VARIABLE LENGTH COMPRESSOR ROTOR PUMPING VANES |
摘要 |
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-inward direction to an axial direction at a substantially center portion of said disk. Some of said radially-extending vanes have relatively longer radial lengths and some of the radially extending vanes having relatively shorter radial lengths to thereby provide a sufficient flow area while also lessening the formation of vortices along the vanes.
