Continued Studies of Programmed-Splitting Stick Propellant
Abstract
A number of high-progressivity, high-density (HPD) propelling charge concepts are being investigated to provide significant improvement in muzzle velocity with minimal system impact. The particular approach presented in this paper is based on a concept which allows the charge designer to program a substantial increase in the burning surface at any desired time in the interior ballistic cycle, typically after peak pressure has occurred and the pressure is falling rapidly as the projectile moves downbore. Thus, a very high loading density charge can be employed without excessive burning surface leading to overpressurization early in the cycle or insufficient burning surface leading to incomplete consumption of the charge upon projectile exit. This concept, applicable to a number of propellant configurations, has been exploited first as programmed-splitting stick (PSS) propellant. Progress at the time of this writing is reported, including performance predictions, manufacturing experience, gun firings, and modeling efforts. Keywords: Gun propellant, High progressivity, High velocity, Guns, Efficiency, Stick propellant, Interior ballistics.
