Essay

Generalized discreet model of bladed assembly of rotor wheel as a typical object of inquiry is developed. For determination of aerodynamic coupling parameters the usage of flat airfoils cascade is justified. The algorithm for frequency and mode spectrum determination of the considered system on the basis of perturbation method is developed; the peculiarities of its application and usage bounds are determined. The influence of aerodynamic coupling of subsystems on forming of characteristics of natural and resonant vibrations of systems with strict cyclic symmetry and mistuned one is determined.
