Classification: CPC B | IPC B

Claim 7:
8. A system for controlling a pitch of each blade of a rotor, the system comprising:
a swashplate;
a pitch rod for each blade, each pitch rod coupling a rotating plate of the swashplate to an associated blade in a manner to achieve an inherent first pitch-cone coupling value and an inherent first pitch-flap coupling value;
an actuator for each pitch rod, each actuator being configured for altering a length or axial position of the associated pitch rod for controlling the pitch of the associated blade;
sensors configured for determining direction and magnitude of out-of-plane motion of at least one of the blades; and
a flight control system configured to receive signals from the sensors and for operating the actuators;
wherein the flight control system operates the actuators in response to the signals from the sensors to achieve at least one of a desired second pitch-cone coupling value or a desired second pitch-flap coupling value.
