A method for producing a skin of a leading edge for an aircraft wing element, including an assembly of resistive heating elements designed to form an integral part of a system for de-icing and/or anti-icing of the leading edge. The method includes curing a stack in a mold between two molding surfaces facing each other. The stack includes the resistive heating elements assembly, two adhesive films arranged respectively on either side of the assembly so that the heating elements adhere to each of these two adhesive films, two layers of electrically insulating pre-impregnated fibers adhering respectively to the two adhesive films on the sides opposite those receiving the heating elements, and a plurality of layers of pre-impregnated carbon fibers.

Method for producing a leading edge skin by baking a stack incorporating heating elements and layers of pre-impregnated fibres

An aircraft wing comprising a wing fixed central body, and a leading edge mobile slat () designed to be moved in rotation relative to the fixed central body along a circular trajectory inscribed on a sphere with center (C). According to the invention, the wing also comprises a cable carrier chain () comprising links () articulated to each other through articulation axes () that converge towards a single point, the chain being connected at its two ends to the fixed central body and to the mobile slat. Furthermore, the single point is the center (C) of the sphere, located on a rotation axis () of the leading edge mobile slat relative to the wing fixed body.
