De-icing system for a fixed or rotary aircraft wing

A de-icing system for a fixed or rotary aircraft wing, the system comprising means for generating ultrasound that is transmitted at least locally to an outside surface of the wing, the wing including a base structure covered at least locally by at least one leading edge, wherein the system includes piezoelectric actuators and a support structure for said piezoelectric actuators, the support structure being arranged and secured between the base structure and the leading edge, the support structure including cells and being pierced to include empty spaces between said cells, each cell defining a housing that is open towards the leading edge, said piezoelectric actuators being arranged in at least some of the housings in order to generate ultrasound waves that propagate in at least one direction substantially in parallel with the outside surface, wiring connecting the piezoelectric actuators to an electrical control and power supply unit, said system including fastener means for fastening the leading edge to the base structure and to said piezoelectric actuators arranged in their respective housings.
