摘要： A swashplate of a blade pitch control assembly is provided including a metal component having one or more interfacing features. The metal component includes a hollow first cylinder having a first flange extending outwardly from a first end thereof and a second flange extending outwardly from a second end thereof. A sidewall extends between the first and second flanges such that a cavity is defined between the first flange, the second flange, and the sidewall. A plurality of connecting members is connected to a portion of the first flange and the second flange and is spaced about a periphery of the first cylinder. A tubular composite component is arranged at least partially within the cavity between adjacent pairs of the connecting members.

摘要： A mounting assembly for connecting a first surface to a second surface and for holding a first servo which moves an adjacent first component is provided including a leg. A first end of the leg is attachable to the first surface and a second end of the leg is attachable to the second surface. The leg is generally bent such that the first end of each leg is arranged at an angle to the second end of each leg so as to transmit forces between the first and second surface. A bracket connected to the leg includes a notch configured to receive the first servo. When the first servo is positioned within the first notch, a free end of the first servo is operably coupled to the adjacent first component and the leg reacts forces generated by the first servo into the first and second surfaces.

摘要： An aircraft is provided and includes an airframe, a blade disk, which is rotatable relative to the airframe, including a plurality of rotor blades, a rotor shaft disposed to drive rotation of the blade disk relative to the airframe and a pitching of each of the rotor blades about corresponding pitch axes and a rotor assembly configured to form couplings by which each of the rotor blades is coupled to the rotor shaft. The rotor assembly includes a composite laminate arranged to resolve loading associated with the couplings in-plane of the composite laminate.
