PROTECTIVE EDGE MEMBERS FOR COMPOSITE FLEXURES

摘要

The protective edge member (51, 53) for use on a composite flexure, such as a helicopter main rotor yoke (11), having an exposed edge surface (24), comprises an innermost composite ply (57) attached to the exposed edge surface (24), an outermost composite ply (59) attached to the innermost composite ply (57); and at least one interior composite ply (55) disposed between the innermost composite ply (57) and the outermost composite ply (59).
