description: In this final qualifying work of the bachelor, was optimized the prototype of the A1-0,7+ÐÐ23 stage. The calculation of the stage was carried out in the Ansys program, then, after analyzing the obtained gas-dynamic characteristics, the calculation of the return channel was performed using the NZL method. Also, one of the tasks was to reproduce the geometry of the three-link stage A1-0.7 + LD23 using the DesignModeler module of the Ansys software package. Next, the mesh was generated using the Turbogrid module and the solution was executed in the CFX Solver module. Thus, a study was carried out on three different return channels in the same stage. The results of this study are the numerical modeling of the stage with the initial RC, further optimization, which was carried out in accordance with the NZL method, and the third stage was the optimization of the ONA obtained by the NZL method. Optimization was carried out by measuring the angle Î±5 on the streamlines, which were obtained in the previous calculations. This method is not calculated, but it is sufficiently accurate for the given movement in the pivoting knee, which makes it possible to determine the angle of entry into the RC quite accurately, and such optimization shows acceptable results.
