A swashplate guide for use with a spherical bearing and which connects with an adjacent component includes a hollow cylindrical tube formed from a composite material. An exterior surface of the hollow cylindrical tube provides an engagement surface with the spherical bearing. A flange arranged at an end of the hollow cylindrical tube provides an interface with the adjacent component.

Composite swashplate guide for rotorcraft control systems

A linkage assembly configured for use on a rotor blade having a first section and a second section, the second section being configured to rotate about a blade fold axis between an aligned position and a rotated position relative to the first section is provided. The linkage assembly includes a bracket having a first portion rotatably coupled to the first section about the blade fold axis and a second portion mounted to the second section. A spacer assembly is positioned between the bracket and an adjacent wall of the second section. The overall thickness of the spacer assembly is adjustable to control a distance between the second section and the bracket to adjust the rotated position.

System for shimming blade fold angle about an axis of rotation

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.
