The numerical analysis of the influence of geometrical and regime parameters as well as the temperature distribution and cooling methods for unsteady blade loading and blade oscillation modes in the compartment of axial turbomachine have been developed. A mathematical model of three-dimensional turbulent flow of viscous flow in turbomachines with taking into account laminar-turbulent transition and improved procedure of boundary conditions has been developed. A new iterative implicit finite-difference scheme for the integration of systems of equations of gas dynamics has been developed. The solution to the problem of spatial profiling turbomachinery blading using three-dimensional models of viscous flow and hybrid optimization techniques have been developed. There developed software package optimization methods to improve aerodynamic blading stages of steam and gas turbines.
