A cooled turbine blade ring assembly surrounds an alternating arrangement of stator blades and rotating blades. A cooling air chamber directs cooling fluid to each stator vane retainer arrangement and to each ring segment which is circumferentially disposed about each rotor disc. The ring segments have a heat shield disposed on their outward side. The stator vane retainer arrangement including the ring segments and heat shields are maintained in a controlled temperature and in a controlled pressurized state. A bias producing means holds the heat shield and ring segments in a radially inwardly directed position, against the blade ring, to which it transfers reaction loads. The flow of cooling fluid maintains the heat shield and ring segments at a controlled temperature, while it prevents overcooling of the outer shroud portions of each vane. |
