Patent number: 9151162Abstract: 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.Type: GrantFiled: November 8, 2012Date of Patent: October 6, 2015Assignee: Bell Helicopter Textron Inc.Inventors: George M.

Patent number: 6439849Abstract: The present invention comprises an apparatus for mounting two or more tail rotor hubs to a tail rotor mast. The apparatus comprises a mast having an externally-splined inboard section shaped and sized to mate with an internal spline on an inboard trunnion. The inboard trunnion is mechanically fixed to the one or more outboard hubs via a torsionally-rigid connection. The outboard portion of the mast is designed to have reduced torsional stiffness, so that torque is transmitted to the outboard trunnions through the inboard trunnion rather than through the mast.Type: GrantFiled: May 3, 2001Date of Patent: August 27, 2002Assignee: Bell Helicopter Textron, Inc.Inventors: Ajay Sehgal, Glenn Shimek
