Abstract: An improved helicopter rotor flexbeam (20) comprises a pair of generally parallel outwardly open, cross-sectionally C-shaped beams (25) of a geometry which defines therein a first inboard region (A) of enhanced out-of-plane flexibility and a second outboard region (B) of enhanced in-plane and torsional flexibility.

Abstract: A part spherical laminated elastomeric bearing has a non- circular latitudinal cross-section to accommodate high torque loads in elastomer bending rather than in shear. The spherical profile of the bearing accommodates tilt primarily in shear. Both inwardly and outwardly extending lobes, or spines, are disclosed. The spherical, lobed bearing is useful for a constant velocity joint especially in a helicopter gimbal rotor system.
