Abstract:
A multi-ignition solid propellant gas generator comprising:A. a tank of reactive agent,B. an on-off valve connected to said tank for controlling time periods during which said reactive agent may exit said tank,C. a check valve connected to said on-off valve for preventing back flow such that said reactive agent may only flow from said tank through said check valve,D. a reactor connected to said check valve for decomposition of said reactive agent,E. an ignitor mounted into said reactor such that upon predetermined times said ignitor causes said reactive agent within said reactor to decompose into gas at a predetermined pressure and temperature,F. a pressure relief check valve with a preset cracking pressure operably connected to said reactor such that when the pressure in said reactor exceeds the cracking pressure of said pressure relief check valve gas flows from said reactor through said pressure relief valve,G. a gas generator connected to said pressure relief check valve such that gas vented from said pressure relief check valve enters into said gas generator,H. solid propellant placed within said gas generator which generates predetermined thrust when said gas from said reactor flows into said gas generator through said pressure relief check valve,I. an exhaust port operably connected to said gas generator for directing thrust in a predetermined direction, andJ. a dump valve operably connected to said exhaust port for quickly increasing the effective opening of said exhaust port such that a sudden decrease of the internal pressure of said gas generator adequate to extinguish said solid propellant.
