Su Mao hurriedly asked, "What good way do you have?" ”

Lin Yuan knew that Luo Chaoying was going to use the advanced technology of the 21st century, and he couldn't help but feel a little proud in his heart, but while he was proud, he suddenly thought that Shen Wanqing had said that the Japanese had bought an official in the Machinery Bureau, and the official's name was Lin Yuanzhi Dao, but he didn't know what he looked like, and he didn't know if he was in this group of people.

Lin Yuan hurriedly stepped forward and said, "Old Luo, we'll talk about this later." ”

The officer was already 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 on, tie up this old thing!" ”

That Su Mao didn't look at the usual submissive, looking like a small low, but at this time, like a crazy leopard, he roared at the officer: "Don't make any noise! ”

The officer couldn't imagine that he would be like this, and he didn't care about the following crimes that would be held accountable, so he was stunned on the spot, Su Mao turned his head and asked Luo Chaoying: "What good way do you have?" ”

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

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

After entering the house, Luo Chaoying said: "Whether it is a multi-layer body tube or a filament body tube, their essential principle is the same, that is, before the gunpowder in the body tube explodes, give the body tube an inward force in advance, so that when the gunpowder explodes, part of the pressure will be counteracted." ”

"If we can use other methods to give the body a force inward, then we can achieve the goal without multi-layer body tubes or winding wires outside the tubes.

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 to the tube, these high-pressure liquids will squeeze the inner wall of the tube, if we can look at the tube from a very microscopic perspective, then we can find that all parts of the tube will be deformed, the pressure value of these liquids is above the yield strength of steel, which means that the deformation of each part of the tube is plastic, and the plastic deformation produced by the inner layer and the outer layer of the tube is different. The outer tube will squeeze the inner tube, which is equivalent to giving the inner tube an inward force, so that we can achieve the purpose of increasing the strength of the gun tube. ”

Su Mao nodded again and again when he heard this, and said, "This is really a good idea!" ”

Luo Chaoying said: "The strength of such a body tube will be twice the strength of an ordinary single-layer body tube!" Moreover, there are many other benefits of the body tube after such treatment, for example, the life of the body tube will be greatly increased, and high-performance alloy steel can be saved. ”

Su Mao thought for a while and said: "This is just a basic principle, there must be some other problems in engineering applications, for example, how much pressure should be selected for this liquid, and how to design the device for adding liquid to the body tube, have you thought about these things?" ”

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

Luo Chaoying smiled and pointed to his head, saying, "Don't worry, it's all here." ”

Su Mao praised again and again and said, "Old Luo, you are really a master!" I've seen you today. He turned his head to Lin Yuan again and said, "Lord Lin, since Luo Lao has such a great ability, why didn't you say it earlier?" ”

Lin Yuan said embarrassedly: "Didn't our ancestors have a saying, if the water is clear, there will be no fish, and if people are observed, there will be no disciples, I just want to be the same as everyone." ”

Su Mao said: "The officer will be handed over to me to deal with." As he spoke, he turned around and wanted to go out.

Lin Yuan grabbed him and asked, "Do you have an official here, named Xu Bin?" ”

Su Mao said: "Of course there is, he is the leader of quality inspection, and all the products produced must pass through his hands, how do you know him?" ”

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

Su Mao nodded, turned around and walked out.

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

Luo Chaoying asked, "What?" Since he is a Japanese spy, why didn't he arrest him? ”

Lin Yuan said with a smile: "Don't be in a hurry to catch him first, there is no other use in keeping him, we will put on a play for him in a while, I will ask Su Mao to invite all the officials in the machine bureau, you give them a lecture, do you know what artillery is in Ludao, it was not studied in our time, you will bring it up at the meeting in a while, 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 a little difficult to develop this thing, but I don't understand it very well, because the principle of the laser cannon is completely different from the traditional artillery." ”

Lin Yuan said, "You can't say this! You think, the little devils don't even know what a laser is, if you want to talk about the development of a laser cannon, how can they believe it? If the gap in this technique is too big, they won't bother to study it, and if you think about it, is there one that you can see but can't touch? ”

Luo Chaoying said: "Well, I have a way. ”

At this moment, Su Mao walked in and said, "I have sent the officer and his men away. ”

Lin Yuan said: "Chief Engineer Su, it's better to be like this, let Luo Lao tell you about the relevant knowledge of artillery." ”

Su Mao said: "Great, I can't ask for it, there are too few people in the Machine Bureau who understand these things now." ”

Soon Su Mao gathered everyone together, Lin Yuan specially asked who Xu Bin was, Xu Bin was a middle-aged man, a little thin, the horse coat on his body was about to fade, holding a notebook and a pencil, first write the date on the notebook, and then sit there upright, waiting for the start, like a studious student.

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

"Today I want to discuss with you the issue of the rate of fire of the artillery, everyone knows that the rate of fire of this gun is very slow, for what? Because the barrel of the artillery is rigidly connected with the gun carriage, when a shell is fired, the barrel of the artillery must move backwards with the gun carriage, that is, recoil, so that if you recoil, the shooting elements that have been set up before cannot be used, so it is necessary to re-measure the shooting elements, which slows down the firing speed. ”

"Xiyi has developed a rapid-fire cannon, the rate of fire has doubled, our Qing Dynasty is the upper kingdom of the Celestial Empire, how can we follow in the footsteps of Xiyi!"

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