Abstract:
A propeller comprising:a) a hub having an axis of rotation; b) a plurality of blades connected to the hub and extending generally radially outwardly therefrom, each blade having a leading edge, a trailing edge, each blade defining a blade pitch between the leading edge and the trailing edge at a given radius from the axis of rotation; c) at least one reverse thrust member connected to at least one blade of the propeller, said reverse thrust member having a proximal edge, a spaced distal edge, and projecting forward from at least a portion of the leading edge of the at least one blade, said proximal edge being connected to the at least a portion of the leading edge of the blade, wherein each reverse thrust member has a decreasing pitch from the distal edge toward the proximal edge of the reverse thrust member at the given radius.
