Abstract
Structure portante à profil adaptable de manière passive L'invention a pour objet une structure portante (46) positionnée dans un flux de fluide (44), caractérisée en ce qu’elle est configurée pour se déformer de manière élastique, sur au moins une partie de la structure portante (46), entre un premier état de repos en l’absence de contrainte extérieure et un deuxième état déformé en présence de contraintes extérieures induites par le flux de fluide (44) en raison d’un changement d’orientation de la structure portante (46) et/ou du flux de fluide (44). L’invention a également pour objet un aéronef comportant au moins une telle structure portante (46). Figure 6
