Compatibility of Warm Gas Reaction Controls with Solid Propellant Exhaust Product Used on Ballistic Missiles 700780

A family of attitude controls has been developed using 2200 F gas from solid propellants to provide proportional reaction control thrusts of 13-125 lb, operating for durations from 1 to 10 minutes in a Pulse Duration Modulation (PDM) mode at 12-1/2 to 25 Hz with inlet pressures of 400 to 2800 psi. Operation in a solid propellant exhaust gas environment requires that condensable and particulate contaminants be accommodated without degrading performance. The exhaustive development program performed to successfully achieve contamination isolation is discussed.
