The invention relates to a mobile leading edge flap (16), for a main wing of an aircraft, said flap comprising an aerodynamic skin (18), with a front region subject to bird impacts (24) and a rear skin (28), fixed to the aerodynamic skin (18), said flap also comprising a number of ribs (34), distributed over a longitudinal direction of the leading edge (X'). According to the invention, the flap further comprises a single rigid wall for diverting the trajectory of birds (42), arranged between two directly adjacent ribs, fixed to the skins (18, 28). Furthermore, in a section taken in a plane orthogonal to the direction (X'), said wall (42) forms an angle (A1) of less than 45~ with a geometric chord (26) of the flap.
L'invention concerne un volet mobile de bord d'attaque (16) d'une aile principale d'aéronef, ce volet comprenant un revêtement aérodynamique (18) présentant une zone frontale sensible aux impacts d'oiseaux (24), ainsi qu'un revêtement arrière (28) solidaire du revêtement aérodynamique (18), le volet comportant également une pluralité de nervures (34) espacées le long d'une direction longitudinale de bord d'attaque (X'). Selon l'invention, le volet comprend en outre, entre deux nervures directement consécutives, une unique paroi rigide déviatrice de trajectoire d'oiseau (42) montée fixement sur les revêtements (18, 28). Par ailleurs, en section prise selon un plan orthogonal à la direction (X~), la paroi (42) forme avec une corde géométrique (26) du volet un angle (.alpha.1) d~une valeur inférieure à 45·.
