"What?"

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

Yang Xiaotao shook his head, "Think of something, nothing else!" ”

Director Zheng did not doubt him, watched the materials take away, and followed to see the situation.

Yang Xiaotao was a little skeptical, it seems that these two copper alloys have similarities, and it can be seen in the name that they should be doped with copper, and the color is similar.

But it's just a matter of appearance, who knows how it will work?

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

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

With the support of the three machine departments, the work was carried out again.

"Uncle Zheng, why do you have to bother you to run for such a little thing, just come over and come alone."

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

"You still say, I heard that you are going to make an eight-cylinder diesel engine, and Lao Tzu was asked by his superiors to come."

After taking two sips, Lao Zheng said with an unhappy face.

"Lao Tzu is also busy over there, it's good for you to have a phone call, you can't do the work, and you have to prepare things."

"Just this little thing, or squeezed out of this tooth, we all use it tightly."

Yang Xiaotao smiled helplessly when he heard this, he encountered this kind of problem when he was manufacturing Daystar, and he took great pains to make that bit of tungsten steel, and he almost lost Daystar.

Now that I think about it, after so long, it seems that the domestic metallurgical industry is still standing still.

This is true for tungsten steel.

This is still the case with copper alloys today.

You know, the machine before the war used tungsten steel, although I don't know where it came from, but the gap is too big.

In my heart, I silently gave spiritual encouragement to the comrades in the metallurgical industry, hoping that they would not delay any longer.

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

"Xiao Tao, you can design this drawing."

Director Zheng looked at the drawings on the side, picked up one from time to time, and compared it on the semi-finished product, "Last time I talked about researching the four-cylinder engine, you also said that you wanted to study it, and you had to wait, but I didn't expect that you turned your head and made an eight-cylinder directly?" ”

"You kid, are you sincere?"

Yang Xiaotao shrugged, "The four-cylinder was really not made at the time, but after the design was completed, I found out that the four-cylinder engine is such an armored car, it is simply a thin-skinned dumpling. ”

Director Zheng also nodded when he heard this, "Yes, we also had this consideration at the beginning, in order to complete the military's goals, we thought a lot and investigated a lot!" ”

"I originally wanted to import an engine to do it, but if this thing is imported, it is likely to be stuck at a critical time, so I can only develop it myself!"

"The existing engine, you did a good two-star, but the power was not good, so I hit the idea on the four-cylinder engine. All designs are geared towards this technology. ”

"But how to design, it is also to take care of one or the other, take care of the protection force will lose speed, take care of the speed to reduce the load..."

"It was originally used to transport people, but what is the use of fewer people?"

"So halfway through the research in the back, I had to give up!"

Director Zheng watched from the sidelines and couldn't stop sighing.

At the beginning, their three aircraft departments were ready to undertake this task.

But the reality is so cruel that this thing is much harder than a truck.

The engine, in particular, stumped a group of experts from the third machine department.

At first, they also thought of using the Type 59 engine, that is, the engine of the T54A from the Alliance.

After all, the design drawings and production process of this engine from the alliance have been thoroughly eaten by the factory in Lucheng, as long as the other party provides the engine, their three machine departments can design the first armored transport vehicle in China.

However, reality slapped them in the face again.

Because of the tension with the alliance, the alliance has stopped the supply of relevant components and materials in recent years.

Now the engines produced by Lucheng 59 are not enough for their own use, how can they have excess to share with others?

Moreover, because of the material, the Lucheng factory is also looking for alternative materials in China, but after so many years, a lot of materials have been used, but the engine made always has this and that problem, and it is estimated that it cannot meet the task requirements.

Besides, everything in the alliance has the commonality of stupidity, and if it sounds good, it is solid, and if it is bad, it is shoddy.

Such an engine, they are afraid of the three engine departments in their hearts!

Therefore, we can only seek the road of independent research and development, and this is how we found a machinery factory.

According to the plan of the third engine department, a light assault vehicle was made, so the engine chosen was a four-cylinder diesel engine.

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

Unexpectedly, because of the aviation mission, the superiors considered it and handed over this task to the first aircraft department.

What I didn't expect was that the first machine department was transferred to the machinery factory.

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

Yesterday he reported the progress of the research in the office, and then Zhang Lao received a call from the First Aircraft Department.

He still remembers that when Zhang Lao put down the phone, the whole person was in a state of confusion.

That's why he made a personal trip today.

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

Yang Xiaotao looked at him incomprehensibly.

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

Director Zheng suddenly became serious, and Yang Xiaotao didn't hide it, he had already said it last time when he explained why he wanted to use an eight-cylinder engine.

There's nothing to hide at the moment!

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

Director Zheng swallowed his saliva, what the emotional family said before was not that it couldn't be done, but that there was no need to do it.

Smack

Stretched out his hand and patted Yang Xiaotao's shoulder, "You kid, you are really not an ordinary person!" ”

On the other side, everyone was 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 there is a problem with one of the same batch, the others are not much better.

