The phenomenon of aircraft icing poses a significant threat to flight safety. There is considerable potential for piezoelectric actuators based on deicing techniques. The focus of this paper is to examine the correlation between vibrational frequency and heating properties of piezoelectric stack, as well as the effect of the piezoelectric stack heating on deicing. The findings indicate that the heating rate of the piezoelectric stack is significantly affected by its vibrational frequency. Short-term and low frequency (below 1000Hz) vibration of the piezoelectric stack at -16°C of environment have slight impact on deicing.
