A variable-pitch multi-blade rotor for use as the anti-torque rear rotor of a rotating wing aircraft has a rotor with a central shaft rotated about a central axis, a hub constrained to rotate with the central shaft about the central axis, blades distributed around the central axis with each blade being connected to the central shaft by a twistable element, a pitch control disk for the blades which is constrained to rotate with the central shaft but free to slide axially relative to the central shaft, and a member for controlling the sliding of the pitch control disk along the central shaft. Each blade root is secured to a transverse thrust and pitch control lever forming a yoke having one end hinged to the hub and another end hinged to the pitch control disk.

A variable-pitch multi-blade rotor particularly intended for use as an anti-torque rear rotor of a rotating wing aircraft, the rotor being of the type comprising: a central shaft rotated about a central axis; a hub constrained to rotate with the central shaft about said central axis; blades distributed around said central axis and each connected to said central shaft by a twistable element; a pitch control disk for said blades, said disk being constrained to rotate with said central shaft but being free to slide axially relative thereto; and means for controlling the sliding of said pitch control disk along said central shaft; wherein the root of each blade is secured to a transverse thrust and pitch control lever forming a yoke having one end hinged to said hub and having another end hinged to said pitch control disk.
