A method of deicing an airfoil is provided. In preferred embodiments, the method comprises coupling a plurality of piezo-electric transducers (PETs) to an inside surface of an airfoil. The PETs are electrically coupled to a DC-DC converter and a first inverter. The PETs are driven by sweeping the driving frequency of the plurality of PETs over a frequency range that spans at least 10 kHz and 100 kHz. In preferred embodiments, some PETs are driven at a phase shift to the other PETs.
