Abstract
An electromagnetic projectile launching system is provided with a pair of conductive projectile launching rails which are connected to a high current inductive power source. Current from an inductive energy storage coil is switched to the launcher rails to successively launch a series of projectiles. As each projectile is launched, the inductance of the coil is reduced to increase inductor current so that each successive projectile is launched at approximately the same muzzle velcoity.
