Doomsday Bunker Upgrade

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

The chamber of the gun is used to contain and stimulate ammunition. If it is a front-loaded gun, the chamber needs to have enough air tightness to ensure that the kinetic energy generated when the gunpowder burns will not leak out due to the loose seal, affecting the range.

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

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

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

As for the accessories for feeding bombs, guiding gas, aiming, reducing 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.

But if you want to design a good gun, these functions are all 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 an ammunition feeding mechanism that can automatically feed ammunition, because when you really fight, you can't shoot a bullet and load a bullet, that's 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 current bullet gunpowder is smokeless gunpowder, these gases themselves have a certain temperature. To the face, it is almost the same as directly facing the exhaust of the truck at close range, which is a thing that affects the battle.

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

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

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

Lasers or lasers, of course, can solve the energy supply problem. This very common weapon in sci-fi works can already be launched, but if the power is too small, it is of little practical significance. If the power is too large, the cost will not be worth it. Firearms are simple and cheap.

As far as traditional firearms are concerned, Chen Xin has no advantage in this regard, and he is 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 country's firearms designers and let them 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 Xin is more interested in electromagnetic rifles.

In various sci-fi works, power armor with electromagnetic rifle is already a standard configuration. Not to mention, the electromagnetic rifle itself does not rely on the kinetic energy generated by the combustion of gunpowder like traditional firearms, so it can break through the upper limit of the power of traditional firearms, namely Muzzle velocity 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, without the need for the shell and charge, which greatly reduces the weight of the ammunition and can also reduce the shell ejection. time, increasing the launch speed.

Of course, for modern warfare, the power of bullets during World War II was too much, so something like a reduced-loading bullet was created. Naturally, the power of firearms 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, it would be very embarrassing to face an enemy equipped with power armor, and the weapon in his hand could not penetrate the enemy's armor.

Although it is said that heavy weapons can be used to forcibly destroy power armor, heavy weapons are heavy weapons after all, and it is impossible to use them casually, and it is not suitable for one hand.

Therefore, 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 is more difficult now is how to design an electromagnetic rifle.

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

The simpler ones are coil type and orbital type, and the more complex ones are 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 launch heavier projectiles, and has stable orbits 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.

However, as far as electromagnetic rifles are concerned, 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. At most, 3D printing is used. Make 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 supply. The bullet uses a 7.62mm caliber nail bullet, and the barrel is a 40 cm The long coiled barrel has a Picatinny rail on top of the frame for mounting different sights.

Compared with the C-14 electromagnetic rifle, the gun in front of Chen Xin is relatively slender, and the weight is not heavy. At least Chen Xin can easily pick up this gun without equipping power armor, and carry out a single shot. Hand firing.

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, which is enough to support a high-intensity battle. .
