VTOL AIRCRAFT WITH LEADING EDGE TILTING DUCTED FANS

Abstract:

An exemplary ducted fan includes a circular duct surrounding a rotor hub from which blades radially extend, a stator having a stator leading edge and a stator trailing edge, and a stator chord line extending from the stator leading edge to the stator trailing edge, the stator chord line substantially equal to a duct radius from the rotor hub to an outer surface of the duct.
