CA 2218692
An impeller (6) in a turbomachinery has blades (3) designed such that reduced static pressure difference .DELTA.Cp between the hub (2) and the shroud (4) on the suction surface (3c) of the blade (3) shows a remarkably decreasing tendency near the impeller exit (6b) as it approaches the impeller exit (6b) between the impeller inlet (6a) and the impeller exit (6b).
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).
