Abstract
In support of the U.S. Army's science and advanced technology objective in hypervelocity penetration mechanics, the Army Research Laboratory has been studying the terminal ballistics of conventional and non-conventional high-velocity kinetic energy projectiles against urban, light-armor and heavy-armor targets. The purpose is to identify and analyze both mechanisms and concepts to effectively defeat a range of targets with inert payloads using the elevated impact velocities available from future delivery systems. To this end, a series of experiments has been performed launching low-aspect-ratio aluminum and steel cylindrical projectiles, aluminum conical projectiles, and encased reactive material projectiles, with nominal masses between 200 and 240-gm, striking finite aluminum armor at nominal velocities of 2100 m/s to observe crater and spall formation and to determine the damage capacity of the debris.
