Based on exploring the effect mechanism of ultrasonic on icing blades, the interface stress of each layer in composite lamellar were derived based on potential function. According to the similarity principle, the physical model and finite element model of blade de-icing in FEA software were established. By numerical calculation, the method for determining the optimal de-icing frequencies of ultrasonic waves was obtained. By using six sets ultrasonic de-icing equipment developed by the authors of this paper, the blade de-icing experiments in an artificial environment laboratory were completed. Through comparing the numerical results and experimental results, the validity of numerical data was verified, and the reliability of ultrasonic de-icing prototype system designed by authors was analyzed.
