description: This work is devoted to the study of the influence of the geometric dimensions of the guiding and working blades of the last stage on the efficiency of the turbine flow section. The tasks that were solved during the study are: 1. Substantiation of the significant influence of the last stage on the general characteristics of the turbine. 2. Study of the characteristics of the low-pressure cylinder by sections depending on different options of the geometry of the last stage. 3. Study of the dependence of the turbine efficiency on different options of the geometry of the last stage. 4. Development of recommendations for choosing the geometry of the last stage. The research was carried out using the methodology developed at the Leningrad Metal Plant (LMP), where the turbine under consideration in the study was already produced. The methodology includes mathematical modeling using a program of one-dimensional gas-dynamic calculation. The calculations carried out visually demonstrate the influence of the geometric parameters of the last stage on the efficiency of the turbine flow section at different pressures. As a result, the influence of the dimensions of the last stage and the vacuum at the turbine outlet on the efficiency indicators of the turbine flow section was analyzed. Based on the conducted research, certain recommendations were made regarding the choice of the geometric dimensions of the last stage.
