Plasma type armatures (railguns)

Railguns can easily exceed the muzzle velocity limit of conventional guns, however this requires the use of driving currents of over 1 million amperes. In the simplest railgun barrel configuration, the driving current flows in a loop formed by the projectile armature, the conducting rails and the power supply. The author looks at the plasma armature, the simplest type of armature to use, requiring only the generation of a plasma behind the projectile.<
