ABSTRACT:
The invention is directed to a compressor that recirculates bleed air by way of a fluid distributing unit which is adapted to redirect and uniformly distribute the air bled through passages in a compressor shroud section across a cross-sectional area of a compressor's inlet region to provide uniform distribution of the bleed air into the compressor's impellar to thereby increase efficiency of the compressor.
