1959: Carrying the achievement system, she rolled

To make armor-piercing bullets, you first need to understand the basic composition of ammunition and the differences and connections between armor-piercing bullets and other types of ammunition.

There are also armored targets, the principles of armor-piercing projectiles, projectile materials and manufacturing technology, etc.

At present, they only know about armored targets. The tanks equipped by the Bear Country are mainly T-54 and T-55 tanks.

The T-55 tank is a simplified version of the T-54 tank, which means literally that it is both economical and simplified.

As for the rest of his knowledge, Qin Chulong was not discouraged. He took Wan Ping and Du Yimeng to the library of the institute.

The books here are very diverse, and most of them are about military engineering.

The three teachers and students spent a full half month in the library and did not gain nothing.

At least in a military magazine of the Bear Country, they saw an introduction to armor-piercing bullets. Although it was only a few words, at least they knew that armor-piercing bullets consist of several parts: wind cap, capped projectile body, ammunition belt and fuse.

Although there are only a few names, each name represents a huge set of data and requires a long period of practice and exploration.

Even the Russian Empire itself would not believe that someone would be crazy enough to have the unrealistic idea of ​​creating armor-piercing bullets based on a few superficial sentences in a military magazine.

No one would have thought that in 58, nine teachers and students from Tsinghua University would create a CNC machine tool based solely on an A9-sized advertising paper from the Soviet Union.

"What do you think?" Qin Chulong asked Xiang Wanping and Du Yimeng. There were originally 14 people in their second room, but 8 of them were transferred away after the engine test was completed.

Apart from the three teachers and students, the remaining three people served as accompanying testers, and now they are the only ones left in Room 2.

The institute is still continuing to research amphibious tanks, and the engine used is the same model as the Type 59 tank. In other words, these three people have the least time in the entire institute.

However, Director Song also said that they are the main force in researching armor-piercing projectiles. If support is needed, other laboratories will also allocate personnel to help and will never let them fight alone.

"Teacher, how about we go to the Bear Country and steal an armor-piercing bullet to study it!" Wan Ping's mind was blank, but he immediately came up with a good idea.

In fact, he didn't want to answer this question, but seeing Du Yimeng looking at him with her big eyes, as a top student, he could only answer it.

He wouldn't steal too many, just one and return it to them after studying it, right?

Even though he was a top student, his major was mechanics, and even though his hobby was weapons and ammunition, he had no idea about it.

Also, has the teacher forgotten that the three of them are mechanics? Three mechanics working on armor-piercing bullets, what a joke!

The main reason is that he has been spending every day in the library recently. Now, when he sees words, his head feels dizzy and his eyes go dark.

The high-intensity study was a bit too much for even a top student like him. I wonder how Du Yimeng managed to persevere?

He felt that she was like a mystery. No matter how intense the study was, she could always adapt to it. Isn't that strange?

The speaker may not have meant it, but the listener took it seriously. Du Yimeng's eyes lit up. She had space, so not only could she get armor-piercing ammunition, she might even be able to bring back a lot of tanks or something.

As for the safety issue, as long as she is careful enough, she will definitely be able to survive.

"Good idea!" Qin Chulong nodded, and his words made Wan Ping's eyes light up.

"You go ahead, I'll contact the other students and then go pick you up together." Qin Chulong said seriously.

He is not a man who likes to joke. Once he starts to joke, no one can tell whether he is telling the truth or not.

The smile on Wan Ping's face froze. His physical fitness was good, but it depended on who he was compared with. Compared with Du Yimeng, he was the stronger one.

But if he were asked to carry it out personally, it would be absolutely impossible. He would never admit it because he didn't trust his weak classmates.

Du Yimeng, who was a little skeptical, subconsciously shrank his head after hearing what Qin Chulong said.

She, who cherishes her life, felt that this idea was too crazy. She shouldn't be tempted by it. It was a sin.

"Student Du, you said before that you wanted to make armor-piercing bullets. It seems that you already have an idea. Tell me about it?" Qin Chulong set his eyes on Du Yimeng. He had no idea that she was talking nonsense at the time.

"Armor-piercing bullets are known for their strong arch and hard penetration, but if you want to penetrate thick armor, you have to rely on the core. Therefore, speed, weight, material and shape are the most important.

The first is the strength of the material, which affects the penetration ability of the armor-piercing projectile and its destructive power on the target.

We also need to consider the size issue. Small size means less wind resistance, which can reduce flight resistance, increase flight speed, and enhance penetration. "Du Yimeng has been studying hard during this period in the ocean of knowledge, not soaring in vain.

Plus, her research skill is at the intermediate level, with attribute points of 804. Some things, once mastered, can be mastered a hundred times.

When she first arrived at the institute, her eyes were blank. It was not because she was stupid, nor because her scientific research skills were not good enough.

But she had never come into contact with these things before. It would be strange if a mechanic suddenly became confused when she was working on weapons and equipment!

Wan Ping saw Du Yimeng talking with a look of surprise on her face. He really wanted to ask her, who is the top student and who is the poor student?

They went to the library together and walked together every day. He could pat his chest to ensure that she didn't slack off, but he couldn't be so perverted.

wrong……

Compared with her, it seems like he is the one who is being lazy, right?

A top student who was once so awesome was actually surpassed by a poor student. What does this mean?

It means he's not trying hard enough...

"Your idea is very good!" Qin Chulong nodded with satisfaction. He was very pleased with her growth!

When he first started giving them special treatment, her eyes were either filled with confusion or clear stupidity.

When she was looking for information in the library, she would ask him when she encountered something she didn't understand.

From being confused to seeing those eyes becoming brighter and brighter, he knew that his hard work had not been in vain.

The most important thing is that she now has the spirit of hard work and perseverance, unlike before when asking her to work overtime was like asking her to die.

Once, when he was looking up information until midnight, he asked her to go back and rest, but she looked at him with a puzzled look on her face.

At that moment, he knew that the student who once gave him a headache had changed.

As soon as Qin Chulong said this, Du Yimeng and Wan Ping looked at him with sharp eyes, waiting for his next words.

"For the time being, we will follow this idea as the research direction. We will use the most stupid method and cross the river by feeling the stones. We will test it step by step, and move on to the next step after the success." Qin Chulong said in a firm tone.

His words also made the two people's eyes light up. At this moment, they didn't care whether they could succeed or not.
