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
