ALTERNATOR DRIVEN ELECTROMAGNETIC LAUNCHING SYSTEM

Abstract

A superconducting single phase alternator is connected by a circuit breaker across the breech ends of a pair of conductive launching rails. At a predetermined point on the alternator voltage wave a projectile establishes a current path between the rails to initiate a transient, sinusoidal current pulse effective in accelerating the projectile along the rails. A switch is actuated in response to the projectile exiting the muzzle ends of the rails to impose a short circuit across the rails. The circuit breaker disconnects the alternator from the rails as the current pulse goes to zero. The system provides higher launcher efficiency and reduced muzzle flash with minimum barrel length penalty.
