An anti-icing system for an engine section stator of a gas turbine engine. The system includes an environmental control system pre-cooler heat exchange system and a conduit. The environmental control system pre-cooler heat exchange system is configured to exchange heat between air bled from a compressor of the engine and bypass duct air. The conduit is configured to exchange heat from the pre-cooler heat exchange system to a heat transfer medium. The conduit is also configured to transfer the heat from the heat transfer medium to the engine section stator.

Gas turbine engine anti-icing system

A cooling system for a gas turbine engine. The system includes a fuel air heat exchanger with a fuel passage that is in thermal contact with an engine cooling air passage. The system further includes a fuel deoxygenator located upstream of the fuel air heat exchanger and configured to deliver deoxygenated fuel to the fuel air heat exchanger fuel passage. The system also includes a valve configured to moderate engine cooling air flow to the engine cooling air passage.

Gas turbine engine with cooling system

The invention relates to a heat exchanger, comprising: a first unithaving a first conduitfor passing a flow of a first fluid through the first unit; a second unithaving a second conduitfor passing a flow of a second fluid through the second unit, wherein the flow of the first fluid is isolated from the second unitand the flow of the second fluid is isolated from the first unit; and, a third conduitconnecting the firstand secondunits, wherein the third conduitis for carrying a flow of an intermediate fluid between the firstand secondunits so as to transfer heat between the first fluid and the second fluid, when in use.
