Abstract
La présente invention concerne un dispositif de variation de pas des pales pour un aéronef à voilure tournante (50) comportant un rotor principal (11) muni d'une pluralité de pales (12), chaque pale (12) comprenant au moins un volet (13) fixé sur le bord de fuite de la pale (12). L'inclinaison de chaque volet (13) est commandée, par l'intermédiaire d'un plateau cyclique. Ce dispositif prévoit que des vérins électriques, pilotés par un système de commandes de vol (54), sont montés en repère fixe et assurent le déplacement et l'inclinaison du plateau non tournant. Les vérins électriques assurent le contrôle du vol primaire ainsi que la commande multi-cyclique afin d'atténuer les bruits et les vibrations générées notamment par les pales (12) et le rotor (11).
