Abstract

A gas turbine engine de-icing system includes a heat exchanger (64). A coolant loop (92) is in fluid communication with the heat exchanger and is configured to circulate a heat transfer fluid. An engine oil loop (91) is in fluid communication with the heat exchanger and is configured to transfer heat to the heat transfer fluid. A gas turbine engine inlet structure has at least one fan inlet guide vane (110). A spray bar (99) is disposed at least partially in at least one fan inlet guide vane. The spray bar is in fluid communication with the coolant loop. The spray bar is configured to spray the heat transfer fluid onto an inner surface of the at least one fan inlet guide vane to de-ice the fan inlet guide vane.
