Abstract

Le rotor pour aéronefs à voilures tournantes, dans lequel les pales sont raccordées, sans articulation de traînée mais de façon non rigide, à chaque extrémité de deux longerons de support se croisant et qui sont résistants à la traction et à la flexion, selon l'invention est tel que tous les paliers 10, 12, 14, 16 prévus entre chaque longeron de support 6, 8 et la tête de rotor 4 sont réalisés sous forme de paliers permettant au longeron de support de se déplacer dans le sens axial. Les longerons de support sont en outre reliés entre eux de façon fixe, dans le sens axial, à leur point de croisement, par un dispositif de centrage 24 qui peut se déplacer librement dans le plan de rotation du rotor par rapport à la tête de rotor 4.
