The centrifugal compressor impeller (9) comprises an inlet, an outlet and a disk (23) extending from the inlet to the outlet. A plurality of blades (25) extend from the disk (23), each blade having a leading edge (25L) at the inlet, a trailing edge (25T) at the outlet, a blade base (25B) extending along the disk between the leading edge and the trailing edge, and a blade tip (25A) extending between the leading edge and the trailing edge opposite the disk. The trailing edge is S-shaped with an intermediate inflection. |
