Abstract (en)

[origin: EP1724440A1] The method involves optimizing an inflow of a third of three consecutive blade rings. Appropriate operating parameters are ascertained or predefined to select an operating state of a turbine-type machine. A tolerance angle is determined in the operating state. Positions or geometries of blade profiles of one of the three blade rings, situated at a certain blade height, are modified until the tolerance angle is within a predefined tolerance angle.
