This article presents the results of studies of a sailing wind power plant at various parameters. For this purpose, a model of a wind power plant controlled by a system of sail blades was developed. Studies of aerodynamic forces at different angles of deflection of the sail blade system were carried out: 0°; 30°; 60°; 90°. The air flow velocity varied in the range from 3 to 14 m/s. The experiments were carried out in a T-1-M wind tunnel designed to measure forces and moments acting on a sailing wind turbine. As a result of experiments, it was found that with an increase in the air flow velocity, the frequency of rotation of the shaft of the wind power plant increased. The maximum rotational speed of the shaft was reached at α = 0° deflection of the sail blade system of the wind power plant. A number of experiments were carried out and aerodynamic characteristics were obtained depending on the deflection angle (α) of the sail blade system of the wind power plant and the air flow velocity. As the deflection angle of the blade system increases, the drag force decreases depending on the air flow velocity. It was experimentally established that at α = 30° deflection of the blade system created the maximum lift force. Based on the data obtained, it was found that with an increase in the speed of the incoming air flow, the aerodynamic forces acting on the sailing wind power plant increased.
