<p>The present invention comprises an apparatus for mounting two or more tail rotor hubs to a tail rotor mast (30) .The apparatus comprises a mast (30) having an externally-splined inboard section (96) shaped and sized to mate with an internal spline on an inboard trunnion (92) .The inboard trunnion (92) is mechanically fixed to the one or more outboard hubs via a torsionally-rigid connection (98) .The outboard portion of the mast (30) is designed to have reduced torsional stiffness, so that torque is transmitted to the outboard trunnions (90) through the inboard trunnion (92) rather than through the mast (30).</p> |
