Chapter 1825: Motivation is still lacking

"Old Chen, go take a break!"

Taking advantage of the free time, Yang Xiaotao saw Chen Chonghan still busying himself and said, "I'll be here, you can sit over there for a while."

Chen Chonghan shook his head after hearing this and said, "It's okay, I'll take it slow so my body can get used to it."

"By the way, the compressor is now ready. What are you going to do with the engine combustion chamber?"

While Chen Chonghan was working on the parts, he asked about the engine.

"This combustion chamber is a big problem. Back in Shicheng, we had to work very hard to barely meet the acceptance requirements."

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

Now, the 'HXJ-1' project of the Red Star Machinery Factory proposed by Yang Xiaotao started in March and has been going on for more than four months. Overall, the progress is smooth.

To date, the production of intake blades has been completed, as well as the production of the first difficult press.

However, some of the designs also seemed novel to him.

Just like the air intake device, according to Yang Xiaotao's design, a front bearing was installed inside the front inner box. In addition, it was also equipped with adjustable inlet guide vanes. This design was refreshing to him. At least according to the news from the Third Ministry of Machine Building, the front air intake device was the same as the previous MiG engine.

And there is the compressor, which is one of the main projects he is researching at the Stone City Institute.

The compressor structure drawings we got at that time were far inferior to those designed by Yang Xiaotao.

This 14-level axial flow type has six more than the opponent.

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

Doesn't he know what consequences will result from carelessness in design?

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

There is still such difficulty. He himself is an eighth-level master chef. Doesn’t he understand?

But Yang Xiaotao did just that.

But the group of excited guys in the machinery factory just fell for it, as if there was nothing wrong with the drawings Yang Xiaotao took out.

If it wasn't finally made with the efforts of everyone, he would have suspected that Yang Xiaotao was just doing whatever he wanted and daring to design anything.

Fortunately, everyone has mastered the manufacturing method. I can’t say it’s 100% successful, but there is a 50% success rate.

If we strengthen our training in the future or improve the accuracy of machine tools, the success rate will increase.

The next combustion pressure chamber is another key part of the engine.

Chen Chonghan said this to remind Yang Xiaotao not to do anything weird and just be normal.

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

However, even though Chen Chonghan said so much, Yang Xiaotao still calmly picked up the new rough blank and placed it on the machine tool. Then he turned around and looked at Chen Chonghan in surprise, "Combustion chamber? Oh, you mean the engine one."

"Well, this, I'm not going to make a combustion chamber?"

scoff~~~
Chen Chonghan's fingers trembled, and a piece of the entire component was chipped off, turning it into waste.

Several operators nearby heard the sound and looked over immediately. Seeing that Chen Chonghan had made a mistake in the part, they were all curious, because he had never made a mistake before.

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

"Not planning on making a combustion chamber?"

"No, what are you talking about? If you don't make a combustion chamber, what kind of engine are you making?"

"Does your engine have no combustion chamber?"

"No, it's impossible. How can there not be?"

Chen Chonghan's eyes were filled with surprise and a hint of excitement.

The engine designed by this guy is indeed different from that of the Third Ministry of Machine Building.

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

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

"Then you are"

“I want to do the turbine first.”

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

"Make the turbine first? I remember that the Third Machine Department's engine 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 workpiece on the side and prepared to start working, and asked casually.

Seeing Chen Chonghan standing aside and nodding, he decided to explain it clearly first.

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

"So, that's your engine, not what I do."

Yang Xiaotao spoke lightly.

Chen Chonghan was speechless.

As a level 7 engineer recognized by the system, the knowledge Yang Xiaotao acquired was unimaginable to people like Chen Chonghan, and was something they had never come into contact with.

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 do it from front to back.

However, there are urgency and we must act according to our discretion.

From the very beginning of blade manufacturing, Yang Xiaotao discovered that some things cannot be rigidly followed, just like a press. Since it cannot be done in one step, why not disassemble it and process it.

Isn’t the problem solved now?
So after studying the diagram, Yang Xiaotao discovered that the purpose of the high-temperature and high-pressure gas in the combustion chamber is to drive the turbine after the fuel is ignited. Since the purpose is the turbine, why not make a turbine first?
This is the relationship between shoes and feet.

