Abstract:
An airfoil-rotor apparatus comprising:a first wing having a leading edge, a trailing edge and a plane of the first wing interposed between a top side and a bottom side of the first wing wherein, in the plane of the first wing, the first wing has at least one arcuate recess having a chord co-linear with the trailing edge of the first wing; and at least one rotor having a plurality blades, a center of planar rotation and an angle of planar rotation incline relative to the plane of the first wing wherein each of the plurality of blades has a pitch angle and a tip distal from the center of planar rotation and wherein the at least one rotor is positioned so that rotations of the plurality of blades about the center of planar rotation cause the rotor blade tips turning in an air flow to pass proximate to the at least one arcuate recess forward of the trailing edge of the first wing and wherein the center of planar rotation is aft of the chord co-linear with the trailing edge of the first wing.
