Connecting element and helicopter rotor incorporating same |
摘要 |
A connecting element having end regions (22, 23) joined by an intermediate by an intermediate region (26) is constructed of a plurality of fibre filaments extending longitudinally and continuously throughout its length. The fibers in the end regions are embedded in a thermo-setting resin matrix material and the fibres in the intermediate region are embedded in a resilient matrix material thereby permitting relative resilient torsional movement of the end regions about a longitudinal axis. Such a connecting element is particularly suited for use in a helicopter rotor and several embodiments are described and illustrated. In all embodiments the torsional flexibility of intermediate region (26) provides for blade feathering movements and in a preferred embodiment the inner end region (22) is constructed so as to be resiliently flexible in a blade flap plane and the outer end region (23) is constructed so as to be equally resiliently flexible in the blade flap and lead/lag planes.
