Essay

The object: turbomachine blade row. The aims: increase of reliability of turbomachines by prognosing the unsteady aeroelastic performances of the blading during the design. The methods: mathematical and numerical modeling. The new approach: at first it was developed the mathematical model and numerical method to solve the aerodynamic equations and flexible oscillations system by use the modal model of blade dynamics. Results: development of scientific base and numerical solver to prognose of the aeroelastic performances of blading increase of reliability and resource prolongation of turbomachine operation. Develop: methods of solving of aeroelastic oscillations of the blade rows in transonic flow. The effecty: increase of reliability and resource prolongation of turbomachine operation. The fields: energy mechanical engineering.
