Abstract
A cooled turbine shroud assembly includes a first cooling path and a second cooling path adapted to provide shroud impingement air at different pressures to enhance efficiency. The cooling air is preferably acquired from a common source of secondary air. In one aspect the assembly, a shroud support supports a shroud ring and the cooling paths are separated in part by a flexible seal.
