The present invention refers to the configuration of a leading edge section (1) with laminar flow control, wherein the leading edge comprises: a perforated outer skin (2), an inner surface (3), a plurality of suction chambers (4) formed between the outer skin (2) and the inner surface (3) and a plurality of radial structural elements (5) to withstand structural loads at the leading edge. The radial structural elements (5) are arranged to define the suction chambers (4) together with the outer skin (2) and the inner surface (3), and the radial structural elements (5) and/or the inner surface (3) are perforated, such that an exterior region of the leading edge is communicated with an interior region of the leading edge through said suction chambers (4). The invention provides an optimized leading edge with a laminarflow control system, from a structural point of view, including improved bird impact performance.
