Examination of a High-Explosive Round for a High-Aspect Ration Railgun Bore

Abstract: A railgun bore with a rectangular cross section is advantageous for launching a hypervelocity kinetic energy penetrator. An analysis is presented that supports the operation of a mass-stablized round with a high-explosive (HE) payload from the same bore. The design criteria and two bounding cases are provided to illustrate the effectiveness. Modifications to the bore insulators, ranging from 0 to 15 mm, can provide space for the projectile base diameter. The resultant HE round provides an increased capability, compared to conventionally launched HE rounds in velocity, armor penetration, and payload capacity.
