THERMALLY COMPLIANT TURBINE SHROUD MOUNTING ASSEMBLY

摘要

A shroud assembly (33) is provided for a gas turbine engine that has a temperature at a hot operating condition substantially greater than at a cold assembly condition thereof. The shroud assembly (33) includes: at least one arcuate shroud segment (32) adapted to surround a row of rotating turbine blades (24) which has an arcuate, axially extending mounting flange (54); a shroud hanger (34) having an arcuate, axially- extending hook disposed in mating relationship to the mounting flange (54); and an arcuate C- clip (56) having inner (58) and outer arms (60) overlapping the hook (44) and the mounting flange (54). The curvatures of the mounting flange (54) and the inner arm (58) of the C-clip (56) are selected so as to define a matched interface therebetween. Their curvatures are substantially greater that the curvature of the hook (44).
