Scholars in the courtyard

"It can't be wrong."

At this time, Mr. Zhang suddenly spoke.

"I have learned about the aircraft engine manufacturing process in the machinery factory. For production and manufacturing, I specially researched titanium alloy."

"Also, the design coefficient requirements are very strict and no changes to the design drawings are allowed."

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

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

Looking forward to what the engine produced by the machine shop will look like.

Compare it with their engine that uses 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, dereliction of duty is another matter.

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

Then Hongxing Machinery Factory doesn’t have another ‘way to make money’?

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

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

What's more, something happened in the logistics department.

Therefore, 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 getting 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, his face became even more ugly.

"What did you say? What's the reason?"

Mr. Qin asked displeasedly, "What about pills? What about the details? Please tell me clearly."

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

Then he looked at Mr. Chen, who was the boss of the machinery factory, "Chief, look, I don't know much about this matter. How about waiting for Comrade Yang Xiaotao to come 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, "Now that 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 to learn about the machine factory's research on aircraft engines, and 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.

However, it is a bit 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 propulsion 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 started trial manufacturing.

I just did it several times without success.

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 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 started to sweat.

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 great 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 were still sounds in my ears.

"Director Zhang!"

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

"Uh, secretary. Also, the chief."

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

"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 on the side had stern looks.

Everyone quickly moved out of the way. When Mr. Chen and the 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, and was concentrating on his work.

Even if a few of them arrived, they didn't 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, and several people can confirm it at a glance.

Then one drawing after another was 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.

Moreover, 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.

But for comparison, the requirements for this parameter are more stringent than 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 was 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 Director Zheng's words.

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

Neither Mr. Zhang nor Mr. Qin spoke. They just looked at the busy welder in front and the people around them.

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

This is something they have experienced firsthand!

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

"Dragon scale welding?"

The people who followed Mr. Qin looked at it for a while, and then suddenly opened their mouths to introduce.

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

"Some dragon scale welds are only a little higher than ordinary welds."

“But some welding is on another level entirely!”

Mr. Chen nodded after hearing this. He had understood this kind of thing before.

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

Liu Huaimin quickly answered and said, "Yes, the chief has a good memory!"

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

"The first place was..."

"Acquired by our comrades from the Third Machinery Department!"

Mr. 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 to say,

"But if you can master it at an advanced level, you can count the number of people in the country who can do it on two hands."

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

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

"real?"

"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 kind of dragon scale welding technology. They should be a little short of heat."

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

The Dangtang Logistics Department actually doesn't have as many talents as a machine factory.

If you say it out loud, 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 machine shop really helped him earn face.

But they quickly focused on the front.

"alright!"

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

Only then did I see Mr. Chen and the others, and 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, the initial inspection showed no problem.

This also confirmed everyone's suspicion that the middle-aged man in front of him was truly an eighth-level master.

"Send it for examination!"

Liu Daming clapped his hands, looking forward to it.

Someone immediately stepped forward, worked together to lift the welded parts, and then set 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.

This drawing, at first glance, was drawn by someone with some enthusiasm.

So detailed!

Old Zhang and Old Qin led the team to the shell and started to compare the design drawings.

At the same time, they also compared them with their own work in their minds.

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

The overall appearance of the shell is almost the same!

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

"You have achieved such high precision requirements?"

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

In his impression, the precision requirements of their engine at this position were reduced by half!

Zhang Guanyu looked at it, then rubbed his nose, "Chief, this is where the pressurized chamber is placed. We tried three times and finally found a way to make it. Now it can meet the precision 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 these people were packed and taken back.
