Abstract
A turbine shroud includes a panel having a forward hook and an aft hook spaced therefrom. A primary cooling circuit extends through the panel adjacent the forward hook, and has a primary inlet for receiving primary air at a first pressure, and a primary outlet for discharging the primary air. A secondary cooling circuit extends through the panel adjacent the aft hook independently of the primary circuit. The secondary circuit includes a secondary inlet for receiving secondary air at a second pressure different than the first pressure, and a secondary outlet for discharging the secondary air. The dual cooled shroud accommodates differential gas pressure through the turbine.
