Just when Colon and Francis were arguing over the issue of material procurement.

It's already midnight in the country.

Zhang Xingyang was still in the materials laboratory looking at the new materials that Su Xiao had just made.

Nearly two months have passed since the Institute and the WS-10 project cooperated.

The materials research team led by Su Xiao has made initial progress, and the prepared materials basically meet the requirements of aviation materials.

Zhang Xingyang took the latest material performance test report and listened to Su Xiao's report while flipping through it.

"According to the requirements of the WS-10 project team, we carried out hundreds of experiments, and finally found a material preparation scheme suitable for aero engines."

At this time, Su Xiao handed over a dozen documents on the preparation process of aviation materials.

Zhang Xingyang took the materials and looked at these documents full of various terms and formulas at the speed of ordinary people thinking that they were turning books.

"Good job, Su Xiao."

After Su Xiao was praised, the whole person was very happy, but then as if he remembered something, he frowned and said:

"But the last time I contacted the WS-10 team, it didn't seem to be going very well."

Zhang Xingyang closed the folder, raised his eyebrows and asked:

"Tell me more about the situation."

"It is said that there are great difficulties in all aspects, such as turbine blade processing, powder metallurgy high-pressure turbine discs, plasma welding, and so on.

During the test, there was a scene of blade breakage, and problems such as poor acceleration and surge were serious. ”

The various problems Su Xiao said are actually common problems in domestic turbines.

The root cause is actually a two-pronged problem.

The first is the problem of materials, powder metallurgy at this time the domestic technology is actually not particularly passable, the rise of domestic powder metallurgy in the previous life or to wait until more than ten years later.

The second is the problem of processing, at this time, the multi-axis high-precision machining center is still very scarce in China, only a few and need to queue up to be able to use.

This is also an important reason why the WS-10 was not able to equip the J-10 in the end.

The quality of the engine is really not up to par.

For the Air Force, which urgently needs the third-generation J-10 for homeland defense, there is simply not so much time to wait for the WS-10 engine to be improved little by little.

This is why the Air Force later chose to import the more mature third-generation aircraft engine AL-31F from the Mao Xiong family in the north.

Although the AL-31F still has many problems compared with many Western aero engines, such as short service life, short single maintenance time, small thrust and other shortcomings.

But compared to this point in time, the WS-10, which basically cannot be used as a qualified engine, is still much better.

And the WS-10 engine will really mature until more than a decade later, to about 10 years in the new century.

"Regardless of the progress of the other research groups in the project, you should try to increase the service life of the materials to more than 1,000 hours."

Zhang Xingyang thought about the winding and bumpy research and development road of the WS-10 engine and said.

At this time, the service time of the core components of the engine is about 900 hours, while the advanced level of the West is about 3,000 hours.

As for the domestic one, it probably only has a service life of 300 hours.

"By the way, how are the turbine material improvements that you were asked to do now?"

Zhang Xingyang thought of the turbine on his own rocket engine from the turbine on the WS-10, and suddenly asked.

Some time ago, after the gas generator-turbopump 500-second experiment failed, Zhang Xingyang told Su Xiao about it.

Let the materials lab figure out how to improve the performance of the superalloys used in turbine blades.

At the mention of this, Su Xiao's good-looking eyebrows also wrinkled, and the whole person looked sad and said:

"There's not a lot of work yet, there's so much work in the materials lab right now, and we don't just have to deal with the various materials in the rocket engine.

He will also be responsible for cooperation with the WS-10 project.

Many colleagues are already tired and lying down, do you still have an impression of the little girl Han Juan before? ”

Zhang Xingyang nodded, indicating that he still had some impressions of her.

Su Xiao continued: "When I was working last night, I found that her whole face was sallow, and she didn't seem to be able to do it anymore.

After I asked, I found out that she hadn't closed her eyes for more than forty hours in order to prepare the new material. ”

Hearing that his colleagues were so tired from work, Zhang Xingyang was also a little upset, so he said:

"In this way, you take turns to give the people in the materials lab a few days off, and tomorrow is the weekend, so let them rest for a few more days."

Hearing that he could rest, Su Xiao was naturally very happy, and at this time, he blinked his eyes a little shyly and said:

"Brother Xingyang, do you have time tomorrow, I want to invite you to my house for a meal, and my dad also wants to have a meal with you!"

Zhang Xingyang rubbed his forehead, which had a headache because of staying up late for a long time, and said a little tired:

"I'm sorry, please help me talk to Professor Su, I can't go.

Tomorrow I'm going on a business trip to Shengjing to discuss the progress of WS-10 with them. ”

Su Xiao's originally bright eyes also dimmed at this time.

However, Zhang Xingyang didn't care about these details, but continued to look at the experimental report of the new material.

"I will bring two samples of new materials to the project team tomorrow, are there any materials left in the laboratory?"

At this time, Su Xiao did not have the previous loss, but regained his original shrewdness and ability, and said:

"The material used to do a lot of performance limit experiments, but at this time, there should be a lot of leftovers."

After thinking about it, Zhang Xingyang said:

"Well, you and I will go to Shengjing tomorrow, and then you can explain to them about the new materials.

I may not be able to explain it very clearly. ”

After that, there will definitely be many exchanges with the WS-10 project team about the materials, and this time let Su Xiao contact the project team in advance, which will have a lot of benefits for the progress of the project.

Especially if according to Zhang Xingyang's idea, the subsequent engine turbines and blades may also have to be handed over to the research institute itself.

Su Xiao didn't think as much as Zhang Xingyang thought, her eyes lit up, and she said a little happily:

"Really, then I'll go back and get ready."

Zhang Xingyang just nodded, didn't say anything too much, and continued to look at the report at hand.

"Brother Xingyang, how long are we going to go this time? How many clothes do you have to bring? ”

Raising his head from the report at hand, Zhang Xingyang said:

"It will take about three or four days, and it is estimated that it is enough to bring two or three sets of clothes."
