<p>A hub mounted actuation system (20) for providing control of a portion of a rotor blade, on a rotorcraft. The rotor blade is attached to a rotor shaft (104) that rotates with respect to an airframe. The hub mounted actuation system includes a stationary support (106) mounted to the airframe and a rotary support (110) attached to the rotor shaft for concomitant rotation therewith. At least one hub actuator (112) rotates in combination with the rotor blade and includes a piston (114) which is slidable within a housing (116). The piston and housing define a pressure chamber within the actuator which contains a fluid to be pressurized. A displacement control device is disposed between the stationary support and the rotary support for controlling movement of the piston within the housing. A linkage (26) connects the hub actuator to the portion of the blade to be controlled. The linkage is adapted to displace the blade portion as a function of the movement of the piston within the housing.</p> |
