Abstract
A rotor control system operatively linked to a plurality of rotor blades includes a swashplate assembly having a stationary member and a rotating member. A blade attachment member is operatively connected to the plurality of rotor blades and a control horn is operatively connected to the blade attachment member and one of the plurality of rotor blades. At least one hydraulic actuator member is operatively coupled to the control horn and at least one hydraulic actuator element is operatively coupled to the swashplate assembly and the at least one hydraulic actuator member. The at least one hydraulic actuator member transmits control signals from the swashplate assembly to the one of the plurality of rotor blades through the at least one hydraulic actuator member.
