ABSTRACT:
A system for cooling a turbine assembly in a gas turbine engine. The system has a bleed means for bleeding a portion of a first core of gas exited from a compressor section of the engine to thereby form a second core of gas. The second core of gas is additionally pressurized by a second compressor means to increase the pressure of the second core of gas. The second core of gas is then delivered to the turbine section for cooling of the engine such that the second core of coolant gas has a higher pressure than the first core of gas exiting the combustor section.
