Method for controlling temperature of a turbine engine compressor and compressor of a turbine engine

摘要

According to one aspect of the invention, a method for temperature control of a turbine engine compressor (200) includes directing a fluid from a first region (220) proximate a main flow path (218) in a downstream portion (214) of a structure (202,204) in a compressor (200) to an upstream portion (216) of the structure (202,204), wherein the fluid is cooled as the fluid flows through the upstream portion (216) of the structure (202,204). The method further includes directing the fluid from the upstream portion (216) of the structure downstream (202,204) to a second region (231) of the compressor (200) to cool the second region (231), wherein the fluid is directed through passages (221) in the upstream and downstream portions (214,216) of the structure (202,204) thereby substantially conserving an energy of the fluid within the structure (202,204) and wherein a pressure of the second region (231) is less than a pressure of the first region (220).
