Compliant Tail Structure for Rotorcraft

A rotorcraft comprising:

• a fuselage with an aft portion;
• at least one rotor assembly rotatably coupled to the fuselage and configured to provide at least vertical thrust;
• a tail assembly having first and second oppositely disposed tail members;
• and
• a tail joint connecting the tail assembly to the aft portion of the fuselage, the tail joint including at least four tail mounts configured to establish a nodding axis for the tail assembly;
• wherein, at least two of the tail mounts are resilient tail mounts;
• and
• wherein, the resilient mounts are configured to establish a nodding degree of freedom for the tail assembly relative to the fuselage about the nodding axis, thereby detuning dynamic fuselage responses from excitation frequencies generated by the rotating components.
