A dual pressure solid propellant control system capable of operating at temperatures of approximately 3000° F. and at multiple pressures. A solid propellant gas generator is connected to a plurality of valve clusters by a manifold, the valves and manifold being of a high temperature material and each valve being independently operable. A pressure feedback loop maintains the system pressure at a commanded value by effectively increasing or decreasing the gas exit area by varying the pulse duration modulation of the valves.
1. A method for controlling the attitude and velocity of an aerospace platform having a post boost control system of the type including (1) a solid propellant gas generator for providing a hot gas output, the burn rate of said propellant being related directly to the pressure of said gas output so that the rate of said gas output is directly related to the gas pressure of said gas output, (2) valve clusters disposed symmetrically around the platform, each said valve cluster having a first high thrust nozzle oriented to produce thrust in a first direction...
