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 induction coils and a control system. Each one of the induction coils has a portion, arranged sufficiently close to the internal surface to produce an eddy current within the controlled region. The control system is configured to generate inductive heat and traveling-wave acoustic pressure in the controlled region by supplying different phases of the alternating electrical current to the induction coils based, at least in part, on an ambient temperature of a layer of fluid flowing over the external surface.
