摘要: A control system for a rotor assembly includes a plurality of sensors configured to detect a lead-lag rate of each rotor blade of a plurality of rotor blades rotatable around a shaft and a flight control computer configured to generate lead-lag compensation signals based on the detected lead rate and lag rate of each rotor blade to control each rotor blade.

摘要: A proprotor system (32a, 32b) operable for use on a tiltrotor aircraft (10) having a helicopter flight mode and an airplane flight mode. The proprotor system (32a, 32b) includes a rotor hub (102) and a plurality of proprotor blades (34) coupled to the rotor hub such that each proprotor blade has three independent degrees of freedom relative to the rotor hub including blade pitch about a pitch change axis (128), blade flap about a flapping axis (130) and lead-lag about a lead-lag axis (132). Each of a plurality of spherical bearings couples one of the proprotor blades (34) with the rotor hub (102) . In addition, each of a plurality of lead-lag dampers (134) couples one of the proprotor blades (34) with the rotor hub (102), wherein each lead-lag damper is aligned with the pitch change axis (128) of the respective proprotor blade, thereby providing pitch independent lead-lag damping.
