While Colen and Francis were arguing over the purchase of materials.
It is already midnight in the country.
Zhang Xingyang was still in the materials laboratory looking at the new materials Su Xiao and the others had just made.
Nearly two months have passed since the institute cooperated with the WS-10 project.
The materials research team led by Su Xiao has made initial progress, and the materials prepared 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 conducted hundreds of experiments and finally found a material preparation solution suitable for aeroengines."
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, which were full of various terms and formulas, at a speed that ordinary people would think was flipping through a book.
"Well done, Lidya Su."
After Lidya Su was praised, she was very happy, but then she seemed to remember something, frowned and said:
"But the last time I contacted the WS-10 project team, it seemed that their progress was not going particularly smoothly."
Zhang Xingyang closed the folder, raised his eyebrows and asked:
"Tell me specifically what the situation is."
“It is said that there are great difficulties in all aspects, including turbine blade processing, powder metallurgy high-pressure turbine disk, plasma welding, etc.
During the test, blade fractures occurred, and problems such as poor acceleration and surge were serious. "
The various problems Su Xiao mentioned are actually common problems with domestic turbines.
The root cause actually lies in two aspects.
The first is the problem of materials. At this time, the domestic technology of powder metallurgy is actually not particularly advanced. In the previous life, the rise of domestic powder metallurgy still had to wait for more than ten years.
The second is the issue 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 you need to queue up to use them.
This is also an important reason why WS-10 was ultimately not equipped on the J-10.
The engine quality is really not up to par.
For the Air Force, which is in urgent need of third-generation J-10 aircraft for homeland defense, there is simply not enough time to wait for a little improvement in the WS-10 engine.
This is why the Air Force later chose to import the more mature third-generation aircraft engine AL-31F from Mao Xiongjia 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, 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.
The WS-10 engine will not truly mature until more than ten years later, around 10 years into the new century.
"Don't worry about the progress of other scientific research groups in the project. You should try your best to increase the service life of the materials to more than a thousand hours."
Zhang Xingyang thought about the winding and bumpy development road of the WS-10 engine and said.
At this time, the use time of the core components of the engine is about 900 hours for Mao Xiong, while the advanced level in the West is about 3,000 hours.
As for the domestically produced ones, they only have a service life of about 300 hours.
"By the way, how are you doing with the turbine material improvements we asked you 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-turbine pump 500-second experiment failed, Zhang Xingyang told Su Xiao about it.
Let the materials laboratory think of ways to improve the performance of the high-temperature alloy used in turbine blades.
Mentioning this, Su Xiao's beautiful eyebrows also wrinkled, and she looked worried and said:
"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 rocket engines.
Also responsible for cooperation with the WS-10 project.
Many colleagues are almost exhausted. Do you still remember the little girl Han Juan from before? "
Zhang Xingyang nodded and said that he still had some impressions of her.
Su Xiao continued: "When I was working last night, I noticed that her entire face was sallow and she seemed to be in trouble.
After I asked, I learned that she had not slept for more than forty hours in order to prepare new materials. "
Hearing that his colleague was so tired from work, Zhang Xingyang felt a little sorry, so he said:
"Let's do this. You take turns letting the people in the materials laboratory rest for a few days. Tomorrow happens to be the weekend, so let them rest for a few more days."
Su Xiao was naturally very happy when she heard that she could rest. At this time, she blinked her big eyes a little shyly and said:
"Brother Xingyang, are you free 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, which had a headache due to staying up late for a long time, and said a little tiredly:
"Sorry, please help me tell Professor Su that I can't go.
I will go on a business trip to Shengjing tomorrow to discuss the progress of WS-10 with them. "
Su Xiao's originally bright eyes dimmed at this time.
However, Zhang Xingyang did not care about these details and continued to look at the experimental reports of new materials.
"I will bring two samples of the new material to the project team tomorrow. Is there any material left in the laboratory now?"
At this time, Su Xiao no longer felt disappointed before, but returned to his original shrewdness and ability, saying:
"A lot of materials were consumed for performance limit experiments before, but there should be a lot of leftovers prepared at this time."
After Zhang Xingyang thought for a while, he said:
"Well, you and I will go to Shengjing tomorrow, and then you can explain the new materials to them.
I may not be able to explain it clearly on my own. "
In the future, there will definitely be many exchanges with the WS-10 project team about material issues. This time, letting Su Xiao contact the project team in advance will have many benefits for advancing the project progress.
Especially if Zhang Xingyang's ideas are followed, the future engine turbines and blades may also be left to the research institute itself.
Su Xiao didn't think as much as Zhang Xingyang thought. Her eyes lit up and she said happily:
"Really? Then I'll go back and get ready later."
Zhang Xingyang just nodded without saying much and continued to look at the report on hand.
"Brother Xingyang, how long will we go this time? How much clothes should we bring?"
Looking up from the report on hand, Zhang Xingyang said:
"It will take about three or four days, so bringing two or three sets of clothes is probably enough."
