The article presents the results of examining a wind turbine on the vertical axis of rotation. The study was conducted in an open circuit wind tunnel Gunt HM 170 in the laboratory of the Department of Thermodynamics, Fluid Mechanics and Aviation Propulsion Systems at Lublin University of Technology. The subject of research was a rotor based on the patent PL 219985, with blades capable of altering the surface of the active area (receiving kinetic energy of the wind). The study was performed on appropriately scaled and geometrically similar models maintaining, relevant to the type of research, the criterion numbers. The studied rotors with different blade inclination angles were produced using a 3D powder printer ZPrinter® 450. The results of the conducted research were obtained for the flow velocity of 6.5 m/s and three inclination angles, 30°, 60°, and 90°, at variable rotational speed. The test equipment used in the study allows maintaining the required speed, recording velocity and torque, which in turn allows an engineer to measure such characteristics of torque and power as a function of rotor speed.
