Abstract
The invention concerns an EM Launcher wherein each projectile has an insuor which, when subjected to a breakdown voltage, allows current conduction through the EM rails and the projectile for acceleration thereof. The insulator thus provides a disposable switch for a rapid fire EM launcher, negating the necessity of electrical (inductor circuit) charging or mechanical (breech) recycling. A key element in the invention is the replacing of a repetitively operated external switch with a plurality of single-shot, disposable switches. Better performance can be obtained from a single-shot switch (i.e., lower inductance, lower on-state voltage drop) because the compromises required of a repetitive switch to enable it to recover its voltage holdoff are not necessary.
