Abstract (en)
A retention system retains a turbine blade dovetail in a retention ring dovetail slot. The retention system includes a retention opening (20, 30) formed in the blade dovetail (16). A through hole (22) is formed in the retention ring (14), wherein the through hole is positioned such that it is aligned with the retention opening when the dovetail is assembled in the dovetail slot (18). A connector (24) is disposed in the through hole and engages the retention opening. In this manner, undesirable relative movement of parts can be reduced or eliminated, thereby preventing excessive wear.
