A big country of aerospace with black technology

Chapter 35 WS-10 Improvements

The first-generation turbofan ten can be said to be full of problems.

Many parts are hand rubbed out bit by bit by master workers.

And at this time, the AL-31F has not been imported from Da Mao's house in the north.

I didn't get the avionics control system and some details about the design.

As a result, the prototype of the WS-10 was even difficult to test on the machine. The test pilot at that time almost completed the test flight after a near death.

The most critical problem among them is actually the problem of the blades of the engine.

This is also an important reason for the engine to surge at high speeds.

It's no wonder that at this time, the manufacturing and processing techniques of various materials in China are relatively backward.

There is nothing wrong with the design of WS-10,

But because of new high temperature resistant materials, directional crystal precision casting process, high temperature powder metallurgy, complex hollow blade precision casting, complex ceramic core manufacturing, titanium alloy forging, micro hole processing, coating and special welding, etc.

This has resulted in the embarrassing situation of advanced design and backward manufacturing.

However, after the Rocket Research Institute developed a new type of carbon-carbon composite material with superior performance, the high-temperature resistant material was basically solved.

Moreover, compared with the high-temperature superalloys commonly used at this time, carbon-carbon composite materials can not only withstand higher temperatures, but also have a weight that is at least half lighter than high-temperature superalloys of the same size.

"Dean Zhang, your materials are really incredible."

Chen Jianqing seemed to be busy doing performance experiments on materials all night without sleep, and there were two big eye bags and dark circles on his face.

However, the spirit of the whole person seems to be in a good state, and he said in a very happy tone:

"Please forgive me for using the word incredible, in fact, I prefer to call it alien technology!"

At this time, Yingjiang's blockbuster movies had just begun to be introduced into China, and various movies about fighting aliens were emerging in an endless stream.

"The alien technology is too exaggerated. The real alien technology must be better than this."

Zhang Xingyang did not lose his self-knowledge because of the other party's rainbow fart, but replied calmly.

At this time, Chen Jianqing also regained his composure, and changed back to the way Zhang Xingyang had just seen him before.

"Dean Zhang, thank you very much this time. If it weren't for your materials, we would probably have to use nickel-based superalloys, which would be unacceptable in terms of cost and performance."

Zhang Xingyang replied simply: "It's nothing, it's all for the country."

Then Zhang Xingyang remembered something, so he asked tentatively:

"Can the progress of the WS-10 project catch up with the J-10?"

Speaking of this, Chen Jianqing felt that he had a lot of bitterness to pour out, but finally held back, sighed and said:

"It probably won't be able to. Judging from the attitude of the Air Force, it seems that it can't wait any longer. It plans to import AL-31F equipment from Da Mao in the north to equip the J-10."

Chen Jianqing's mentality didn't seem to collapse yet, and he still had the mood to say:

"In fact, importing AL-31F is still a bit beneficial, after all, it can also let us learn from the design inside it."

Zhang Xingyang didn't say anything else at this time, and it would basically be bad if he continued, so he patted him on the shoulder and said:

"Everything will be fine. I still have something to ask Chief Master Zhang. If you have any questions, go directly to Su Xiao."

Su Xiao, who was watching the project team members doing the test, looked up at Chen Jianqing and Zhang Xingyang as if telepathically.

Seeing Su Xiao looking at him with some doubts, Zhang Xingyang smiled. Then left the materials laboratory.

When they came to the chief teacher's office in another building, Zhang Zhengjiang happened to be working.

Zhang Xingyang was not too polite. After all, although he was physically younger than the other party, he was a little older than the other party in the sum of his two lifetimes.

And in terms of level, the two are actually about the same.

I poured myself a glass of plain water, took a sip, and then looked at Zhang Zhengjiang who was still reading the document.

"Master Zhang, have you read the performance report of the new material?"

Zhang Zhengjiang raised the document in his hand, it was the material performance report just released this morning:

"I just finished reading it, and to be honest, if Jianqing hadn't led someone to do this performance test, I definitely wouldn't have believed it.

These data are too exaggerated! "

Zhang Xingyang spread his hands and didn't say anything about it, but turned around and talked about another thing:

"I heard that the engine turbine material problem has not been solved yet?"

Hearing this sad question, Zhang Zhengjiang no longer had the previous smile on his face, but frowned and said:

"The high-temperature resistant alloys we are using now are not up to standard, and the working temperature is too low. This is also a major reason why the thrust cannot meet the standard now."

At this time, Zhang Xingyang began to recommend the Inconel superalloy that the Rocket Research Institute had previously applied to the turbine disk.

Although this thing is not as good as those single crystal nickel materials that were later melted and recrystallized by laser heating.

However, there is still no problem in maintaining the leading level in the international arena in the next ten years.

"Master Zhang, do you want to try the Inconel superalloy we used on the turbine disk before?

The high temperature resistance performance is not bad, the working temperature can reach above 3000 degrees, although the working life is not very long at high temperature,

However, with a slight change, the working temperature is reduced to about 2000 degrees, and the working life is estimated to be able to meet the requirements of WS-10. "

The just-released composite material performance test report undoubtedly made Zhang Zhengjiang feel the strength of the Rocket Research Institute in material research.

So he asked with a smile:

"Will this be too much trouble for you? Just finished making composite materials for us, and you are asked to study superalloys!"

Speaking of this matter, Zhang Xingyang said with some deep meaning:

"Material development is easy to talk about, but this time, shouldn't we pay first?"

Last time, because of the funding problem, they were almost set up by them, and they actually used the profits that the 703 factory will have after they don't know when they will be funded.

If it hadn't been for finding a way to grab a lot of foreign orders at the Canton Fair and earn some dollars, it is estimated that the research institute would not be able to survive.

So this time, Zhang Xingyang strongly asked the other party to pay first, and could no longer use the profits of the 703 factory to offset the deduction.

"Master Zhang, the funding issue can be resolved this time!

We can no longer talk about the profits of the 703 factory. They will start producing special materials for us soon, and the profits will definitely drop! "

At this time, Zhang Zhengjiang also felt a little embarrassed, but he couldn't help it. WS-10 has not made much progress. In recent years, the funds allocated from above have become less and less, and most of them come from the Air Force.

If it weren't for the Air Force's ability to get a little money from the 703 factory, it is estimated that all the current research groups will stop.

However, the project team still had a little money at this time, so Zhang Zhengjiang still agreed to pay part of the funds first.

As for the rest, I will give it when there are concrete results.
