A railgun or rail gun, sometimes referred to as a rail cannon, is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high- velocity projectiles. The projectile normally does not contain explosives, instead relying on the projectile's high kinetic energy to inflict damage. [2] .

2023年6月5日 · As the name suggests, railguns fire their shots from rails, which are made of electricity-conducting metal. One carries a positive charge and one a negative. The power supply passes between...

2022年11月3日 · Rail guns use electrical power instead of chemical power to propel projectiles over long distances at hypersonic speeds. A linear motor device, this weapon typically uses electromagnetic force...

One solution is the electromagnetic rail gun, or rail gun for short. Using a magnetic field powered by electricity, a rail gun can accelerate a projectile up to 52,493 feet (16,000 meters) per second. And while current Navy guns have a maximum range of 12 miles, rail guns can hit a target 250 miles away in six minutes.

The Electro-Magnetic Laboratory Rail Gun is a long-range naval weapon that fires projectiles using electricity instead of chemical propellants. Magnetic fields created by high electrical currents accelerate a sliding metal conductor, or armature, between two rails to launch projectiles at 4,500 mph to 5,600 mph. Electricity generated by the ...

2014年8月12日 · A coilgun uses a series of electromagnetic coils to accelerate a ferromagnetic projectile. For the railgun, the projectile is accelerated because of a current running through the projectile.

A railgun is an electrical weapon that uses electromagnetic force to propel projectiles at high speeds, combining elements of electrical, mechanical, and materials engineering.

2023年11月1日 · An electromagnetic railgun can accelerate a projectile to astonishing speeds. Here's why Japan tested one on the JS Asuka.

2024年11月2日 · According to Chinese state-run media outlets, the People’s Liberation Army Navy (PLAN) tested an electromagnetic railgun by firing a smart bomb 15 km at a speed over Mach-5.0. Although the test...

2021年7月1日 · The U.S. Navy has pulled the plug, for now, on a futuristic weapon that fires projectiles at up to seven times the speed of sound using electricity.
