Abstract
A tail assembly for a rotorcraft having a fuselage and a rotor assembly that generates first and second excitation frequencies. The tail assembly includes a stabilizer having an aft spar and a forward spar. An aft joint couples the aft spar to the fuselage and defines a pitch axis such that the aft joint allows the stabilizer to pivot about the pitch axis. A forward joint couples the forward spar to the fuselage. The forward joint has an axial stiffness configured to tailor a chordwise pivot mode of the stabilizer and a bending stiffness configured to tailor a beamwise bending mode of the stabilizer. The chordwise pivot mode of the stabilizer is below the first excitation frequency, the beamwise bending mode of the stabilizer is above the second excitation frequency and the chordwise pivot mode of the stabilizer is decoupled from the beamwise bending mode of the stabilizer.
