More Information
Summary:The blade lock (5), shaped to fix a turbine blade (13) in a disc groove (6), has a first side face (19) with a thrust surface that engages with the groove between the upper edge of a first lip (9) and the base of the groove as it is pivoted by a thrust element (3) between free and locked positions. The thrust element is in the form of a screw inserted in a threaded hole that made through the lock. The second side face (11) of the lock has a lug (15) that prevents any circumferential movement of the lock once it is in its locked position.
