Abstract

La présente invention concerne un ensemble (1) d'au moins une première aube (2) de soufflante (50) et d'une deuxième aube (4) de soufflante (50), l'ensemble (1) présentant: une région aérodynamique inférieure (7) et une région aérodynamique supérieure (8), superposées selon une direction radiale (Z). De plus, au niveau de la région aérodynamique inférieure (7) la première aube (2) et la deuxième aube (4) coïncident de sorte à définir un unique profile aérodynamique (10), et au niveau de la région aérodynamique supérieure (8) la première aube (2) et la deuxième aube (4) définissent deux profils aérodynamiques (24) différents.
