Claim 16:
17. An electrohydrodynamic (EHD) rotary system, comprising:
at least one rotary device configured to convert rotational motion thereof about an axis of rotation in a first direction into thrust, the at least one rotary device comprising a hub portion aligned with the axis of rotation, and at least one blade extending radially from the hub portion to a tip thereof, wherein the at least one blade comprises a front leading edge, a back-trailing edge and top and bottom surfaces that extend between the front and back edges;
at least one rotary electrode emitter, the at least one rotary electrode being electrically conductive and coupled to at least one blade of the at least one rotary device proximate to the back edge thereof;
at least one counter electrode, the at least one counter electrode being electrically conductive and positioned proximate to the at least one rotary device in a spaced relationship;
an electrical system comprising a voltage source including a first terminal that is electrically coupled to the at least one rotary electrode emitter and a second terminal that is electrically coupled to the at least one counter electrode, the voltage source comprising an electric potential difference between the first and second terminals that generates corona discharges from 4 the at least one rotary electrode that form flows of ionic wind emanating therefrom that rotate the at least one rotary device about the axis of rotation in the first direction; and
wherein the at least one rotary electrode emitter comprises at least one radially-extending electrically conductive member extending proximate to the back-trailing edge and at least one electrically conductive projection that extends away from the back-trailing edge of the at least blade in a direction extending from the front leading edge to the back-trailing edge, the at least one radially-extending electrically conductive member and the at least one electrically conductive projection being electrically coupled.
