Abstract

L'invention concerne un turbocompresseur à écoulement axial comprenant une ou plusieurs parties stator espacées axialement (14) ayant chacune un réseau circonférentiel d'aubes directrices (15), et une ou plusieurs parties rotor (12, 16) ayant chacune un réseau circonférentiel d'ailettes de rotor (13, 17; A, B). Entre les ailettes de rotor successives (A, B), on trouve des chemins d'écoulement, tandis qu'entre les parties stator et rotor, on trouve des espaces axiaux (22, 23, 24) dont la configuration diverge, de façon à former dans chaque chemin d'écoulement, une zone de diffusion (C) qui s'étend de la section transversale la plus étroite (a¿2?) du chemin d'écoulement situé à une certaine distance en amont du bord d'attaque d'une seconde ailette de rotor (B) à une section transversale plus large (a¿3?) située approximativement sur le bord d'attaque de la seconde ailette de rotor (B), chaque chemin d'écoulement comprenant une zone de transition (D) d'une zone de section transversale n'augmentant sensiblement pas qui s'étend de la section transversale plus large (a¿3?) aux bords arrière des ailettes de rotor (A, B).
