<p>To control disc temperature, provide blade tip clearance control, and purge the rotor bore of a high pressure compressor in a gas turbine engine, an axially elongated manifold is disposed coaxially in the rotor bore to distribute cooling air bleed from the compressor inlet airstream to selected cavities between successive rotor discs in amounts tailored to the particular cooling needs of the neighboring discs.</p> |
