Variable length compressor rotor pumping vanes |
摘要 |
<p>A compressor rotor (28) includes a rotor body mounting a disk (40) supporting an array of blades on a radially outer surface of the disk (40) in a primary flow path. A radially inner portion of the disk (40) is formed with an annular array of radially extending vanes (44) adapted to move cooling air flowing in a secondary flow path from a radially-inward direction to an axial direction (48) at a substantially center portion of said disk (40). Some of said radially-extending vanes (50) have relatively longer radial lengths and some of the radially extending vanes (52) having relatively shorter radial lengths to thereby provide a sufficient flow area while also lessening the formation of vortices along the vanes (44).</p> |
