Abstract:
A turbine shroud assembly includes an annular thermal shield around an annular shroud support. A honeycomb layer is attached to the shroud support along an inner side of the honeycomb layer and a heat shield is attached to an outer side of the honeycomb layer. The honeycomb layer may be brazed to the shroud support and the heat shield may be brazed to the honeycomb layer. A lip may depend inwardly from a forward end of the heat shield and an axial extension may extend beyond an aft end of the honeycomb layer. The thermal shield may be segmented. The shroud assembly may include axially spaced apart first and second stage thermal shields circumferentially disposed around an annular shroud support and may be incorporated in a high pressure turbine including first and second stage shrouds coupled to shroud hangers that are inwardly supported by hooks of the shroud support.
