Analysis of a Solid Propellant Gas Generator Using an Ammonium Perchlorate-Polybutadiene Composite Propellant.
Abstract
An analytical program has been carried out for the purpose of studying the fluid dynamic and chemical processes occurring in a Solid Propellant Gas Generator (SPGG) device. The purpose of the SPGG device was to produce chemical exhaust species suitable for operation as a laser. The propellant used in the SPGG was Ammonium Perchlorate (AP) in a Polybutadiene (PBAN) fuel matrix. The combustion flame process was considered to occur in three successive steps: AP decomposition, PBAN pyrolysis, and combustion of the AP decomposition products with the PBAN pyrolysis products. For this combustion process a gas phase finite rate chemical reaction model was derived. The combustion process occurring near the surface of the propellant was modeled in order to derive non-equilibrium. (Author)
