Siheyuan Great Craftsmen

"Well, it really has to be kept secret. I'll arrange it right away!"

After waking up, An Chaojun instantly understood the seriousness of the matter and nodded solemnly.

Originally, the situation on the peninsula had been caused by the lack of powerful artillery, which had already made the Bald Eagle retreat step by step. Now that he had the artillery steel and the artillery was manufactured, he believed that the situation on the peninsula would soon be reversed.

Such a national treasure cannot be overemphasized no matter how much importance we attach to it.

Steel Rolling Mill, Technical Department Office.

“Finally finished!”

Zhou Tian put down the last stroke, stretched his wrist, let out a breath of relief, put down the pen, stood up and stood at the window, looking at the black smoke billowing over the steel mill in a daze.

整整一个月，他耗费了整整一个月的时间，才将 M-1A2 式和 M-1A2E3 式 155 毫米榴弹炮的设计图绘制完成。

At this moment, he felt extremely relaxed. Thinking back to this busy time, he turned his head and looked at the nearly 700 drawings on his desk. He felt that everything was worth it.

After all, this represents the development of the domestic military industry and also means the strengthening of national defense capabilities.

Especially in the design of artillery shells, he not only used a lot of knowledge in aerodynamics, chemistry, materials science, but also a series of knowledge such as blasting science, before he was able to design a series of artillery shells.

It can be said that the design of the shells alone consumed nearly half a month's worth of his energy and drained him completely.

If it were not for the assistance of the virtual space in his mind, he dared to assert that even a bald eagle could not be designed without hundreds of scientists spending a year or two.

Fortunately, everything was worth it. In half a month, he not only designed different types of artillery shells, but also a lot of special shells and auxiliary shells. Among them, there are not only powerful explosive shells, armor-piercing shells, and armor-piercing shells for attacking targets, but also auxiliary illumination shells, smoke bombs, propaganda shells, and training shells and training shells for training or performing special tasks.

It can be said that he successfully designed everything he could think of.

You know, the design of each type of ammunition is extremely complex. Not only must the initial velocity, range, altitude, and flight stability of each type of ammunition be considered, but also the appropriate projectile structure, explosive type, and charge amount must be designed according to the type and characteristics of the target to achieve the maximum killing effect.

It is also necessary to ensure the accuracy of the shells during the firing process and reduce dispersion, while ensuring the reliability of components such as fuses and propellants to avoid premature explosions, duds and other malfunctions.

Another consideration is whether the projectile material has sufficient strength, toughness and fatigue resistance, while taking into account cost and machinability, whether it is possible to mass produce, and its universality in production.

All these difficulties need to be overcome one by one, so that it can be considered a qualified ammunition. This is also the reason why he thought that the shell design might become the biggest obstacle to the subsequent development of artillery steel when he drew the design drawings.

Fortunately, everything went smoothly. With the help of the virtual space in his mind, he overcame these problems one by one, and now all that was left was to put it into production and verify it.

"I don't know when Brother Song will come back. This guy has been gone for three days!"

Thinking about how he had sent Song Weiguo away using the quenching process for blast steel, he now actually missed this guy a little.

现在 M-1A2 式和 M-1A2E3 式 155 毫米榴弹炮的设计图已经完成，他似乎也该正式处理厂子里的事务了。

Although he had the help of his subordinates in the technical department, the progress in the production of cylindrical grinders was still slow. He had given them the task of cylindrical grinders with the intention of training them.

But he overlooked one thing, that is, these people have not yet established enough prestige in the factory, and many times, the workshop directors will not give them face.

In addition, the factory's tasks became increasingly heavy during this period, and the factory director did not personally issue production tasks for external cylindrical grinders, so the production of external cylindrical grinders came to a standstill.

A month passed and only eight cylindrical grinders were produced.

Thinking of this, Zhou Tian put all the design drawings on the table into the space, put on his cotton coat, and walked towards the technical department.

Before entering the technical department, Zhou Tian heard a burst of angry cursing coming from inside.

"Damn it, Guo Yu from the Fifth Workshop is such a piece of shit! Didn't we just ask the workers to produce a batch of guide rails for cylindrical grinders? He promised us, but in the blink of an eye he forgot everything we asked him to do. When we asked him about it, he even made excuses, saying that the factory's mission was more important. I don't think they take our technical department seriously at all!"

"Yes, let alone the fifth workshop, the newly built sixth and eighth workshops are all like this. When we first approached these workshop directors, they all promised, but when you asked about the progress, they all hesitated and started to complain! What's going on? Don't they use the cylindrical grinders after they are produced?"

"That's right, I finally understand. These people are not looking down on our technical department, they are clearly trying to make things difficult for us!"

The discussions of the people in the technical department continued to reach Zhou Tian's ears who was standing outside the door. The more he listened, the heavier his expression became, gradually turning into a cold chill.

This is not to embarrass the technical department. Judging from what the audience said, this is clearly a slap in the face.

Thinking of this, Zhou Tian gave up the idea of ​​going into the technical department to inquire about the situation of the cylindrical grinder. He turned and left the technical department and walked towards the factory director's office.

He would like to ask the factory director whether he, as the director of the technical department, really has no say in the factory.

Just before he arrived at the factory director's office, he saw a middle-aged man with many spots on his face walking out of the factory director's office, bending over and smiling. When he saw Zhou Tian, ​​his expression changed immediately, he glanced at him with his eyes, snorted coldly and walked past Zhou Tian.

This made Zhou Tian feel puzzled. If he remembered correctly, he seemed to have no connection with this person. But why did this person have such deep hostility towards him?

However, Zhou Tian soon stopped taking this man to heart and went to the factory director's office and knocked on the door.

"Come in!"

As the factory director's voice came out, Zhou Tian pushed open the door and walked in, only to see Factory Director Yang buried in his desk, apparently correcting documents.

"Director!"

Zhou Tian walked over and spoke softly.

"Oh, it's Xiaotian, have you finished your work over there?"

When Director Yang heard the familiar voice, he looked up and saw that it was Zhou Tian. He quickly put down the pen in his hand and asked with a smile.

"Well, I'm done. Director, I came here today to ask about the cylindrical grinder!"

He remembered that he had already informed Director Yang about the cylindrical grinder, so he was not worried that this matter would cause Director Yang's dissatisfaction.

"Well, you want to talk about the production of cylindrical grinders, right?"

Unexpectedly, Director Yang suddenly spoke, which stunned Zhou Tian for a moment.

"Director, do you know everything?"

After a long time, Zhou Tian reacted, his face suddenly turned ugly, and he asked.

"Well, this is what I ordered!"

Director Yang did not mince words and said them directly, which made Zhou Tian unbelievable.

"why?"

Zhou Tian felt as if his heart had stopped beating in an instant, and asked with difficulty.

"Oh my god, it's not that I don't want to produce circular grinders, but the reality doesn't allow it!"

Director Yang seemed not to notice Zhou Tian's ugly face and began to talk freely: "You also know how heavy the tasks in the factory are recently. Even I wish I could be split in half. Although the cylindrical grinder is important, at present, the most important thing for our factory director is to complete the tasks given to us by our superiors. As for the cylindrical grinder, I plan to complete the tasks above first, and then we will produce. What do you think?"
