A system for cooling hot section components of a gas turbine engine. The cooling system includes a plurality of compressors, or compression train, and an intercooler disposed between each adjacent pair of compressors so as to achieve the desired pressure and temperature of the cooling air at reduced shaft power requirements. The first stage of compression may be provided by the booster, or low pressure compressor, of the engine, with the first intercooler receiving all of the air discharging from the booster. After exiting the first intercooler, a first ...
[ What is claimed is:] [1.] A system for cooling at least a first portion of a gas turbine engine having a high pressure compressor and a core gas stream, said cooling system comprising:a plurality of compressors disposed in serial flow relationship with one another and effective for compressing air, each of said compressors having an inlet and an outlet, wherein said inlet of a first, upstream one of said compressors receives air having a pressure which is less than or equal to a pressure of the core gas stream at an entrance to the high pressure compre...
