Chapter 438 Technological Hegemony

Previous page        Return to Catalog        Next page

    Zhuang Jianye's tone was unhurried and unhurried, 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 to create an overall fuselage without an annular load-bearing structure is a production technology that can be used in the entire solar system, let alone the West.  , Tengfei Aviation Manufacturing Corporation, this is also the scorpion daddy, the only one.

    This is not to say that Western countries have no research in this area, but most of them are concentrated in the military field. Even so, the composition of their honeycomb structure composite materials is not as reasonable and advanced as that of Ascendas Aviation Manufacturing Corporation.

    Because they use aluminum honeycombs, the surface of the aluminum is optimized through phosphoric acid anodization technology, and a corrosion-resistant rubber base is added to make the durability of the aluminum honeycomb reach the standard of aviation aluminum, and then it is paired with two pieces of aluminum  Or other metal skins to make honeycomb structure components.

    The control surfaces on the American F-15 and F-18 use this type of aluminum honeycomb assembly.

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

    This is also the reason why such honeycomb components have not been promoted on a large scale since their advent.

    In terms of metal materials, except for the advanced research project of titanium-aluminum alloy, Tengfei Aviation Manufacturing Corporation is no better than ordinary aviation manufacturers. Therefore, Tengfei Aviation Manufacturing Corporation has never developed any phosphoric acid anodization technology to treat aluminum surfaces.  not understand.

    Of course, even if Tengfei Aviation Manufacturing Corporation can figure it out, it won't go to the trouble to do it. If it has better materials like aramid paper, why bother to make something that is 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 the thin and reasonable plateau eagle fuselage.

    The reason why the domestic version of the Plateau Eagle C, the Y6, can carry a load of 2.3 tons and have a maximum range of more than 2,200 kilometers is due to its disruptive fuselage structure and manufacturing technology.

    Although the mid-range Plateau Eagle B and the low-range Plateau Eagle A are both called Plateau Eagle, they cannot reach the level of Yun-6 in terms of range and load. Even if it is replaced with a more powerful engine, it cannot be achieved because  The difference between the three is in the bones and cannot be made up by replacing parts.

    However, even so, the materials and processes of the Y-6 fuselage are still not the most advanced by Tengfei Aviation Manufacturing Corporation. You must know that in order to reduce the production cost of the Y-6, the back panel of the aramid paper honeycomb structure is made of aluminum-nickel alloy that has been chemically milled.  sheet.

    The aviation technology research and development center under Tengfei Aviation Manufacturing Corporation initially used wall panels made of T700 carbon fiber composite material.

    In other words, Ascendas Aviation Manufacturing Corporation hasn¡¯t even taken out the stuff at the bottom of the box. It just threw out a bronze trumpet and crushed all the Western kings.

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

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

    Because the French have never found a way to integrally solidify the aramid paper honeycomb material with aluminum-nickel alloy as the backing plate, otherwise the French would not have used this material only for Mirage 2000, Rafale fighter jets and A310 passenger aircraft in the 1990s.  flaps, vertical fins and rudder surfaces.

    It has long been used on their advanced business aircraft at all costs.

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

    If they can make an integrated fuselage structure like the Y-6, it will be equivalent to a big step in economy, range and comfort. It is a pity that Dassault has never reached this big step.  .

    The United States is not as fast as the French, but it has followed the same development path as Tengfei Aviation Manufacturing Corporation, which is to focus on carbon fiber composite materials and achieve a breakthrough in the mid-1990s, resulting in a series of era-changing aircraft models.  They emerged one after another and began sweeping the global aviation market in the late 1990s. It was not until the Boeing 737MAX incident that the United States' dominance of the global aviation industry was slightly stopped.

    As for the Soviet Union at the other pole, the fighting nations are all crude. They can throw steel plates into the sky and fly at Mach 3, but they don¡¯t understand what it means.??Delicate and comfortable, so composite materials are always an afterthought. When the reaction comes, the whole country is like broken glass and has become a scum on the ground.

    France, which is the fastest, will not use it until the early 1990s; the United States, which is slower, will not use it until the mid-1990s; as for the Soviet Union, which is quite powerful, it has become a piece of cake before it can be understood.

    ????????????????????????????????????????????????????????????????????????? Off Plateau Eagle c Who can review?  How to review it?

    The European Aviation Safety Council and the Federal Aviation Safety Agency don¡¯t even have regulations on material characteristics, preparation methods, process conditions, manufacturing processes, test data and test flight conditions. You ask them to review it?

    The two institutions will immediately come up with a tactic, and then use market access as a condition to squeeze out your technology. When their own similar technology comes out, I am sorry to tell you that they can go back and change it. Don¡¯t worry.  This is definitely the last time.

    Rather than suffer that crime, it is better to hold on to technological hegemony and set standards all over again. Anyway, the application procedures and review process items for aviation airworthiness certificates in European and American countries are public. Just get a copy and formulate your own, and then  Little by little, new standards in composite honeycomb materials are added.

    Europe and the United States want to make achievements in this area. Sorry, the systematic standards have been established. Just follow them.

    What?  If you feel that China's standards are unreasonable and want to start anew, no problem. Would you like to learn more about Ascendas Aviation Manufacturing Corporation's carbon fiber honeycomb composite materials based on T700?  The T800 and T1000 models are still queuing up. The models have begun test flights, and their performance has improved a lot. Do you want your standards to follow suit? Don¡¯t always be so low!

    " In this way, it will be difficult for Europe and the United States not to collapse. When the time comes, the aircraft flight test standards, at least the airworthiness standards of small and medium-sized fixed wings, will be in China's hands. This is really important to the domestic aviation industry.

    Because this is equivalent to opening a gap in the international aviation market monopolized by Europe and the United States, China's aviation industry will no longer be a miserable onlooker, but a real participant. Ultimately, 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 airworthiness certificates like Binjiang Factory. Instead, he racked his brains to figure out the overall situation and dig a deep hole.
