Chapter 1518 The Road

Su You waved: "Come on, come on, you're just going to tell us about the structure and principles of the gun."

Zhao Xu also found it amazing: "Brother Chair, how did you do it?"

The train continued to move. Chen Wu took out two huge drawings from the drawing tube he carried with him and spread them on the table. He also took out a model of a brass machine part from his school bag: "This is the model of the core component of the gun."

After that, we went directly to the topic: "According to the requirements put forward by the Military Aircraft Department, the Ordnance Supervision and the School of Physics need to design guns that can automatically unlock, unshell, reload, and lock."

"This kind of thinking is called 'semi-automatic' by Jijiu."

"At the same time, new gun weapons are required, which need to be highly reliable, have high shooting accuracy, are easy to disassemble and clean, and are durable and effective."

"And it needs to be able to load more than five rounds, and the overall weight should not exceed eight kilograms."

"Look, Your Majesty, this is our final plan."

"The working principle of the machine gun is based on the Shenji gun. An air guide hole is opened under the barrel. After the hammer strikes the firing pin to fire the bullet, part of the gunpowder gas flows through the air guide hole at the bottom of the barrel near the end.

Enter a piston barrel and push the piston and machine frame backward. That's it."

After that, he picked up the brass gun model and simulated the movement trajectory of the gun parts after the bullet was fired.

"Your Majesty, you see, the guide protrusion on the bolt slides along the guide groove of the machine frame. When the machine frame recoils, it drives the two locking protrusions on the bolt to be released from the locking groove of the receiver and rotate to unlock."

"During the recoil process, the bolt will complete the action of ejecting the cartridge case and at the same time overwhelm the hammer into the cocking state."

Zhao Xu said: "I understand this, it is to use gas to complete the manual action of pulling the bolt and ejecting the shell!"

Chen Wu nodded: "Yes, next, the rear end of the bolt frame will hit the rear end surface of the receiver. At this time, the gunpowder gas has been completely released, and the recoil spring begins to drive the bolt back."

"Next, the machine frame guide groove will guide the guide protrusion on the bolt back, driving the bolt to rotate until the two locking protrusions enter the locking position."

"During this process, the bullet is loaded and the bolt is locked. Finally, the frame continues to return to position and the gun is ready to fire again."

Zhao Xu took the model and kept moving it back and forth. Because it was for demonstration, the spring was very weak, so he could easily complete the demonstration: "It's amazing! Brother Chair, this design is simply ingenious!"

Chen Wu said: "I have been to Dongshengzhou. There are many people there, but we Song people are too few. If the Shang and Zhou immigrants there refuse to accept enlightenment, we will be in great trouble."

"With the continuous gun, the new army only needs simple training, and one soldier can serve as three or even four soldiers."

Zhao Xu was very excited: "If the 50,000 soldiers of the Fourth Army in the capital are all changed, it will be equivalent to 50,000 being changed into 200,000. The only increase is ammunition supply!"

"If we equip the 35,000 people guarding Jiuyuan, we will have an army of 170,000 people there, and we will have an absolute advantage over the Liao Kingdom in Ningxia!"

This kid definitely secretly cares about the military!

Su You smiled and said: "Your Majesty, these are just theories. In fact, to control a huge territory, it is not enough to rely on a small number of elite soldiers. If rebellions continue one after another, even the most elite troops will be exhausted."

"Furthermore, the emergence of machine-guns will involve multiple subjects such as ammunition production capacity, installation sequence, new tactical synthesis, military reform, etc. It is not something that can be accomplished overnight."

"But one thing is certain, that is, we have completely widened the gap in military strength with the nomadic tribes, and have regained the huge advantage that we had during the early Han Dynasty a thousand years ago when 'one Han was against five barbarians'."

Chen Wu continued to introduce: "The rest are some small places. The ammunition supply method of this gun is also very unique. This is the magazine, which is made of steel. Look, loaded like this, it can accommodate a double row of eight bullets."

"This is the magazine model, and this is the receiver. The magazine can be pressed into the magazine from above..."

"Your Majesty, you see, when the last bullet is fired, it will become empty and idle. At this time..."

After saying that, he ejected the model bullet forward, and saw the bullet clip "ding" being ejected from the magazine into the air.

Zhao Xu was startled, then laughed, ran to pick up the magazine and said, "Let me play with it, let me play with it!"

