Chapter 420: Electromagnetic rifle

In a sense, it is very easy to make a gun, because there are only three parts that are really necessary for a gun, the barrel, the barrel and the firing pin.
The barrel is used to contain and excite ammunition. If it is a front-loaded gun, the barrel needs to be airtight enough to ensure that the kinetic energy generated when the gunpowder burns will not leak out due to the lack of sealing, which affects the range.
The barrel is used to stabilize the trajectory of the bullet, so that the walking after the bullet is shot out of the muzzle will not become terrible.
The bullet needs a firing pin to hit the flash hider at the bottom of the cartridge case, and stimulate the primer to ignite the gunpowder, so the firing pin is also an indispensable presence in a gun.
So in simple terms, if a gun has these three elements, it can be called a gun.
As for the accessories for bomb feeding, air guiding, aiming, recoil slowing 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 useful gun, these functions are all needed.
You need to slow down the recoil to stabilize the muzzle so that it does not rise, and at the same time make the muzzle more stable during continuous firing, allowing for more dense walks.
You need a bomb feeding mechanism that can automatically feed bombs, because when you actually fight, you can't shoot one shot and load one bullet. That's too inefficient.
You need a good gas guiding system, so that the gas after the gunpowder burns in the barrel can be discharged quickly and without disturbing your sight. Although most of the current bullet gunpowder is smokeless gunpowder, the gas itself has a certain temperature. On the face, it is almost the same as facing the exhaust of a truck directly at close range. It is a matter that affects combat.
You also need a good aiming system to avoid all your hits relying on faith...
So designing a gun, especially a useful gun, is really not easy.
Chen Xin scratched his head quite a bit. Although he had a lot of ready-made firearms and science fiction weapons as a reference, he still had no clue.
Lasers or lasers, of course, can solve the problem of energy supply. This kind of weapon that is very common in science fiction 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 worthwhile, and it is not as good as the traditional Firearms are simple and cheap.
As far as traditional firearms are concerned, Chen Xin has no advantage in this respect, and he is not as good as the current firearms designers of the country. If he only designs traditional firearms, he can send the use requirements to the national firearms designers and let them design.
Even if a mature weapon requires a lot of time to design and modify before it can be finalized, it is not difficult to make simple modifications on the basis of existing weapons.
Therefore, Chen Xin prefers electromagnetic rifles.
In various sci-fi works, the power armor with electromagnetic rifle is already a standard configuration. Not to mention, the electromagnetic rifle itself does not rely on the kinetic energy emitted by the burning of gunpowder like traditional firearms, and it can break through the upper limit of the power of traditional firearms. The initial velocity is 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, and the shell and charge are no longer needed, which greatly reduces the weight of the ammunition and can also reduce the shell ejection. Time to increase the launch speed.
Of course, for modern warfare, the power of bullets during the Second World War was too high, so that something like reduced ammunition was developed. Naturally, the power of firearms and bullets was not too great.
But considering that this is equipped for power armor, naturally there is a necessary requirement, that is, it can at least penetrate power armor.
Otherwise, when it really happens that you 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, and it is impossible to use them casually, and they are not very suitable for human hands.
Therefore, at this time, it is necessary to use an electromagnetic rifle, which has sufficient power and many other advantages at the same time.
It's just that Chen Xin is now more difficult to design an electromagnetic rifle.
The related principle of the electromagnetic rifle is very simple, and even with a certain amount of hands-on ability, you can make something that can shoot out projectiles at home.
The simpler ones are the coil type and the orbital type, and the more complicated ones are the reconnection type. It can be said that the technology has been relatively mature, and even the Yan State 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 a stable orbit and higher shooting accuracy.
The orbital type has a very high initial velocity, and the width of the two tracks can be adjusted. Not to mention the launching of various shapes of projectiles, but also because of the high initial velocity, the range can also be hit very far~EbookFREE.me~ but only electromagnetic As far as rifles are concerned, the coil type is more practical than the track type, because the track type consumes more electricity and consumes more energy. As an individual weapon, it is not practical.
However, Chen Xin did not abandon the design of the rail-type electromagnetic rifle. Instead, after making some modifications, he came up with a version of the sniper rifle. He planned to make one for Qin Lan, just matching 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 is only the basic application of physics knowledge in middle school. Under the premise that Chen Xin does not pursue to create something too awesome, it is OK to find a steel pipe and wind a few turns 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 to deal with, and if the survival point is smashed, a useful electromagnetic rifle will naturally come out.
In fact, it was exactly the same. 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 used by the machine gunners in the StarCraft series. It uses a non-support design and a drum for bullets. The bullet uses a 7.62mm caliber nail bullet, and the barrel is a 40 cm. The long coil barrel, there is a Picatinny rail on the top of the gun body, you can install 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 being equipped with power armor and perform orders. Hand launch.
The gun body is powered by a high-performance battery installed under the barrel. A battery can support continuous uninterrupted shooting more than 2000 times, and a drum can load 70 rounds, which is enough to support a high-intensity battle. .
