A big country of aerospace with black technology

Chapter 33 Recent Developments in WS-10

Just as Collen and Francis were arguing over the procurement of materials.

It's already midnight in the country.

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

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

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

Zhang Xingyang held the latest material performance test report and read it while listening to Su Xiao's report.

"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 about the preparation process of aviation materials.

Zhang Xingyang took the materials, and flipped through the documents full of various terms and formulas at a speed that ordinary people think of as flipping through books.

"Good job, Su Xiao."

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

"But when I contacted the WS-10 project team last time, it seemed that they were not going very well."

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

"Tell me exactly what happened."

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

During the test, there was a scene where the blade broke, and problems such as poor acceleration and surge were very serious. "

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

The root cause is actually two problems.

The first is the issue of materials. At this time, the domestic technology of powder metallurgy has not yet passed the test. The rise of domestic powder metallurgy still has to wait more than ten years later in the previous life.

The second is the problem of processing. At this time, multi-axis high-precision machining centers are still very scarce in China. There are only a few of them and they need to be queued to be used.

This is also an important reason why WS-10 was not able to be equipped with 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 a little improvement of the WS-10 engine.

This is why, later, the Air Force chose to import the more mature third-generation engine AL-31F from Maoxiong's family in the north.

Although AL-31F still has many problems compared with many western aero engines, such as short service life, short single maintenance time, low 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 have to wait for more than ten years to be truly mature, and it will be about 10 years into the new century.

"Don't worry about the progress of the other scientific research groups of 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 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 for Mao Xiong, while the advanced level of the West is about 3,000 hours.

As for the domestic ones, they only have a service life of about 300 hours.

"By the way, how is the improvement of the turbine material that you were asked to do before?"

Zhang Xingyang suddenly asked from the turbine on the WS-10 to the turbine on his own rocket engine.

Some time ago, after the gas generator-turbo pump experiment failed for 500 seconds, Zhang Xingyang told Su Xiao about it.

Let the materials laboratory think of a way to see if it can further improve the performance of the superalloy used in turbine blades.

Mentioning this, Su Xiao's beautiful eyebrows also frowned, and he said sadly:

"There are not many results yet. There is too much work in the materials laboratory at present. We not only have to solve various materials in the rocket engine.

Also responsible for the cooperation with WS-10 project.

Many colleagues are almost exhausted. Do you still remember the little girl Han Juan from before? "

Zhang Xingyang nodded to express 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 seemed to be dying.

After I asked, I found out that in order to prepare new materials, she had not closed her eyes for more than forty hours. "

Hearing that his colleague was so tired from work, Zhang Xingyang also felt a little sorry, so he said:

"How about this, you take turns to let the people in the material laboratory rest for a few days, it happens that tomorrow is the weekend, let them rest for a few more days."

Hearing that he was able to rest, Su Xiao was naturally very happy. At this time, he blinked his big eyes shyly and said:

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

Zhang Xingyang rubbed his forehead that had a headache from staying up late for a long time, and said a little tiredly:

"Sorry, please tell Professor Su for me, I can't go.

Tomorrow I will go on a business trip to Shengjing to discuss the progress of WS-10 with them. "

Su Xiao's originally piercing eyes dimmed at this moment.

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

"I will bring two samples of the new material to the project team tomorrow. Is there any material left in the laboratory?"

At this time, Su Xiao didn't have the previous loss, but recovered the original shrewdness and said:

"A lot of materials were consumed for performance limit experiments before, but at this time there should be a lot of leftovers."

After Zhang Xingyang thought about it, he said:

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

I may not be able to explain it myself. "

Afterwards, I will definitely need many exchanges with the WS-10 project team about the material issues. This time, it will be beneficial for Su Xiao to contact the project team in advance, which will help the progress of the project.

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

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

"Really, then I will go back and prepare well."

Zhang Xingyang just nodded, without expressing too much, and continued to look at the report at hand.

"Brother Xingyang, how long are we going this time? How many clothes do we need to bring?"

Looking up from the report at hand, Zhang Xingyang said:

"It will take about three or four days. It is probably enough to bring two or three sets of clothes."
