ABSTRACT:
A system is shown for cooling and sealing gas turbine blade structures and discs. A coolant fluid of a required pressure enters an annular chamber radially outwardly of an annular array of stationary blades. The cooling fluid passes through these stationary blades into an inner annular chamber disposed radially inwardly of the stationary blades. The cooling fluid is permitted to leak out upstream between an upstream seal wall member of the inner annular chamber and a shoulder portion of an upstream rotor disc. The cooling fluid is also permitted to leak out downstream from the inner annular chamber between a downstream seal wall member of the inner annular chamber and a shoulder portion of a downstream rotor disc. The downstream wall member also contains angularly disposed passageways which direct jets of pressurized cooling fluid into ports on the adjacent downstream rotor disc. A portion of both the upstream and downstream wall members is a seal between their respective adjacent rotor discs and the stationary blades. The pressure within the annular chamber and leakage therefrom prevents hot motive fluid contamination therein and the resulting reduction in gas turbine cooling fluid efficiency.
