FIELD: mechanical engineering; turbomachines.
SUBSTANCE: proposed method of arrangement of turbomachine rotor blades comes to measuring radial static moment of great number of blades to be fitted on rotor. Then said blades are classified into pairs and installed on rotor with diametrically opposite arrangement of blades of said pairs. Blades are classified into pairs by successively selecting blades with maximum values of radial static moment from great number of blades, and blades of chosen pairs are installed near previously installed pairs of blades following order of decreasing of their radial static moments. After mounting of each pair of blades, direction of pass and arrangement of blades in pair changed so that blades with maximum radial static moments of preceding and following pairs be in different semiplanes of rotor disk.
EFFECT: reduced value of initial unbalance of rotor at assembling, reduced mass of rotor.
