ABSTRACT:
A method and apparatus for optimizing the radial clearance of rotor and stator vanes with their opposed structure for axial flow compressors of gas turbine power plants in which rotor disks are vented and thermally controlled by compressed air taken from the main flow path in the compressor via openings in the inner surface of the main flow path at one or more of the compressor stages. The removed air is supplied to annular spaces formed between rotor and/or seal support disks.
