FIELD: turbine manufacture. SUBSTANCE: method of replacement of axial-flow compressor moving blades dispensing with subsequent rotor balancing involves replacement of faulty blades and installation of spare ones instead of them. In removal of faulty blades difference in static moments or masses of each faulty blades and that installed in the place is measured. Vector of blade ring unbalance is measured by two independent methods whose validity is evaluated by convergence of results. Unbalance vector is eliminated by fitting unbalance members arranged in blade ring plane and then impeller is reassembled. EFFECT: facilitated procedure. 8 dwg
