The technique of designing of effective flow-through parts of the turbomachines, based on use of a method of analytical profiling and model of a three-dimensional viscous flow of steam is presented. In a method of parametrization and analytical profiling of scapular wreaths profiles of blades are described by polynoms of the fourth degree with a condition of maintenance of the minimum value of the maximum curvature. Model of viscous flow of steam is implemented in software package FlowER. Modernization of the first two stages of the high-pressure cylinder of steam turbine K-325-23,5 in which result has raised gas-dynamic efficiency of the flowing part both on nominal, and on partial operating modes is executed. On the basis of the modernized flowing part of the first two stages of the high-pressure cylinder the estimation and numerical research of an opportunity of use rotary blade the directing device of the first and second steps for improvement of maneuverable characteristics of the turbine is executed. It is supposed, that in the future the executed development will be introduced on all new power steam turbines.