Because the materials are precious and cannot be wasted, only Liu Daming and Hou Baowei can do it, and Yang Xiaotao can also be killed, but Liu Huaimin asked him to accompany the comrades of the Third Machine Department, and he will have to assemble it after a while, so he was not allowed to end.

Although there are two people, they are highly skilled, and it doesn't take much time to operate the machine tool to make the parts that are needed.

Yang Xiaotao took a look, and then began to assemble the engine.

It's just as fast.

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

Needless to say, someone immediately brought diesel and water to add it, and Yang Xiaotao took matters into his own hands and turned on the engine.

Knock knock...

Unlike the sounds of the morning, this time it sounded powerful.

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

"Wait, arrange for someone to watch."

Yang Xiaotao is also a normal heart, knowing that the final result has to wait and see, and the inspection can't detect anything wrong now.

This incident also reminded Yang Xiaotao that the hidden problems of the machine, or the problems that were not exposed, could not be detected by faulty scanning glasses.

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

However, in the future, it will be necessary to observe the manufacture of high-end equipment for a while longer.

Xiao Guo nodded and instructed to prepare for the test.

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

"Uncle Zheng, this machine is going to run all night, if you have time, go to the house for a meal?"

Director Zheng looked at the time, although it was not yet time to get off work, but he came today, and he also had the heart to take a look.

"How's your dad doing?"

Asked about Ran's father, Yang Xiaotao pushed with both hands, "You know, his time in the Seventh Machine Department is longer than the time at home." ”

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

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

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

"Lao Ran is such a character, when he was in the northwest before, he encountered problems, and he didn't rest all day and night, I remember that there was a data that didn't match what the alliance gave, and Lao Ran took people to calculate it over and over again."

Thinking of his days in the northwest, Lao Zheng not only did not sigh and sigh, but felt a kind of supreme glory.

syllable

"You kid, you almost stayed there."

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

If he had been asked to stay, he would have chosen to stay.

Even if it will have an impact on Ran Qiuye because of this.

But in terms of the choice of everyone and the small family, Yang Xiaotao still has his own insistence.

The two came to the office as they spoke, and after entering the door, Lou Xiao'e prepared tea, and the two sat down to chat.

Seven machine departments.

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

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

Beside him, Qian Lao looked at him with a distressed face, although his words were firm, but with sad regret.

"Chief, no."

Father Ran wanted to get up, but Qian Lao stepped forward and held it down.

"Chief, really, it's okay, I'll just lie down for a while."

"Now that we have cooperated to a critical time, Team Leader Zhong has given solutions according to the problems we listed, and they have made changes, I"

"Comrade Ran Zhiqiang."

Without waiting for Father Ran to finish speaking, Qian Lao solemnly spoke again.

Father Ran looked at Qian Lao.

"Wende."

"You're tired, where can I find a competent director?"

"Chief, me?"

"I know, you want to prove yourself as soon as possible, and respond to those bullshit remarks with bullets and no guns as soon as possible, and I want to too."

"I also want to slap them in the face and tell them with facts that what they can do, we, the Chinese people, will definitely be able to do it, and 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 envy and regret."

Qian Lao said movingly, just like the question he was asked when he returned to China, 'When you go back, are you planting apples?' ’

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

Father Ran opened his mouth but couldn't speak, it was precisely because he knew what happened to the person in front of him, so compared with the person in front of him, he was lucky.

Therefore, what he said was also his heart.

"Now, our apple trees are about to take root, and I hope to see them with you."

"I hope that we will plant more apple trees and plant them all around the motherland to blossom and bear fruit."

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

"Do you understand?"

"Understood! Chief, I understand! ”

Father Ran stopped struggling and lay on the marching bed.

"If you understand, you can go home and rest."

"By the way, bring these things back and say sorry to my brother and sister, we have taken up too much of your time."

Father Ran's face felt more uncomfortable when he heard this, but when he thought of his wife waiting for him at home, he felt a sense of shame in his heart.

This is not the northwest, I am a family person.

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 man was carrying something down at the door.

"Hey, that's not Lao Ran."

Lao Zheng smiled, "What about him during the day, this is the meeting?" ”

Yang Xiaotao is also curious, it is not easy for Ran's father to appear once.

The car stopped next to it, and Ran's father also found 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, saw Ran's father looking tired, and asked with great concern.

Yang Xiaotao came down to say hello to Ran's father, took the things in Ran's father's hand, and also felt that Ran's father's body was not quite right.

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 reacted, knew Lao Dao's intentions, and then nodded.

"Lao Zheng, why are you here?"

Ran's father was pleasantly surprised, and his old friend, who had not seen him for many days, appeared in front of him, and he felt a lot in his heart.

The two stepped forward and hugged their arms, "I went to Xiaotao and they have something to do, I didn't plan to come for a meal in the morning, I thought you wouldn't come back." ”

As he spoke, the two walked towards the courtyard.
