Abstract
Dual propellant electrothermal propulsion systems with a polar propellant and a non-polar propellant are disclosed. Such a system may be used for imparting high specific impulse momentum on a spacecraft. A thruster includes a microwave source operably coupled to a heating chamber. An injector mixes polar and non-polar propellants and a nozzle at one end of the heating chamber. The thruster raises the temperature of the mixed propellants that exit the heating chamber to expand in the nozzle to generate thrust.
