The possible causes of residual deflections in seamless forged rotors are examined. It is shown that measures to eliminate a residual deflection must take its cause into account. A method for correction of rotors proposed by the Leningrad Metal Factory (LMZ), which involves mounting special systems of balanced and "antibalancing" loads on a bent rotor, is analyzed. Calculations show that even the elastic stresses owing to operation of a flexible rotor beyond its critical rotation frequency and, as a rule, exceeding those stresses which the authors of this method propose creating, do not result in correction of a bent rotor.
