IMPELLER BAFFLE WITH AIR CAVITY DESWIRLERS |
摘要 |
A gas turbine engine includes a high-pressure compressor (22) having an impeller (40) and an impeller baffle (50) having a generally annular body (52), the impeller baffle (50) spaced apart from a back face (42) of an impeller (40) to create an airspace therebetween, the airspace communicating between an impeller exit and an apparatus to be pressurized, the impeller baffle (50) including a plurality of generally radially-disposed ribs (56) extending into the airspace for diminishing the velocity of air swirling in the airspace.
