Scholars in the courtyard.

Chapter 2025: Compare the goods and throw them away!

"It can't be wrong."

At this time, Mr. Zhang suddenly spoke.

"I've learned about the process of manufacturing aircraft engines at the machinery factory. For production purposes, they specifically researched titanium alloys."

"Also, the design coefficients are strictly enforced and changes to the design drawings are not allowed."

"With this attitude and these three years of hard work, do you think this is just training?"

Mr. Zhang spoke calmly, with a hint of anticipation in his heart.

Looking forward to what the engine made by the machinery factory will look like.

Compare it with their engines using new materials and see which one is better.

Liu Huaimin opened his mouth but could not utter a word.

After all, this incident happened in a machinery factory, but he, as the secretary, was completely unaware of it. It can be said that he was derelict in his duty.

Of course, dereliction of duty is another matter.

If Yang Xiaotao can make this aircraft engine successfully, then...
Wouldn't that mean the Red Star Machinery Factory has another way to make money?
And with Yang Xiaotao's design talent, the engine he designs will definitely not be bad.

Even if it is not as good as the engine of the Logistics Department of the Third Ministry of Machine Building, it should not be much worse.

What’s more, something went wrong in the logistics department.

Therefore, as long as Yang Xiaotao's engine can operate normally, he can compete with the Third Ministry of Machine Building.

Even before the results came out, Liu Huaimin was already full of confidence in Yang Xiaotao.

"No wonder, no wonder this guy keeps making pills."

"It turns out that you have already thought about the backup plan."

"This bastard."

Liu Huaimin muttered to himself with a smile on his face.

Unfortunately, although the sound was not loud, several people present could hear it roughly.

Especially Old Qin, his expression became even uglier.

"What did you say? What's the big deal?"

Old Qin asked unhappily, "What pills? What guarantee? Explain clearly."

Liu Huaimin couldn't say anything after hearing this, and hurriedly explained, "I mean, no wonder this guy wants to make aircraft engines, it turns out he has been prepared for it, he has been prepared for it."

Then he looked at Mr. Chen, the boss of the machinery factory, and said, "Commander, I don't know much about this matter. How about we wait for Comrade Yang Xiaotao to come back?"

Elder Chen looked at the two of them, then nodded, "Okay, call him and ask him to come back."

Liu Huaimin nodded, immediately picked up the phone on the table and called the chemical plant.

Mr. Chen stood up and said, "Since we are here, let's go to the workshop and take a look."

Old Qin stood up, and Old Zhang followed behind him.

The purpose of their visit this time was, first, to learn about the machinery factory's research on aircraft engines, and second, to see whether the finished products were better than theirs.

This is very important.

After Liu Huaimin finished the call, he hurried to a workshop.

At this moment, in a workshop, Zhang Guanyu was directing everyone to start manufacturing the afterburner.

The front combustion chamber was a bit more difficult, but it was made out of TiG01 alloy, so everyone thought the afterburner would be easy to complete.

But unexpectedly, everyone made a mistake here.

Although Yang Xiaotao said that there would be more suitable alloy materials, they are not available now, so I can only use this to practice.

Anyway, the requirements in this design drawing can be met.

However, it is a bit difficult to make this afterburner now.

Because according to the design drawings provided by Mr. Yang, the afterburner of this aircraft is a highly complex and critical component.

It will consist of a diffuser, a flame stabilizer, an oil transfer ring and fuel nozzle, an ignition device, an afterburner shell and other parts.

Its main task is to generate higher thrust under conditions of high temperature and high pressure.

In other words, it goes without saying that the materials needed are not much, and there cannot be any problems in the manufacturing process.

According to the design requirements, they began trial manufacturing.

I tried it several times but failed.

The biggest problem here is the ability of the combustion chamber shell to withstand high temperature and high pressure.

The TiG01 alloy originally used to make the combustion chamber did not achieve the desired results in several experiments.

The most critical part is the welding of the shell.

Originally, according to the idea of ​​several people, the outer shell was made directly with a punch press, so there would be no welding problem.

However, Zhou Hong, the best lathe master in the machinery factory, tried it himself but failed several times.

The reason is simple, that is, the structure is too complicated. If you are not careful, it will cause lack of precision, thus affecting the production of other parts.

After trying several times without success, everyone had to put their hopes on welding.

Looking at Shi Hanzi who was lighting the welding rod, Zhang Guanyu's palms were sweating.

This is the third time.

I tried it twice before, but failed.

This put a lot of pressure on Shi Gan, the eighth-level welder in charge of welding.

But in order to succeed, he had to pick up the welding gun for the third time.

This time, he would use better dragon scale welding to complete the task.

Just when everyone was concentrating and didn't dare to get too close, Zhang Guanyu suddenly felt someone patting his shoulder.

There was also a sound in my ear.

"Director Zhang!"

Zhang Guanyu immediately turned around and put his finger on his mouth, "Shhhhh, don't say anything."

"Um, Secretary. And, and the Chief."

After Zhang Guanyu said this, the people around him immediately looked over and found Chen Lao and his two companions, followed by many guards from the machinery factory.

"What are you doing?"

Before Liu Huaimin opened his mouth, Mr. Chen started asking.

Zhang Guanyu immediately said, "Commander, we are producing the casing of the engine's afterburner."

Old Chen nodded. Mainly because he didn't know much about it, he wanted to go in and take a look at the situation.

However, the eyes of Mr. Qin and others standing aside were stern.

