Chapter 1825 The motivation is not enough
“Old Chen, go and take a rest!”
Taking advantage of his free time, Yang Xiaotao looked at Chen Chonghan still busy and said, “I’m here. That’s fine, just sit aside for a while.”
Chen Chonghan shook his head after hearing this, "It's okay. I'll take it slow and my body will just get used to it."
"By the way, the compressor is ready this time. Next, you can move on to the engine combustion chamber. What are you going to do?”
While Chen Chonghan was making parts, he asked about the engine.
"This combustion chamber is a big problem. We spent a lot of effort in Shicheng before we could barely meet the acceptance requirements."
"Especially the material problem, each All kinds of alloy metals have been tried, how can we make The sample scraps that came in were piled up in half the room.”
Now, Yang Xiaotao’s Hongxing Machinery Factory’s ‘HXJ-1’ project has been in progress for more than four months. Said the progress was pretty smooth.
So far, the production of the air intake device blades has been completed, as well as the production of the first difficult press.
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 is installed in the front inner box, and there are also adjustable inlet guide vanes. This design is refreshing to him, at least three machines According to the news from the Ministry, the front air intake device is the same as the previous MiG engine.
And the compressor, this is one of the main projects he studied at the Shicheng Research Institute.
Compared with the structural blueprint of the compressor that I got at that time, it was almost a younger brother than the one designed by Yang Xiaotao.
This 14-stage axial flow type has six more stages than the opponent's.
Especially the five at the back are adjustable blades. He really dared to think of this design.
Don’t he know the consequences of lax design?
Doesn’t he know that this kind of design that requires judgment can easily fail when it is made?
There is also this difficulty. He himself is an eighth-level master, doesn’t he understand?
But Yang Xiaotao did just that.
However, a group of guys in the machinery factory who were pumped up just followed this trick, as if they didn't miss the drawings that Yang Xiaotao took out.
If it hadn’t been made possible through everyone’s hard work, he would have doubted whether Yang Xiaotao would dare to design anything as he thought.
Fortunately, everyone has mastered the manufacturing method. I don’t say it is 100% successful, but there is a half success rate.
If training is strengthened in the future, or the accuracy of the machine tool is improved, the success rate will increase.
The next combustion pressurized chamber is another key part of the engine.
When Chen Chonghan said this, he also reminded Yang Xiaotao not to play tricks, just be normal.
Getting to this point is not easy, just do it step by step.
However, after Chen Chonghan said so much, Yang Xiaotao still calmly picked up the new rough embryo and placed it on the machine tool. Then he turned back and looked at Chen Chonghan in surprise, "Combustion chamber? Oh, you said that. It’s for the engine.”
“Well, I’m not going to make the combustion chamber?”
Chi~~~
Chen Chonghan flicked his finger, and a piece of the entire component was chipped off, turning it into a scrap.
Several operators around heard the sound and immediately looked over. Seeing that Chen Chonghan had made the wrong parts, they were curious, knowing that he had never made mistakes before.
But at this time, Chen Chonghan couldn't care less. He put down the machine tool, turned off the power, and walked to Yang Xiaotao, "You, what did you just say?"
"I don't plan to make a combustion chamber. ?”
“No, what are you talking about? If you don’t make a combustion chamber, what kind of engine are you going to make?”
"Doesn't your engine have a combustion chamber?"
"No, it's impossible, how could it not be possible?"
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 Three Machinery Department.
“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 make a turbine first."
Yang Xiaotao said his thoughts, and Chen Chonghan stood on the spot with a solemn expression.
“Make the turbine first? I remember that for the engine of the Third Engine Department, the combustion chamber was made first, and then the turbine was made.”
"Did you make the tail nozzle after the turbine?"
Yang Xiaotao asked casually while fixing the rough blank and getting ready to dry it.
Seeing Chen Chonghan standing aside and nodding, he had better explain clearly first.
"Yes, we did it according to the axial flow line, step by step, and finally made it."
"So, that is your engine, not what I want to do .”
Yang Xiaotao spoke calmly.
Chen Chonghan was speechless.
As a seventh-level engineer recognized by the system, Yang Xiaotao has acquired knowledge that people like Chen Chonghan cannot imagine, and they have never been exposed to.
Yang Xiaotao realized this problem when he was sorting out the AL-21 engine drawings.
If you follow the steps step by step, you should be able to do it from beginning to end.
But things are urgent, so respond accordingly.
From the time when the blades were first manufactured, Yang Xiaotao discovered that some things cannot be dogmatic, 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 after the fuel is ignited, the high-temperature and high-pressure gas in the combustion chamber is intended 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 shoe should fit the size of the foot, not the tightness of the shoe, not the foot.
Of course the latter can be worn, but it doesn’t fit your feet.
"My idea is to make the turbine first, and then the combustion chamber."
"The core part is done, and the rest is easy to talk about."
Yang Xiaotao did not explain , just speaking his mind.
Chen Chonghan came to his senses and realized that Yang Xiaotao had the final say in this matter, so he could only provide some reference advice.