Chen Wu said: "Here is the clip ejector. It can automatically eject the magazine when there is no ammunition, and will make a sound to remind the sergeant that it needs to be reloaded."

"Ding!" But it was Zhao Xu who played with the unclip function again and laughed again with joy.

Su You said: "Your Majesty, Chen Wu hasn't finished speaking yet."

"Oh." Zhao Xu became a good boy again: "Brother Chair, please continue."

Chen Wu said: "The total length of this gun is one meter. The sight adopts a flake front sight and aperture-type rear sight. It has an effective range of 700 meters and extremely high accuracy at a distance of 400 to 600 meters. It includes single shot, half clip, and full shot.

The clip has three loading methods, the total clip capacity is eight rounds, and the total weight of the gun is eight kilograms."

"Now we are improving the machine gun, such as adding sights, cheek pads and other special accessories to use it as a sniper gun."

"This is a new design drawing. Look, Your Majesty. The sight is installed to the left. It does not affect loading/ejection from above, nor does it hinder the use of mechanical sights."

"We have also made improvements to the shoulder area of ​​the gun holder, and carved out some space inside to accommodate tools for maintenance and disassembly and maintenance."

"According to the instruction of Master Wang from the Military Aircraft Department that the new army must dare to see red bayonets, the new drawings also designed bayonets to catch bamboo shoots."

The second-year boy in middle school was so excited that he couldn't find his way around: "How long until we get to Songyang Arsenal?"

Su You smiled and said: "The speed of the night train will be lower than that in the daytime. The speed is thirty miles per hour. There will be several stops in the middle. The distance from Zhongmou to Zhengzhou is one hundred and forty miles. Your Majesty can do the math yourself."

"Ah? Five more hours!"

There was another knock on the door, and the flat can came in, lit the gas lamp in the carriage, and then pushed a small dining car from the door: "Your Majesty, father, it's time to eat."

Su You said: "Eat and eat. Put the drawings away on the chair. Let's eat first."

The food on the train was actually not delicious, and Su You never thought of making any special provisions for Zhao Xu. Military management meant that everyone was the same.

The dish is very simple, canned beef meatballs, braised potatoes, fish-flavored shredded pork, rice steamed by train steam underneath, served in a military lunch box.

But Zhao Xu felt that this experience was really novel and rare. He took out the multi-purpose military knife from the small leather bag on his waist belt, opened the spoon, and ate it deliciously.

The flat can also used orange crystal powder to make a pot of orange water as a drink.

Zhao Xu devoured the meal, burped, then wiped his mouth, first poured a glass of orange water for Su You and the chair can, and finally poured a glass for himself and took a sip: "It tastes good!"

Su You held the lunch box in one hand and pointed at the cup with a spoon in the other hand: "This is what the soldiers are talking about. Citric acid is a by-product discovered during the development of penicillin. It can be produced in large quantities by inoculating Aspergillus niger with sugar cane molasses in the South China Sea and fermenting it.

"

"Add icing sugar, essence extracted from orange peels, and red and yellow pigments, and you get orange crystal powder."

"So this orange juice is prepared. It is not the same thing as what your Majesty drinks in the palace, and the freshly squeezed juices sold in the ice and snow shops in Bianjing City."

Who cares about this? Zhao Xu held the cup: "I just think it tastes better, better than freshly squeezed juice!"

Well, you are the emperor, so just drink it if you say it tastes good. This thing is unreasonable.

After dinner, I used the old habit, the flat pot and the chair to start reading and studying.

Zhao Xu felt embarrassed: "I have no homework today. For this trip, the mountain leader asked me to do it two days in advance."

Little sister, are you a devil? Su You complained silently in his heart, and then took out a box with black and white squares on the surface from under the desk: "Then let me play chess with Your Majesty."

Pour out the chess pieces inside, open the box 180 degrees, and turn it over to reveal the chessboard.

International chess is more popular with children than Chinese chess because the chess pieces are figurines.

However, Chinese queens are not as arrogant as foreign queens, so Su You followed Chinese customs and changed the queen to a prime minister, and the prime minister to a scholar.

The chess pieces on both sides are made of white copper and brass respectively, with magnets embedded underneath. The surface of the chessboard is made of iron, so the chess pieces can be held on it without fear of bumps.

The rules are simple, and the game is quite brain-burning. Fortunately, Su You is a bad chess player in any chess game, so he is not afraid that Zhao Xu will not win.
