Abstract

L'invention concerne une structure d'entrée d'air (150) comportant une lèvre d'entrée d'air (158) et un cadre de renfort avant (160) placé à l'intérieur de la lèvre d'entrée d'air (158). La partie avant de la lèvre d'entrée d'air (158) présente une pluralité de secteurs (120) répartis angulairement le long du bord d'attaque de la lèvre d'entrée d'air (158), deux secteurs (120) voisins étant séparés par une partie intermédiaire présentant une surépaisseur. Chaque secteur (120) présente quatre bords (130a-b), chacun présentant une surépaisseur (122a-b) par rapport au reste du secteur (120). Ainsi, la lèvre d'entrée d'air présente une structure plus légère.