The shoes should fit the size of your feet, not the feet.

The latter is wearable, but it doesn't fit my feet.

“My idea is to make the turbine first and then the combustion chamber.”

"Now that the core part is done, everything else will be easy."

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

Chen Chonghan came to his senses and realized that Yang Xiaotao had the final say in this matter and he could only offer some reference opinions at most.

But when he thought about what happened to this combustion chamber when the engine was manufactured in Shicheng, he couldn't help but feel a headache.

When other research institutes sent their finished turbines to us, we were shocked to see that the data sheets were quite different from those of the original designers.

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

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

At this point, their combustion chamber will naturally change.

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

Especially the problems of thermal and aerodynamics, they were completely beaten to pieces by the various "data" provided by the designers during the experiments.

Although he had not seen all of Yang Xiaotao's engine drawings, and was not even sure whether Yang Xiaotao had designed them all, based on his experience, such a design that was done right away without any verification was likely to go wrong.

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

When he was working in Shicheng, the materials for the combustion chamber did not meet the standards. In the end, he searched the entire country but could not find any suitable ones. Then the project was delayed for another three months. After failing to find suitable materials, he had no choice but to modify the design drawings.

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

Finally, it was successfully accepted.

All of this is experience.

And he felt it necessary to tell Yang Xiaotao about it.

"Boss Yang, this combustion chamber has to withstand the high-pressure gas from 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 it. The gas is constantly coming in, burning, and being discharged."

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

It can be seen that in order to help the Third Ministry of Machine Building to manufacture engine components, this guy 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."

“It can only be redesigned.”

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

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

Yang Xiaotao didn't mind Chen Chonghan's personality. On the contrary, the fact that he could tell him so much showed that he trusted him.

That's because I really want to make a good engine.

Besides, Yang Xiaotao is not someone who won't listen to opinions, nor is he someone who can't stand opposition.

It’s just that sometimes, he has his own reasons for insisting, but he just doesn’t feel comfortable saying it out loud.

This can easily lead people to misunderstand that Yang Xiaotao is a little arrogant and intolerant of different opinions.

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

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

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

"Otherwise, what's the point of supporting so many people in United Star?"

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

"Okay, let's take it step by step. It's only July now, so we just need to finish it before October 1st."

Chen Chonghan rolled his eyes when he heard this and said, "It was less than half a year before October 1st, but the engine we made for the Third Ministry of Machine Building took us a full two and a half years."

This guy, really, dares to say anything.

"Okay, if you're tired, just go sit aside and take a rest."

"I'm busy now."

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

It's just a thresher. It's far inferior to an airplane engine.

Who are you looking down on?

The Third Ministry of Machine Building.

Mr. Zhang sat in the office, beads of sweat appearing on his forehead from time to time. He wiped it with a towel and continued to look through the documents.

patter
Throwing the document aside, Mr. Zhang stood up and walked to the window, feeling the temperature outside. There was not a trace of cool breeze, which made him even more irritated.

He turned around and picked up the document on the table again, looked at it for a few seconds, then pushed open the door and walked out.

In the director's office.

Director Zheng Shuangyan was holding the phone, her face anxious and her voice eager.

"Lao Ran, can you help me find out if your old Qian has any idea?"

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

"Lao Ran, please help me, brother~~~"

"Hello~~~"

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

But there was a smile of success on his face.

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

As to whether it can be done, that depends on Mr. Qian’s attitude.

Lao Ran will definitely tell it.

Just as Director Zheng was thinking about Old Ran's matter, the office door was pushed open, and then he saw Old 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 over to take a look."

Mr. Zhang started talking, but Director Zheng knew clearly.

The person in front of me always sits in the office, unperturbed by fame or disgrace, and rarely comes out.

Now that he has come out, it means that this person really can't sit still anymore.

He naturally knew the reason for all this.

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

"Bluebird didn't meet the requirements."

"Look, the motivation is still lacking."

Director Zheng answered seriously and Mr. Zhang nodded.

"what is the reason?"

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

“Is there any solution?”

Director Zheng shook his head, "Still looking."

Zhang Lao took a deep breath and said, "Hurry up."

"It must be resolved 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."
