SYSTEM AND METHOD FOR COVERING A BLADE MOUNTING REGION OF TURBINE BLADES

摘要

A system includes a cover segment configured to mount in first and second grooves circumferentially along a blade mounting region of a turbine rotor. The cover segment includes a cover body and at least one fastener. The cover body includes first and second lips extending along first and second circumferential portions of the cover body at an offset from one another. The first lip is configured to mount circumferentially along the first groove and the second lip is configured to mount circumferentially along the second groove. The at least one fastener is configured to retain the cover body to the turbine rotor or at least one blade mounted in the blade mounting region.
