Abstract
Deicing of fixed wing aircraft and rotor craft that fly; at lower altitudes has been an area of research interest for many decades. The currently available solutions, though functional, are economically or environmentally inefficient. Some military helicopters have electrical deicing system for rotor blades that use up to 12 kW of power to achieve all weather shear horizontal waves at the ice-substrate interface is proposed. Experiments were carried out using PZT-5A and PZT-8 shear plate actuators bonded to an aluminum plate. A low-temperature chamber was constructed for this purpose. The results indicate that the PZT-8 actuators were able to deice the aluminum plate melting the ice at the interface. Results are presented in the form of tabular data and digital photographs taken of the melting process. The deicing mechanism is discussed.
