Disclosed are embodiments of flow diverting lift elements which, when placed in the proper orientation and propelled through a fluid, produce a lift force with improved lift versus velocity performance. The flow diverting lift elements can produce lift for rotary lift devices such as aircraft. The flow diverting lift devices include an airfoil and a diversion wall extending from an upper surface of the airfoil. The airfoil can be an annular airfoil.
1. A rotary lift device, wherein the device comprises: a plurality of flow diverting lift elements each rotatable in a common direction by a motor, wherein the motor is mechanically coupled to each of the flow diverting lift elements, further wherein the flow diverting lift elements each comprises an annular airfoil comprising: an upper curved surface;a leading edge, wherein the leading edge extends along an inner perimeter of the annular airfoil; anda plurality of diversion walls on the upper curved surface of said annular airfoil, wherein each of the d...
