Chapter 732 It¡¯s all about subversion

    No wonder this old expert from the energy department is like this. In fact, the values ??on the detection equipment are exactly the same as the basic metallographic composition of the materials on both sides.

    In other words, the components of two different materials are processed by the alternative nb-250 to form an integrated combination with a magical effect.

    If you haven¡¯t seen it with your own eyes, it would be no exaggeration to say that the two materials grow together naturally.

    So that all the data characteristics are no less than the high strength and high reliability of the material itself. Even after a little polishing, even the welds cannot be observed with testing equipment, let alone the naked eye.

    " Such a blisk is said to be integrally processed using five-axis and seven-axis linkage, which will definitely make people believe it 100%.

    But the problem is that five-axis and seven-axis linkage can only process a single alloy material, but the integral blade in front of you is made of two different titanium materials.

    ? One is a titanium alloy, and the other is a carbon fiber-reinforced titanium-based composite material.

    No matter how strong the five-axis and seven-axis linkage are, it is impossible to combine the two materials for integrated processing. More importantly, the five-axis and seven-axis linkage can be used to make solid blades or hollow blades, with a hollow center and a closed outer surface.  The five-axis and seven-axis linkage of string hollow blades is really more than enough.

    The important development direction of aviation engines and gas turbines in the future is integral blisks and wide-chord hollow blades. This will not only reduce the overall quality of aviation engines and gas turbines, but also improve their service life. More importantly, the use of these two  The compressor efficiency of this technology will be doubled, which will increase the air compression ratio, increase the intake air flow, and promote the complete combustion of fuel.

    Putting it on an aircraft engine will increase the engine thrust; applying it to a gas turbine will improve the thermal conversion efficiency of the gas turbine.

    The problem is that it is very difficult to combine these two good technologies for application. If they are produced separately, the overall effect will not be achieved; if they are operated as a whole, only one kind of material can be used, and local optimization cannot be achieved.  .

    What¡¯s more, there is a fatal processing problem in the end.

    Therefore, aircraft engine giants such as GE, Rolls-Royce and Pratt & Whitney generally follow two technical routes, one is the integrated route headed by GE.

    That is to use the super material and metallurgical technology of the United States to produce high-quality titanium alloy, and then use casting technology to make a hollow integral compressor blank, and finally use a seven-axis linkage machine tool for integrated machining.

    The other is a segmented combination technology route with Pratt & Whitney as the core, that is, the wide-chord hollow blades and the rotor are produced separately, and then the two are combined using processes such as vacuum diffusion welding or vacuum electron beam welding.

    The two technical routes have their own advantages and disadvantages, but without exception the costs are surprisingly high.

    Needless to say, whether it is a five-axis or seven-axis linkage, it costs money. If the previous overall casting process is included, the cost of a whole blisk is almost as much as that of a previous jet aircraft.

    Pratt & Whitney's seems to be good, but the problem is that the welding process is extremely complicated. It either requires a vacuum environment or expensive fillers as media. The problem is that with these things, the yield rate is not high, and the high scrap rate indirectly drives up the cost.  .

    Because of this, these high-end technologies are basically used by the major giants to buy only the right military products regardless of price. After all, the military is pursuing leapfrog technological advantages, and money and other things have nothing to do with winning.  It's nothing in comparison, especially the wealthy US military, which has a wealthy obsession in this regard.

    ¡° However, Ascendas Group actually solved this technical problem that even foreign aviation and gas turbine giants had a headache with one piece of equipment.

    No fancy five-axis or seven-axis linkage, no complicated welding equipment, just a method similar to friction welding is used to achieve the best technical effect of the overall blisk. This ability is really

    "We at Ascendas Group have never been the kind of company that just follows others and imitates them, let alone take other people's things and accumulate them like children putting together building blocks to be complacent and feel that our abilities are limitless. What we do  It is always subversive. Without this backbone, we would still be talking about the four modernizations and making the country rich and the people strong."

    Just when the experts in the energy department marveled at the disruptive process capabilities displayed by Ascendas Group¡¯s nb-250, Zhuang Jianye¡¯s words rang out again in the workshop.

    It immediately made many experts look embarrassed, especially Cai Weiguo and others who had previously ridiculed Zhuang Jianye and Ascendas Group. Their faces turned blue and red.

    It was obvious that what Zhuang Jianye was talking about was the Jinling Steam Turbine Factory, which had given them benefits. This made Cai Weiguo, who originally wanted to take this opportunity to introduce the nb-250 back to the Jinling Steam Turbine Factory, not even have the least chance to speak.

    ?Because Zhuang Jianye's words are not belittling Jinling Steam Turbine Factory, but he does not take Jinling Steam Turbine Factory seriously at all. In other words, where Zhuang Jianye is, Jinling Steam Turbine Factory and other joint venture factories that cooperate with foreign giants are not even talking to him.  They have no qualifications to be equals.

    ¡°In this case, the leaders and experts of the energy department who have benefited from the joint venture and squeezed out the Ascendas Group are not qualified to comment here.

    ??In other words, Zhuang Jianye came to receive you to give you face. Whether you come or not has nothing to do with Ascendas Group. If you like to lick the butts of foreign giants, you can lick them. Ascendas Group will not accompany you.

    Everyone present is not a fool. If you still can¡¯t understand the meaning of Zhuang Jianye¡¯s words, then you don¡¯t have to sit in your current position. Therefore, including the leaders of the energy department, everyone in the entire research team has an expression on their face.  They're all terribly ugly.

    Even the head of the headquarters didn't look good. He couldn't help it. This time the energy department came to investigate and he was the one who invited people to come here without giving up his old face. As a result, Zhuang Jianye not only refused to give him face, but also said such cruel things. What did this bastard want to do?  ?  Are you going to give up the industrial gas turbine business completely?

    "Comrade Zhuang Jianye, if I understand correctly, did you really criticize our department's actions just now?" Just when the head of the headquarters was thinking about how to help Zhuang Jianye recover, the leader of the energy department suddenly laughed and asked.

    Zhuang Jianye also smiled: "Boss, look at what you said, how am I qualified to criticize your department? I am a businessman, I am here as a customer, and we are talking about business. Let's have a drink and have a good time. If not, we can still make friends.  no."

    If the previous words make everyone think that Zhuang Jianye is crazy, then everyone present will think that this guy is crazy. This is tantamount to completely severing cooperation with the energy sector and severing himself from the market. Zhuang Jianye really thinks that he has  The disruptive nb-250 equipment can surpass the market and dare to challenge the energy department of a large user of gas turbines?

    What a joke!
