Looking for a low-energy solution to aircraft deicing? This research explores the potential of piezoelectric actuators in developing an avionic deicing system. The study proposes a system that utilizes lightweight piezoelectric actuators, activated at resonant frequencies, to vibrate the structure and break the ice with minimal power consumption. The study begins with the validation of a numerical method for optimal placement of the piezoelectric actuators and selection of the appropriate resonance mode. Deicing was successfully demonstrated with a power input density of 0.074 W cm⁻² and a surface ratio of 0.07 piezoelectric actuators per cm². The method was then applied to a representative aircraft wing structure. Finally, an adapted converter topology for deicing applications is presented. This proof of concept holds promise for developing efficient and effective ice protection systems for aircraft, reducing energy consumption, and improving overall safety. This innovative approach may pave the way for advanced deicing technologies in the aviation industry.
