Abstract
L'invention concerne une structure profilée, - allongée suivant une direction selon laquelle la structure présente une longueur (L1) exposée à un écoulement d'air (U), et - transversalement à laquelle la structure présente un bord d'attaque (164) et/ou un bord de fuite (165), dont l'un au moins est profilé et présente, suivant ladite direction d'allongement, des motifs géométriques de serration (28) définies par des dents (30) et des creux (32) se succédant. Le long du bord d'attaque et/ou du bord de fuite profilé(s), les motifs de serration (28) présentent un motif géométrique qui se répète suivant la direction d'allongement (L1), dont la forme présente un étirement et/ou une contraction : - transversalement à la direction d'allongement, et/ou - suivant la direction d'allongement.
