Hybrid acoustic and induction-heating systems and methods for impeding formation of ice
An airfoil comprises a skin, comprising an external surface and an internal surface. The skin has a controlled region. The airfoil also comprises an interior space, formed by the skin. The airfoil additionally comprises a hybrid acoustic induction-heating system, configured to impede formation of ice on the external surface. The hybrid acoustic induction-heating system comprises an induction coil and a control system. At least a portion of the induction coil is sufficiently close to the internal surface to produce an eddy current within the controlled region when an alternating electrical current is flowing in the induction coil. The control system is configured to generate inductive heat and acoustic pressure in the controlled region by supplying the alternating electrical current to the induction coil based, at least in part, on an ambient temperature of a layer of fluid flowing over the external surface.
