Abstract: A trunnion includes first and second portions. The first portion is capable of coupling directly to a drive tube of an aircraft, wherein the drive tube is capable of rotating around a first axis. The second portion is capable of coupling to a swash plate of the aircraft, wherein the swash plate is capable of causing the pitch of at least one of a plurality of aircraft blades to change. The first portion is operable to couple directly to the side surface of the cylindrical body of the drive tube without mounting to the top end or the bottom end of the drive tube. The trunnion is operable to simultaneously change the pitch of the plurality of aircraft blades by sliding along the first axis of the drive tube of the aircraft. The swashplate is operable to slide along the first axis of the drive tube with the trunnion.

Abstract: A rotating control system includes a member having at least one clevis defined by a pair of clevis arms disposed in a clevis plane, the at least one clevis having an axis of symmetry disposed in the clevis plane midway between the pair of clevis arms, a shaft member pivotally coupled between the pair of clevis arms, the shaft member having a shaft axis, the shaft axis disposed axially along the shaft member, and an anti-rotation device for limiting a rotation of the shaft member about the shaft axis, the anti-rotation device having a plurality of flanges configured to couple to the clevis arms of the member, the flanges extending from a surface of a base member, the anti-rotation device having at least one restraining member that protrudes toward the shaft member for limiting the axial rotation of the shaft member.
