摘要： A cross-beam helicopter rotor wherein the pitch actuator shaft passes through an elliptically shaped hole in the unidirectional, composite helicopter spar, each of selected dimension so that the stress concentration factor across the spar at the hole is minimized when the spar is carrying balanced centrifugal blade loads. The shaft also passes through a centering pin which is supported in the spar hole by an elliptically shaped plug of selected dimension so that when supported from the spar hole by elastomer of selected shape factor, durometer and dimension, the plug and pin are load isolated from the spar and the stress concentration factor across the spar at the hole is substantially unchanged from that of the unplugged hole both during balanced and unbalanced centrifugal blade load operation of the spar, and so that the elastomer transmits unbalanced centrifugal blade loads therethrough from the spar to the plug and pin for centering the rotor.

摘要： An articulated helicopter rotor with an improved blade-to-hub connection. An articulated helicopter rotor wherein the blade-to-hub connection consists of a spherical elastomeric bearing connected to the hub and a composite yoke connected thereto in series and consisting of a plurality of unidirectional high strength fibers bonded together to form a continuous strap which passes through a central opening in the elastomeric bearing and is pin-wrap connected to the hub at a single station and to the blade at two spaced stations so is to produce a construction which is light in weight, easy to manufacture, ballistically tolerant, redundant, and readily visually inspectable for structural integrity.

摘要： A part spherical laminated elastomeric bearing has a non- circular latitudinal cross-section to accommodate high torque loads in elastomer bending rather than in shear. The spherical profile of the bearing accommodates tilt primarily in shear. Both inwardly and outwardly extending lobes, or spines, are disclosed. The spherical, lobed bearing is useful for a constant velocity joint especially in a helicopter gimbal rotor system.
