A rotor system for a rotorcraft, the rotor system is a rotor hub having six rotor blades attached to a rotor mast via a rotor yoke assembly. Each rotor blade is angularly spaced in 30 ° and 90 ° alternating angular increment about a mast axis of rotation. Such rotor blades spacing reduces the vibration that is translated into the rotorcraft through the rotor mast.

L'invention concerne un système de rotor pour un giravion, le système de rotor étant un moyeu de rotor comprenant six pales de rotor attachées à un mât de rotor par l'intermédiaire d'un ensemble de culasses de rotor. Chaque pale de rotor est espacée de manière angulaire selon une augmentation angulaire alternée de 30° et 90° autour d'un axe de rotation du mât. Cet espacement des pales de rotor réduit les vibrations qui sont transférées dans le giravion par le mât de rotor.
