초록

A seal, and method of using same, for an inlet guide vane in a gas turbine engine includes a longitudinally extending tubular portion that has a longitudinal axis defined therethrough, a dovetail portion including a rib portion and a retaining feature. The rib portion is integral with the tubular portion and extends parallel to the axis, and the rib portion extends in a direction radially outward from the axis. The retaining feature is integral with the rib portion and tapers toward the axis.
