Chapter 2025: Compare goods, have to throw them away!

“It can’t be wrong.”

At this time, Mr. Zhang suddenly spoke.

“I have learned about the aircraft engine manufacturing process in a machinery factory. In order to produce it, titanium alloy was specially studied.”

“Also, the design coefficient requirements are very strictly implemented. Strictly, no changes to the design drawings are allowed.”

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

Mr. Zhang said calmly, with some expectation in his heart.

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

Compare with their engines that use new materials to see who is better.

Liu Huaimin opened his mouth wide and was speechless.

After all, this happened in the machinery factory, but he, the secretary, didn't know anything about it, which was a dereliction of duty.

Of course, let’s talk about dereliction of duty.

If Yang Xiaotao makes this aircraft engine and succeeds, then...

Wouldn’t the Hongxing Machinery Factory have another way to make money?

And with Yang Xiaotao’s design talent, the designed engine will never be bad.

Even if it is not as good as the engine of the Logistics Department of the Third Machinery Department, it should not be much different.

Not to mention something happened in the logistics office.

So, as long as Yang Xiaotao's engine can run normally, he can compete with the Third Machinery Department.

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 I have already thought about the details."

"This bastard."

Liu Huaimin murmured to himself, with a smile on his face.

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

Especially Mr. Qin’s face became even more ugly.

"What are you talking about? No wonder?"

Mr. Qin asked displeasedly, "What pills, what details, tell me clearly."

Of course Liu Huaimin couldn't say anything after hearing this. He hurriedly explained, "I mean, no wonder this guy wants to build an airplane engine. It turns out that he has been prepared for it for a long time. Be prepared."

Then he looked at Mr. Chen, who was the boss of the machinery factory, "Chief, look, I don't know much about this either. Why don't you wait until Comrade Yang Xiaotao comes back?"
 Mr. Chen looked at the two of them, then nodded, "Okay, you call him and ask him to come back."

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

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

Mr. Qin stood up quickly, and Mr. Zhang followed behind.

They came here this time, firstly, to learn about the machinery factory’s research on aircraft engines, and secondly, to see if the finished product was better than what they made.

This is very important.

After Liu Huaimin made the call, he hurried to the first workshop.

At this moment, in a workshop, Zhang Guanyu was directing everyone to start making afterburners.

The front combustion chamber is a bit difficult, but it is still made of TiG01 alloy, so everyone thinks that the afterburner will be easy to complete.

But unexpectedly, everyone made a mistake here.

Although Yang Xiaotao said that there will be more suitable alloy materials to make it, but there is none now, I can only use this to practice.

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

It’s just that it’s a little more difficult to make this afterburner now.

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

It will be composed of a diffuser, a flame stabilizer, a fuel delivery ring and a fuel nozzle, an ignition device, and an afterburner housing.

Its main task is to generate higher driving force under high temperature and high pressure conditions.

In other words, there is no need to say much about the materials required, nor should any problems just arise during the manufacturing process.

According to the design requirements, they began trial manufacturing.

I just tried it several times without success.

The biggest problem 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 failed to 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 shell was made directly with a punch, so that there was no problem of welding.

But Zhou Hong, the best lathe master in the machinery factory, tried it himself and tried it several times without success.

The reason is very simple, that is, the structure is too complex. If you are not careful, it will cause a loss of precision, which will affect the production of other parts.

After trying several times, it didn’t work, so everyone had to pin their hopes on welding.

Seeing Shi Hanzi's face lighting up the welding rod, Zhang Guanyu's hands became sweaty.

This is the third time.

I did it twice before, but without success.

This puts Shi Gan, the eighth-level welder responsible for welding, under a lot of pressure.

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

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

Just when everyone was concentrating and did not dare to get too close, Zhang Guanyu suddenly felt someone tapping his shoulder.

There was still a sound in my ears.

"Director Zhang!"

Zhang Guanyu immediately turned around and put his finger on his mouth, "Shhhhhh, don't say it"

"Uh, secretary. And also the chief."

When Zhang Guanyu said this, the people around him immediately looked over, and then they discovered the three of them, Mr. Chen, followed by many guards from the machinery factory.

"What are you doing?"

Before Liu Huaimin opened his mouth, Mr. Chen asked.

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

Mr. Chen nodded, mainly because he didn't know much about it, but wanted to go in and see the situation.

On the other hand, Mr. Qin and the others looked at him with stern eyes.

