Abstract: A personal flight device includes a housing securable to the pilot. The device includes at least one pair of ducted fans, one fan of each pair mounted to each side of the housing. The axis of rotation of each fan is fixed relative to the housing. At least one engine is mounted on the housing for driving the fans and both fans rotate in the same direction for producing thrust. Three pairs of control surfaces, with one control surface of each pair is mounted below each fan of the one or each pair of fans.

Abstract: A personal flight device which includes a housing which is securable to a pilot having at least one pair of ducted fans, one fan of the at least one pair of ducted fans is mounted to one side of the housing, the other fan of the at least one pair of ducted fans mounted to the other side of the housing. Each fan rotates about an axis of rotation so as to draw air through the corresponding duct from an entry end of the duct to an exit end of the duct. At least one radiator is also provided. Each engine of the at least one engine is cooled by a radiator of the at least one radiator. Each radiator of the at least one radiator is associated with at least one passage having an entry end in communication with one surface of the radiator and an exit end adjacent the entry end of one duct of the ducted fans.
