Take Off My Aviation Era

It's no wonder that this old expert in the energy department is like this. It is true that the values ​​on the detection equipment are in good agreement with the basic metallographic composition of the materials on both sides.

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

If you don't see it with your own eyes, it is not an exaggeration to say that the two materials grow together.

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

Such an integral blisk is said to be integrated with five-axis and seven-axis linkage for integrated processing, which will definitely make people 100% believe it.

The problem is that the five-axis and seven-axis linkage can only process a single alloy material, but the integral blade in front of it uses 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 linkages are, it is impossible to combine the two materials for integrated processing. More importantly, the five-axis and seven-axis linkages can be made of solid blades or hollow blades, with a hollow center and a closed surface. The linkage of the five-axis and seven-axis of the hollow blades of the string is really not enough.

The important development direction of the aviation engine and gas turbine in the future is the integral blisk and wide-chord hollow blades. This can not only reduce the overall quality of the aviation engine and the gas turbine, but also increase the service life, and more importantly, use these two The compressor efficiency of the technology will be doubled to increase the air compression ratio, increase the intake air flow, and promote the full combustion of fuel.

Putting it on the aviation engine in this way increases the engine thrust; applying it to the gas turbine can improve the heat conversion efficiency of the gas turbine.

The problem is so good. It is very difficult to combine two technologies to play the role of application. Separate production will not achieve the overall effect; to operate as a whole, only one material can be used, and partial optimization cannot be achieved. .

What's more, there is a terrible processing problem at the end.

Therefore, aviation giants such as ge, Luoluo, and Pratt & Whitney generally follow two technical routes, one is an integrated route headed by ge.

That is, the use of American superior materials and metallurgical technology to produce high-quality titanium alloys, 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, wide-chord hollow blades are produced separately from the rotor, and then the two are combined by vacuum diffusion welding or vacuum electron beam welding.

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

Needless to say, whether it is a five-axis or seven-axis linkage, it is money. If you count the previous overall casting process, the cost of an integral blisk will almost catch up with the previous jet.

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

Because of this, these high-tech giants are basically used to buy the right military products, regardless of the price. After all, the military pursues leap-forward technological advantages, and money and so on. It's nothing compared to that, especially the rich and powerful US military, which has a local tyrant-like obsession.

However, it is such a technical problem that even the foreign aviation giants have headaches, and Tengfei Group has solved it with a single device.

There is no high five-axis or seven linkage, and no complicated welding equipment. It only uses a method similar to friction welding to achieve the best technical effect of the overall blisk. This ability... is really...

"Our Ascendas Group has never been the kind of company that just follow people behind their **** to imitate, let alone take other people's things like a child trying to build blocks and get complacent, feel that our ability is too big, we do It will always be subversive. If there is no such backbone, what else will we talk about the four modernizations, and what will we talk about the prosperity of the country and the strong people."

Just as experts in the energy sector were amazed by the disruptive technological capabilities of the nb-250 of Ascendas Group, Zhuang Jianye's words rang out again in the workshop.

Immediately, many experts were embarrassed, especially Cai Weiguo, who had ridiculed Zhuang Jianye and Tengfei Group, had their faces green and red.

Obviously, what Zhuang Jianye said was the Jinling Steam Turbine Factory that benefited them. This made Cai Weiguo, who originally wanted to use this opportunity to introduce the nb-250 back to Jinling Steam Turbine Factory, didn't even have the least chance to speak.

Because Zhuang Jianye’s words are no longer to belittle Jinling Turbine Factory, but Jinling Turbine Factory is completely ignored. That is to say, in Zhuang Jianye, Jinling Turbine Factory and other joint ventures that cooperate with foreign giants even talk to him. There is no qualification to sit on an equal footing.

That being the case, the leaders and experts of the energy department of Ascendas Group who have benefited from the joint ventures and run on them are even less qualified to comment here.

In other words, Zhuang Jianye came to receive it to give you face, and you have nothing to do with Tengfei Group. If you like to lick the **** of foreign giants, you will lick it. Tengfei Group will not accompany you.

The people present are not fools. If Zhuang Jianye’s remarks still don’t make sense~www.wuxiaspot.com~, you don’t need to sit in your current position. So, including the energy department leaders, the entire research team is One is counted as one, and his face is terribly ugly.

Even the head of the headquarters doesn’t look pretty. There’s no way. This time the energy department came to investigate and invited people to come over with his old face. As a result, Zhuang Jianye not only didn’t give face, but he also said such utterly words, what the **** wanted to do ? Want to completely abandon the industrial gas turbine business?

"Comrade Zhuang Jianye, if I understood correctly, you really criticized our department's approach just now?" When the head of the headquarters was thinking about how to help Zhuang Jianye recover, the energy department leader suddenly laughed and asked.

Zhuang Jianye also smiled: "Leader you see what you are saying, how can I be qualified to criticize your department? I am a business enterprise, I am a guest, and I am talking about business. It has become that we can make friends with each other. No."

If the previous words make everyone think that Zhuang Jianye is nervous, then one of the people present thinks that this guy is crazy. This is tantamount to completely severing cooperation with the energy sector and the market. Zhuang Jianye really thinks he has it. The disruptive nb-250 equipment can outperform the market and dare to challenge the energy sector that uses large gas turbines?

What a joke!