Everyone quickly moved out of the way. When Mr. Chen and others came forward, they saw bursts of dazzling light. The man sitting on the ground had his bare arms and a welding mirror in his hand. Concentrate on your work.

Even if a few of them arrived, they did not attract the man's attention.

At this time, Director Zheng, who had followed Mr. Zhang, was looking at the drawings on the side.

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

This is the design drawing of the afterburner, which several people can confirm at a glance.

The drawings were then circulated among the three of them, and their expressions became more and more solemn. Most of these design drawings were familiar to them, but there were some parts that they found very novel.

Furthermore, from the main structure point of view, it is the same model as the design diagram provided by the alliance, but it is also somewhat different.

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

They also all know the design principles of the afterburner, and naturally understand the parameters of each component.

For comparison, the requirements for these parameters are stricter than those of the engines designed by the two of them.

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

Perhaps, it is prepared for 'peepers' like them.

The two of them were in a bad mood, and then walked to Mr. Qin and explained the situation.

At the same time, Mr. Zhang also sighed in his heart when he heard what Director Zheng said.

Sure enough, none of the things Yang Xiaotao designed was simple.

Both Mr. Zhang and Mr. Qin didn't speak. They just looked at the busy welder in front of them and the people around them.

The requirements of the design drawing are one thing, but whether it can be produced according to the requirements is another matter.

This is something they have experienced firsthand!

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

"Dragon scale welding?"

The people who followed Mr. Qin looked at it for a while, and suddenly He opened his mouth and introduced.

“Yes, this is a superb welding method! Of course, dragon scale welding is just a skill, and the skills are different!”

"Some dragon scale welding is only a little higher than ordinary welding."

"But some welding is completely on another level!"

Mr. Chen nodded after hearing this. Got it.

“I remember this was the last skill competition held in the machinery factory!”

Liu Huaimin quickly answered from the side and said, “Yes, the chief has a good memory!”

"However, our comrade was defeated in the competition and only got second place!"

"The first place was won by..."

"It was won by our comrades from the Third Machinery Department!" 
Old Zhang on the side suddenly spoke.

But there is not much joy on the face!

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

But the person who followed Mr. Qin continued,

“But those who can master it at an advanced level can be counted on two hands in the country.”
 "The person in front of me is definitely an eighth-level master."

After the person finished speaking, he felt a little uneasy, and then said, "In this case, they are likely to complete the above data requirements."

"Really?"

"Well, it should be true."

Mr. Qin'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 this dragon scale welding technology. They should lack some heat.”

Mr. Qin couldn't hold his breath after hearing this.

The Dangtang Logistics Department does not have as many talents as a machinery factory.

If you say it, it will make people laugh.

Mr. Zhang and Mr. Chen listened nearby, both of them were speechless.

Mr. Zhang is because their Third Machinery Department has such a master, who is even more powerful than the person in front of him.

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

Isn’t it also a kind of helplessness to have a master but not be able to do fine work?

Chen Laowuyu was happy and speechless.

The machinery factory really made him face.

But they soon focused their attention on the front.

"Okay!"

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

When I saw Mr. Chen and the others, they immediately became cautious and a little at a loss.

Liu Huaimin looked at everyone, and then said, "You can do whatever you want, the chief is just here to take a look!"

Hearing this, Zhang Guanyu and Liu Daming made eye contact. , then nodded and continued.

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

Zhang Lao and others knew that they were checking the welding situation.

After a while, there was no problem with the initial inspection.

This also confirmed everyone’s suspicions. The middle-aged man in front of him was truly an eighth-level master.

“Send it for inspection!”

Liu Daming clapped his hands, looking forward to it.

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

At this time, Mr. Chen and the others didn’t say much, they just stepped forward and watched.

Director Zheng on the side handed over the design drawing.

At first glance, this drawing was drawn by someone with some enthusiasm.

So detailed!

Lao Zhang and Lao Qin brought people to the shell and started comparing them with the design drawings.

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

Not to mention, there are some similarities between the two.

As far as the overall appearance of the shell is concerned, that’s about it!

Liu Huaimin called Zhang Guanyu to come forward to explain. Yang Xiaotao was not available in this regard, so Zhang Guanyu could only be used.

"You have achieved such high precision requirements?"

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

In his impression, the accuracy requirements of their engine at this position were less than half!

Zhang Guanyu looked at it, then rubbed his nose, "Chief, this is where the pressurized warehouse is placed. We tried three times and finally found a way to make it. Now it can meet the accuracy requirements."

Hearing this, Mr. 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 you pack these people up and take them back.
