摘要: This invention relates to the mounting of a servo hydraulic actuator for cyclic or collective pitch control of the rotor blades on a helicopter. The actuator is constructed with a cylinder barrel mounted on the frame of the helicopter with a coupling having bearing surfaces shaped to correspond to a portion of a sphere having its center substantially displaced from the coupling toward the pitch horn.
