ABSTRACT:
An invention is provided for a dual mode hybrid electric thruster propulsion system. The dual mode hybrid electric thruster provides low thrust using ion/plasma exhaust only, and high thrust by mixing a neutral molecular gas with the ion/plasma exhaust. The dual mode hybrid electric thruster includes a main propellant duct defining a main propellant intake. Coupled to the main propellant duct is an accelerating element, which includes an ionization chamber and an exhaust output. In addition, a momentum exchange zone is located at the exhaust output of the accelerating element. The momentum exchange zone includes a secondary propellant duct defining a secondary propellant intake, which provides a secondary propellant into the momentum exchange zone. In high-thrust mode, the momentum exchange zone exchanges momentum between high velocity ions from the accelerating element with atoms of the secondary propellant.
