Abstract
A gas turbine engine includes a high-pressure compressor having an impeller and an impeller baffle having a generally annular body, the impeller baffle spaced apart from a back face of an impeller to create an airspace therebetween, the airspace communicating between an impeller exit and an apparatus to be pressurized, the impeller baffle including a plurality of generally radially-disposed ribs extending into the airspace for diminishing the velocity of air swirling in the airspace.
