Abstract

The blade profile (28) has a blade stage and another blade stage, which is arranged in an axial direction (R) of the turbine assembly and is considered behind the former blade stage. The blade profile has a cross-sectional surface (27), which is S-shaped. The S-shaped cross-section surface is considered in a direction of a blade root to a blade head of the blade.
