ABSTRACT:
An ion drive system for creating a propulsion force or thrust has at least one stage having an emitter and an attractor spaced from the emitter by a gap. An ionizable dielectric media is located within the gap. The drive system further has a propellant source for introducing a propellant in the vicinity of the emitter and a power source for creating a high intensity field in the vicinity of the emitter to ionize the dielectric media and a diffused field in the vicinity of the attractor to accelerate the ions away from the emitter and thereby create a propulsive force. In a preferred embodiment, the ion drive system has a plurality of stages.
