An impeller (6) in a turbomachin- ery has blades (3) designed such that re- duced static pressure difference .DELTA.Cp be- tween the hub (2) and the shroud (4) on the suction surface (3c) of the blade (3) shows a remarkably decreasing tendency in the vicinity of the impeller exit (6b) as it approaches the impeller exit (6b) be- tween the impeller inlet (6a) and the im- peller exit (6b).
Roue (6) de turbomachine possédant des ailettes (3) conçues de telle manière qu'une différence de pression statique réduite (.DELTA.Cp) entre le moyeu (2) et le carénage (4), sur la surface d'aspiration (3c) de l'ailette (3), tend à décroître de façon remarquable dans le voisinage de la sortie (6b) de la roue, au moment où le fluide possédant cette différence de pression s'approche de la sortie (6b) de la roue, en un point situé entre l'entrée (6a) et la sortie (6b) de la roue.
