<p>The fan blade retention device includes a retaining flange (18) located aft of the blade fixing means (7). The flange (18) abuts an outwardly facing circumferential groove (13) located between the flange (18) and the female half of the blade fixing means (7). The groove (13) is large enough to allow the blade fixing means (7) machining tool to be removed. The fan blade (28) includes an extension (21) of the blade root (11) on the aft side of the blade (28). When the blade root (11) is fully received within the female half of the blade fixing means (7), the blade extension (21) spans the width (20) of the groove and contacts the flange (18), thereby preventing the fan blade (28) from traveling aft. <IMAGE></p> |
