The work described in this report was undertaken to develop a gun using compressed helium as a propellant to fire a 17-grain fragment simulator at medium velocity range with small dispersion in velocity. The resultant helium gun has provided missile velocities ranging from 100 to 1700 fps with acceptably small velocity dispersion. This system has furnished a method of studying ballistic impact and penetration phenomena of single and composite polymeric materials and fabrics under closely controlled impact conditions.
