The Elastic Gimbal Rotor (EGR) is a new Sikorsky concept in helicopter rotor systems. The EGR uses essentially bearingless rotor blades attached to a rotor head which is able to tilt relative to the rotor shaft. The tilt motion about the gimbal bearing is restrained by an elastically deformable member of members which form part of the hub. This spring restraint action permits hub moments to be transferred from the rotor blades to the main rotor shaft. This program was a preliminary study of the elastic gimbal rotor. The emphais was on the dynamic loads and the aeroelastic response of the system.
