ABSTRACT:
A rotor system for a helicopter including a tension/torsion component which is fabricated from composite material and as a compound curved, continuous loop twin tension/torsion beam. Each end of the twin tension/torsion beam includes two curved (wrapped) ends which are oriented substantially orthogonally. At one end the curved ends extend about the flap hinge, and at the other end the curved ends extend about the fold and lead/lag hinge of the rotor system. To accommodate the twin tension/torsion beam at the flap hinge a support fitting is provided with lugs which are made compatible with the rotor hub lugs, and to accommodate the twin tension/torsion beam at the fold and lead/lag hinge a pitch varying structure is provided with twin beam engaging clevis surfaces.
