Abstract : The design of a solid-propellant electrothermal-chemical (SPETC) gun includes a number of choices for propellant and electrical energy. The trade-offs inherent in the choices affect the maximum pressure and muzzle velocity as well as pulse power size. Three questions of interest are addressed theoretically in this paper: (1) Is the optimal web determined from a conventional, optimal, solid-propellant (SP) calculation altered by the addition of electrical energy? (2) Are there trade-offs between power and energy, and, hence, pulse power size, to attain equivalent performance? (3) Can grain progressivity and post-maximum-pressure (post-Pmax) plasma energy injection work together to optimize gun performance at higher loading densities?
