Abstract
A method and system for cooling a gas turbine engine in conjunction with an improved gas bearing face seal assembly. The gas turbine engine has a multi-stage compressor which discharges compressor discharge air for expansion by a combustor. A cavity which is aerodynamically linked to a turbine stage on its downstream end is formed by a metal structure the upstream end of which is connected to a seal which substantially inhibits the flow of compressor discharge air into the cavity. A conduit links an intermediate stage of the multi-stage compressor to the cavity for purposes of cooling the cavity and the turbine stage components located downstream of the cavity.
