Iron backed, round bore, augmented electromagnetic accelerator as an injector

Abstract

An augmented electromagnetic accelerator apparatus which imparts an initialelocity to a projectile by use of enhanced inductance gradients and allows for the use of cylindrical projectiles by the use of a round bore, using a parallel gun rail geometry The enhanced inductance gradients are achieved by the use of an extra turn around the gun rails and enclosing the rail and the said augmented turn in laminated iron. The augmented accelerator has crossovers at the two ends (breech and muzzle end) which have minimum influences over the electromagnetics in the bore of the accelerator.
