FIELD: engines and pumps.
SUBSTANCE: invention relates to drive engineering and can be used in assembling the turbomachine impeller blades. For each blade of a plurality of frequency of intrinsic oscillations at the most dangerous shape and weight are measured to define complex criterion, which considers weight characteristics and intrinsic oscillation frequency of blades at the most dangerous form, set consists of blades which complex criterion values deviation from its average value does not exceed specified value, arrangement scheme is selected, at which the spread of values of complex criterion of neighbour blades approximates to its average value and the blades are installed at disk slots by values of complex criterion. Blade weight or static moment or total blade static moment is selected as weight characteristics.
EFFECT: higher resistance of turbo machine impeller against self-excited vibrations at the level of impeller unbalance in accordance with requirements of the design documentation.
