A ducted fan for an aircraft or other vehicle includes aerodynamic features to selectably move the thrust vector of the ducted fan from the axis of rotation of the ducted fan, providing additional and redundant control authority to a control system. The control system may apply the aerodynamic features asymmetrically about the circumference of the duct and may apply the aerodynamic features differentially among a plurality of ducted fans. The aerodynamic features may include a morphing leading edge portion, an air dam, vanes and trailing edge control surfaces.
