Abstract: A gas turbine engine includes a main compressor section having a downstream most location, and a cooling air tap at a location upstream of the downstream most location. A main turbine section, each of the main turbine section and the main compressor section are mounted within a housing, and each have rotatable components. A first heat exchanger is connected to the cooling air tap. The first heat exchanger is also connected to receive fuel to be supplied to a combustor in the gas turbine engine, and such that the fuel may cool the cooling air in the first heat exchanger. A boost compressor is connected to receive air downstream of the first heat exchanger and connected to deliver the cooling air to at least one of the rotatable components in at least one of the compressor and turbine sections.

Abstract: A lubricant supply system for a gas turbine engine has a lubricant lube pump delivering lubricant to an outlet line. The outlet line is split into at least a hot line and into a cool line, with the hot line directed primarily to locations associated with an engine that are not intended to receive cooler lubricant, and the cool line directed through one or more heat exchangers at which lubricant is cooled. The cool line then is routed to a fan drive gear for an associated gas turbine engine. A method and apparatus are disclosed.

Abstract: A gas turbine engine according to an exemplary embodiment of this disclosure, among other possible things includes a fan. A geared architecture is configured for driving the fan. A turbine section is configured for driving the geared architecture. A thermal management system that includes a first fluid circuit and a second fluid circuit that manage heat generated in at least a portion of the gas turbine engine. A first heat exchanger is incorporated into each of the first fluid circuit and the second fluid circuit. A second heat exchanger is incorporated into the first fluid circuit. A valve controls an amount of a first fluid that is communicated to the first heat exchanger and the second heat exchanger. A controller is configured to control a positioning of the valve. The amount of the first fluid communicated to the first heat exchanger is based on a first characteristic of a second fluid and the amount of the first fluid communicated to the second heat exchanger is based on a second characteristic of the second fluid. A method and a system are also disclosed.
