Doomsday Bunker Upgrade Chapter 420: Electromagnetic Rifle

Making a gun is, in a sense, an easy task because there are only three really necessary parts to a gun, the chamber, the barrel, and the firing pin.

The chamber is used to hold and excite ammunition. In the era of front-loaded guns, the chamber needs to have sufficient air tightness to ensure that the kinetic energy generated when the gunpowder burns will not leak out due to poor sealing, affecting the range.

The barrel is used to stabilize the trajectory of the bullet, so that the walk after the bullet exits the muzzle does not become too scary.

And the bullet needs the firing pin to hit the flash cap at the bottom of the cartridge case, igniting the primer to ignite the gunpowder, so the firing pin is also an indispensable presence on a gun.

So simply put, if a gun has these three elements, it can be called a gun.

As for the accessories that supply ammunition, guide gas, aim, slow down recoil and many other functions, in a sense, they are not necessary, because the existence of these things is just more convenient for you to use the weapon in your hand That's it.

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, but also to make the muzzle more stable when firing continuously, allowing for more dense walks.

You need a feeding mechanism that can automatically feed ammunition, because when it comes to fighting, you can't shoot a bullet and load a bullet, which is too inefficient.

You need a good gas guide system, so that the gas after the gunpowder burns in the gun chamber can be discharged quickly and without disturbing your sight. Although most of the bullet gunpowder is smokeless gunpowder, these gases themselves have a certain temperature , If it is sprayed on the face, it is almost the same as directly facing the exhaust of the truck at close range, which is a thing that greatly affects the combat.

You also need a good aiming system to prevent all your hits from relying on faith...

So designing a gun, especially a good one, is really not easy.

Chen Xin was quite scratching his head about this. Although he had a lot of ready-made firearms and sci-fi weapons for reference, he still had no clue.

Laser or laser, of course, it can solve the problem of energy supply. This very common weapon in sci-fi works can already be launched, but the power is too small and it is not meaningful in actual combat. If the power is too large, it will not be worth the cost. , not as simple and cheap as traditional firearms.

If it's just traditional firearms, Chen Xin has no advantage in this aspect, and he is not as good as those firearms designers in the country. If he only designs traditional firearms, he can send the use requirements to the country's firearms designers and let them to design.

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

So Chen Xingeng prefers electromagnetic rifles.

In various sci-fi works, power armor with electromagnetic rifles is already a standard configuration. Not to mention, electromagnetic rifles themselves do not rely on the kinetic energy generated by the combustion of gunpowder like traditional firearms, so they can break through the power of traditional firearms and bullets. The upper limit is the initial velocity of 2000m/s.

And more importantly, the electromagnetic rifle relies on 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, and can also Reduce shell ejection time and increase launch speed.

Of course, for modern warfare, the power of the bullets during World War II was too much, so things like reduced reloading were developed. Naturally, the power of firearms and bullets does not need to be too large.

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

Otherwise, when you really need to face an enemy equipped with power armor, the weapon in your hand cannot penetrate the enemy's armor, which would be very embarrassing.

Although it is now possible to use heavy weapons to forcibly destroy power armor, heavy weapons are heavy weapons after all, they cannot be used casually, and they are not suitable for one hand.

So at this time, it is necessary to use an electromagnetic rifle that has sufficient power and many other advantages at the same time.

It's just that Chen Xin's difficulty now is how to design an electromagnetic rifle.

The relevant principle of the electromagnetic rifle is very simple, and even with a certain amount of hands-on ability, you can make something at home that can shoot projectiles out.

Simpler ones include coil type and orbital type, and more complex ones include reconnection type. It can be said that the technology is relatively mature, and even the Yan Kingdom military has begun to equip experimental electromagnetic guns and electromagnetic rifles.

In terms of form, the coil type is formed earlier, can fire heavier projectiles, and has a stable orbit and high shooting accuracy.

The orbital type has a high initial velocity, and the width of the two orbits can be adjusted. Not to mention the launch of various shapes of projectiles, but also because of the high initial velocity, the range can also be shot very far~IndoMTL.com~ But just For electromagnetic rifles, the coil type is more practical than the orbital type, because the orbital type consumes more electricity and consumes more energy. 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 came up with a version of the sniper rifle, which he planned to use for Qin Lan, just to match her power armor.

As for the electromagnetic rifle equipped for ordinary soldiers, Chen Xin still decided to use the coil type.

The production process is quite simple. After all, it is only the basic application of middle school physics knowledge. Under the premise that Chen Xin does not pursue to create something too awesome, it is OK to find a steel pipe and wrap a few laps of copper wire. 3D printing a shell.

The rest of the work can be handed over to the system upgrade. If you drop a survival point, you will naturally have a useful electromagnetic rifle.

In fact, that's exactly what happened. After the green light flashed, an electromagnetic rifle was already lying in front of Chen Xin.

The shape of this gun is borrowed from the C-14 electromagnetic rifle in the hands of the machine gunners in the StarCraft series. It adopts a bullpup design and drum feeding. A 40 cm long coiled barrel with a Picatinny rail at the top of the gun body can be installed with different sights.

Compared with the C-14 electromagnetic rifle, the gun in front of Chen Xin is relatively slender and not heavy. At least Chen Xin can easily pick up this gun without equipping power armor. And one-handed launch.

The gun body is powered by a high-performance battery installed under the barrel. One battery can support more than 2,000 continuous uninterrupted shots, and a drum can be loaded with 70 rounds, enough to support a high-intensity game. the battle is over.
