An anti-ice formation device for a gas turbine engine is configured to be mounted within an inlet duct of the engine, and adjacent the gas turbine engine compressor inlet. The device is configured to selectively receive a flow of compressed air that is discharged from the compressor. Because the compressed air is relatively hot, the anti-ice formation device temperature increases to a temperature sufficient to prevent ice accumulation and formation in the engine inlet duct. The anti-ice formation device is also configured such that heat is not transferred to the compressor inlet housing. As a result, the anti-ice formation device does not cause impeller clearance variations, which would adversely affect engine performance.

What is claimed is: 1. An anti-ice formation device for a gas turbine engine that includes a centrifugal compressor having a compressor inlet across which is disposed a plurality of struts, the device comprising:a flow body configured to surround at least a portion of the compressor inlet and including an inner surface, an outer surface, and an inlet port, the inner surface defining a flow cavity, the inlet port extending between the flow body inner and outer surfaces and adapted to receive a flow of fluid;a mount structure spaced apart from the flow body and adapted to surround at least a portion of, and to be coupled to, the compressor inlet, the mount structure including at least one discharge flow passage formed therein; anda plurality of spaced-apart supports coupled to the flow body and the mount structure, each of the spaced-apart supports configured to extend across and align with one of the plurality of struts at least one of the supports including a flow passage formed therein that is in fluid communication with the flow body cavity and the at least one mount structure discharge flow passage.
