    "Old Huang, do you know how to speak? If you can't speak, just hold it in. No one will treat you as a mute!"

    As soon as Huang Feng finished speaking, Fang Yong, the head of the Northwest Aviation Factory, was not happy. Before Zhuang Jianye could speak, he rushed Huang Feng back and said with a serious face: "Why is Lao Zhuang a loser? It's obvious that he is a loser.  It¡¯s because Nm has gone to grandma¡¯s house, okay?¡±

    ¡°Pfft~~¡±

    Huang Feng, who was holding the tea, took a sip and immediately squirted, then laughed loudly: "Yes, yes, Lao Fang summed it up well, summed it up well!"

    Zhuang Jianye finally figured it out. The two people in front of him were not good birds. They were more vicious than the other. If it were anyone else, there really wouldn't be anything they could do against them.

    One is the boss of a successful group, holding the high-quality production project of Project 10; the other is the head of the Northwest Aviation Factory, the cradle of domestic transport aircraft and bombers.

    It can be said that he is a figure who can make the domestic aviation industry tremble even if he stomps his feet.

    But the problem is that Zhuang Jianye is not an ordinary person, so he coughed lightly: "3§­y-24 vacuum electron beam welding machine, y§£h-4500 large heat treatment furnace, §­§£-60 large X-ray irradiation machine, and the 55,000-ton die forging machine of the Ural Heavy Machinery Plant  Hydraulic press; 45,000-ton hot die forging press and 18,000-ton multi-directional die forging hydraulic press. I think there is no need to divide them equally. Anyway, our Ascendas Group is short of these things, so we just want to stay and put fcnb-2000 into good use.  , to save the industry from always calling me, Zhuang Jianye, bragging."

    "Don't don't don't!" After hearing Zhuang Jianye's words, Fang Yong stepped on the cat's tail and quickly stopped him: "These things are all big guys. You Ascendas Group has a place to put them."  ? Let us help you share some of it."

    "Yes, yes, yes" Huang Feng immediately agreed: "Lao Zhuang, I'm not talking about you, please don't always bring out fcnb-2000, okay? Others don't know, but Lao Fang and I don't know yet? That's it  A deceptive shill, a fishing bait, but in the end, you, the boss, took me seriously."

    "That's it, that's it you just fooled Lao Maozi and Lao Mei, but you actually came to fool us, Lao Zhuang Tonight Erguotou, Fenjiu, Xifeng, Wuliangye, and Maotai will come with two liang, otherwise we won't be able to pass this hurdle.  !" Fang Yong quickly made a stab.

    Seeing two of the top bosses in the domestic aviation industry acting like street gangsters, Zhuang Jianye was quite helpless. He didn't mind being shameless, but he met two even more shameless ones. That was all. The problem was this  These two shameless people were absolutely right.

    In fact, let alone the fcnb-2000 project, even the wd-60ml-22 turbofan engine hanging on the engine test bench is a cover-up.

    Because Ascendas Group has mastered only part of the preparation technology of high-strength and high-toughness composite materials at best, and in this technology tree, fundamentally different ratios of epoxy resins and other chemical agents will form materials with different properties. Because of this  , which can be flexibly configured in different fields according to the properties of different composite materials.

    This can not only optimize the performance of aerospace vehicles, but also control costs.

    Take the American F-22 fighter jet as an example. According to public information, nearly 25% of composite materials are used in the fuselage, and most of them are special composite materials with high strength and high toughness.

    In fact, this kind of high strength and high toughness has very obvious differences in state characteristics due to different positions on the F-22 fuselage.

    For example, the skin and side strips of the F-22's front fuselage use im75250-4 prepreg; the electronic equipment hatch uses im7apc-2 prepreg; the internal frame and fuel tank frame use im75250-4 prepreg.  im7pr500ptm prepreg; as for the air inlet, im7977-3 prepreg is used.

    The front fuselage alone uses four different composite materials. Although these composite materials are all reinforced with mi7 carbon fiber, the ratio of the epoxy resin at the back is different, which makes the final effect of the composite materials different.

    Some places simply require high strength and high toughness, some places require both of them and radar wave penetration, some places require extremely high heat resistance, and some places require corrosion resistance.  Sex needs higher indicators

    These things all require different epoxy resin ratios to achieve. The problem is that Ascendas Group currently only makes h-zb800 composite materials, which are only equivalent to the im75250-4 prepreg on the f-22.

    In other words, Ascendas Group currently only has the manufacturing technology for part of the skin and side strip materials of new generation combat aircraft. As for the composite materials of internal frames, fuel tank frames, air intakes, tail fins, electronic equipment doors and other parts,  Ascendas Group, let alone possessing it, is still confused about how to make a breakthrough and has no direction.

    If this were not the case, the new generation of combat aircraft at this time would not be pre-research, but could be officially developedThe project is established. After all, the key composite materials have been developed, and combined with titanium alloy and aluminum-lithium alloy, mass production cannot be said, but one or two prototypes can still be produced soon.

    The reason why the preliminary research project has not been formally established is that there is still a long way to go in many aspects.

    The same is true for the materials of the new generation of combat aircraft, and the same is true for the composite fan blades of turbofan engines. Ascendas Group can do it, but the things it makes can at most resist the impact of a 1 kilogram bird at a relative speed of 200 kilometers. No matter how big it is, it cannot withstand it.  Living.

    The composite blades equipped on the American General Motors ge-90 can withstand up to 6 kilograms of bird impact.

    No way, the American composite materials use im78551-7 prepreg that General Motors invested heavily in research and development. It is a high-strength and ultra-high toughness composite material. It is not as strong as the h-zb800 composite material of Ascendas Group.  A little bit.

    Because of this, the wd-60ml-22 turbofan engine is placed on the engine test bench and can be used as a showpiece to fool people. If it is actually installed on an airplane, if nothing happens, it will be a major accident. After all, it is larger than 1 kilogram.  There are so many birds, and those with a relative speed of more than 200 kilometers are even more childish. If we really want to collide, the scene

    Even the genuine products on the engine test bench are deceptive props, let alone the fcnb-2000 project drawn on the drawing board. To use an unceremonious word to describe it, it is simply useless.

    Let alone the cutting-edge aviation and aerodynamic technologies on the fcnb-2000, Ascendas Group has not fully mastered it. Even if it has mastered it, Ascendas Group will have to stare at the drawings when the entire project enters the engineering implementation stage, because domestic manufacturers can do it.  Speaking of airplanes, even a common pivot inside cannot be made.

    No way, processing such things requires forging, and it cannot be the usual hot forging and die forging, but a precision forging process called multi-directional die forging.

    And this process is the same as other forging processes. The stronger the forging equipment, the better.

    The problem is that only a few manufacturers in China have hundreds of tons of multi-directional die forging equipment. At this level, they can process aircraft pivots of about 50 tons at most, and their performance is not stable. A large aircraft of hundreds of tons will cost at least 5,000.  Multi-directional die forging equipment above 1 ton can be processed.

    Such large heavy equipment is completely blank in the country. Fortunately, now, Zhuang Jianye used one part of it to produce the Tu-204 passenger aircraft, and it was used to produce the Tu-160 strategic bomber in the early years.  An 18,000-ton multi-directional hydraulic forging hydraulic press originally manufactured by the Ural Heavy Machinery Factory with a variable swept wing connected to a pivot was brought over.

    Let alone Huang Feng and Fang Yong, anyone in the aviation industry would be drooling.
