This time I brought back a lot of equipment, including various machine tools, and naturally there are matching generators, and even a three-stage steam engine.
In the past, it was driven by a gasoline engine, which had to burn gasoline. It was not easy for the Eighth Route Army to obtain gasoline, but now, with a steam engine, it only needs to burn coal. There is no shortage of coal in Shanxi. , no coal, firewood will do.
Therefore, even at night, the base is brightly lit. Of course, this is only limited to indoors, and the light will not penetrate into the sky. As long as you guard the valley entrance on the other side of the sky, people outside will not be able to see anything.
With a generator, there is an electric light. You don't have to stay under the previous oil lamp, you just feel refreshed.
The brightness of the oil lamp is not high, so if you want to see more clearly, you have to get close to the oil lamp. When you get close, it will sting again and roast a strand of your hair. Now, with the electric light, under the light bulb I don't need to smoke from the oil lamp when I work, and I feel refreshed.
Qin Baoshan is just under the electric light, holding a ruler and compasses, and is drawing neatly, just like he used to build the Bayi-style horse rifle. To build a new type of rifle, it is inseparable from the standard blueprint. To act in accordance with the laws of science, we must not be sloppy.
Now, he not only needs to draw, but also occasionally calculates. After all, after using different bullets, the dimensions of many devices inside need to be modified accordingly.
"Come on, calculate these dimensions for me." Qin Baoshan said, handing over a piece of paper with formulas on it, and beside him, the sound of the crackling calculation board sounded.
"Okay." After counting these numbers, Wei Shuqin gave the result to Qin Baoshan, and this was the only thing she could do to help Qin Baoshan.
Three days to design and manufacture a brand new rifle, according to Qin Baoshan's words, it will be a cross-generational thing, which is impossible in anyone's mind.
However, Wei Shuqin believed in him, and believed that since Qin Baoshan said it, he would be able to do it, and now, as Qin Baoshan's design drawings were gradually released, she also saw the special features of this rifle.
Qin Baoshan said that it is brand new, and he is right, it is really brand new, and it is almost different from all the rifles now!
Although she is a woman, since Wei Shuqin wants to fight devils, she must be familiar with the weapons in her hand. Moreover, she must be familiar with all kinds of weapons, so that she can use whatever she can find on the battlefield.
Moreover, after coming to the military factory, although Wei Shuqin mainly does ideological work, since she wants to mingle with these workers, she must also be familiar with their work. Now, if there is a shortage of people on the production line, Wei Shuqin can also Go up to make up the number.
Therefore, she has seen and thought about most of the firearms. She is smart and learned a lot very quickly.
Now, the principle of this gun designed by Qin Baoshan is very special, I have never seen it before!
The bolt-action rifle that pulls the bolt and loads the bullet is destined to be backward. What Qin Baoshan wants to design is an automatic rifle. Since it is a continuous-fire rifle for automatic shooting, it must have a set of automatic shooting principles.
Now, with the release of the design drawings, the parts of the automatic machine of this firearm have also come out. It actually creatively uses the piston structure on it, which is completely different from before!
When it comes to common automatic shooting weapons, they are machine guns and submachine guns.
The commonly used method of machine guns is the recoil type. Specifically, the recoil force generated when the bullet is fired is used to make the barrel and bolt move backward together. This is called free travel. After retreating together for a while, the pressure of the gunpowder gas in the chamber has been reduced, and various mechanism actions, such as the separation of the bolt and the barrel to complete the unlocking, the bolt continues to complete the ejection, and the next re-entry is left to the recovery Spring in.
Although there may be some differences between light and heavy machine guns, they are similar, and they all use this principle of the back seat to achieve continuous firing.
What about the submachine gun?
The principle of the submachine gun is also similar. It uses the simplest automatic principle of the free bolt type. It is even simpler and does not even have a real locking mechanism. Can fire less powerful bullets, just in line with pistol bullets.
No matter how it is realized, it all uses the principle of the backseat, but the one designed by Qin Baoshan is not like this.
It's on the barrel, with little holes drilled! In this way, part of the gunpowder gas is drawn to push the bolt and other parts to move. This is simply a pioneering work!
At least, in the weapons used by the Eighth Route Army, I have not seen it yet.It was designed in the same way, so Qin Baoshan is definitely not bragging when he says it is cross-generational and brand new.
How did he think of it? It's amazing!
After calculating the data, she was fascinated by the design drawing. Qin Baoshan occasionally turned his head to look at her, smiled, continued to draw, and introduced at the same time: "The scheme I designed is called the air-guiding method. The brand-new Automaton scheme. Look here."
After finishing speaking, I introduced it with great interest: "In order to still be able to shoot after entering the dirt, I deliberately increased the gap here. After the firing, under the pressure of the gunpowder gas, the bottom of the shell is pressed, pushing the nose Move backwards, the gap is gone, the gun chamber is locked, and then, the gunpowder gas enters the gas guide device through the air guide hole, pushes the piston to move backward, the piston pushes the body, the body pushes the nose to rotate and unlock, and completes an automatic cycle. The reliability of the design scheme will be quite high, even if it enters the mud, just flick the barrel and it will fire."
What is the most talked about ak rifle? High reliability! During the Vietnam War, the American m16 rifle could not stand the harsh environment, so that the soldiers had to use a condom to cover the muzzle of the gun. What about the high accuracy? If you can't make a sound, everything is useless.
Our Eighth Route Army also needs a reliable weapon. As for the job of shooting the enemy at a long distance, we leave it to a special bolt-action rifle. Our gun can maintain a lethality of 300 meters!
"Then, why didn't the existing plan be used?" Wei Shuqin asked.
"Existing ones? Machine guns have too much recoil, and the bullets tend to fly randomly when used. Submachine guns have too little recoil, so they can't move at all. If you don't innovate, they won't work." Qin Baoshan said: "It's a pity. , it is not possible to apply for a patent this year.¡±
"What did you say?" Wei Shuqin didn't hear clearly.
Qin Baoshan was just mumbling just now, but now he smiled and changed the topic: "Come on, this set of data, with trigonometric functions, is it okay?" (Remember the website website: www.hlnovel.com
