Abstract

An intercooled cooling system (100;200;300) for a gas turbine engine (20) is provided. The intercooled cooling system includes a plurality of cooling stages (110,115;210,215;310,315) in fluid communication with an air stream utilized for cooling. A first cooling stage (110;210;310) of the plurality of cooling stages is fluidly coupled to a bleed port (145) of a compressor of the gas turbine engine to receive and cool bleed air with the air stream to produce a cool bleed air. The intercooled cooling system also includes a pump (105) fluidly coupled to the first cooling stage (110;210;310) to receive the cool bleed air and increase a pressure of the cool bleed air to produce a pressurized cool bleed air. A second cooling stage (115;215;315) of the plurality of cooling stages is fluidly coupled to the pump (105) to receive and cool the pressurized cool bleed air to produce an intercooled cooling air, which is provided to the gas turbine engine (20).
