A railgun, a linear motor device that uses magnetic force to launch high-velocity projectiles, is a linear motor device. The projectiles are usually not explosive. Instead, they rely on speed, mass, and energy to travel long distances. They can travel at speeds of up to 200 miles per hour and could cause serious damage when they reach their targets. A railgun can be used in many different applications.
Hypersonic Projectile
The Hypersonic Projectile (HVP), is a new type projectile designed to improve the lethality and effectiveness of railguns. It is a projectile with high explosive and speed that uses advanced aerodynamics. This projectile was recently successfully tested at Dugway Proving Ground.
Magnetic field
The current that flows through a railgun creates a magnetic field. The current acts as an electromagnet and creates a magnetic field around each conductor, while traveling in the opposite direction on each rail. This creates the net magnetic field between each rail that is perpendicular and parallel to the plane defined in the axes.
Lorentz force
Lorentz force railguns use a strong current to launch a weaponized missile at a target. This current will accelerate projectiles as they move along rails that are oriented at right angles. The projectile will eventually reach the end of the rails and exit through the aperture. This will cause a circuit break.
Range
Railguns are useful for protecting against sea-based threats such as submarines and missiles. Its range can be up to 100 miles, and it can be used in several different missions. Unlike other conventional weapons, the railgun does not use high explosive to destroy targets; instead, its projectiles hit their targets at hypersonic speeds.
Rate of fire
You can measure the rate of fire for a railgun in rounds per minute. The energy of the bullets affects the fire rate of a railgun. High-energy ammunition can fire 10 rounds per minute while lower-energy cartridges can fire only 1 shot. Railguns' rate of fire are important factors in determining weapon effectiveness.
Cost
If you are looking to buy a railgun, the most important question is how much it will cost. The good news is that railguns are relatively affordable compared with laser guns. The railgun measures 20 pounds in weight, and comes with a tough case and a rechargeable battery. Unfortunately, the projectile doesn't have a high velocity so it can be difficult for enemies to hit when they are close.
