description: This work is devoted to optimizing the flow part of the axial compressor. Tasks that were solved during optimization: 1. Construction of the flow part of a multistage axial compressor 2. Calculation of the characteristics of the initial geometry 3. Parameterization of the original geometry 4. Calculation of the parameterized geometry characteristics 5. Step-by-step optimization of the working blades of the RK and ON 6. The analysis of the results obtained Work was carried out based on the calculation of the axial compressor according to the CCTI method [1]. Three characteristics of the geometry were calculated: initial, parameterized, and optimized. The analysis of the gas dynamic parameters and the calculation itself were performed in the Ansys program. The grid independence of a separate stage was determined, the parameters of which were used for further calculations. The following modules were used for optimization: Design Modeler for constructing the geometry of the flow part, Turbo Grid for constructing the flow part grid, CFX Pre for configuring the solver, CFX Post for analyzing the results and setting target functions. After making calculations and constructing three characteristics, the analysis of the data obtained was carried out. It follows from this analysis that the optimizer was unable to find the initial characteristic and improve it, but the parameters improved relative to the parameterized model. The reasons why it was not possible to improve the initial characteristic are as follows: 1. The linear dependence of the angle along the length of the blade imposes great restrictions on the optimizer â not all geometry can be built. 2. The flow angle at the outlet of the NA was not optimized, so the NA could not cope with the deceleration of the flow, the CA was not optimized, which led to separation. 3. Many target functions for optimization. The mixing ratio , pressure ratio , efficiency, and optimizing all three of these parameters at the same time also imposes boundaries in our work.
