Gas turbine engine synchronizing ring bumper

摘要

A synchronizing assembly for a gas turbine engine includes a synchronizing ring. A composite bumper is secured to the synchronizing ring by a fastener. A structure is arranged between the bumper and the synchronizing ring. The fastener applies a first load through the structure to the synchronizing ring and a second load through the bumper. The second load is substantially less than the first load. In one example, the structure includes a bushing that extends through a hole in the bumper. The bushing is proud of the hole on the other side of the bumper and protrudes into the counterbore. The fastener is arranged in the bushing and applies a clamping load through the bushing to secure the bumper to the synchronizing ring.
