Abstract
A thrust control valve which is operable to direct a gas supply to provide thrust is disclosed. The gas supply to obtained from a hot gas generator eg a rocket motor combustion chamber, and is directed through a nozzle by the operation of a plunger mounted within a pressure chamber. The pressure in the pressure chamber is controlled by the operation of a solenoid-operated poppet valve which moves between two positions to either pressurize the chamber ie sealing the nozzle with the plunger to provide no thrust, or to de-pressurize the chamber ie allowing gas from the gas supply to exit via the nozzle thereby providing thrust.
