Abstract

Rotor (6) de turbomachine muni d'ailettes (3) conçues de telle sorte que la différence de pression statique réduite DELTA Cp entre le moyeu (2) et la virole (4) sur la surface d'aspiration (3c) de l'ailette (3) présente une tendance notablement décroissante à proximité de la sortie du rotor (6b) dans la direction de la sortie du rotor (6b) entre l'entrée du rotor (6a) et la sortie du rotor (6b).
