<p>A propeller blade retention assembly (10) of the present invention for use with a propeller having a hub (12) rotatable about a propeller axis, is disclosed. The assembly includes a blade receiver (14) for mounting the blade to the hub and an internal surface (24) of a hub arm (22) for interfacing the receiver with the hub (12). The receiver (14) is positioned in the hub arm (22) and is non-integral with the blade and the hub arm internal surface (24). A retention mechanism (18) is used for retaining the blade receiver (14) to the hub arm (22) while allowing relative rotatable motion therebetween. A preload device (16) is provided for preloading the retention mechanism (18) prior to centrifugal loading during propeller blade operation. The blade is separable from the blade receiver (14) without disturbing the operability of the retention mechanism (18).</p> |
