Abstract (en)

[origin: WO9705017A1] In a helicopter (10) having a device for stabilizing yaw motion through the use of a tail rotor (2) with a plurality of rotor blades (11) extending radially from a hollow rotor shaft (15) which is mounted for rotation about a transverse rotor axis (14). The tail rotor (2) is provided with a device (22) for varying the thrust by a pilot input to the blades (11) of the tail rotor (2) and through the use of a gyro rotor (12) for automatic control of the tail rotor (2). The invention further comprises a three point mixing linkage (297) that permits the control of the tail rotor (2) through both the pilot inputs from (296) and the gyro rotor inputs (310).
