Abstract: A rotor hub comprises a gimbal assembly and an elastomeric centrifugal force bearing. The gimbal assembly is configured to transfer rotational movement of a mast to the rotor hub and to enable the rotor hub to flap relative to the mast. The elastomeric centrifugal force bearing is configured to withstand centrifugal force of a rotor blade when the mast is rotated and is configured to accommodate pitch changes of the rotor blade. A method comprises designing a gimbal assembly that enables a tail rotor hub to flap relative to a tail rotor mast. A centrifugal force bearing is selected that enables tail rotor blades to withstand centrifugal force and that allows for tail rotor blade pitch change articulation. Then, instructions are provided to use the gimbal assembly and the centrifugal force bearing in an in-plane tail rotor assembly.

Abstract: A hub system comprises at least one yoke, at least one shear bearing, and at least one mast adapter. The at least one mast adapter is configured to support the at least one yoke and the at least one shear bearing, and the at least one yoke has a flapping hinge that is non-coincident with a flapping hinge of the at least one shear bearing. Another hub system comprises a stacked yoke and a mast adapter. The mast adapter is configured to transfer rotation from a rotor mast to the hub system to rotate the hub system about a central axis of rotation. The mast adapter is further configured to support the stacked yoke such that each yoke in the stacked yoke is configured to accommodate at least some amount of rotation about an axis that is perpendicular to or about perpendicular to the central axis of rotation.

Abstract: Systems and methods of constructing a thermoplastic component include joining a thermoplastic skin to a thermoplastic core by introducing heat at an interface of each of the thermoplastic skin and the thermoplastic core to at least partially melt the thermoplastic skin to a thermoplastic core at the interfaces, applying pressure to at least one of the thermoplastic skin and the thermoplastic core to sandwich the elements, and cooling the interfaces below the melting point of each of the thermoplastic skin and the thermoplastic core to consolidate the thermoplastic skin and the thermoplastic core into a unitary thermoplastic component. An optional thermoplastic film may be disposed between the thermoplastic skin and the thermoplastic core. The thermoplastic skin may be joined to the thermoplastic core to form an intermediate thermoplastic component prior to joining the thermoplastic skin to the intermediate component.
