A ducted fan 20 provides lift to a flying vehicle 10. The ducted fan includes direction control vanes (1, 2, 3, 4) for controlling torques applied to the vehicle, and also includes lift negation vanes (305, 306, 307, 308), which control the available lift. The lift negation vanes are oriented with their longitudinal axes parallel to the forward-aft axis (9) of the vehicle in order to reduce drag at high forward velocities. The thrust negation vanes include fixed (305) and movable (305M) portions, with the movable portions rotatable so as to extend into t...


[ What is claimed is:] [1.] A vehicle adapted for flight, said vehicle comprising:a body defining a forward/aft axis;at least one shrouded fan mounted on said body, said shrouded fan including a circular shroud defining a duct, and a fan centered for rotation in said duct, said shrouded fan, when powered, providing lift to said body to aid in flight of said vehicle, said shrouded fan further including direction control vanes for redirecting airflow through said duct in a manner which provides a net thrust in at least one of forward/aft and left/right dir...
