The blade has a blade portion (2) comprising a forward edge (4), a rear edge (6) and a blade tip (12), where a pressure side (8) and a suction side (10) extend among the forward edge, the rear edge and the blade tip. A pressure-side variation profile i.e. shaft profile (14), extends into the rear edge and the blade tip. A recess is formed in a region with a maximum pressure gradient. The variation profile is oriented transverse to a flow direction (X) of the blade portion. The variation profile comprises a set of projections or crests and a set of depressions or troughs. An independent claim is also included for a compressor. |
