Disclosed is a single control thruster having the expanded capability of operating at various thrust levels and more than one propellant fluid so that the number of control thrusters for a maneuvering vehicle can be reduced to one third from that now required for appropriate maneuverability in space, resulting in large cost savings and improved reliability. Also disclosed is a “plug in”package with control thruster which can be removed from the vehicle and replaced to make the vehicle easily maintainable.
In a maneuvering vehicle, control thrusters for maneuvering the vehicle in space, each of said control thrusters having a catalytic chamber and a thrust outlet and further including, a valve housing with a plurality of pairs of series valves therein, and means for controlling said valves of said pairs wherein thrust material introduced into the catalytic chamber from the pairs of series valves is varied in type and amount, at least one of said types being an inert gas so that the control thruster will operate at different thrust levels.