The thought of what happened to this combustion chamber when he was manufacturing engines in Shicheng gave him a headache.
When other research institutes sent over the completed turbines, my dear, when I looked at the data sheet, it was much different from the original designer’s data.
Later I 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.
This time, their combustion chamber will naturally change.
But this thing cannot be changed by simply changing it.
Especially the issues of thermal and aerodynamic forces. In the experiment, they were completely covered by the designer's various 'data'.
However, he has not seen all of Yang Xiaotao's engine drawings, and it is not even clear whether Yang Xiaotao designed them all. But judging from his experience, this kind of design that is just done without verification is prone to problems.
Maybe Yang Xiaotao has strong energy and he has already proved it, 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 found no suitable one. Then it was delayed for another three months. After no suitable material was found, the superiors could only modify the design. drawing.
Increase the thickness of the combustion chamber to ensure the success of the experiment.
Finally, it can be considered a successful acceptance.
All of this is experience.
And he felt it was necessary to tell Yang Xiaotao.
"Mr. 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 rotates, the front It's still taking in air, still compressing, and the gas is constantly coming in, burning, and being discharged."
Chen Chonghan gestured to Yang Xiaotao on the spot, with a serious look on his face.
It can be seen that this guy has worked hard and learned a lot in order to help the Third Machinery Department manufacture engine parts.
“There is no problem if you want to make the turbine first, but if the data is wrong, you can’t change it even if you change it.”
"It can only be redesigned."
Chen Chonghan carefully reminded Yang Xiaotao, fulfilling the responsibility of a worker.
"Besides, this combustion chamber is not something ordinary materials can withstand."
Yang Xiaotao didn't mind Chen Chonghan's temperament. On the contrary, if the other party could tell him so much, then Believe in him.
That’s because I really want to make a good engine.
Besides, Yang Xiaotao is not someone who cannot listen to opinions, let alone someone who cannot tolerate objections.
It’s just that sometimes, he has his own reasons for his persistence, but it’s just not convenient to say them out.
This makes it easy for people to misunderstand, thinking that Yang Xiaotao is a bit arrogant and has no choice but to agree with him.
After Chen Chonghan finished speaking, Yang Xiaotao nodded, "Don't worry, I have taken these into consideration."
"As for the design requirements, no one is allowed to change them without authorization. Nothing can be discussed.”
"As for the issue of materials, I am confident that even if there is no material, we can make a new material."
"Otherwise, what is the use of supporting so many people in United Star?"
Chen Chonghan shook his head helplessly after hearing this. Yang Xiaotao was so confident that no one could refute him.
"Okay, let's do it step by step. It's only July now. Just make it before October 1st."
Chen Chonghan rolled his eyes after hearing this. You can't do it before October 1st. It only took less than half a year. The engine we made for the Third Machinery Department took a full two and a half years.
This guy really dares to say anything.
"Okay, if you get tired, go sit and have a rest."
"I'll be busy first."
After saying that, Yang Xiaotao turned back and continued processing parts. Chen Chonghan looked at it and walked towards the machine tool.
Isn’t it just a threshing machine? This thing is far inferior to an aircraft engine.
Who are you looking down on?
Three Machinery Department.
Mr. Zhang was sitting in the office, beads of sweat appeared on his forehead from time to time, then he wiped it with a towel, and then continued to look through the documents.
Click
Throwing the document aside, Zhang Lao stood up and walked to the window, feeling the temperature outside the window. There was no cool breeze, which made him feel even more irritable.
He turned around and picked up the documents on the table again, looked at them twice, then opened the door and walked out.
In the director’s office.
Director Zheng Zheng Shuangyan is holding the phone, her face is anxious, and her voice is full of urgency.
"Lao Ran, please help me ask if your Qian Lao has any ideas."
"Hey, Comrade Ran Zhiqiang, is this how you treat your revolutionary brothers?"< br>
"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 if he said he would not help, he must have heard it in his heart.
As for whether it can be done, it depends on Mr. Qian’s attitude.
Lao Ran will definitely say it.
Just when Director Zheng was thinking about Lao Ran, 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'm just here to take a look."
Mr. Zhang said, but Director Zheng knew better.
The person in front of me has always been a man who sits in the office, is unfazed by favors and humiliations, and never comes out easily.
Now that he has come out, it means that this person really cannot sit still.
And he naturally knows the reason for all this.
Mr. Zhang didn't even sit down, so he stood aside and asked, "Have you read the report from Shen Fei?"
"Bluebird didn't meet the requirements."
"Look Yes, the motivation is still low."
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 generated airflow and exhaust airflow did not meet the power requirements."
" Is there any solution?"
Director Zheng shook his head, "Still looking."
Mr. Zhang took a deep breath, "Hurry up."
"Before the Mid-Autumn Festival. , must be solved.”
Director Zheng nodded, "Don't worry, I will definitely find a way to solve the problem."
Mr. Zhang nodded, then turned and left.
After waiting for others to leave, Director Zheng went to his desk again, thought for a while and picked up the phone, "Hello, Mr. Wang, I'm Lao Zheng."
