Helicopter configuration for helicopters with rigid horizontal rotor

摘要

Helicopter (1) having - a hull (5), - a horizontal rotor (2) which is rotationally driven relative to the hull (5) about a vertical rotor axis (4), - a transverse to the longitudinal center plane (7) of the helicopter (1) the lateral boom (13) projecting away from the fuselage (5), wherein the lateral extension arm (13) is arranged asymmetrically on the side of the longitudinal center plane (7) of the helicopter (1) on which the horizontal rotor (2) in the forward flight of the helicopter (3) 1) runs back in order to generate in the forward flight of the helicopter (1) targeted lift on this side of the longitudinal center plane (7), - one at the free end (14) of the lateral arm (13) arranged vertical rotor (15), which is a horizontal Rotor axis (16) is rotationally driven, wherein the horizontal rotor axis (16) in a horizontal angular range of tangential to a circular arc around the vertical rotor axis (4) of the horizontal rotor (2) to parallel to the longitudinal center plane (7) of the helicopter (1) ausgei is chtet, and - an additional vertical rotor (21) which is rotationally driven about a in the longitudinal center plane (7) of the helicopter (1) extending further horizontal rotor axis (22) and below the horizontal rotor (2), characterized in that - a distance of the horizontal rotor axis (16) of the vertical rotor (15) from the longitudinal center plane (7) of the helicopter is at least as large as a difference between a radius of the vertical rotor (15) and a radius (8) of the horizontal rotor (2) and that the additional vertical rotor (21) is arranged in front of the vertical rotor axis (4) of the horizontal rotor (2).
