Open an aircraft carrier to fight against Japan

An expert said: "Since this Guard Thunder Cannon has no rifling, it will not rotate when it leaves the barrel. In this way, it will inevitably roll up in the air, and it will be difficult to hit the target!"

Lin Yuan said: "When a shell moves in the air, it is inevitably affected by resistance and lateral wind. According to the principle of force synthesis, these two forces can be combined into one force. We call the point of action the center of pressure. This pressure It is impossible for the center to coincide with the center of mass, and this creates a moment, so the shell tumbles."

"But if we put the center of mass in front and the center of pressure in the back, the directions of the two forces will be opposite. When the shell moves in the air, under the action of these two moments, it will not roll over. We It is necessary to find a way to place the center of pressure at the back. The alternative is to increase the pressure at the tail. The specific method is: we use six pieces of steel to connect symmetrically to the tail of the shell, which increases the pressure at the tail. We call this thing the tail fin."

"As for the connection between the tail fin and the shell, we can make a tail pipe with a primer installed inside the tail pipe, the primer is connected to the propellant, and the tail fin is connected to the tail pipe."

An expert said: "My lord, we have never heard of what you said. I don't know if there will be any problems in manufacturing it?"

Lin Yuan smiled and said: "In fact, everyone has seen this principle. Everyone knows about bows and arrows. The feathers behind the arrows are actually used for this purpose. Regarding the tail fin, I will also provide you with the specific method of making it. You don't have to worry about it. .”

The expert said: "My lord, our ability to make steel is limited, and the shells consume a lot. After a battle is fought, why can't there be hundreds of shells?"

Lin Yuan smiled and said: "You don't have to worry about this, just use good steel for the barrel, and use the worst cast iron for the casing of the shell."

The experts looked at each other, Lin Yuan smiled and said: "This kind of gun has a low speed, so you don't need to use very good materials. There is another advantage of using cast iron. When it explodes, it can produce a lot of fragments, so that it can kill the enemy on a larger scale. .”

Lin Yuan added: "This type of shell also has low requirements for explosives. You can even use horse manure and fertilizer to make explosives."

After finishing speaking, Lin Yuan laughed a few times. At first he wanted to liven up the atmosphere, but he forgot that everyone has heard of horse manure, but this fertilizer was not widely known to the public until the 50s.

Lin Yuan quickly said: "The casing of this kind of shell is also very simple to manufacture. It can be cast directly with molten iron. The machining part only needs to process the necessary threads, so the manufacturing speed will be very fast."

At this time, an expert laughed and said, "My lord, this cannon has a name, but we also have to give the cannonball a name."

Lin Yuan thought for a while and said, "The sound of this kind of shell is very sharp, it sounds like a ghost roaring, so let's call it a ghost roaring bomb."

An expert laughed and said, "Your name is really good! It sounds enough to scare the old man to death!"

Lin Yuan quickly contacted the Beijing ship, and the Beijing ship quickly sent someone to send the technical information. After meeting Liu Hao, political commissar Han Mingguang kept an eye out and didn't let Liu Hao's ship go to Beijing, but left two He knew that Lin Yuan would definitely ask the Beijing ship to deliver things when he was in Beijing, and he really used it.

Lin Yuan looked at the technical information, and the officers and men on the Beijing ship were very careful. They basically replaced all the modern vocabulary, and changed the simplified characters into traditional characters. Lin Yuan handed over the materials to the experts, and then Call Fade Chen and ask him to train a group of shooters.As soon as these things were finished, someone came to report: "There is a man named Wang Datie, who claims to be Lord Lin's confidant, and is bringing dozens of people to make trouble in the barracks."

Upon hearing this, Lin Yuan quickly followed the reporter to the barracks.

On the playground of the barracks, two groups of people are confronting each other. One group is holding swords and spears, and the leader is Wang Datie; the other group is holding guns, and they are soldiers of the Qing army.

Lin Yuanyuan shouted angrily: "Put down the guns!"

When everyone saw Lin Yuan coming, they put down their weapons. Lin Yuan walked between the two groups and asked, "What's going on?"

Wang Datie was full of grievances, and said, "They won't shoot us."

Lin Yuan turned his head to look at the battalion officer who issued the ordnance, and asked, "Why didn't you send him the gun?"

The battalion officer was used to bullying others, and he was worried that Lin Yuan would turn to Wang Datie, but when he saw Lin Yuan asking calmly, he relaxed a little, and said helplessly, "There is nothing we can do? There are not enough guns in the first place." , of course it must be sent by veterans."

Excellent shooters are fed with bullets. This sentence is not false at all, but in the current situation, the supply of bullets is insufficient, and there are not so many bullets for novices to practice, so the guns have to be given priority to veterans. "

Wang Datie said angrily: "Why should you give them guns! What about their original guns! Throw the guns to the little devil when you run away, and take the guns if you still have the face."

A whistle chief stood out from the crowd. "Shao" was an organizational unit of the Qing army. There were about 80 people in a whistle. The back road has been copied by the little devil, why don't you retreat and wait for someone to make dumplings!"

Speaking of which, the whistle chief raised his right hand. There was no little finger on it, and there was only a dark red scar on the root of the finger. The whistle chief said: "See, who threw the gun away! My gun's fucking blasted, I'm lucky!" Well, just one finger is missing, I want to take the gun back to take revenge on the old man, and you, a recruit, dare to snatch the gun from me."

Someone in the crowd sneered "hehe" and said, "Aren't you possessed by gods? What kind of gun do you need?"

When everyone in Wang Datie heard this, their anger was instantly ignited, and they said angrily, "Who said that! Get out!"

When Lin Yuan saw it, he yelled sharply, "Shut up and stand aside."

Who dared not listen to Shangguan's words, the crowd parted, and Lin Yuan said to Wang Datie, "Come with me."

All the people on the field were Zhang Er's monks -- confused, not knowing what Lin Yuan was going to do when he called Wang Datie away. When he came to a place where no one was around, Lin Yuan said, "What do you think is the most important thing on the battlefield?"

Without even thinking about it, Wang Datie said, "Of course it's a gun. It turned out that the big brother told us that being possessed by a god made us invulnerable to swords and guns. Later we realized that it was all nonsense! If you have a gun, you are my father. If you don't have a gun, you are your grandson!"

Lin Yuan smiled "hehe" and said, "If you have a gun but no bullets, what is it?"

Wang Datie thought for a while and said, "That's even worse than my grandson!"

Lin Yuan nodded and said, "I've given you a very important job, which is much more important than killing the old man with a gun. Can you do it well?"

After hearing this, Wang Datie pulled out his chest vigorously, and said: "As long as it is told by you, Mr. Lin, I will definitely do it well!"

Lin Yuan said: "Okay! Then you will take your brothers to transport bullets to the battlefield, understand?"

Wang Datie patted his chest and said, "Make sure that every gun is full of bullets!"

Lin Yuan smiled and said: "That's good! You go back and persuade your brothers to be good."

Lin Yuan knew that the logistics supply of the Qing army was extremely poor, so he thought of setting up a special army for logistics supplies.

As soon as Wang Datie left, a herald hurried up to Lin Yuan and said, "Your Majesty tells you to go there quickly, there is an urgent military situation!"
