Abstract: According to one embodiment, a rotor system includes an anti-rotation sleeve featuring an outer recess portion and a tilt sleeve positioned about the anti-rotation sleeve and having an opening therethrough. A first swashplate ring is positioned about the tilt sleeve and features an inner recess portion. An anti-rotation mechanism is disposed through the opening and at least partially in the outer recess portion and the inner recess portion. The anti-rotation mechanism is operable to prevent the first swashplate ring from rotating about the anti-rotation sleeve. A second swashplate ring is positioned about the first swashplate ring and rotatable about the anti-rotation sleeve.

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.
