Take Off My Aviation Era

, The fastest update to take off the latest chapter of my aviation era!

Zhuang Jianye's tone is not rushing, like an old master repeating the rules left by his ancestors for generations, unpretentious and very 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 molding process, the production technology of the overall fuselage without the ring-shaped load-bearing structure, let alone the West, is to look at the entire solar system. , Ascendas Aviation Manufacturing Corporation, this is also Xieziba, the only one.

This is not to say that Western countries have not researched in this area, but they are mostly concentrated in the military field. Even so, the composition of their honeycomb structure composite materials is not as reasonable and advanced as the Ascendas Aviation Manufacturing Corporation.

Because they use aluminum honeycomb, the surface of the aluminum is optimized through phosphoric acid anodization technology, and the corrosion-resistant rubber bottom is added to make the aluminum honeycomb durable up to the aviation aluminum standard, and then equipped with two aluminum materials Or other metal skins, made into honeycomb structure components.

This type of aluminum honeycomb components are used for the control rudder surfaces on the American F-15 and F-18.

Due to the defects of metal aluminum itself, this kind of components cannot always solve the problem of galvanic corrosion, so there are problems in strength and durability. Therefore, it is difficult to make the main structural components on the aircraft. They can only be used in non-load-bearing components such as control wing surfaces. Application on parts.

This is also the reason why such cellular components have not been widely promoted since they came out.

In addition to the advanced research project of titanium and aluminum alloy, Tengfei Aviation Manufacturing Corporation is no better than ordinary aviation manufacturing plants in terms of metal materials. Therefore, the phosphoric acid anodization technology is used to treat the surface of aluminum materials. do not understand.

Of course, even if the Ascendas Aviation Manufacturing Corporation can figure it out, it won't do it on the pole. With a better material like aramid paper in hand, why bother to do something that is a generation behind?

Therefore, Ascendas Aviation Manufacturing Corporation not only solved the inherent defects of aluminum honeycombs, but also became more stable and mature in terms of structure. Only in this way did it create a thin and reasonable plateau eagle airframe.

The domestic version of the Plateau Eagle C, Yun-6, has a maximum range of more than 2,200 kilometers with a load of 2.3 tons. The disruptive airframe structure and manufacturing technology are indispensable.

Although both the mid-range Plateau Eagle B and the low-profile Plateau Eagle A are called Plateau Eagles, they cannot reach the level of Yun-6 in terms of range and load. Even if they are replaced with more powerful engines, they cannot be achieved. The difference between the three is in the bones, and it can't be made up by changing that part.

However, even so, the material and technology of the Y6 airframe is still not the most advanced of Ascendas Aviation Manufacturing Corporation. It is important to know that in order to reduce the production cost of the Y6, the backplane of the aramid paper honeycomb structure is made of chemically milled aluminum nickel alloy. sheet.

The aerospace technology research and development center of Ascendas Aviation Manufacturing Corporation initially used wall panels made of T700 carbon fiber composite materials.

In other words, the Tengfei Aviation Manufacturing Corporation has not taken out the bottom of the box, but just throws a bronze trumpet and crushes a lot of Western kings.

Yes, it is rolling, because at this time Western countries have just made breakthroughs in aramid paper, and it will take some time before the real application.

In this regard, the French are better than the British and Americans. They have already begun preliminary applied experimental research, and have even begun to conduct in-depth tests on aircraft such as the Mirage 2000, but their level is the same as that of the Yun-6 fuselage materials. It may even be worse than Yun-6 in manufacturing.

Because the French never found a way to solidify the aramid paper honeycomb material with aluminum-nickel alloy as a backing plate, otherwise the French would not use this material only in the Mirage 2000, Rafale fighters and A310 airliners in the 1990s. The flaps, vertical tail and rudder surface of the aircraft.

It has long been used on their advanced corporate airframes at any cost.

We must know that in addition to fighter jets and aircraft design software under the French Dassault Company, their Falcon series business jets are also an important source of income for Dassault.

If they can make an integrated fuselage structure like the Yun-6, it will be equivalent to a big step in economy, range and comfort. Unfortunately, Dassault’s has never stepped past this big step. .

The United States is not as fast as the French, but it has followed the same development path as the Ascendas Aviation Manufacturing Corporation, which is to press Bao on carbon fiber composite materials and make breakthroughs in the mid-1990s, so a series of cross-era models One after another, they have swept the global aviation market from the end of the 1990s. It was not until the Boeing 737MAX incident that the United States was able to dominate the global aviation industry.

As for the Soviet Union at the other extreme, the fighting nations are extensive. They can throw steel plates into the sky and fly out of Mach 3, but they don’t understand what is fine and comfortable. Therefore, they always have an afterthought to composite materials. The country, like broken glass, has become the scum of a place.

The fastest France will not be used until the early 1990s; the slower United States will not be used until the mid-1990s; as for the powerful Soviet Union, it has become a feather without understanding it.

May I ask who can audit Plateau Eagle C? How to review?

The European Aviation Safety Commission and the Federal Aviation Safety Agency of the United States do not even have a charter on the characteristics of materials, how to prepare them, process conditions, manufacturing processes, test data, and flight test conditions. You ask them for review?

The two institutions will immediately come up with a drag strategy, and then squeeze your technology dry on the condition of market access. After their own similar technology comes out, I am sorry to tell you that I will go back and change it again, rest assured This is definitely the last time.

Rather than suffer the bird crime, it is better to hold the technological hegemony and set standards by yourself. Anyway, the application procedures and review process items for the aviation airworthiness certificate of European and American countries are all public. UU read www.uukanshu.com and took a copy. Just make your own, and then add new standards in composite honeycomb materials little by little.

Europe and the United States want to do something in this regard. I'm sorry, the system standards have been established, so follow them.

what? I feel that China’s standards are unreasonable, and I want to start anew, no problem. Ascendas Aviation Manufacturing Corporation’s T700-based carbon fiber honeycomb composite material, should I know about it? The T800 and T1000 models are still in line behind, and the models have begun to fly, and the performance has improved a lot. Do you follow your standards? Don't always be so low, OK!

In this way, it will be difficult for Europe and the United States not to collapse. When the time comes, aircraft test standards, at least the airworthiness standards of small and medium-sized fixed wings, will be held in China's hands. This is too important for 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 bystander, but a real participant. Eventually, 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 the United States to get some airworthiness certificates like the Binjiang Factory, but racked his brains to find a general situation and dig a deep hole.
