摘要

At present NPO Saturn possesses the complex of technologies, which allow obtaining the most efficient technical solutions when creating up-to-date gas-turbine engines and their components. In this paper there are presented the examples researches aimed at axial compressors perfection basing on up-to-date analysis and optimization tools. As the analysis tools there are used the well-known commercial software packages (CFX-TASCflow, ANSYS etc.), as well as the models developed by NPO Saturn; the adequateness of latter had been proved by experimental data. To rise the efficiency and margins of gas dynamic stability for multistage axial compressors NPO Saturn is using widely the methods of CFD and optimization based on IOSO technology. In the paper there are presented some examples of real-life problems solution.
