ABSTRACT:
A bearingless rotor system has a flexible strap member to which the root of a rotor blade is attached, and a pitch rod aligned with the pitch axis and mounted to the rotor blade root and to a pitch arm, which arm transmits control system variations by way of a pitch link to the pitch rod. Tapered shoes are disposed adjacent the surfaces of the strap and are capable of applying a restoring force to the strap in opposition to flexural displacements of the strap member.
