Title:
VARIABLE LENGTH COMPRESSOR ROTOR PUMPING VANE
Document Type and Number:
Japanese Patent JP2013194738
Kind Code:
A
Abstract:
To provide a compressor rotor ring configuration which secures a desired flow area which excludes an excess pressure drop.
A compressor rotor includes a rotor body mounting a disk supporting an array of blades on a radially outer surface of the disk in a primary flow path. A radially inner portion of the disk is formed with an annular array of radially extending vanes adapted to move cooling air flowing in a secondary flow path from a radially outward direction to an axial direction at a substantially center portion of the disk. Some of the radially extending vanes have relatively longer radial lengths and some of the radially extending vanes have relatively shorter radial lengths.
