THEORETICAL STUDIES OF THE USE OF MULTIPROPELLANTS IN HIGH VELOCITY GUNS
Abstract
The use of propellant mixtures in high velocity guns, as means of increasing projectile muzzle velocity, is compared with the use of a single propellant. The propellant mixtures vary in chemical composition, web, and burning rate. A theoretical study is made using the M68 105mm high velocity tank gun as a test case. Gun geometry, projectile weight, and propellant shape are not changed from that of the standard gun. Interior ballistic trajectories in the parametric study are computed using a multipropellant interior ballistic digital computer code. Graphical methods are used to determine the optimum propellant mixture needed to maximize muzzle velocity at a given allowable maximum gun breech pressure. The effect of propellant grain shape on the performance of a gun is considered in a separate study. Results from the interior ballistic computer model are also compared with experimental results from the firing of propellant mixtures in the 5-inch and 16-inch guns used to launch high altitude atmospheric probes.
