| Abstract: | Problems of optimum hanging of long rotor blades of the last stages of steam turbines are considered. Causes of nonuniform
erosion wear of the inlet edges connected with inaccurate location of holes for the external damper coupling on the chord
of the profile are determined. Methods for optimizing the hanging of blades for raising the reliability of the last stages
are suggested. Main results of hanging performed with the help of a specially developed “LIBRA” soft hardware are presented.
