A propulsion system in which pure hydrazine is used as the fuel for both a bipropellant rocket engine for high-thrust performance and in multiple monopropellant thrusters for station keeping and attitude control functions. Use of a common fuel for both modes of operation significantly reduces propellant weight and inert propulsion system weight for any given mission requirements, and therefore increases the payload that can be delivered to and maintained in a desired orbit. Further, for station-keeping, the monopropellant thrusters can be augmented in pe...
A high-performance liquid fuel bipropellant high-thrust rocket engine, comprising: a fuel supply including a supply tank, fuel line and fuel supply valve; an oxidant supply including a supply tank, oxidant line and oxidant supply valve; a combustion chamber having an inlet for the fuel and oxidant connected to the fuel and oxidant lines; and means for minimizing unwanted combustions after shutdown of the engine by delaying closure of the fuel supply valve until after closure of the oxidant supply valve, to ensure that combustion is completed in the combu...
