摘要

The composite scissor assembly utilizes one or more flexible composite straps (21) disposed either in a radial or non-radial relationship between a hub attached to a rotor shaft (24) and an inner or outer ring (26) of a helicopter swashplate (20). The composite material has sufficient edge-wise stiffness to allow effective torque transmission between the rotor shaft (24) and the swashplate (20) yet has sufficient flexibility to allow for a vertical and angular displacement of the swashplate (20) relative to the rotor shaft (24). Utilizing a flexible composite scissor assembly eliminates the need for mechanical linkages having pins and bearings which are a frequent source for wear, increasing the reliability of the rotor assembly, while reducing weight.
