An auxiliary power unit (APU) inlet muff anti-icing system that uses high pressure, high temperature APU compressor delivery air to melt any accumulation of ice and snow near the bottom of the muff with a tracer line coupled to a perforated gull wing fairing mounted within the inlet muff and that uses the compressor delivery air as the primary stream for an ejector to suck ice and snow melt accumulating near the fairing overboard.


What is claimed is: 1. A system for removing accumulations of ice and snow from the bottom of inlet muff of an auxiliary power unit (APU), comprising: a gull wing fairing mounted within the inlet muff to direct inlet air into an inlet of the APU that has a plurality of perforations to allow air and liquid flow through the fairing into a stagnant air region of the inlet muff below the fairing; a tracer line comprising tubing that is arranged along a surface of the fairing in a general "zigzag" pattern that has an inlet coupled to a primary stream of high...
