The original turbofan ten can be said to be full of problems.

Many parts are made by hand by the master of the worker little by little.

And at this time, the AL-31F has not been introduced from the Da Mao family in the north.

Didn't get the avionics control system, and some of the details of the design.

As a result, the prototype of the WS-10 was difficult to even test on board, and the test pilots at that time completed the test flight almost without a lifetime of death.

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

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

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

There is nothing wrong with the WS-10 in terms of design.

However, because it has not been exposed to new high-temperature resistant materials, directional crystallization precision casting process, high-temperature powder metallurgy, complex hollow blade precision casting, complex ceramic core manufacturing, titanium alloy forging, microhole machining, coating and special welding.

This has created an embarrassing situation of advanced design and backward manufacturing.

However, after the Rocket Research Institute developed a new 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 composites can not only withstand higher temperatures, but also have at least half the weight of high-temperature superalloys of the same size.

"Dean Zhang, your materials are really incredible."

Chen Yuanqing seems to have been busy experimenting with the performance of materials all night without sleeping, with two big eye bags and dark circles on his face.

However, the whole person's spirit seemed to be very good, and he said in a very happy tone:

"Forgive me for using the word incredible, I'd actually prefer to call it alien technology!"

At this time, Eagle Sauce's blockbusters had just begun to be introduced into China, and all kinds of films fighting aliens were emerging.

"Alien technology is too exaggerated, and the real alien technology must be more powerful than this."

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

At this time, Chen Jianqing also regained his composure and changed back to the way Zhang Xingyang was when he first met him.

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

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

Immediately afterwards, Zhang Xingyang remembered something, so he asked tentatively:

"Will the project progress of the WS-10 still be able to catch up with the equipment of the J-10?"

Speaking of this, Chen Yuanqing felt that he had a lot of bitter water to pour, but in the end he held back, sighed and said:

"I guess it's not very good, listening to the attitude of the Air Force, it seems that I can't wait, and I'm ready to import AL-31F equipment from Da Mao in the north to J-10."

Chen Yuanqing's mentality doesn't seem to have collapsed, and he is still in the mood to say:

"In fact, the import of AL-31F is still a bit beneficial, after all, it can also allow us to learn from its design."

Zhang Xingyang didn't say anything at this time, and it was basically not good to continue to talk about it, so he patted him on the shoulder and said:

"It's going to get better, I still have something to find 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 on the side of the test bench, looked up at Chen Jianqing and Zhang Xingyang as if telepathically at this time.

Zhang Xingyang saw Su Xiao looking at him with some confusion and smiled. Then he left the materials lab.

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

Zhang Xingyang was not polite, after all, although his body age was younger than the other party, he was a little older than the other party in his two lives combined.

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

poured himself a glass of boiled water, took a sip, and then looked at Zhang Zhengjiang, who was still reading the documents.

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

Zhang Zhengjiang lifted the document in his hand, which was the material performance report that had just come out this morning:

"I just finished reading it, to be honest, if this performance test hadn't been done by Jianqing himself, I would definitely not have believed it.

These figures are exaggerated! ”

Zhang Xingyang spread his hands and did not express anything about it, but turned his head and said another thing:

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

Hearing this somewhat sad question, Zhang Zhengjiang didn't have the previous smile on his face, but frowned and said:

"The high-temperature resistant alloy we use now is not up to standard, and the working temperature is too low, which is also a big reason why the thrust cannot meet the standard."

Zhang Xingyang began to recommend at this time that the Rocket Research Institute had previously applied Inconel superalloys on turbine disks.

Although this thing is not as good as the monocrystalline nickel materials that were later melted and recrystallized by laser heating.

However, in the following ten years, there is no problem in maintaining the leading level in the world.

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

The high temperature resistance is not bad, the working temperature can reach more than 3000 degrees, although the working life is not very long in the high temperature state,

However, if the working temperature is reduced to about 2000 degrees, the working life is estimated 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, with a smile, he asked:

"Won't that be too much of a hassle for you? We have just finished making composite materials, and we are going to study superalloys! ”

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

"It's easy to talk about material development or something, but shouldn't you pay for it first this time?"

Last time, because of the problem of funding, they almost put it together, and they actually used the profits of the 703 factory that I don't know when they will be able to use it as a fund.

If it weren't for finding a way to grab a lot of foreign orders at the Canton Fair and earn some dollars, it is estimated that the 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 Factory 703 to deduct it.

"Chief Master Zhang, this time the matter of funding can be solved!

We can't talk about the profits of the 703 factory anymore, they are about to start producing special materials for us, and the profits will definitely come down! “

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

If it weren't for the fact that the Air Force could get a little money from the 703 factory now, it is estimated that the various research groups would have to stop.

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

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