This study aimed to develop and evaluate the effectiveness of a new Savonius wind turbine scheme featuring a vertical fixed axle, which offers advantages in reducing metal intensity and operating time. The study employed theoretical analysis of existing wind turbine designs, a fixed-axle modular design, and aerodynamic modeling of the rotor profile to enhance the plant’s efficiency. As a result of the study, a new scheme of a Savonius wind turbine with a vertical fixed axle was developed. The proposed design helped significantly reduce the metal intensity of the plant by approximately 30%, resulting in lower manufacturing costs. The absence of a rotating shaft and its replacement with a fixed axle resulted in a reduction of friction in the support, thereby increasing the plant’s efficiency. Dynamic forces on the structure were also reduced, contributing to longer bearing life. The proposed design reduced metal consumption by approximately 1.5 times, resulting in a 35% reduction in production costs. Less frequent maintenance, once every two years instead of every six months, reduces operating costs by up to 40%. Reduced friction in the bearings and reduced dynamic loads increase reliability and extend bearing life by 25%. All in all, these factors increase the financial efficiency and competitiveness of the turbine in the renewable energy market. The practical benefits of the research for stakeholders are that engineers are able to implement simplified and reliable design solutions that reduce bearing loads and increase turbine efficiency.
