"What?"

Director Zheng didn't hear clearly what Yang Xiaotao said, so he raised his head and asked.

Yang Xiaotao shook his head, "I remembered something, nothing else!"

Director Zheng did not doubt his presence, watched the materials being taken away, and followed to see the situation.

Yang Xiaotao was a little skeptical. It seemed that the two copper alloys were similar. It could be seen from the name that they were mixed with copper, and the colors were similar.

But this is just based on appearance, who knows how it will work?

Just like steel, many varieties look similar in color, but their hardness and strength are vastly different.

At the moment, Yang Xiaotao didn't think much about it. What mattered was the engine in front of him.

With the alloy provided by the Third Machinery Department, work started again.

"Uncle Zheng, why do I have to bother you with such a small matter? Why don't you just come over and be alone?"

Yang Xiaotao took out the cigarette and Lao Zheng lit it.

"What are you talking about? I heard that you were going to build an eight-cylinder diesel engine, so I was asked by my superiors to come."

After taking two puffs, Lao Zheng said with an unhappy expression.

"I'm also busy over there. It's better for you to just call me. I can't do any work. I still have to prepare things."

"It's just this little thing, it's squeezed out from the gap between the teeth. We use it as much as possible."

Yang Xiaotao smiled helplessly after hearing this. He had encountered this kind of problem when he was making Daystar. He had worked so hard to get that little bit of tungsten steel and almost lost Daystar.

Thinking about it now, after all this time, it seems that the domestic metallurgical industry is still standing still.

Tungsten steel is like this.

This is still the case with current copper alloys.

You know, the machines before the war used tungsten steel in my childhood. Although I don’t know where it came from, the difference is probably too big.

In my heart, I silently gave spiritual encouragement to my comrades in the metallurgical industry, hoping that they would stop holding back.

Director Zheng threw the cigarette butt on the ground, stamped it out, and then walked to the front.

"Xiao Tao, the drawing you designed is fine."

Director Zheng looked at the drawings on the side, picking up one from time to time and comparing it with the semi-finished product, "Last time when I talked about studying the four-cylinder engine, you said you wanted to study it and wait. Unexpectedly, you turned around and said

Did you make eight cylinders directly?"

"You kid, did you do this on purpose?"

Yang Xiaotao shrugged, "It is true that the four-cylinder one was not built at the time, but after the design was completed, I realized that the armored vehicle with the four-cylinder engine was basically a thin-skinned dumpling. If I handed it over, I guess it would be good for transporting goods and people.

Just giving people heads."

Director Zheng nodded after hearing this, "Yes, we also had this consideration at the beginning. In order to achieve the military's goals, we considered a lot and investigated a lot!"

"Originally I thought about importing engines, but if this thing was imported, it would probably get stuck at a critical moment, so I had to develop it myself!"

"With the existing engines, the Double Star you made is good, but the power is not good, so we decided to focus on a four-cylinder engine. All designs are based on this technology."

"But no matter how you design it, you have to pay attention to one thing and lose the other. If you take care of the protection, you will lose the speed. If you take care of the speed, you will have to reduce the load..."

"It was originally used to transport people, but what's the use if there are fewer people?"

“So after halfway through the research, I had no choice but to give up!”

Director Zheng watched from the side and couldn't help but sigh.

When the Third Aircraft Department took on this task, they were prepared to do a big job.

But the reality is too cruel, this thing is much more difficult than a truck.

The engine, in particular, stumped a group of experts from the Third Machinery Department.

At first they also thought about using the Type 59 engine, which was the T54A engine that they obtained from the Alliance.

After all, the engine, design drawings, and production process obtained from the alliance have been thoroughly understood by Lucheng's factory. As long as the other party provides the engine, their three machine departments can design the first armored transport vehicle in the country.

However, reality slapped them again.

Due to the tense relationship with the alliance, the alliance has stopped supplying related parts and materials in recent years.

Now the 59 engines produced by Lucheng are not enough for our own use, so how can we share the excess with others?

Moreover, due to material reasons, Lucheng Factory is also looking for alternative materials in China. However, after so many years, a lot of materials have been used, but the engines produced always have some problems, and even after using them, they are probably not up to par.

Task requirements.

Besides, all things in the Alliance have the common characteristic of being silly and thick. If they sound good, they are solid, but if they sound bad, they are shoddy.

The third machine department is afraid of using such an engine!

Therefore, we could only seek the path of independent research and development, and then we found a machinery factory.

According to the plan of the Third Machinery Department, a light assault vehicle was made for cross-fertilization, so the engine chosen was a four-cylinder diesel engine.

To this end, not only people were sent to the machinery factory to study, but a special task force was also set up.

Unexpectedly, due to the aviation mission, the superiors gave this task to the First Aircraft Department after consideration.

What was even more unexpected was that the First Machinery Department was transferred to the Machinery Factory.

What they didn't expect was that the machinery factory actually came up with a research plan.

Yesterday, he reported the research progress in his office, and then Mr. Zhang received a call from the No. 1 Machinery Department.

He still remembers that when Mr. Zhang put down the phone, he was in a daze.

This is also the reason why he made a trip in person today.

Looking at the busy scene, Director Zheng looked at Yang Xiaotao, suddenly thought of something, and quickly reacted, "What did you just say?"

Yang Xiaotao looked at him confused.

"I mean, you just said that the four-cylinder engine has been designed?"

Director Zheng suddenly became serious, and Yang Xiaotao didn't hide it. He had already mentioned this when he explained why an eight-cylinder engine was used last time.

There is nothing to hide now!

"Yes, it was because of the design of a four-cylinder engine that I realized it was insufficient in power, so I used an eight-cylinder engine to replace it!"

Director Zheng swallowed. What people said before was not that it couldn't be done, but that it wasn't necessary.

He reached out and patted Yang Xiaotao's shoulder, "You kid, you are really not an ordinary person!"

On the other side, everyone is busy.

If there is a problem with three parts, it does not mean that only three parts need to be replaced, but that all three series need to be replaced.

After all, if one of the same batch has a problem, the others will not be much better.

Because the materials were precious and could not be wasted, only Liu Daming and Hou Baobao took action. Originally, Yang Xiaotao could have been dismissed, but Liu Huaimin asked him to accompany the comrades of the Third Machinery Department, and since they would have to assemble it later, they did not let him go.

.

Although the two people were small, they were highly skilled and did not spend much time manipulating the machine tool to make the required parts.

Yang Xiaotao took a look and then started assembling the engine.

The speed is also very fast.

By evening, an eight-cylinder engine had been assembled.

No need to explain, someone immediately brought diesel and water to add it, and Yang Xiaotao started the engine himself.

Dong Dong Dong…

Different from the sound made in the morning, the sound this time sounded powerful.

The people around him had gained experience and were not in a hurry to cheer, although Director Zheng next to him had already raised his hand.

"Pang workers, arrange for someone to watch."

Yang Xiaotao is also normal, knowing that the final result will have to wait and see, and the current inspection cannot find anything wrong.

This incident also reminded Yang Xiaotao that fault scanning glasses cannot detect hidden problems in the machine, or problems that are not exposed.

I haven't encountered it before, it's because the requirements for materials are not high.

But in the future, the manufacturing of advanced equipment must be observed for a longer period of time.

Pang Guo nodded and ordered to prepare for the test.

Everyone dispersed, Secretary Liu asked Yang Xiaotao to greet Director Zheng, and then led others to continue working.

"Uncle Zheng, this machine will run all night. If you are free, would you like to have a meal at home?"

Director Zheng looked at the time. Although it wasn't time to get off work yet, he was here today and wanted to take a look.

"How's your dad doing lately?"
