The impeller has a wheel disc (12) and blades (14) with a leading edge (16) and a trailing edge (18) that are arranged in a circumferential direction. A partial area of a surface of the blades is a dual-curved partial area (26), whose generatrix (24a) is formed as curved lines, where the partial area is curved perpendicular to the generatrix. A transfer of the dual curved partial area is continuous to a standard surface partial area (28). The blades have a hub edge (20) and an outer edge (22), where the partial areas (26, 28) abut at the outer edge and the hub edge, respectively. An independent claim is also included for a method for manufacturing a radial compressor impeller. |
