Abstract:
1. A rotary-wing aircraft rotor with constant velocity drive, comprising: a rotor mast driven in rotation about a longitudinal axis; a hub connected to said mast by a constant velocity drive mechanism and by a tilting arrangement, the constant velocity drive mechanism having: wherein the tilting arrangement allows pivoting movement of the hub about a flapping axis converging with the axis of the mast and perpendicular to said axis of the mast in such a way that said hub is capable of being driven in constant velocity rotation by said mast about a geometrical axis of rotation of the hub which may be inclined in any direction about the axis of the mast; at least two blades, each linked to said hub by a coupling retaining and hinging the blade in pitch; and two driving devices configured to drive the hub and spaced from the differential mechanism along the axis of the mast.
