AB - The problem of blade flutter prediction is relevant on the engine design stage. Modern technology of multidisciplinary simulation that combines the vibrating blade model and the response model of gas flow in gas dynamic tract is used in present paper to determine the influence of flow parameters on natural modes and frequencies. Geometrically nonlinear aeroelastic blade models (pre-twisted beam, shell and 3D solid body) that consider aerodynamic stiffness in the blade assembly are implemented. Aerodynamic stiffness coefficients are calculated on the base of CFD simulation results. Stability analysis for typical compressor and turbine blades is carried out. It is demonstrated, that centrifugal loads and flow speed change blade natural frequencies and modes, what has an influence on blade sensitivity to flutter. It is shown that connection between blade second bending and first torsion natural modes defines the condition of blade bending-torsion flutter initiation.
