The paper focuses on the optimal centrifugal compressor stage design and introduces a new approach to it that implies replacing a physical experiment with a numerical one. The efficiency of this approach is due to numerical testing of a large number of different variants of the compressor stage geometry for the same gas-dynamic parameters. Within the approach, for calculating and optimizing the compressor stage parameters, we developed a combined method not having the most empirical components. Relying on this method, we propose methods for calculating the parameters and optimizing the geometry of the compressor stage.
