Scholars in the courtyard

"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 had similarities. It could be seen from their names that they should be 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 his 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 busy over there too. It would be better if you just give me a call. 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 problem when he was making the Venus. He had worked so hard to get that little tungsten steel and almost lost the Venus.

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

This is true for tungsten steel.

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 the comrades in the metallurgical industry, hoping that they would stop holding back.

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

"Xiao Tao, you designed this drawing, it's okay."

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's true that the four-cylinder one wasn't 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 fine 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!"

"I originally thought of importing engines to make it, 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 parties are designing with this technology in mind."

"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 wanted 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 relevant parts and materials in recent years.

Now Lucheng doesn't produce enough 59 engines for its own use. How can there be any excess to share 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 it is estimated that even after using them, they will not reach the standard. Mission 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 was 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 crossover, 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 on the research progress in his office, and then Mr. Zhang received a call from the First Machinery Department.

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

This is 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 the emotional people said before was not that it couldn't be done, but that there was no need to do it.

snap

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 must 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 glanced at it and then began to assemble the engine.

It's also 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.

"Panggong, arrange for someone to watch."

Yang Xiaotao is also normal. He knows 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?"

When asked about Ran's father, Yang Xiaotao pushed him with both hands, "You know, he spends more time in the Seven Machinery Department than at home."

"Now my mother-in-law is helping me take care of the children, and I can't see her anymore."

"To be honest, I haven't seen him in almost two months."

The two walked into the office. Lao Zheng listened and nodded silently.

"Lao Ran has such a temper. When I was in the northwest, when I encountered a problem, I would not rest all day and night. I remember there was a piece of data that the alliance gave me, so Lao Ran and his people calculated it over and over again."

Thinking of his days in the northwest, Lao Zheng not only did not lament, but felt a sense of supreme glory.

Snapped

"You kid, you almost stayed there."

Lao Zheng smiled maliciously, and Yang Xiaotao also learned about the situation from Lao Dao, and was not happy about it.

If he needed to stay at that time, he would definitely choose to stay.

Even if it will affect Ran Qiuye.

But when it comes to choosing between everyone and Xiaojia, Yang Xiaotao still has his own persistence.

The two came to the office as they talked. After entering, Lou Xiaoe prepared tea and the two sat down to chat.

Seventh Machinery Department.

"Comrade Zhiqiang, I order you to go home and rest."

In the office, Ran's father was lying on the bed with a look of exhaustion on his face.

Beside him, Mr. Qian looked at him with a distressed expression. Although his words were firm, they were filled with sad regret.

"Chief, no need."

Father Ran wanted to get up, but Mr. Qian stepped forward and held him down.

"Chief, it's okay. I just need to lie down for a while."

"Now that our cooperation has reached a critical stage, Team Leader Zhong has provided solutions based on the problems we listed, and they have made changes. I"

"Comrade Ran Zhiqiang."

Before Ran's father could finish speaking, Mr. Qian spoke solemnly again.

Father Ran looked at Mr. Qian.

"Wende."

"You are tired and lying down. Where can I find a capable director?"

"Chief, me?"

"I know that you are thinking about proving yourself as soon as possible and responding to those bullshit remarks about bullets but not guns. I want to do that too."

"I also want to slap them hard in the face and tell them with facts that we, the Chinese people, can definitely do what they can do, or even do better."

"I want to plant an apple tree here more than you do."

"Let China become the Garden of Eden, and let those who look down on us be envious and regretful."

Mr. Qian said with emotion, just like the question he was asked when he returned to China, "Are you going to grow apples when you go back?" ’

And his answer was equally firm, ‘As long as the motherland needs it, I am willing. ’

Father Ran opened his mouth but was speechless. It was precisely because he knew what happened to the person in front of him that he was lucky compared to the person in front of him.

Therefore, what he said was also the voice of his heart.

"Now, our apple tree is about to take root and sprout. I hope I can see it with you."

"I hope that we can plant more apple trees around the motherland and they will bloom and bear fruit."

"I think we can work hard together, witness the moment of fruition together, and share this honor together."

"Do you understand?"

"Understood! Chief, I understand!"

Ran's father stopped struggling and lay down on the camp bed.

"If you understand, just go home and have a good rest."

"By the way, take these things back and say sorry to your siblings. We took up too much of your time."

Ran's father felt uncomfortable when he heard this, but when he thought of his wife waiting for him at home, he felt ashamed.

This is not Northwest, I have a family.

In the evening, at the entrance of the courtyard.

When Yang Xiaotao pulled Lao Zheng and Lao Dao back, he saw a jeep parked at the door.

In the car, a person was carrying something down from the door.

"Hey, isn't that Lao Ran?"

Lao Zheng smiled, "We were talking about him during the day, and now we meet?"

Yang Xiaotao was also curious. It was not easy for Ran's father to appear once.

The car stopped nearby, and Ran's father also spotted Yang Xiaotao and Lao Zheng. His face was stunned for a moment, and then he smiled.

"Lao Ran, you guy, why did you do this?"

Lao Zheng jumped out of the car and asked with concern when he saw Ran's father looking tired.

Yang Xiaotao came down to say hello to Ran's father, and took the things from Ran's father's hands. He also felt that something was wrong with Ran's father's body.

The old man next to him frowned and shook his head, approaching Yang Xiaotao, "I'll go back and get the wine."

The voice was very solemn. Yang Xiaotao realized what he was thinking and nodded.

"Old Zheng, why are you here?"

Ran's father was pleasantly surprised. An old friend he hadn't seen for a long time appeared in front of him, and he immediately felt a lot in his heart.

The two of them stepped forward and hugged each other, "I went to Xiaotao's place for some business. I didn't plan to come over for a meal in the morning. I thought you wouldn't come back."

As they spoke, the two walked towards the courtyard.
