Abstract

L'invention concerne un ensemble de circulation d'un écoulement d'un flux d'un turboréacteur d'un aéronef comprenant un moyeu interne (3) et un carter externe (2) définissant un canal (II) de circulation de l'écoulement du flux, l'ensemble comprenant une structure (5, 6) rainurée comprenant une succession de rainures, en contact avec l'écoulement du flux, les rainures s'étendant dans le sens d'écoulement du flux, la structure rainurée comprenant au moins un paramètre géométrique (s, h, h/s) configuré pour s'adapter en fonction d'au moins un paramètre de l'écoulement de flux.
