Make improvements to previously known methods of calculation. It is proposedto allocate an additional (along the surface current) elementary channels that can achieve output of rowsdiagrams parameters. Preparation thus permits the compressor, in turn, to calculate the characteristic of the developedengine steady and unsteady modes with high accuracy. The proposed method allows the selection ofgeometric parameters of blade rows, and in operation - perform account the influence on the characteristics ofchanges in the geometry of the blades (due to erosion, dirt, etc.). Allows you to analyze the effect of prepollutionand erosion of the blades to change the characteristics of the nodes, and the results of the identificationof the plant model to solve the inverse problem - to identify the actual values of pollution and erosion in specificstages and crowns. The resulting geometry of the rims may be used as an initial approximation for the boundaryconditions at the solid-state 3D modeling and gas-dynamic calculations in СAE- systems such as Ansys CFX.</p>Сascadesexperimental purgingflow angletheoretical pressureРешётка профилейэкспериментальная продувкаугол поворота потокатеоретический напор[1.
