The first-generation Turbofan 10 was simply riddled with flaws.
Many parts are hand-made bit by bit by master workers.
And at this time, the AL-31F has not been introduced from the Damao family in the north.
The avionics control system and some details of the design were not obtained.
As a result, it was difficult for the WS-10 prototype to even be tested on the aircraft. The test pilots at that time almost had a narrow escape before completing the test flight.
The most critical issue here is actually the engine blade problem.
This is also an important reason for engine surge at high speeds.
It's no wonder that at this time, domestic manufacturing, molding and processing techniques for various materials are relatively backward.
There’s nothing really wrong with the WS-10 in terms of design.
But because I have no experience in the fields of new high-temperature resistant materials, directional crystallization precision casting technology, high-temperature powder metallurgy, complex hollow blade precision casting, complex ceramic core manufacturing, titanium alloy forging, microhole processing, coating and special welding.
This resulted in an embarrassing situation of advanced design and backward manufacturing.
However, after the Rocket Research Institute developed new carbon-carbon composite materials with superior performance, high-temperature resistant materials were basically solved.
And compared with the high-temperature superalloys commonly used at this time, carbon-carbon composite materials can not only withstand higher temperatures, but are also at least half lighter than high-temperature superalloys of the same size.
"Dean Zhang, your materials are really incredible."
Chen Jianqing seemed to have been busy doing performance experiments on materials all night long, with two big eye bags and dark circles hanging on his face.
However, the whole person seemed to be in good spirits and said in a happy tone:
"Please forgive me for using the word incredible. In fact, I prefer to call it alien technology!"
At this time, Yingjiang's blockbusters had just begun to be introduced into the country, and all kinds of alien-fighting movies were emerging one after another.
"Alien technology is too exaggerated. Real alien technology must be more powerful than this."
Zhang Xingyang did not lose his self-awareness because of the other party's rainbow fart, but replied calmly.
At this time, Chen Jianqing also regained his composure and returned to the way he was when Zhang Xingyang first saw him.
"Dean Zhang, I really want to thank you this time. If it weren't for your materials, we would probably have to use nickel-based superalloy, which would be difficult to accept in terms of cost and performance."
Zhang Xingyang simply replied: "It's nothing, it's all for the country."
Then Zhang Xingyang remembered something and asked tentatively:
"Can the WS-10 project progress keep up with the equipment of the J-10?"
Speaking of this, Chen Jianqing felt that he had a lot of bitterness to pour out, but in the end he held it back, sighed and said:
"It's probably not very capable. From the attitude of the Air Force, it seems that they can't wait any longer and are preparing to import AL-31F equipment from Damao in the north to the J-10."
Chen Jianqing's mentality didn't seem to collapse, and she was still in the mood to say:
"In fact, there are some benefits to importing AL-31F. After all, it can also allow us to learn from its design."
Zhang Xingyang didn't say anything else at this time. It wouldn't be good if he continued talking, so he patted him on the shoulder and said:
"Everything will be fine. I still have something to do with Mr. Zhang. If you have any questions, please go directly to Lidya Su."
Su Xiao, who was watching the project team members doing tests on the edge of the test bench, looked up at Chen Jianqing and Zhang Xingyang as if telepathically.
Zhang Xingyang smiled when he saw Lidya Su looking at him with some confusion. Then left the materials laboratory.
Arriving at the chief engineer's office in another building, Zhang Zhengjiang happened to be working.
Zhang Xingyang was not polite. After all, although he was physically younger than the other person, he was a little older than the other person in his two lifetimes combined.
And in terms of levels, the two people are actually about the same.
He poured himself a glass of boiled water, took a sip, and then looked at Zhang Zhengjiang, who was still reading the documents.
"General Manager Zhang, have you read the performance report of the new material?"
Zhang Zhengjiang raised the document in his hand, which was the material performance report that just came out this morning:
"I just finished watching it. To be honest, if Jian Qing hadn't personally 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 did not express anything about it. Instead, he turned around and talked about another thing:
"I heard that the engine turbine material problem has not been solved yet?"
Hearing this somewhat sad question, Zhang Zhengjiang lost the smile on his face, but frowned and said:
"The high-temperature-resistant alloys we use now are not up to par, and the operating temperature is too low. This is also a big reason why the thrust force cannot meet the standard."
At this time, Zhang Xingyang began to recommend the Inconel high-temperature alloy that the Rocket Research Institute had previously used on turbine disks.
Although this thing is not as good as the single crystal nickel materials that were later made by laser heating, melting and recrystallization.
But there will still be no problem in maintaining a leading position in the world in the following ten years.
"General Manager Zhang, would you like to try the Inconel superalloy we used on the turbine disk before?
The high temperature resistance is pretty good and the working temperature can reach over 3000 degrees. Although the working life is not very long at high temperatures,
However, with a slight modification and lowering the operating temperature to about 2000 degrees, the working life is estimated to be able to meet the WS-10 requirements. "
The just-released composite material performance test report undoubtedly made Zhang Zhengjiang feel the strength of the Rocket Research Institute in materials research.
So, he asked with a smile:
"Would this be too much trouble for you? We just finished making composite materials for us, and now we have to study high-temperature alloys!"
Speaking of this matter, Zhang Xingyang said somewhat profoundly:
"It's easy to talk about material development and so on, but should we spend money first this time?"
Last time, because of funding issues, they almost made a trick, and they actually used the profits that Factory 703 would have for funding.
If we hadn't found a way to grab a lot of foreign orders at the Canton Fair and earn some US dollars, the institute would probably be unable to survive.
So this time, Zhang Xingyang strongly demanded that the other party send money first and not use the profits of Factory 703 to offset it.
"General Master Zhang, can the funding issue be solved this time?
We can no longer talk about the profits of Factory 703. They are about to start producing special materials for us, and 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 by the authorities have become less and less, and the bulk of it still comes from the Air Force.
If the Air Force hadn't been able to get a little money from the 703 Factory now, it is estimated that the current research groups would have stopped.
However, the project team still had some money at this time, so Zhang Zhengjiang agreed to provide some funds first.
As for the rest, I will give it to you when there are concrete results.
