Abstract (en)
[origin: WO2010103055A1] The invention relates to a mobile wheel for a centrifugal or axial centrifugal compressor for a turbine engine, that comprises a base (2) on which a plurality of vanes (3) are attached at their feet (6) and extend between a leading edge (8) and a trailing edge (9), said trailing edge being inclined at the base (6) of the vane (3) by a slope angle a relative to the middle plane extending through the base thereof in the rotation direction of said compressor (1), characterised in that the trailing edge (9) has at the head (7) of the vane (3) a slope angle ß smaller than the slope angle a at the vane base.
