A Brief Investigation in the Improvements of Interior Ballistic Performance through the Control of the Surface Area of Solid Propellants

Abstract

This paper investigates the effect of optimizing the surface area of a propelling charge for the fictitious AGARD gun using a lumped-parameter, interior ballistics model. The results demonstrate that through just the control of the solid propellant surface area, the piezometric efficiency and muzzle velocity of the AGARD system are increased by 9.1 and 10.0 percent, respectively. Furthermore, the methodology used herein to develop an optimized charge design can be extended to legacy weapons to increase existing performance metrics. In doing so, the ballistic performance of various fielded weapon systems can be improved without the necessity of expensive system modifications/redesigns.
