AN ACCELERATED RESERVOIR LIGHT-GAS GUN

Abstract

Simple modifications in design and operation of a 0.22-caliber piston-compression light-gas gun resulted in an increase in muzzle velocity from 15,000 to 29,700 feet per second. A contracting tapered section was added at the high-pressure end of the pump tube. The forward 4 inches of the pump piston, made of high-density polyethylene plastic, is forced to intrude into the tapered coupling and launch tube during the launching sequence. Hydrogen has been substituted for helium as the working gas. The effect on performance of varying several importnat parameters is demonstrated. (Author)
