Abstract: Embodiments are directed to systems and methods for manufacturing composite assemblies comprising laying up composite plies on molds for two or more uncured components, joining the molds for the two or more uncured components to form a tubular body, and curing the joined components simultaneously to create a single composite assembly. The single composite assembly may form a spar for an aerodynamic component. The method may further comprise forming at least one axial edge having a sloped shape on the uncured components and mating the sloped axial edges together when joining the uncured components. The molds for the two or more uncured components may comprise female tools or both female tools and male tools. The two or more cured composite assemblies may comprise one or more of carbon and fiberglass composite materials.

Abstract: A rotorcraft includes a main rotor system coupled to a mast and a rotor assembly. The rotor assembly includes a yoke comprising a rotor coupling, a first damper mount attached to the rotor coupling, a rotor extension configured to couple to the rotor coupling and comprising a second damper mount, a damper coupled to the first and second damper mounts, and a fairing enclosing the damper and the yoke.
