Abstract
A liquid-fueled rocket engine assembly comprises a combustor assembly, a combustor jacket for cooling the combustor assembly using pressurized liquid fuel exiting a fuel pump, a turbine for expanding gaseous fuel exiting the combustor jacket to power the fuel pump and/or an oxidizer pump, a flow control device for directing expanded gaseous fuel exiting the turbine through a first outlet and/or a second outlet, a discharge device for exhausting the expanded gaseous fuel exiting the first outlet, a heat exchanger for cooling the expanded gaseous fuel exiting the second outlet with some of the pressurized liquid fuel exiting the fuel pump, and a mixer for combining cooled fuel exiting the heat exchanger with liquid fuel to form mixed liquid fuel to be directed into the fuel pump. Another liquid-fueled rocket engine assembly and related methods are also described.
