trade rules.

One of the senators from a large foreign country named Kosk even clamored in public, demanding that Europe and the United States prohibit the export of advanced aerospace technology and equipment to the country, so as to keep the high-profit commercial space launch business in a large country outside the region and promote employment in the country. .

Although Kosk’s agitation did not make the European and American governments take any substantive actions, the transfer of technology and the export of parts and accessories in certain key areas have been significantly tightened for the country.

For Ascendas Group and the entire aerospace industry, this is no different from the bottom line. It should be understood that although the domestic aerospace development has been rapid in recent years, the shortcomings have also become more prominent, such as advanced materials, high-sensitivity sensors, advanced processing equipment, etc. , Domestic production is not yet possible, and large quantities of imports are still needed from abroad.

As a result, restrictions on technology exports in the aerospace sector in Europe and the United States at this time are obviously detrimental to the development of the domestic aerospace industry.

For commercial aerospace, it’s a big deal to lose a little money, but the "killer" program is a weapon of the country comparable to two bombs and one star, and it is the strategic cornerstone of whether China can truly rise in the future.

In particular, the combat effectiveness of a major aircraft carrier group outside the region has become more and more powerful. The steady advancement of the two ballistic missile interception systems, the National Missile Defense System and the Regional Missile Defense System, born out of the Star Wars program, has become more and more necessary for the "killer" program. Stand out.

Because of this, restrictions on exports from Europe and the United States have had a huge impact on the "killer" program.

If not, it is impossible for the head of the headquarters to make such a big fire. It is true that the failure of this space science experiment is like a domino, triggering a series of unpredictable consequences, and finally triggering a super seismic magnitude impact in the aerospace industry.

That is, no matter how domestically judged, in the eyes of foreign countries, this failure is like the little boy who dared to speak in the emperor's new clothes, exposing the shortcomings and weakness of domestic aerospace like the Emperor Chiguoguo.

Not to mention the plan that affects the headquarters, the shame has also been lost abroad, and the direct and indirect losses are as high as tens of billions.

Not to mention the head of the headquarters, even if you change any leader, you will have to slap the table and scold your mother.

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

Because the main reason for the failure was the fiber-reinforced ceramic matrix composite bullet shell.

Ground test data shows that the highest temperature at the top of the projectile will reach about 2750 degrees Celsius when the warhead is in the near-Earth space orbit 45 kilometers above the ground.

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

According to the calculations of Ascendas Group, this oxide layer which is less than the diameter of the hair can be completely ignored.

As a result, the thing happened on this oxide layer.

According to the research on the recovered fragments of the projectile, the technicians found that the 2.36 micron oxide layer in the ground test is indeed insignificant, but in the actual operation of the low-Earth orbit, such a thin layer of oxide layer will become the final disintegration of the projectile. Of fatal injuries.

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

This caused the warhead to fly at high speed in a near-Earth space orbit 45 kilometers from the ground. Under the action of the high-speed impact air, the 2.36-micron oxide layer caused a twist-like creep and distortion on the surface of the projectile, and finally disintegrated completely.

Therefore, the fault investigation expert group concluded that in order to resist this creep impact, the high temperature oxide layer of the warhead shell must be less than 1 micron.

In other words, the main cause of the accident was that Ascendas Group made serious mistakes in the calculation and verification of materials, which led to the failure of the test.

Zhuang Jianye said it was false if he didn't hold back.

From the twenty-third branch to the current Ascendas Group, for more than a decade, only Zhuang Jianye pointed at someone else’s nose and scolded him. When was he being trained by so many people?

However, Zhuang Jianye did not blame the head of the headquarters for being more popular and unrelenting. On the contrary, he was very grateful to the backstage boss who had been giving him a platform.

Because this severe training is tantamount to swearing, otherwise the share of commercial aerospace launches will be sharply reduced, the import of advanced aerospace technology will be restricted, and the impact of other industries will be too large. Therefore, the head of the headquarters is tantamount to scolding himself. It is to protect yourself, otherwise the interest groups that have passed Cheese will not spare him Zhuang Jianye, the troublemaker.

And this is why, Zhuang Jianye's low-key handling of whisker ceramic knives ~ www.readwn.com~ This kind of ceramic material used in the shell of the warhead can be used in water and bleaching, although because of the 1.36 micron oxide layer error, it can not be regarded as a shot into the soul. The miracle, but it is a very good special tool material.

After all, strength, heat resistance and oxidation resistance are all leaders in similar materials, so the killer is not available, nor can it be swept into the trash pile to waste. It is also from the Tengfei Group, which must follow the internal of the Tengfei Group. Urine requires the best use of the material and squeezes out the last remaining value.

However, it’s not good to use it for your own use. It’s a bit bad to make a blatant profit. After all, the big brothers in the aerospace system are grieving because of restrictions in Europe and the United States. You are making a big profit with special knives. What do you think of the big brothers? ? Do you think that we are not miserable enough and have to sprinkle salt on the wound?

The big brother of aerospace is not the little brother of aviation. They are all real big brothers. They are really irritating, and they are not as good as his Zhuang Jianye.

So, this person has to be low-key!
