Chapter 421

In a sense, it is very easy to make a gun, because there are only three necessary parts for a gun: the barrel, the barrel and the firing pin.

The gun chamber is used to contain and excite ammunition. In the era of rifles, the gun chamber needs to have enough air tightness to ensure that the kinetic energy generated during the combustion of gunpowder will not leak out due to poor sealing, which will affect the range.

The barrel is used to stabilize the trajectory of the bullet, so that the walk after the bullet is shot out of the muzzle will not become very terrible.

The bullet also needs a firing pin to hit the cap at the bottom of the cartridge case, which stimulates the primer to ignite the gunpowder, so the firing pin is also an essential part of the gun.

Therefore, if a gun has these three elements, it can be called a gun.

As for the accessories with many other functions, such as ammunition feeding, air guiding, aiming and recoil slowing, they are not necessary in a sense, because the existence of these things is just more convenient for you to use the weapons in your hands.

But if you want to design a good gun, these functions are needed.

You need to slow down the recoil to stabilize the muzzle so that it doesn't go up. At the same time, you need to make the muzzle more stable during continuous firing, so that it can play more intensive walks.

You need an automatic ammunition feeding mechanism, because you can't load one bullet at a time when it's really fighting. That's too inefficient.

You need a good air guiding system to let the gas in the gun chamber after burning quickly and do not interfere with your sight. Although most of the bullet powder is smokeless powder, the gas itself has a certain temperature. If it is sprayed on the face, it is almost the same as directly facing the exhaust gas of the truck at close range, which is a very influential thing in combat.

You also need a good targeting system to avoid all your hits by faith

So it's not easy to design a gun, especially a good one.

Although Chen Xin has a lot of ready-made guns and sci-fi weapons as a reference, he still has no clue.

Laser or laser, of course, can solve the problem of energy supply. This kind of weapon, which is very common in science fiction works, can be launched. However, if the power is too small, it has little practical significance. If the power is too large, it is not as cheap as traditional guns.

If it's just traditional firearms, Chen Xin doesn't have any advantages in this respect, and he's not as good as the current firearms designers in the country. If he only designs traditional firearms, he can send the use requirements to the national firearms designers for them to design.

Even if a mature weapon needs a lot of time to design and modify in order to be finalized, it is not difficult to make simple modifications on the basis of existing weapons.

So Chen Xin is more interested in electromagnetic rifles.

Among all kinds of science fiction works, power armor with electromagnetic rifle is already a standard configuration. Not to say, electromagnetic rifle itself does not rely on the kinetic energy generated by gunpowder combustion as traditional guns, which can break through the upper limit of traditional guns' bullet power, that is, the muzzle speed of 2000ms.

What's more, the electromagnetic rifle relies on the electromagnetic force to push the ammunition, so the ammunition of the electromagnetic gun can only be the projectile itself, instead of the shell and charge, which greatly reduces the weight of the ammunition, reduces the shell throwing time, and improves the firing speed.

Of course, for modern wars, the power of bullets in World War II was too great, so we came up with such things as reducing the load of ammunition. Naturally, the power of guns and bullets was not too great.

But considering that it is equipped for power armor, naturally there is a necessary requirement that it can at least penetrate power armor.

Otherwise, when we really need to face the enemy who is equipped with power armor, the weapons in our hands can not penetrate the enemy's armor, which will be very embarrassing.

Although it can be said that heavy weapons can be used to forcibly destroy power armor, heavy weapons are heavy weapons after all, which can not be used casually and are not suitable for each person.

So at this time, it is necessary to use electromagnetic rifle, which has enough power and many other advantages.

But Chen Xin is now more difficult is how to design an electromagnetic rifle.

The relevant principle of electromagnetic rifle is very simple, and even has certain hands-on ability to make a thing at home that can shoot bullets.

It can be said that the technology is relatively mature, and even the military of Yan state has begun to equip experimental electromagnetic guns and rifles.

As far as the form is concerned, the coil type is formed earlier, which can launch heavier projectiles with stable orbit and high shooting accuracy.

The orbital type has a high initial velocity, and can adjust the width of two orbits to launch various shapes of projectiles. Not to mention, because of the high initial velocity, the range can also be very long.

But as far as the electromagnetic rifle is concerned, the coil type is more practical than the track type, because the track type consumes more electric energy and higher consumption. As a single soldier weapon, it is not very practical.

However, Chen Xin did not abandon the design of the Orbital Electromagnetic rifle. Instead, after making some modifications, he made a version of the sniper rifle. He planned to make one for Qin LAN, just to match her power armor.As for the electromagnetic rifle equipped for ordinary soldiers, Chen Xin decided to use the coil type.

The production process is quite simple. After all, it's only the basic application of physics knowledge in middle school. On the premise that Chen Xin doesn't pursue to create too powerful things, it's OK to find a steel pipe and wind a few circles of copper wire. At most, he can use 3D printing to make a shell.

The rest of the work can be handed over to the system upgrade to deal with, a survival hit down, there will be a good electromagnetic rifle out.

In fact, just like this, after the green light flashed, an electromagnetic rifle had been lying in front of Chen Xin.

The model of this gun is based on the C-14 electromagnetic rifle of the machine gunners in the StarCraft series. It adopts the design of no butts and drum feeding. The bullet adopts the 7.62mm diameter pin cartridge. The barrel is a 40cm long coil barrel, and there is a picardini guide rail on the top of the barrel, which can be installed with different sighting devices.

Compared with the C-14 electromagnetic rifle, the gun in front of Chen Xin is much thinner and lighter. At least Chen Xin can easily pick up the gun and launch it with one hand without power armor.

The gun body is also powered by a high-performance battery installed under the barrel. One battery can support more than 2000 continuous shots, while one drum can load 70 rounds, which is enough to support a high-intensity battle.
