Abstract:
1. A control unit, which comprises: actuation units for a pilot in an aircraft, which comprises a rotating shaft mobile in rotation around an axis; said shaft is driven in rotation by an action of the pilot on the actuation units by mechanical transmission between said shaft and said actuation units; and a device for generating resistive torque structured to be fastened along the rotating axis of the control unit; characterized in that the device for generating resistive torque comprises: a friction disk, mounted axially and fastened to the rotating axle; a first annular track fastened to a frame element of the control unit; and a support structured to keep a first side of the friction disk pressed against the first annular track with a substantially constant pressing force exerted in a direction parallel to the axis of the rotating shaft and of the friction disk, wherein: the geometry of the friction disk comprises a flexible flange side and a tubular frame that links it to the shaft; and the torque generator device comprises an adjuster that adjusts the axial position of the friction disk on the axis.
