Scholars in the courtyard

"Old Chen, take a break!"

Taking advantage of his free time, Yang Xiaotao saw Chen Chonghan still busy and said, "I'll be here, sit over there for a while."

Chen Chonghan shook his head and said, "It's okay, I'll take my time, my body is just right for adaptation."

"By the way, the compressor is already done this time, what are you going to do with the next engine combustion chamber?"

Chen Chonghan asked about the engine while making parts.

"This combustion chamber is a big problem. Back in Shicheng, we took a lot of effort to barely meet the acceptance requirements."

"Especially the material problem. We tried all kinds of alloy metals, and the waste samples filled up half of the room."

Now, the Red Star Machinery Factory's 'HXJ-1' plan proposed by Yang Xiaotao started in March and has been in operation for more than four months. Overall, the progress is relatively smooth.

So far, the production of the intake blades and the first difficult press have been completed.

However, some of the designs also made him feel novel.

Just like the air intake device, according to Yang Xiaotao's design, a front bearing was installed in the front inner box, and an adjustable inlet guide vane was also installed. This design was refreshing to him. At least the news from the Third Machine Department was that the front air intake device was the same as the previous MiG engine.

And the compressor, this is one of the main projects he studied at the Shicheng Institute.

The compressor structure drawings he got at that time were simply a little younger than the one designed by Yang Xiaotao.

This 14-stage axial flow type has six more than the opponent's.

Especially the five adjustable blades at the back, this design is really daring.

Doesn't he know what consequences will be caused by the lack of rigor in the design?

Doesn't he know that this kind of design that requires judgment is easy to fail?

And this difficulty, he is an eighth-level master, doesn't he understand?

But Yang Xiaotao did it.

It just so happened that a group of guys in the machinery factory who were pumped up with chicken blood fell for this, as if the drawings Yang Xiaotao took out were not wrong.

If it wasn't finally made with everyone's efforts, he would have suspected that Yang Xiaotao was just thinking about it and dared to design anything.

Fortunately, everyone has mastered the manufacturing method. It can't be said to be 100% successful, but there is a 50% success rate.

If we strengthen our training in the future or the accuracy of the machine tool is improved, the success rate will increase.

And the next combustion and compression chamber is another key part of the engine.

Chen Chonghan said this to remind Yang Xiaotao not to do those weird things, just be normal.

It's not easy to get to this point, just follow the steps.

However, after Chen Chonghan said so much, Yang Xiaotao still calmly picked up the new rough blank and put it on the machine tool, and then turned back to look at Chen Chonghan in surprise, "Combustion chamber? Oh, you mean the engine."

"Well, this, I don't plan to make a combustion chamber?"

Shh~~~

Chen Chonghan's fingers trembled, and a piece of the entire component was cut off, and it became a waste directly.

Several operators around heard the sound and looked over immediately. Seeing that Chen Chonghan had made a mistake, they were curious. You know, he had never made a mistake before.

But at this time, Chen Chonghan didn't care. He put down the machine tool, turned off the power, and walked to Yang Xiaotao, "You, what did you say just now?"

"You don't plan to make a combustion chamber?"

"No, what did you say, if you don't make a combustion chamber, what kind of engine are you making?"

"Don't your engine have a combustion chamber?"

"No, it's impossible, how can it not have one?"

Chen Chonghan's eyes were full of doubt and a little excitement.

The engine designed by this guy is indeed different from the Third Machine Department.

"I didn't say there is no combustion chamber."

Seeing Chen Chonghan coming over excitedly, Yang Xiaotao spoke slowly.

"Then you are"

"I want to make a turbine first."

Yang Xiaotao expressed his thoughts, and Chen Chonghan stood there with a solemn expression.

"Make the turbine first? I remember that the engines of the Third Machine Department made the combustion chamber first, and then the turbine."

"Is it the tail nozzle that was made after the turbine?"

Yang Xiaotao fixed the rough blank on the side and prepared to start working, and asked casually.

Seeing Chen Chonghan standing aside and nodding, he had better explain it clearly first.

"Yes, we made it according to the axial streamline, step by step, and finally made it."

"So, that's your engine, not what I want to make."

Yang Xiaotao said lightly.

Chen Chonghan was speechless.

As a system-recognized seventh-level engineer, Yang Xiaotao has acquired knowledge that Chen Chonghan and others can't imagine, and they have never touched it.

Yang Xiaotao realized this problem when he was sorting out the AL-21 engine drawings.

If you follow the steps, you should be able to make it from beginning to end.

But things have their urgency, and you should respond accordingly.

From the initial blade manufacturing, Yang Xiaotao found that some things can't be dogmatic, just like a press. Since it can't be done in one step, why not disassemble it for processing.

Isn't the problem solved now?

So after studying the diagram, Yang Xiaotao found that the purpose of the high-temperature and high-pressure gas in the combustion chamber after the fuel is ignited is to drive the turbine. Since the purpose is the turbine, why not make the turbine first?

This is the relationship between shoes and feet.

The shoes should be suitable for the size of the feet, not the feet to adapt to the tightness of the shoes.

The latter is certainly wearable, but it doesn't follow the foot.

"My idea is to make the turbine first, and then the combustion chamber."

"Once the core part is made, the rest will be easy."

Yang Xiaotao did not explain, but just expressed his thoughts.

Chen Chonghan came back to his senses and knew that Yang Xiaotao had the final say in this matter, and he could only give a reference opinion at most.

But thinking of the experience of this combustion chamber when manufacturing the engine in Shicheng, he couldn't help but have a headache.

When other research institutes sent the finished turbines, my goodness, when I looked at the data sheet, it was much different from the data of the original designer.

Later, they asked that it was a design problem, and the corresponding data could not be achieved according to the design requirements.

