Abstract
A rotor hub configured to support and rotate a plurality of rotor blades about an axis of rotation is includes a cylindrical body having a central shaft hole including the axis of rotation. The shaft hole has a radius extending from the axis of rotation radially. A plurality of radial spokes extends from the cylindrical body in a spoke direction. A plurality of arcuate segments extends between the distal ends of adjacent spokes to define a plurality of hub apertures. The spoke direction extends at an angle to the radial direction in both the horizontal plane, and a vertical plane, perpendicular to the horizontal plane. A line defined by the spoke direction does not intersect the axis of rotation. The spoke direction extends at an angle in the horizontal plane in a direction opposite to a direction of rotation of the rotor hub about the axis of rotation.
