The method involves obtaining the local-dependent data related to the radial positions of profile of rotor blade (2). The trailing edge (1) of rotor blade is formed with a serrated portion having several teeth (8). Tooth height and width are calculated depending on the obtained data related to the radial positions of rotor blade profile. The ratio from tooth height to tooth width is set within the range of 0.5-10. |
