A rotor system for a rotorcraft having at least one rotor blade pair operably associated with a differential pitch assembly operably for controlling a pitch angle of an upper rotor blade and the lower rotor blade in the rotor blade pair. Operation of the differential pitch assembly changes the pitch of the upper rotor blade more severely than the pitch of the lower rotor blade. As such, the rotor system is configured to provide optimum pitch of the upper and lower rotor blades during a helicopter mode and an airplane mode.
L'invention concerne un système de rotor pour giravion comprenant au moins une paire de pales de rotor associée de manière fonctionnelle à un ensemble de pas différentiel de manière fonctionnelle pour contrôler un angle de pas d'une pale de rotor supérieure et la pale de rotor inférieure dans la paire de pales de rotor. L'utilisation de l'ensemble de pas différentiel modifie le pas de la pale de rotor supérieure plus sévèrement que le pas de la pale de rotor inférieure. En tant que tel, le système de rotor est conçu pour offrir un pas optimal des pales de rotor supérieure et inférieure pendant un mode hélicoptère et un mode avion.
