Abstract

L'invention concerne un rotor (4) pour une turbomachine régénératrice (2). Ce rotor présente des aubes, pour lesquelles la zone d'entrée (15) est décalée de la zone de sortie (16). La zone d'entrée (15) est reliée à la zone de sortie (16) par une zone de transition (17) inclinée. Le rotor assure un rendement excellent à la turbomachine régénératrice (2) et peut être fabriqué d'une manière particulièrement peu onéreuse.
