Chapter 438

Zhuang Jianye's tone is slow, like an old man repeating the rules left by generations, simple and boring.

But in fact, Zhuang Jianye's words are not exaggerated at all, because the composite aramid paper honeycomb structure material combined with the autoclave curing process, and the manufacturing technology of the integral fuselage without ring-shaped load-bearing structure, let alone the west, is to look at the whole solar system, and Tengfei aviation manufacturing corporation is the only one.

This is not to say that western countries have not studied in this field, but most of them focus on the military field. Even so, the composition of their honeycomb composite materials is not as reasonable and advanced as that of Tengfei aviation manufacturing corporation.

Because they use aluminum honeycomb, through phosphoric acid anodizing technology, the aluminum surface is optimized, and the corrosion-resistant rubber bottom is added to make the durability of aluminum honeycomb reach the standard of aviation aluminum, and then two pieces of aluminum or other metal skins are matched to make honeycomb structural components.

The control surfaces of F-15 and F-18 in the United States use this kind of aluminum honeycomb components.

Due to the defects of aluminum itself, this kind of components can not solve the problem of electrochemical corrosion all the time, so there are problems in strength and durability. Therefore, it is difficult to make the main structural components of the aircraft, and can only be used in the control wing and other non load bearing components.

This is also the reason why there has been no large-scale promotion of this kind of cellular components.

Apart from the advanced research project of titanium aluminum alloy, other metal materials of Tengfei aviation manufacturing corporation are no better than those of ordinary aviation manufacturers. Therefore, Tengfei aviation manufacturing corporation has no idea what phosphoric acid anodizing technology is used to treat aluminum surface.

Of course, even if Tengfei aviation manufacturing corporation can figure it out, it will not go to the pole to do it. It has better aramid paper in its hand. Why should it still do something a generation behind?

Therefore, Tengfei aviation manufacturing corporation not only solved the inherent defects of aluminum honeycomb, but also made the structure more stable and mature, thus creating a lightweight and reasonable highland Eagle fuselage.

The reason why yun-6, the domestic version of plateau Eagle C, has a maximum range of more than 2200km with a load of 2.3 tons, is due to the subversive fuselage mechanism and manufacturing technology.

Although the Chinese version of highland hawk B and the low version of highland hawk a are both called highland hawks, they can't reach the level of Yun 6 in terms of range and load. Even if they are replaced with a more powerful engine, they can't be realized, because the difference between them is in the essence, and can't be made up by replacing that part.

However, even so, the materials and technology of yun-6 fuselage are still not the most advanced of Tengfei aviation manufacturing corporation. In order to reduce the production cost of yun-6, the back plate of aramid paper honeycomb structure is made of chemical milled aluminum nickel alloy sheet.

The aerospace technology R & D center of Tengfei Aviation Manufacturing Corporation started with T700 Carbon fiber composite panels.

In other words, before taking out the things pressed on the bottom of the box, Tengfei aviation manufacturing corporation just threw out a bronze trumpet and crushed many Western Kings.

Yes, it is rolling, because at this time, western countries have just made a breakthrough in aramid paper, and it will take some time for its real application.

In this respect, the French are better than the British and American. They have started preliminary application experiments, and even started in-depth experiments on mirage 2000 and other aircraft. However, their level is the same as that of yun-6 fuselage materials, and they may even be inferior to yun-6 in manufacturing level.

Because the French have never found a way to solidify the aramid paper honeycomb material with Al Ni alloy as backing plate, otherwise they would not have used this material only for the flaps, vertical tails and rudders of mirage 2000, gust fighter and A310 airliner in the 1990s.

It has been applied to their advanced civil service at any cost for a long time.

In addition to fighters and aircraft design software, Dassault's Falcon business aircraft is also an important source of revenue.

If they can make the integrated fuselage structure of shipment 6, it will be a big step up in economy, range and comfort. Unfortunately, Dassault has never made the big step from the beginning to the end.

The United States is not as fast as the French, but it has taken the same development path as Tengfei Aviation Manufacturing Corporation, that is, putting the treasure on carbon fiber composite materials, and made a breakthrough in the mid-1990s. As a result, a series of cross era aircraft models emerged one after another, sweeping the global aviation market from the end of the 1990s. It was not until the Boeing 737max incident that the United States stopped its hegemony The pace of the global aviation industry.

As for the other pole of the Soviet Union, the fighting people are extensive. They can throw steel plates into the sky and fly three mach, but they don't understand what is fine and comfortable. So they always have a backward understanding of composite materials. When they react, the whole country will be like broken glass and become a waste.

France, the fastest, won't apply it until the early 1990s; the United States, the slower, won't apply it until after the mid-1990s; the Soviet Union, with its great strength, has become a chicken feather without understanding it.

Who can audit plateau Eagle C? How to audit?The European Aviation Safety Commission and the Federal Aviation Safety Agency of the United States do not even have regulations on the characteristics of materials, how to prepare them, the process, the manufacturing process, the test data and the flight test. Do you ask them to review them?

The two organizations will immediately come up with a procrastination formula, and then squeeze out your technology on the condition of market access. After their own similar technology comes out, I'm sorry to tell you that I'll go back and change it again. Don't worry, this is definitely the last time.

It's better to hold the hegemony of technology and set up new standards instead of being punished by that bird. In any case, the application procedures and audit process items of airworthiness certificate in European and American countries are open. Just take a copy and make your own, and then add new standards of composite honeycomb materials.

Europe and the United States want to make a contribution in this respect. Sorry, the standard of systematization has been established. You can follow it.

What? I think China's standard is unreasonable. I want to make a new start. No problem. Would you like to know about the T700 Carbon fiber honeycomb composite of Tengfei aviation manufacturing corporation? The T800 and T1000 in the back are still in line. The models have begun to test fly, and their performance has been greatly improved. Do you follow your standards? Don't always be so low, OK!

In this way, it is difficult for Europe and the United States not to collapse. When the time comes, the standard of aircraft trial, at least the airworthiness standard of small and medium fixed wings, will be in the hands of China, which is very important to the domestic aviation industry.

Because this is tantamount to opening a gap in the international aviation market monopolized by Europe and the United States, so that China's aviation industry is no longer a sad onlooker, but a real participant. Finally, driven by the market, it will drive the rise of the entire aviation industry.

Because of this, Zhuang Jianye did not rush to Europe and America for airworthiness certificate like Binjiang factory. Instead, he racked his brains to seek the overall situation and dig a deep hole.
