Abstract
A de-icing system for a fixed or rotary aircraft wing. The system is capable of generating ultrasound that is transmitted at least locally to an outside surface of the wing, wherein the system comprising a base structure (2) covered at least locally with at least one leading edge (3), an elastomer structure (1) arranged and secured between the base structure (2) and the leading edge (3), housings (4) defined in the elastomer structure (1) and open towards the leading edge (3), piezoelectric actuators arranged in at least some of the housings (4) in order to generate ultrasound, wiring (10) connecting the piezoelectric actuators to an electrical control and power supply unit, and a fastener for fastening the leading edge (3) onto the base structure (2) while coming into contact with the piezoelectric actuators (4a) arranged in their respective housings (4).
