Patent ID: 7452183

Claim:
A shroud assembly for a gas turbine engine having a temperature at a hot operating condition substantially greater than at a cold assembly condition thereof, said shroud assembly comprising: at least one arcuate shroud segment adapted to surround a row of rotating turbine blades, said shroud segment having an arcuate, axially extending mounting flange; and a shroud hanger having an arcuate, axially-extending hook disposed in mating relationship to said mounting flange; wherein the mating relationship is disposed at a medial location of said flange and said hook at the cold assembly condition, said mounting flange and said hook define a radial gap therebetween positioned circumferentially away from the mating relationship at the cold assembly condition, said shroud hanger and said shroud segment are subject to thermal expansion at said hot operating condition, and a dimension of one of said shroud segment and said shroud hanger are selected to produce a preselected dimensional relationship therebetween at said hot operating condition.
