description: This work is devoted to the study of the influence of the angles of installation of the blades of the last stage on the efficiency of the flow part of steam turbines. In the course of the study, the characteristics of the flow part were calculated for different input data, the obtained characteristics were analyzed and structured. All parameters of the input data remained constant during the calculations, except for the variable exit angles from the blades at the last stage and the exit pressure from the turbine. Graphs are constructed depicting the dependence of the overall efficiency on the variable parameters, as well as the efficiency of individual stages and the main characteristics that affect this coefficient. Based on the analysis of the calculations and dependencies obtained, conclusions were drawn, and recommendations were drawn. The calculation is carried out based on the calculation methodology developed at the Leningrad Metal Plant (LMZ). Calculations were carried out showing clearly how the change in the output angles affects the efficiency of the flow part of the turbine. The analysis was carried out by the method of mathematical modeling using the program of one-dimensional gas dynamic calculation of the flow part. As a result, the dependence of the efficiency of the flow part on the vacuum and the specified parameters of the blades was analyzed. Based on the results obtained, the best variant of the values of the exit angle from the blades at the last stage for the considered values of the turbine exit pressure is assumed.
