ABSTRACT:
A monopropellant propulsion system has a tank which includes a liquid chamber and a gas plenum. A monopropellant liquid is contained in the liquid chamber, and a monopropellant gas generator communicates with the gas plenum and the liquid chamber. The gas generator is operable to generate pressurized monopropellant gas in the gas plenum upon receiving monopropellant liquid from the liquid chamber. A one-way flow control valve controls flow of monopropellant liquid from the liquid chamber to the monopropellant gas generator. There is always a standing supply of pressurized monopropellant gas in the gas plenum such that a thrust chamber communicating with the gas plenum will always be supplied with gas. A thrust-generating mechanism is disposed in the thrust chamber in the form of an integrated valve and nozzle. The nozzle has a throat region communicating with the thrust chamber and the valve is mounted for movement relative to the nozzle for respectively opening and closing the throat region thereof upon actuation of the mechanism between its open and closed conditions to respectively produce thrust or block production of thrust.
