Rotor hub for a rotorcraft

摘要

A rotor hub (103) can include a yoke (211), a mast (201), and one or more radially oriented actuators (207a-207d). The first radial actuator and the second radial actuator each have a piston configured to impart a translation of the yoke (211) relative to the mast (201). The radial actuators (207a-207d) are configured to attenuate in-plane whirling vibrations. The rotor hub (103) can also have actuators (209a-209d) coupled between the mast (201) and the yoke (211) for attenuating flapping and vertical vibrations.
