THEORETICAL LIGHT-GAS GUN PERFORMANCE

Abstract

ONE-DIMENSIONAL, UNSTEADY FLOW THEORY OF AN IDEAL GAS IS REVIEWED AS IT APPLIES TO GUNS AND BALLISTIC MODEL LAUNCHERS. The method of characteristics is developed for the general case including chambrage and finite chamber volume. Results for helium as a propellant are given from which the required chamber size can be determined. The launch velocity for combinations of launch tube and chamber geometries is computed assuming no friction nor heat loss and an evacuated bore.
