Abstract
A rail gun for accelerating a projectile therein includes a hollow insulating body forming a gun tube; and two rail assemblies supported in the gun tube and together defining an acceleration channel to accommodate a projectile for being propelled therein by a plasma armature generated by a high intensity current flowing through the rail assemblies and an electric arc connecting the rail assemblies. At least one of the rail assemblies includes a layer of an electrically conducting metal wool mass extending along and bounding the acceleration channel and an insulating substance held in the metal wool mass.
