Claim Text:
1. An ice protection system comprising: an aerodynamic surface comprising a leading edge having an external surface comprised of a non-magnetic material and a susceptor formed of a ferromagnetic material interior of and in thermal communication with the non-magnetic material that forms the exterior surface of the leading edge relative to an outer mold line of the leading edge of the aerodynamic surface, wherein the aerodynamic surface further comprises an acoustic liner comprising a honeycomb core, and an erosion control layer comprising the susceptor overlying the acoustic liner and defining perforations in communication with the honeycomb core; at least one induction coil positioned interior of the acoustic liner so as to be spaced apart from the susceptor by the acoustic liner; and a signal source configured to provide alternating current to the at least one induction coil to thereby generate an electromagnetic field that creates an eddy current in the susceptor so as to heat the leading edge of the aerodynamic surface.
