Abstract

Protection systems against ice on leading edge conventionally use thermal and pneumatic solutions. In case of thermal solutions with piccolo tubes (the most usual technology), the hot air is extracted from engine, which decrease its efficiency. The trend is to move to all electric deicing systems. Electro-thermal solutions have been implemented but at the cost of a high energy consumption. This work focuses on low-consumption electromechanical deicing solutions based on piezoelectric transducers. After a review of deicing systems, the main features of electromechanical de-icing devices are identified and piezoelectric ceramic-based deicing systems are studied. Numerical simulations allow computing the configurations that lead to low-consumption, compact ultrasonic deicing devices. First tests of piezoelectric de-icing systems are performed on simple cases such as plates. These tests are promising and allow analyzing the key design drivers (the frequency range to use, the impact of the ice thickness on the system performance) for the design of such systems. First results on the voltage and the consumed current of such devices are also given.
