ABSTRACT:
A turbine engine is constructed to passively modulate the flow of cooling air into the shroud. Sealing rings are disposed relative to the cooling air inlets in the shroud such that pressure and temperature variations in the engine will cause the cooling air inlets to be either fully opened, completely blocked by the sealing ring, or modulating therebetween in accordance with the cooling needs of the shroud.
