ABSTRACT:
Turbine cooling air regulation is obtained by directing cooling air through turbine cooling valve means to manifold means located internally of the roots of blades mounted on a turbine rotor disk. The manifold means has sealing engagement with the rotor disk and directs air from within, through passages to the interior of the blade where it passes through openings on the surface of the blade. The cooling system can include a plurality of turbine cooling valves which can be operated in unison, or independently actuated and scheduled.