Everyone quickly made way for it. When Chen and his companions came up, they saw bursts of dazzling light. A man sitting on the ground with bare arms and a welding mirror in his hand was working intently.

Even though several of them arrived, they did not attract the man's attention.

At this time, Director Zheng, who came with Mr. Zhang, was looking at the drawings beside him again and again.

The two people who came with Mr. Qin also came forward to observe the design drawings.

This is the design drawing of the afterburner, and several people confirmed it at a glance.

Then the three of them passed the drawings around one by one, and their faces became more and more solemn. They knew most of these designs, but they also found some of them very novel.

Moreover, from the perspective of the main structure, it is the same model as the design drawings provided by the alliance, but there are also some differences.

They also felt that the data requirements for this design were very high.

They are also familiar with the design principles of the afterburner and naturally understand the parameters of each component.

By comparison, the parameter requirements are more stringent than those of the engines designed by the two companies.

Seeing this, the two people from the logistics department have realized that what they saw last time was definitely not this one.

Perhaps, it was prepared for "peeping eyes" like them.

The two were in a bad mood, and then they walked up to Mr. Qin and told him about the situation.

At the same time, Mr. Zhang also heard Director Zheng's words and sighed in his heart.

Sure enough, nothing designed by Yang Xiaotao is simple.

Mr. Zhang, Mr. Qin and the other two did not say anything. They just looked at the welder who was busy in front of them and the people around them.

The requirements of the design drawing are one thing, and whether it can be made according to the requirements is another.

This is something they have experienced firsthand!

"Chief, this man should be using dragon scale welding."

"Dragon scale welding?"

The person who came with Old Qin looked for a while and suddenly started to introduce.

"Yes, this is a superb welding method! Of course, dragon scale welding is just a skill, and the difference lies in skill!"

"Some dragon scale welds are only slightly better than regular welds."

“But some welding is on another level entirely!”

After listening to this, Mr. Chen nodded. He had heard about this kind of thing.

"I remember this was at the last skill competition held at the machinery factory!"

Liu Huaimin quickly responded, "Yes, the commander has a good memory!"

"However, our comrade lost the competition and only came in second place!"

"The first place was..."

"Obtained by our comrades from the Third Machine Department!"

Mr. Zhang on the side suddenly spoke.

But there wasn't much joy on his face!

Liu Huaimin took a look and knew that there must be something going on, so he didn't say anything more.

But the person who came with Qin Lao continued to say,

“But the number of people who can master the advanced level can be counted on one hand.”

"The man in front of me is definitely an eighth-level master."

After the man finished speaking, he felt a little uneasy again, and then said, "In this way, they are likely to meet the data requirements above."

"Really?"

"Well, it should be true."

Qin Lao's heart tightened, and then he asked, "Can our people complete it?"

The man was silent for a moment, then shook his head.

"Although we have more than a dozen level eight welders, not everyone can master the dragon scale welding technique. They probably lack some skills."

After hearing this, Old Qin almost suffocated to death.

As a logistics department, it turns out that there are not as many talents as a machinery factory.

If you tell others about it, people will laugh at you.

Mr. Zhang and Mr. Chen, who were listening nearby, were also speechless.

Mr. Zhang was so happy because their Third Ministry of Machine Building had such a great master, who was even more capable than the person in front of him.

But, I can’t design such a good drawing!

Isn't it frustrating to have a master chef but not be able to do fine work?

As for Chen Lao Yu, he was speechless with joy.

The machinery factory really brought him honor.

But they soon turned their attention to the front.

"All right!"

Shi Hanzi put away the welding gun, disconnected the power supply, and then said to the people around him.

It was only at this time that he saw Mr. Chen and the others, and he immediately became reserved and a little at a loss.

Liu Huaimin glanced at everyone and said, "Do what you should do. The commander is just here to take a look!"

Hearing this, Zhang Guanyu exchanged glances with Liu Daming and others, then nodded and continued.

Liu Daming and Zhou Hong beside him immediately stepped forward to check, and some people even started checking with flashlights.

Zhang and his companions knew that they were checking the welding condition.

After a while, the initial inspection showed no problems.

This also confirmed everyone's guess that the middle-aged man in front of them was actually an eighth-level master chef.

"Send it for inspection!"

Liu Daming clapped his hands with anticipation on his face.

Someone immediately stepped forward, worked together to lift up the welded parts, and then put them aside to cool.

At this time, Chen Lao and his companions did not say much, they just walked forward and watched.

Director Zheng on the side handed over the design drawing.

This drawing is obviously drawn by someone with some skills.

So detailed!

Mr. Zhang and Mr. Qin brought their men to the outer shell and began to compare them with the design drawings.

At the same time, I also compare it with what I made at home.

You know what, there are actually some similarities between the two.

The overall appearance of this shell is almost the same!

Liu Huaimin called Zhang Guanyu to come forward and explain. Yang Xiaotao was not there, so Zhang Guanyu had to do it.

"You guys have achieved such high precision requirements?"

Pointing to the design requirements at the junction, Mr. Qin asked.

In his impression, the accuracy requirement of their engine at this position was reduced by half!
Zhang Guanyu took a look and then rubbed his nose. "Commander, this is where the pressurized chamber is placed. We tried three times before we finally found a way to make it. Now it meets the accuracy requirements."

Hearing this, Old Qin opened his mouth wide, not knowing what to say.

He even felt that the reason for the failure was the lack of an excellent manufacturing team.

If we pack these people up and take them back.
