In this work the dynamic behavior of blade disc - turbo rotor - bearing system isinvestigated analystically using the transfer matrix method, also the analysisapplies the finite element method ( Ansys Package ) choosing the brick typeelement, for comparison of the results. The major aim of this paper are to study theeffects of varying the temperature, fluid flow impact on the blades surface; losing afaction of the blade mass to have imbalama in system; blade root flexibility andcentrifugal force along the blade length; gyroscopic moments, damping andstiffness values of bearings on the dynamic behavior of the blade disc – Turborotor – Bearing system.
