You know, China Ascendas has not made a breakthrough in three-dimensional weaving technology with a flash of insight, but has been continuously investing for twelve years.

In other words, when China Ascendas was still a small Ascendas group, the three-dimensional weaving process had become the key core technology that Ascendas was preparing to overcome at that time.

There is no other reason for this, because when Ascendas Group was researching carbon fiber composite materials, it discovered a unique weaving method to change the arrangement order of carbon fiber filaments, so that the carbon fiber composite material made of carbon fiber composite material has a mirror reflection effect. , In order to reduce the radar reflectivity, to achieve the so-called radar stealth effect.

This discovery can be said to be one of the most important achievements of the Ascendas Department in the field of scientific research at that time. Once discovered, it was classified as confidential by the headquarters and focused on research and development.

No way, this discovery is really too important, because once this technological achievement is applied, it will not only solve the problem of stealth materials for next-generation combat aircraft and bombers, but more importantly, it can greatly reduce the post-maintenance and maintenance of stealth aircraft. The problem of high maintenance cost has greatly improved the equipment conditions, attendance rate and proper rate of stealth aircraft.

Let alone the country with insufficient financial resources at that time, even the United States, which accounts for more than 40% of the world’s total expenditure every year, would have rushed to shout, I want, I want, if it knew that the Ascendas Department had such technological achievements at that time. I want...

As the saying goes, the landlord’s family has no surplus. Although the United States has a lot of money, the ridiculously high post-maintenance and maintenance cost of the stealth aircraft still makes the US military a little overwhelmed.

The reason for this is very simple. Most of the stealth aircraft developed by the U.S. military were pre-researched in the 1970s and entered substantive research projects in the 1980s. Although the technology is still arrogant in the world and can be called the South Bay of the solar system, the concept is still seven. Old stuff from the eighties.

Therefore, the stealth of the US military is more dependent on advanced starting shape + non-metallic materials with low radar reflectivity + thick absorbing coating to reduce the effectiveness of radar detection.

China Ascendas directly overcame these three ironclad rules in the field of stealth aircraft design. Starting from the material itself, the material itself has strong radar wave absorption and scattering functions.

This is like playing a shy two-player game with the goddess. The prostrative little white face naturally has to perform foreplay due to physical reasons. What is 9, what is licking, tossing and tossing for more than an hour, the result is less than two minutes.

The tough guys are different. They are big, durable, and live well. Naturally, they don’t need any foreplay. They just push it to the first 60 minutes. If you feel uncomfortable, add another half an hour and let the goddess from the depths of the soul. Soaring to bliss.

Compared with the American flower work, the path for China to take off is more like a direct hard man. Since its own conditions are so good, it is regarded as a treasure by the Americans, and it has been classified as a confidential stealth paint for China to take off. The technological path can only be regarded as the icing on the cake, not a necessity to send charcoal in the snow.

It is good to be natural, which can further reduce the probability of radar reflection. If there is no problem, it is not a big problem, because the material itself has strong radar wave absorption and scattering functions, and can also achieve stealth effect.

Since complex and expensive stealth coatings have become dispensable, naturally there is no need to care so much about maintenance. Conditions can be sprayed. If there is no such condition, a layer of ordinary coating can still be used for the third-generation machine. Pressing on the ground and rubbing hard.

The problem is that China’s take-off’s technological path is good, but it is very difficult to achieve it. The reason is very simple, that is, the entire fiber weaving method is very complicated, so that in the first five years, the then Tengfei Group could only rely on simple The equipment manually completes the preparation of test samples.

The scrap rate and the waste rate of materials are terribly high, not to mention the time cost, which often takes more than three months to complete, but even so, only one test sample the size of a TV remote control can be produced at a time.

In this case, even if the carbon fiber special woven stealth path has a good prospect, it will never be practically applied. After all, stealth aircraft are industrial products, not works of art. Since they are industrial products, they involve large-scale mass production. China's take-off technological path can greatly improve the performance of stealth aircraft, which is useless when industrialized mass production is not possible.

Therefore, finding an industrialized mass production method that can mass-produce this special carbon fiber composite material with its own stealth properties became the focus of Tengfei Group's research in this field at that time.

However, the problem is that even if you know what the problem is, it is difficult to solve the problem, how to do it, how to do it, what solution to use, let alone the Ascendas Group at that time, it is estimated that the whole world is a brain Sub paste.

At the time when Ascendas Group was unable to solve the problem of the industrialized mass production of stealth materials, an article in the internal academic journal of the National Aeronautics and Space Administration obtained through a special channel attracted the attention of relevant team members of the Ascendas Group at that time.

The title of the article is "The Feasibility of Realizing Mirror Reflection of Carbon Fiber Materials by Three-Dimensional Weaving Technology". The author is Richard Mendelssohn, a Swedish-American aeronautical materials scientist who works in the Aeronautical Materials Laboratory of the National Aeronautics and Space Administration. Participated in the research and development of aerospace materials in many cutting-edge fields of the National Aeronautics and Space Administration.

And Mendelssohn’s article is a whim in his spare time, a hypothetical technical solution that uses NASA’s set of high-performance military reconnaissance satellites, advanced space telescopes, stealth aircraft, and new strategies. Transport aircraft and other aerospace products provide three-dimensional braiding machines composed of high-strength composite materials. Through reprogramming, new arrays can be constructed~lightnovelpub.net~ may be able to achieve a certain radar mirror reflection effect by changing filament winding and internal linking methods .

Although Mendelssohn's article did not specify the specific feasibility, and in the comments of the article, it was stated that this was just a guess, let alone a follow-up.

After all, DuPont stands behind the stealth paint of the US military. The annual benefits are not so big. If you really come up with a new thing that is not necessary for stealth paint, would you let DuPont drink the Northwest Wind Soldier?

Want to follow-up, unless DuPont is still about the same.

But regardless of whether there is a follow-up or no naming feasibility, for the Ascendas Group at that time, it is no different from obtaining the treasure, because the Ascendas Group, which has accumulated a lot in this regard, is very clear that Mendelssohn’s guess is not only correct. And the feasibility is extremely high.

What else is this talking about? The American experts have already named the direction, and then they are done with their arms up. So for more than ten years, through the first generation of DL-520 three-dimensional knitting machine; the second generation of DL-527 three-dimensional knitting machine, finally Last year, China Ascendas successfully developed the third-generation DL-535 three-dimensional braiding machine capable of weaving carbon fiber composite materials with its own stealth properties. Since then, it has become a world leader in this field!
