FIELD: mechanical engineering. SUBSTANCE: method is based on examination of position of blade peripheral parts in operating mode. To this end, angular distances between peripheral parts of blades are measured, and if angular distances between definite blade and all remaining blades exceed rated value specified by operating spread of blade parameters, this blade is considered to be damaged. EFFECT: increased reliability of detection. 1 dwg
