Open an aircraft carrier to fight against Japan

Lin was far away from Shanman's house at the beginning. As soon as he got home, he saw Guan'er running over in a hurry. She said, "My lord, something serious has happened. Go and have a look."

Lin Yuan had never seen Guan'er so panicked, and asked quickly, "What's wrong?"

Guan'er said: "When I was at Lafayette's place today, I heard from the eunuchs that the emperor was so angry today that he didn't even eat lunch, and even scolded several military ministers."

Lin Yuan thought: "The emperor is in a bad mood, what does it have to do with me." So he said: "The emperor is angry, what can I do?"

Guan'er quickly said: "Hey, my mouth is too stupid, I didn't understand it, the emperor is angry because of you!"

Lin Yuan asked in surprise: "Because of me, where did I offend him?"

Guan'er said: "I heard from those eunuchs that last night, Liu Kunyi, the governor of the Liangjiang River, made a report, which seemed to say that the ministers in the court were nepotism, especially the Tianjin Machinery Bureau. Said that you also arranged people in there, so the emperor was very angry, he has sent people to Tianjin Machinery Bureau, and he will severely punish those who are not paid!"

Lin Yuan thought to himself: "It's good to punish them. In this way, the output of Tianjin Machinery Bureau may be able to increase. The people I arrange in are not empty-handed! If they know Luo Chaoying's true level, they must confess him. Get up!"

Seeing Lin Yuan's relaxed expression, Guan'er couldn't help but said anxiously: "My lord, why are you not in a hurry? The emperor was very angry. He said that he thought you were a loyal and good minister of the Gan Kingdom, but who would have thought that you were also a treacherous minister... "

Lin Yuan interrupted her with a smile, and said, "It's okay, don't worry, I'll go to Tianjin Machinery Bureau to have a look."

When Lin Yuan arrived at the Tianjin Machinery Bureau, there were already many soldiers surrounding the machinery bureau, and an officer was standing at the door with his sword crossed.

That Su Mao's face was full of panic, but his heart was filled with joy. He knew that he was the one who provoked all of this. He begged the officer in a panic, and said, "My lord, what's the matter? Why are you here?" So many military masters?"

There was a majestic lion embroidered on the patch of the officer's official robe, which showed that he was a second-rank military officer, and he would not pay attention to a small chief engineer of the Machinery Bureau!So he ignored Su Mao, and watched those soldiers bring people out of the machine bureau one by one with a cold look.

Lin Yuan walked up to the officer and asked, "My lord, what should I call you?"

Seeing that it was Lin Yuan, the officer hurriedly got off his horse, and after paying respects, he said: "I am sent by the Holy Majesty to come to Tianjin Machinery Bureau to investigate those who have no skills but occupy high positions."

At this moment, a person who was brought out by the soldiers yelled angrily as he walked, "You dare to arrest me, do you know who I am?"

The soldier was annoyed by his quarrel, so he raised his waist knife and hit him hard on the back. The man was knocked unconscious by the blow. In this situation, they all shut their mouths.

The officer said with a smile to Lin Yuan: "Your Majesty must understand this matter thoroughly, so I won't be soft!"

Lin Yuan was a little worried about the old professor Luo Chaoying. After all, he was old, and he didn’t know if the old bones would be able to withstand such a toss. Lin Yuan then searched for Luo Chaoying’s shadow in the crowd, but he couldn’t find it after looking for a long time.

At this time, the officer said to Lin Yuan: "Master Lin, if the subordinates want to go in and search in person, I will not accompany you."

Lin Yuan also followed, and Su Mao followed behind. The group went to several places but did not see Luo Chaoying's shadow. When they walked to the east of the factory, they saw a yard from a distance.

The officer asked Su Mao, "What is that yard for?"

Su Mao replied: "My lord, it's the Artillery Design Department of our Machinery Bureau. Most of us imitate other people's artillery, and almost none of our own designs. That's why we put the design office in such a remote place."

The officer nodded, without asking what Lin Yuan meant, a few soldiers pushed open the gate, and everyone went in. As soon as they entered the yard, they heard a young man in the main room shouting loudly: "Old man, don't make trouble here, You go back and rest."

Then everyone heard the voice of an old man, the voice was full of helplessness, the old man said: "I have told you three times, you can't design the gun barrel like that, you can't assume that every moment the inner wall of the gun barrel The pressure is the same, and you have to consider the influence of the temperature of the propellant, so some places on the inner wall are under high pressure, and some places are under low pressure."

The young man smiled and said, "Old man, few people in the Qing Dynasty understand the design of this cannon, can you understand it?"

Hearing the old man's voice, Lin Yuan realized that it was Luo Chaoying, so he felt relieved. When they entered the house, Su Mao seemed to be reminding the officer, and said to Luo Chaoying, "Old Luo, why are you here?"

When the officer heard that this person was surnamed Luo, he glanced at the list in his hand, looked at Luo Chaoying and called out, "Luo Chaoying?"

Luo Chaoying is a leader in the field of gun design in China. Coupled with his advanced age, I am afraid that few people in China dare to call him by his name so rudely. Lin Yuan walked up to Luo Chaoying and said with a smile: "Luo Chaoying Old man, calm down..."

The officer shouted angrily: "Take it away!"

Just as Lin Yuan was about to stop him, the officer sneered and said to Lin Yuan: "Lin Yuan, the Holy Majesty knows that you have arranged idlers in the machine bureau, and Long Yan is furious. Your good days are coming to an end! I can't move you today, just wait , someone will come to settle accounts with you soon!"

Luo Chaoying was taken aback, then smiled and said, "You say I'm an idler?"

After finishing speaking, Luo Chaoying laughed a few times, walked up to Su Mao, and asked with a smile: "Do you know why the barrel you designed is not strong enough and has a low lifespan?"

Hearing these words, Su Mao felt as if struck by lightning, thinking: "How could he know these things?" Su Mao said: "It's not bad for us, the quality of the steel we can use is not good."

Luo Chaoying shook her head in disappointment, and said, "Don't pass the responsibility on to others if you can't do it yourself. Let me ask you, since the quality of steel is not good, why don't you use multi-layer barrel technology?"

The barrel of the artillery is often composed of several cylinders. The outer cylinder will give an initial stress to the inner layer, which can improve the strength of the inner barrel, like the coastal defense gun purchased from Germany in 1891. The barrel is composed of six layers of cylinders.

Su Mao said helplessly: "We can make multi-layer body tubes, but our technical level is limited, and it is too slow to do it."

Luo Chaoying asked again: "What about the tight tube?"

The tight-fitting tube refers to the steel wire or steel belt wrapped around the barrel of the gun. These steel wires or steel belts can provide an inward pressure on the barrel, which improves the strength of the barrel. In the Qing Dynasty, this Cannons produced by this process are also called wire-wound cannons.

Su Mao said: "We can't do this silk wrapping process, and the accuracy of using this kind of gun is often relatively poor."

Luo Chaoying said with a smile: "I have a way to solve your difficulties."
