摘要
A rotor yoke (10) for coupling helicopter blades to a rotatable support mast (12) utilizes a novel laminated construction. Layers (30) of unidirectional fibers and layers (32) of bias ply fibers are arranged in alternating sequence to form an elongate loop structure. At least some of the bias ply layers (32) extend between the sides of the loop to form a transverse central section (20). Further, at least some of the bias ply layers (32) include gaps to provide flexure areas (24) in the sides of the yoke (10).
