"It can't be wrong."

At this time, Mr. Zhang suddenly spoke.

"I have learned about the manufacturing process of aircraft engines in a machinery factory. In order to produce them, I specially studied titanium alloys."

"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 a hint of expectation in his heart.

I'm looking forward to seeing what the engine produced by the machine shop 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, had no idea 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...

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's not as good as the engines in the Logistics Department of the Third Machinery Department, it shouldn't 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 hear it roughly.

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, the boss of the machinery factory, and said, "Chief, look, I don't know much about this matter 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 machine 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 the design drawing can be met.

However, it is a bit more difficult to build 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, an afterburner housing and other parts.

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 started trial manufacturing.

I just tried 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 accuracy, 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.

Looking at Shi Hanzi who was lighting up the welding rod, Zhang Guanyu's hands started to sweat.

This is the third time.

I've done this twice before without success.

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

However, 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 back and put his finger on his mouth, "Shhhhhh, don't say..."

"Um, secretary. Also, there is 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 started asking.

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 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 a few 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.

By comparison, these parameter requirements are more stringent 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 was prepared for 'peepers' like them.

The two of them were in a bad mood, and then walked up 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, nothing Yang Xiaotao designs is simple.
