Abstract
At least one exemplary embodiment is directed to a propulsion device that ionizes a portion of a medium and ExB drifts the ionized portion providing thrust where the ionized portion is created using high pressure field emitters comprising: a substrate layer; a gate layer; a field emitter tip; and a cover layer, wherein the field emitter tip is configured to emit electrons in a region when there is a potential difference between the gate layer and the field emitter tip, where the cover layer separates an ambient environment at a pressure from the region, and where a substantial portion of the electrons pass through the cover layer.
Claims11
A propulsion device comprising:
- at least a first charged fluid injector, wherein the first charged fluid injector is configured to inject a charged fluid into a plasma generation chamber including a medium, wherein the charged fluid provides free charges, wherein the free charges are energized, and wherein the energized free charges ionize at least a first portion of the medium;
- and
- a field generation device, wherein the field generation device is configured to generate an electric and magnetic field, and wherein the electric and magnetic fields have a ExB component, wherein the ExB component accelerates a portion of the first portion producing a thrust.