So their research institute contacted the designer and adjusted the data.

Now, their combustion chamber will naturally change.

But this thing can't be changed just by saying it.

Especially the problems of thermal and aerodynamic forces, in the experiment, they were completely beaten to pieces by the designer's various "data".

However, he has not seen all of Yang Xiaotao's engine drawings, and he doesn't even know whether Yang Xiaotao has designed them all.

But from his experience, this kind of design that is done right away without verification is prone to problems.

Perhaps Yang Xiaotao has strong energy and has verified it himself, but there are always various problems and difficulties in production.

When he was working in Shicheng, because the material of the combustion chamber was not up to standard, he finally searched all over the country and couldn't find a suitable one. Then it was delayed for another three months. After not finding a suitable material, the superiors could only modify the design drawings.

The thickness of the combustion chamber was increased to ensure the success of the experiment.

In the end, it was successfully accepted.

All of this is experience.

And he felt it necessary to tell Yang Xiaotao.

"Mr. Yang, this combustion chamber has to withstand the high-pressure gas of the compressor, and then the oil goes in and burns. This process is a high-temperature and high-pressure state, and it is dynamic. That is to say, when the turbine is rotating, the front is still taking in air and compressing, and the gas is constantly coming in, burning, and discharging."

Chen Chonghan gestured to Yang Xiaotao on the spot with a serious expression.

It can be seen that in order to help the Third Machine Department manufacture engine components, this guy also worked hard and learned a lot.

"It's fine if you want to make the turbine first, but if the data is wrong, there's nothing you can do about it."

"You can only redesign it."

Chen Chonghan carefully reminded Yang Xiaotao, fulfilling his responsibility as a worker.

"In addition, this combustion chamber is not something that ordinary materials can withstand."

Yang Xiaotao didn't mind Chen Chonghan's temper. On the contrary, the other party could tell him so much, which means he believed in him.

That's because he really wanted to make a good engine.

Besides, Yang Xiaotao is not someone who doesn't listen to opinions, let alone someone who can't stand opposition.

It's just that sometimes, he has his own reasons for insisting, but it's just not convenient to say it out.

This makes it easy for people to misunderstand that Yang Xiaotao is a little arrogant and can't tolerate different opinions.

After Chen Chonghan finished speaking, Yang Xiaotao nodded, "Don't worry, I have taken all these into consideration."

"Regarding the design requirements, no one is allowed to make changes without authorization. This is non-negotiable."

"As for the material issue, I am confident that even if there is no material, we can make a new material."

"Otherwise, why do we need to support so many people in United Star."

Chen Chonghan shook his head helplessly. Yang Xiaotao's confidence always made people unable to refute.

"Okay, let's do it step by step. It's only July now. We just need to make it before October 1st."

Chen Chonghan rolled his eyes after hearing this. It's less than half a year before October 1st. The engine we made for the Third Machine Department took a full two and a half years.

This guy, really, dares to say anything.

"Okay, if you are tired, go sit aside and rest."

"I'm busy first."

After speaking, Yang Xiaotao turned back to continue processing parts. Chen Chonghan looked at him and walked to the machine tool.

It's just a thresher. Compared to an airplane engine, this thing is far inferior.

Who are you looking down on?

The Third Machine Ministry.

Old Zhang sat in the office, sweat beads appeared on his forehead from time to time, and then he wiped it with a towel and continued to look through the documents.

Click

Throwing the documents aside, Old Zhang stood up and walked to the window, feeling the temperature outside the window. There was no cool breeze, which made him even more irritated.

He turned around and picked up the documents on the table again, took a look at them, and then pushed the door open and walked out.

In the director's office.

Director Zheng Shuangyan was holding the phone, looking anxious, and speaking in an anxious voice.

"Old Ran, please help me find out if your old Qian has any ideas."

"Hey, Comrade Ran Zhiqiang, is this how you treat your revolutionary brothers?"

"Old Ran, please help me~~~"

"Hello~~~"

Director Zheng took a deep breath and hung up the phone helplessly.

But a smile of conspiracy appeared on his face.

Based on his understanding of Lao Ran, even though he said he would not help, he must have taken it to heart.

As for whether it can be done, it depends on Mr. Qian's attitude.

Lao Ran will definitely say it.

Just as Director Zheng was thinking about Lao Ran's matter, the door of the office was pushed open, and then he saw Mr. Zhang walking in with his hands behind his back.

Director Zheng immediately stood up from his seat.

"Chief!"

"Old Zheng, sit down. I just came to take a look."

Mr. Zhang said, but Director Zheng knew.

The man in front of him always stayed in the office, not surprised by praise or criticism, and never came out easily.

Now that he came out, it means that he really couldn't sit still.

And he naturally knew the reason for all this.

Mr. Zhang didn't sit down either, but stood aside and asked, "Have you read the report from Shen Fei?"

"Bluebird didn't meet the requirements."

"I saw it, and the power is still a little short."

Director Zheng answered seriously, and Mr. Zhang nodded.

"What's the reason?"

Director Zheng shook his head, "I don't know the details, but the engineers below think that it's because the compressor and combustion chamber did not meet the design standards, and the airflow generated and the exhaust airflow did not meet the power requirements."

"Is there any way to solve it?"

Director Zheng shook his head, "I'm still looking for it."

Mr. Zhang took a deep breath, "Hurry up."

"It must be solved before the Mid-Autumn Festival."

Director Zheng nodded, "Don't worry, I will definitely find a way to solve the problem."

Mr. Zhang nodded, then turned and left.

After everyone left, Director Zheng sat down at his desk again, thought for a moment, and picked up the phone. "Hello, Mr. Wang, this is Mr. Zheng."
