The ups and downs of life in the Siheyuan

Being stared at by the old general's stern eyes, both of them were confused.

My eyes wandered around for a long time, but I couldn't find anyone to ask for help.

The old general sighed and stopped paying attention to the two of them.

Turning to look at Li Yuan, a smile slowly appeared on his face.

"Xiao Li, your modification is good, but do you have any plans to improve the radiator?"

"Chief, let me try."

"Little boy," he turned to the boy representative.

"Xiao Li, if you need something, you have to do your best to satisfy it."

"Yes, Chief!"

"Xiao Li, try it boldly and I'll tell you the truth." The old general was very pleased.

The successful test run gave him full confidence in the turbojet-6 modification.

When Lei Gong and Liu Gong rushed to the base, everyone in the base had left.

There were only two young men waiting for them.

After listening to the report, they discussed it and found the person in charge of the base together.

"There is nothing we can do. We don't know where Xiao Li works. You can contact Representative Tong. He is the one who contacts you every time."

The person in charge of the base was somewhat dissatisfied with the two, but still told the truth.

The two of them finally got through to Representative Tong.

"I'm sorry, Li Yuan's unit keeps confidentiality. If you need it, you can apply to your superiors." Representative Tong directly rejected their request.

"In that case, please tell Representative Tong the name of Comrade Li Yuan's unit." Liu Gong, who was holding the phone, suppressed his anger.

"Sorry, confidentiality. If there is nothing else, I will hang up."

Liu Gong got angry and slapped the table.

"Isn't he just a bad representative? He doesn't know anything when asked."

The child worker who heard the entire conversation on the speakerphone also had a bad look on his face.

Although their aircraft have a high failure rate, they are currently the only domestically produced fighters.

Wherever they went, they were greeted warmly.

This time the old general was dissatisfied with them, it was that boy who did it.

The two of them had nowhere to vent their frustration at being robbed of their limelight.

Now, knowing that the other party is a unit with such a high level of confidentiality, they are even more depressed.

"What unit actually keeps secrets from us?" Lei Gong thought thoughtfully.

"Go back and report to the leader to see if there is anything he can do," Liu Gong said.

"That's all it can do."

Twenty days later, one night, Representative Tong transported four brand-new turbojet-20 engines into the repair shop.

In the past few days, Li Yuan and Xiao Gong worked together to process the necessary parts.

Here is a domestic machine tool C620-1 from Shenyang No. Machine Tool Factory.

Li Yuan made improvements to it. One was to replace some parts and improve the machining accuracy.

All parts that need to be replaced have been improved or reprocessed.

The electronic control module was waterproofed and heat-insulated, and 6 sets were made.

As soon as the four sets of engines arrived, the two began to dismantle and upgrade them.

In order to increase the duration of the test, Li Yuan used telekinesis to scan and inspect each component and replace defective components.

Especially the 9-stage blades in the press, he inspected them one by one to ensure that no damaged blades appeared inside.

When all the components were installed, he looked at the 10 flame combustion chambers (also called flame tubes) and fell into deep thought.

Now the biggest weakness of the entire engine is here, and he must make changes.

I rummaged through my memory and finally chose the optimized solution for the turbine and flame tube.

If these two issues are not addressed, the service life of the refurbishment cannot be truly improved.

Li Yuan chose the 1970 improvement plan of the Shenyang Aviation Engine Factory. Through the use of more than 20 improvements such as Aiki membrane gas tube and floating heat shield.

This improvement will completely solve the problem of the life of the turbine and flame barrel.

Li Yuan silently copied his homework while paying tribute to his seniors.

The changes this time are larger. All the hydraulic valves in the past have been replaced by solenoid valves, which overall looks more orderly.

More than a month has passed, and Liu Gong and Lei Gong have already given up the idea of ​​looking for Li Yuan.

After they reported to the factory leaders respectively, the two factories took it very seriously.

The two men were recalled, led by the deputy director, and once again went to Kyoto.

The base leaders were overwhelmed and contacted the old general.

"Be patient," the old general said to the two of them on the phone.

The two deputy factory directors came with a mission, how could they go back.

They took people with them to start surveying and mapping the turbojet 6 modified prototype that was scrapped before testing.

When they had just completed the survey and were confused about where the control unit was originally placed, Li Yuan came to the base again with four brand-new engines.

When they found out that the shameless young man was the one who embarrassed their former core engineer, they looked incredulous.

After reacting, they excitedly introduced themselves to Li Yuan, which shocked Li Yuan.

"Hello, nice to meet you," Li Yuan shook hands with them politely.

"Comrade Li is really young and promising. We old guys can't keep up with you young people."

"You are so humble. We have only made slight progress by standing on your shoulders." Li Yuan followed politely.

"No, no, no, the flight control system has always been our dream. If you can realize it, it is an insurmountable gap for us. Thanks to you."

The two deputy factory directors continued to praise him.

"You are in love by mistake. The control module and the flight control system are far different," Li Yuanqing said.

"Guys, let's talk during the lunch break. It's time to get to work." Representative Tong rudely interrupted these useless pleasantries.

"I'm sorry, I'm going to work first." Li Yuan smiled apologetically.

"You are busy, you are busy".

This time, two engines were tested at the same time, and the control method remained unchanged. The test driver last time easily got started.

In order not to affect each other, the two engines are more than 50 meters apart.

Both engines started normally without any accidents and ran smoothly.

After lunch, Li Yuan was stopped by two deputy factory directors.

"Comrade Li, I apologize to you for LiuGong's inappropriate remarks last time. They cannot represent the ** Aircraft Factory. Our factory still looks forward to cooperating with you."

"Comrade Li, I also apologize to you for being a thunder worker. Please don't get along with them."

The two deputy directors had a very low profile, which made Li Yuan a little flattered.

Ordinarily, they shouldn't be like this.

Li Yuan didn't bother to guess. As long as they asked for anything, they would ask for it.

"I never took it seriously. It was all a technical discussion. Everyone has their own insistence. This is normal."

"Let me just say, Comrade Li is someone who does great things at first sight."

"That's right, appearance comes from the heart. Comrade Li is an extraordinary person at first glance."

Li Yuan also had to admit that these managers were indeed far superior to others in dealing with people.

I know clearly that they are telling lies, but they just sound comfortable.

"I don't know, you two?"

Li Yuan took the initiative to admit defeat, and he couldn't stand the praise from the two people.

The two were not as reckless as Liu Gong and Lei Gong, and visited friends in Kyoto throughout the period.

From their mouths, we learned that chip technology is the most advanced technology in the world today and the pearl among industrial pearls.

There is currently no similar technology in China.

This discovery surprised them.

According to reports from LiuGong and LeiGong, the last experiment used a special chip.

And as far as they know, there is a chip production base in the mountainous area of ​​Mianyang.

Some military research institutions have obtained guidance documents for chip design.

The two are connected, and they have to take Li Yuan seriously.
