ABSTRACT:
An improved seal cooling apparatus is provided for use in a gas turbine engine. In a particular embodiment, this apparatus includes means for deriving conditioning air from air discharged from the compressor diffuser and directing this air onto the seal stator to improve its thermal response. The apparatus also includes means to inject a portion of the conditioning air into a cavity forward of the seal to purge the region and prevent zero airflow conditions during engine operation for the purpose of discouraging overheating of a portion of the compressor rotor. A portion of the conditioning air from the cavity is subsequently directed to flow through and thereby cool the seal.
