Abstract

Le plateau cyclique (2) sur rotor (1) utilise une partie cylindrique (3) du rotor pour se centrer par rapport à l'axe principal (8) de rotation. Plus compact, plus robuste, avec moins de pièces ce dispositif où la rotule-couronne (4) porte au centre un dispositif de rotation représenté ici par un roulement (5) et dont la partie interne porte un plan interne qui est manoeuvré en au moins trois points, forme l'ensemble du plateau cyclique (2) (rotule-couronne, roulement, et la partie interne), cette partie qui entraine l'ensemble du plateau cyclique est représenté ici par la couronne triangulaire, elle peut être déplacée dans le sens de l'axe du rotor, et également de telle sorte que son plan soit libre de mouvement angulaire par rapport à cet axe, et rend ainsi possible d'agir cycliquement sur l'angle du pas des pales par des liens entre la rotule couronne et les pieds de pale, toutes les manoeuvres des voilures tournantes sont assurées.
