Abstract
A mechanical independent blade control (MIBC) mechanism for controlling the pitch of each of the blades of a rotor blade system or a main rotor of a rotor aircraft independently of the other blades includes a plurality of actuators disposed in the fuselage below the hub of the rotor, each being operable to selectively control the pitch of an associated one of the blades independently of the other blades, and a plurality of mechanical linkages disposed within the annulus of the rotor mast, each coupled between a blade and an actuator and operable to transmit a force output by the actuator to a pitch horn fixed to an inner end of the associated blade. The mechanism enables the direction of pitch of each blade to be changed more than twice during one revolution of the rotor.
