Abstract: The study discusses the vibrations of rotor wheels with non-identical blades. Due to disturbance of a rotational symmetry the eigenmodes of wheels are always characterized by distortion of the harmonic distribution law for the displacements along the circumference (the distortion of eigenmodes). It has been established that the value of the distortion and hence the degree of disturbance of rotational symmetry of a wheel depends not only on how much different blades from one another are but also on connectivity ofvibrations. The process on distortion of eigenmodes by rotor wheels with disturbance of rotational symmetry with decreasing of connectivity of blade vibrations to complete disappearance of the symmetry is studied.
