Abstract

A system for controlling solid propellant gas generators including a microcessor which has inputs such as the sensed temperature of the gases in the solid propellant gas generator, the pressure within the solid propellant gas generator and/or pre-programmed input control signals to the microprocessor for causing the microprocessor to produce signals that are used to control a modulation valve which in turn controls a thrust nozzle device that controls exhaust gases from the solid propellant gas generator.
