Method and apparatus for accelerating an axi-symetrical mass, such as a projectile, (50) by imploding a plasma discharge against the projectile surface, the plasma inducing an ionized liquid layer, and a magnetic field from the plasma interacting with the ionized liquid layer to accelerate the projectile. In a preferred embodiment the projectile is tapered toward its axis in a direction opposite from the direction of acceleration. To provide a long acceleration path a plurality of cascaded accelerating sections (51-55) are provided along the path and the projectile position, as it advances between the sections, is sensed and discharges are switched on sequentially in the sections. |
