Abstract : An approximate method of analysis is formulated for gun internal ballistics. The method is incorporated in a digital computer program which is described. The validity of the method of analysis and computational procedure is substantiated by comparison of theoretical results with experimental ballistic data from an instrumented 105 mm M68 gun fired at Aberdeen Proving Ground, Maryland. Investigated gun performance includes breech pressures to 70,000 psia, muzzle velocities to 6300 fps, and maximum accelerations to 80,000 g's. (Author)
