Abstract

A turbocharger includes a plurality of blades (7; 7′) which are arranged in a turbine casing (2). Each blade has the following: a profile underside (8; 8′) and a profile top side (9; 9′) which determine the blade thickness, a blade leading edge (10; 10′) at a first intersection of the blade underside (8; 8′) and the blade top side (9; 9′), a blade trailing edge (11; 11′) at a second intersection of the blade underside (8; 8′) and the blade top side (9; 9′), a profile center line (12; 12′) which is defined by the blade underside (8; 8′) and the blade top side (9; 9′) and runs between them from the blade leading edge (10; 11′) to the blade trailing edge (11; 11′), and in which the profile center line (12; 12′) runs in a wave-like manner.
