An Examination of In-Bore Projectile Motion from an EM Railgun
Abstract
An investigation was undertaken to examine electromagnetic (EM) gun barrel/projectile interaction. The RASCAL code was used in this study because of its ability to easily manipulate relevant parameters such as gun tube centerline, projectile/bore contact stiffness, and projectile design geometry. This work centers around a comparison of projectile performance in the 9-MJ EM railgun at the University of Texas Center for Electromechanics (UTCEM) and a double-travel conventional gun. This comparison was made by varying the parameters listed above for two different projectile designs, one projectile being the M829 tank round, the other, a preliminary EM design. It was hoped that adoption of this format would identify specific areas of the EM gun/projectile system that excite transverse loading, with the results of the analysis presented here.
