WebRailgun is an electrically-powered gun that accelerates a conductive projectile along magnetic metal rails. Various factors increase the projectile velocity. Each method has its … WebThe authors present a calculation in a simplified geometry for the current distribution in the rails of a railgun, taking into account the motion of the armature and the time variation of the current. Closed-form, asymptotic results for the current density are obtained for arbitrary time-dependent currents and velocities, in the limit in which the length scale k/sub 0//sup …
