Open an aircraft carrier to fight against Japan

Su Mao quickly asked, "What can you do?"

Lin Yuan knew that Luo Chaoying was going to use the advanced technology of the 21st century, so he couldn't help feeling a little proud, but when he was proud, he suddenly thought that Shen Wanqing said that the Japanese bought an official in the Machinery Bureau. Lin Yuan knew the name of this official. , but they don't know what he looks like, or whether he is in this group of people.

Lin Yuan hurried forward and said, "Old Luo, let's talk about this matter later."

But the officer was getting impatient. When Luo Chaoying and Su Mao were talking about professional skills, he couldn't understand a word. He shouted angrily, "What are you talking about? Come, someone, tie up this old thing!"

That Su Mao didn't look at the usual submissive and low-key appearance, but at this moment, like a crazy leopard, he yelled at the officer: "Don't make noise!"

The officer couldn't imagine that he would be like this at all, and he didn't care about pursuing his following crimes. He was stunned on the spot, Su Mao turned his head and asked Luo Chaoying: "What can you do?"

Lin Yuan quickly said, "Let's find a place where no one is around."

After all, Lin Yuan's official position was higher than that of the officer, and the officer had no choice but to watch Lin Yuan bring the two of them into a room.

After entering the room, Luo Chaoying said: "Whether it is a multi-layer barrel or a silk-wrapped barrel, their essential principles are the same, that is, before the gunpowder in the barrel explodes, an inward force is given to the barrel in advance, so that when When the gunpowder explodes, some of the pressure is offset."

"If we can use other methods to give the barrel an inward force, then we can achieve the goal without using multiple layers of barrel or wrapping silk outside the barrel. I know a kind of barrel called self-tightening barrel, but I don't know Has Mr. Su heard of it?"

Su Mao said: "I haven't heard of this thing, I don't know what it is?"

Luo Chaoying said: "If we add high-pressure liquid into the barrel, the high-pressure liquid will squeeze the inner wall of the barrel outward. If we can look at the barrel from a very microscopic point of view, then we can find that the barrel's Each part will deform, and the pressure value of these liquids is above the yield strength of steel, which means that the deformation of each part of the barrel is plastic, and the plastic deformation of the inner and outer layers of the barrel is different. When we remove the high-pressure liquid, the outer barrel will squeeze the inner barrel, which is equivalent to giving the inner barrel an inward force, so we have achieved the purpose of increasing the strength of the gun barrel."

Su Mao nodded repeatedly and said, "This is really a good idea!"

Luo Chaoying also said: "The strength of such a barrel will be twice that of an ordinary single-layer barrel! Moreover, the barrel treated in this way has many other benefits. For example, the life of the barrel will be greatly increased. , can save high-performance alloy steel.”

Su Mao thought for a while and said: "This is just the basic principle. There must be some other problems in engineering applications. For example, how much pressure should be selected for the liquid, and how should the device for adding liquid to the barrel be designed? Have you thought about it?"

Lin Yuan also remembered that Luo Chaoying didn't bring any technical materials, so he wondered how he would complete the design of this equipment?

Luo Chaoying smiled and pointed to her head, "Don't worry, they're all here."

Su Mao praised repeatedly, and said: "Old Luo, you are really a master! I saw you today." Then he turned his head to Lin Yuan, and said, "Master Lin, since Mr. Luo has such a great ability, why didn't you tell me earlier?" ?”

Lin Yuan said embarrassedly: "Didn't our ancestors have a saying that when the water is clear, there will be no fish, and when people observe it, there will be no disciples. I just want to be like everyone else."

Su Mao said: "Leave that officer to me to deal with." Then he turned and wanted to go out.

Lin Yuan grabbed him and asked, "Is there an official here called Xu Bin?"

Su Mao said: "Of course there is. He is the head of quality inspection, and all the products produced must go through his hands. How do you know him?"

Lin Yuan said, "Oh, I heard a friend mention him."

Su Mao nodded, turned and left.

Only Lin Yuan and Luo Chaoying were left in the room. Lin Yuan whispered to Luo Chaoying, "Old Luo, the Xu Bin I mentioned just now has been bought by Japanese spies. Be careful of him when you are here in the future. If he asks you, don't say anything."

Luo Chaoying asked: "What? Since he is a Japanese spy, why didn't he be arrested?"

Lin Yuan smiled and said: "Don't rush to catch him, there are other uses for keeping him, we will put on a show for him in a while, I will ask Su Mao to invite all the officials from the Machine Bureau, you give They give lectures, do you know what kind of artillery, which was not researched in our time, you will bring it up at the meeting later, let those little devils bother to study it!"

Luo Chaoying thought for a while and said, "Why don't I tell them about the laser cannon? It's not at 01:30 that it's so difficult to develop this thing, but I don't understand it very well, because the principle of the laser cannon has been compared with the traditional artillery. Totally different."

Lin Yuan said: "You can't talk about this! You think, little devils don't even know what a laser is. If you want to talk about developing a laser cannon, how can they believe it? If the technology gap is too big, they won't bother I’ve worked hard to research it, think again, is there something that you can see but can’t touch?”

Luo Chaoying said: "Well, I have a solution."

At this moment, Su Mao came in and said, "I have sent that officer and his people away."

Lin Yuan said: "Mr. Su, how about this, let Mr. Luo tell everyone about artillery."

Su Mao said: "That's great, I wish I could. There are very few people in the Machinery Bureau who understand these things."

Soon Su Mao called everyone together, and Lin Yuan specifically asked who Xu Bin was. Xu Bin was a middle-aged man, a little thin, and the mandarin coat on his body was almost washed and faded. He was holding a notebook and a pencil. , First write the date on the notebook, and then sit there upright, waiting for the start, just like a studious student.

Luo Chaoying said: "Today I want to tell you about the results of my studies."

"Today I want to discuss the rate of fire of the artillery with you. Everyone knows that the rate of fire of this artillery is very slow. Why? Because the barrel of the artillery is rigidly connected to the gun mount. When a shell is fired Afterwards, the barrel of the artillery must move backward together with the gun carriage, that is, recoil. If this recoil occurs, the previously set shooting elements will no longer be usable, so the shooting elements must be re-measured. , slowing down the shooting speed."

"Xiyi has developed a rapid-fire gun, which doubles the rate of fire. Our Qing Dynasty is a kingdom of heaven, how can we follow in Xiyi's footsteps!"

Speaking of this, Luo Chaoying pulled out his chest and said: "We are going to develop a brand new artillery, a forward artillery!"
