ABSTRACT:
An improved centrifugal compressor for use in gas turbine engines includes a secondary air flow inlet in the compressor shroud at a location downstream of the inducer, with passive elements in the secondary air inlet for effectively preventing flow out of the secondary air inlet from the compressor impeller at part speed design operation, while augmenting and enhancing flow of secondary air flow into the compressor impeller at maximum design speed operation of the compressor impeller.
