Abstract:
1. A de-icing system for a fixed or rotary aircraft wing, the system being capable of generating ultrasound that is transmitted to an outside surface of the wing, the wing including a base structure covered at least in part by at least one leading edge, the system including: piezoelectric actuators; a support structure for the 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 the cells, each cell defining a housing that is open towards the leading edge, the 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; and fastener means for fastening the leading edge to the base structure and to the piezoelectric actuators.
