Abstract
An integral propulsion and auxiliary power generation system includes a rocket engine, a liquid propellant supply system, an auxiliary electrical system, and a transmission system. The liquid propellant supply system is configured to supply a liquid fuel and a liquid oxidizer to the rocket engine. The liquid propellant supply system includes a gas generator configured to burn a mixture of the liquid fuel and the liquid oxidizer to generate a combustion gas stream, and a gas turbine configured to convert the kinetic energy of the combustion gas stream into mechanical energy. The auxiliary electrical system includes a power generator configured to convert mechanical energy into electrical energy and an electric load device electrically coupled to the power generator. The transmission system is configured to mechanically couple the gas turbine and the power generator to selectively transfer mechanical energy between the gas turbine and the power generator.
