Abstract: The paper presents the results of optimizing the workflow of a single-stage axial turbine to improve its efficiency while maximally preserving the original design. To solve the problem, a scheme for parameterizing the turbine blades and flow path contours was developed, taking into account design and technological constraints. The turbine nozzle blade is equipped with a deflector; to control the possibility of its placement, a special program was developed that automatically tracks the spatial position of the nozzle blade sections. A post-processing program was developed to control the flow parameters at the turbine exit along the height. The optimization criteria were efficiency and the deviation of the flow exit angle from the turbine along the height from the original one. The constraints were the working fluid flow rate and the total pressure drop across the turbine. The problem was solved in several stages with different variable parameters. As a result of solving the problem, it was possible to increase the turbine efficiency by 0.9%.
