A Two-Stage Light Gas Gun for the Study of High Speed Impact in Propellants
Abstract
This report describes a proposed two-stage light gas gun for the investigation of high speed impact in solid rocket propellants. Such a facility would provide valuable, quantitative information on the IM response of propellants for the ADF. A description of the operating principles and anticipated design is followed by a performance prediction using a numerical model. A quasi-one-dimensional computational fluid dynamics code was utilized to simulate the interaction of the gas dynamics with piston and projectile motion. Various projectile masses and initial gas fill pressures were investigated. It was concluded that the device described in this report was capable of accelerating masses of the order of 5- 15g at hypervelocity speeds using a helium driver gas and that performance would be enhanced by evacuating the launch tube prior to projectile release. Marginal performance increases could be obtained by replacing the driver gas with hydrogen.
