# What is a rail gun physics?

The underlying physics involved in the railgun are rather simple. Current flowing through an inductor creates a magnetic field. The current flowing through the field creates a Lorentz force on the inductor tending to push the coil apart.

## What principle does a railgun use?

How Does a Railgun Work? The basic principle behind a railgun is that it uses an electric current to create a magnetic field. This allows the railgun to shoot projectiles made from conductive materials. Electromagnetism is a well-known concept, but electromagnets can do a lot more than just stick to metallic objects.

## Is a railgun magnetic?

The concept of a railgun consists of propelling a conducting object along 2 conducting rails due to a magnetic force and an electric force.

## How do railguns use magnets?

In between the two parallel rails, both of the magnetic fields due to the rails points in the same direction and make a stronger magnetic field. This magnetic field then pushes on the projectile with the current running through it to propel it out of the railgun.

## Can a railgun shoot into space?

Railguns can acheive a muzzle velocity of a projectile on the order of 7.5 km/s. The Earth’s escape velocity is 11.2 km/s. It seems to me that a railgun style launch device built into a deep shaft such as an abandoned mine could reasonably launch a vehicle into space.

## How powerful is a railgun?

Projectiles launched via railgun can reach speeds of around 5,500 mph (8,800 km/h) whereas even the fastest bullets can only travel to around just 1,800 mph (2,900 km/h).

## How much damage can a railgun do?

The Rail Gun deals 500-550 damage to structures and can also pierce through a single structure without losing damage. Damage per second does not take into account charge up time.

## How much energy is needed to fire a railgun?

Powering a Railgun A good figure to start with is 25 megajoules. Since a joule is equivalent to one watt for one second, that means that for a railgun to shoot a projectile, it needs power equivalent to 25 megawatts for one second.

## What voltage does a railgun use?

Railguns typically operate above a thousand volts, generating huge currents for a few milliseconds to provide thousands of g’s of acceleration to a small projectile.

## Do railguns make noise?

“A lot of people think a railgun is not going to make a lot of noise,” Garnett says. “It’s electrically fired, and they expect a whoosh and no sound.” In reality, when the bullet emerges, it lets out a crack as electricity arcs through the air like lightning.

## Can you fire a bullet with electricity?

There are two approaches to electrically firing the cartridge. One method retains the primer, which functions analogously as a conventional primer. However, rather than being struck by a firing pin or by equivalent mechanical means, an electric current serves to detonate the primer.

## Who invented the railgun?

History. In 1918, French inventor Louis Octave Fauchon-Villeplee invented an electric cannon which is an early form of railgun. He filed for a US patent on 1 April 1919, which was issued in July 1922 as patent no. 1,421,435 “Electric Apparatus for Propelling Projectiles”.

## How fast is a railgun projectile?

Railguns use magnetic fields created by high electrical currents to accelerate a projectile to Mach 6, or 5,400 miles an hour. The velocity is sufficient to give the EMRG an effective range of 110 nautical miles, or 126 miles on land.

## How loud is a railgun?

Projectiles are guided to the target after leaving the launcher, and reach a target faster. At 100 yards, railguns sound no louder than a . 30-06 rifle firing. What little “smoke” they create is actually plasma particulates or dust.”

## How much armor can a railgun penetrate?

Using electromagnetic energy, the gun can fire a shell weighing 10kg at up to 5,400mph over 100 miles – with such force and accuracy it penetrates three concrete walls or six half-inch thick steel plates.

## Does a railgun have recoil?

Recoil forces in EM railguns appear wherever the breech of the railgun i s closed electromagnetically. This means recoil forces may appear on power supply leads, switches, or power supply components them- selves.

## Are mass drivers possible?

Earth-based mass drivers for propelling vehicles to orbit, such as the StarTram concept, would require considerable capital investment. The Earth’s relatively strong gravity and relatively thick atmosphere make the implementation of a practical solution difficult.

## Why are railguns so strong?

The railgun works by using extremely high electrical currents to generate magnetic fields capable of accelerating a projectile to speeds of up to Mach 6, more than twice as fast as existing projectiles.

## How many shots can a railgun shoot?

The goal, according to Tom Beutner, head of Naval Air Warfare and Weapons for the ONR, was ten shots per minute at 32 megajoules. A 32 megajoule railgun shot is equivalent to about 23,600,000 foot-pounds, so a single 32 MJ shot has the same muzzle energy as about 200,000 . 22 rounds being fired simultaneously.

## What makes a railgun so powerful?

A railgun works by generating a strong electromagnetic current that flows from one rail, through a U-shaped back end of the projectile, and into another parallel rail. This generates three magnetic fields—a parallel one around each of the rails, and a perpendicular one around the projectile.

## Why are railguns not used?

That’s because railguns use electricity instead of gunpowder, or jet or rocket engines, to accelerate a projectile at six or seven times the speed of sound. That creates enough kinetic energy to destroy targets. But there were a number of problems. Those included the range of about 110 miles in testing.

## Can railguns shoot through walls?

Railgun can be shoot through walls.

## How far can a railgun shoot accurately?

How far can a railgun shoot? A railgun’s effective range is closely related to the speed at which it can launch a projectile. Land or ship-based railguns with Mach 6 capabilities are understood to have effective ranges of roughly 126 miles (202.7 km) or 110 nautical miles (177.02 km) at sea.

## What is a railgun projectile made of?

The rails are made out of conductive metals (such as copper) which are fed with whopping amounts of energy from a generator — one side positive, the other negative — to propel the armature at great speed and distance via magnetic force.

## Are railguns lethal?

Though marketed as the first and “most powerful” handheld railgun ever, the GR-1 Anvil is not as lethal as you might think. However, its technical specs are still pretty impressive. It can fire 20 rounds per minute at full power and 100 rounds per minute at half power.
