Abstract:
An airfoil (200) comprises a skin (210), comprising an external surface (212) and an internal surface (214). The skin (210) has a controlled region (216). The airfoil (200) also comprises an interior space (208), formed by the skin (210). The airfoil (200) additionally comprises a hybrid acoustic induction-heating system (202), configured to impede formation of ice on the external surface (212). The hybrid acoustic induction-heating system (202) comprises an induction coil (230) and a control system (250). At least a portion (236) of the induction coil (230) is sufficiently close to the internal surface (214) to produce an eddy current (280) within the controlled region (216) when an alternating electrical current (234) is flowing in the induction coil (230). The control system (250) is configured to generate inductive heat and acoustic pressure in the controlled region (216) by supplying the alternating electrical current (234) to the induction coil (230) based, at least in part, on an ambient temperature of a layer of fluid (218) flowing over the external surface (212).
