Abstract
Electromagnetic launcher apparatus which includes a set of projectile rails and a set of switch rails both lying along a common longitudinal axis. An armature assembly includes at one end thereof a switching armature for conduction of current between the switching rails, and at the other end thereof a projectile armature for conduction of current between the projectile rails. The rail system is supplied with operating current and when a predetermined current level is obtained, the armature assembly separates such that the armatures are propelled in opposite directions. The rearwardly projected switch armature may be intercepted by a stop mechanism while the forwardly projected armature propels a payload such as a projectile.
