Abstract: A gas turbine engine includes a main compressor section, a combustor, and a main turbine section. A fuel pump delivers fuel to the combustor. A tap taps air compressed by the main compressor section, and is connected for delivering the tapped air through a first heat exchanger and to a boost compressor. Air downstream of the boost compressor is connected to cool a component. Driving compressed air is connected to be delivered to a power turbine. The power turbine is connected to drive both the boost compressor and the fuel pump.

Abstract: A gas turbine engine includes a fan rotor, a compressor aft of the fan rotor, a combustor aft of the compressor, and a turbine section aft of the combustor, the turbine section configured to drive the compressor section and the fan rotor. A cooling air system includes an input connected to a compressed air tap, an output connected to at least the turbine section, and a heat exchanger having a first path and a second path. The first path is disposed between the input and the output. A valve and a propulsor are disposed along a lower pressure cooling air path. The heat exchanger second path is in fluid communication with at least a portion of the lower pressure cooling air path. The valve is configured to control flow within the heat exchanger second path. A cooling system and a method are also disclosed.
