Demand Gas Generator Technology Program
Abstract
A 19-month technology program was performed to demonstrate the ability of a demand gas generator concept to vary mass flow at constant pressure and efficiently meet advanced post-boost propulsion system requirements. The program consisted of a parametric study and preliminary design of a demand gas generator for advanced post-boost propulsion applications, the characterization of a standard propellant and catalyst, the development of improved propellants and catalysts, the development of a pyrotechnic/overlay ignition system, the development of an electrical catalyst control system, and system demonstration in 12-inch diameter gas generator motors. Ten 12-inch diameter motor tests were conducted which demonstrated a throttling ratio as high as 38 to 1, a 430-second operation, a 28-pulse simulated post-boost propulsion duty cycle, and the capability of operation at three different pressure levels. All basic program objectives were achieved and the feasibility of the demand gas generator concept for post-boost propulsion application was demonstrated.
