An example of a hub for a tail rotor includes a body configured to couple to a mast of a rotor system, a trunnion disposed within the body, first and second shafts disposed on opposite sides of the trunnion, first and second end plates secured to the body, and first and second end bearings, the first end bearing disposed between the first shaft and the first end plate and the second end bearing disposed between the second shaft and the second end plate.

A method for designing a flight vehicle includes determining a preferred aerodynamic shape of a structure of the vehicle; modifying the preferred aerodynamic shape based upon constraints; and determining, using aerodynamic computational fluid dynamics, limit loading conditions for the modified aerodynamic shape. A computer-implemented system for designing a flight vehicle includes at least one computer operable to determine a preferred aerodynamic shape of a structure of the vehicle; modify the preferred aerodynamic shape based upon constraints; and determine, using aerodynamic computational fluid dynamics, limit loading conditions for the modified aerodynamic shape. Software for designing a flight vehicle, embodied in a computer-readable medium, is operable to, when executed, determine a preferred aerodynamic shape of a structure of the vehicle; modify the preferred aerodynamic shape based upon constraints; and determine, using aerodynamic computational fluid dynamics, limit loading conditions for the modified aerodynamic shape.
