Abstract

The wheel (1) is equipped with one or more blades (3) which have a leading surface (14) extending from outside the wheel as far as the hub (17); it is substantially plane and inclined rearwards in a zone located towards the outside of the wheel (cc'), and subsequently straightens so that at least the upper part of the blade containing the leading edge (10) is substantially perpendicular to the flange (2) in a zone near the hub (aa'). <IMAGE>
