Abstract

Procédé de formation du flux d'air dans le système de sortie d'un compresseur centrifuge consistant à faire sortir de façon non simultanée le flux des ailettes de la roue de travail sur son épaisseur et à déplacer, dans le système de sortie, à partir du sens circulaire, les flux provenant des ailettes avec une avance de temps du côté des flux alimentés avec un retard. Un compresseur centrifuge est caractérisé en ce que les bords arrières (10) des ailettes (2) de la roue de travail (1) présentent des dépressions réduisant les rayons de rotation de ces bords dans le corps des ailettes, et les éléments fixes (8) du système de sortie pénètrent dans ces dépressions et ont une forme correspondant au profil desdites dépressions.
