A propulsion thruster (10) includes a solid-fuel, liquid-oxidizer main rocket engine (11), a tank (22) of liquid oxygen, and a turbine (32)-driven pump (30) for pumping liquid oxygen to the main engine. A solid-fuel, liquid-oxidizer auxiliary engine (40) has its oxidizer input port (50) coupled to the output (30b) of the turbopump, for generating drive fluids for the turbine (32) of the turbopump. The temperature of the turbine drive fluids is reduced to prevent damage to the turbine, and the mass flow rate is increased, by injecting water from a tank (6...
A propulsion engine, comprising: a solid-fuel main rocket engine including a first housing and a grain of solid fuel contained therein, and an inlet for oxidizer; a tank of liquid oxidizer; a turbine-driven pump including an oxidizer inlet port coupled to said tank of liquid oxidizer and an oxidizer outlet port coupled to said inlet of said first housing, and also including a turbine input port for accepting flow of turbine drive fluid, whereby the flow of said turbine drive fluid through said turbine causes a pumped flow of said oxidizer to said solid f...
