In this article, a wind power plant with a horizontal axis of rotation operating under conditions of variable wind speeds is considered. For this purpose, a mock-up of a wind power plant with rotating combined blades was made. During the experiments, the angle of the fixed blade relative to the cylinder changed from 0° to 60°, in increments of 15 °. The air flow rate varied, from 3 to 12 m/s. The analysis of the results of the experiment on the change of the rotation frequency from the air flow velocity of the wind power plant is carried out. When changing the position of the fixed blade (0°, 15°, 30°, 45°, 60°) the value of the thrust force changes relative to the air flow in direct proportion. As the air flow velocity increases, the rotation frequency of the wind wheel increases linearly. It was found that when the fixed blade was positioned at an angle of 60 degrees, with a maximum air flow velocity of 12 m/s, the thrust force reached 2.06 N. Due to the combined use of two lifting forces, such as a cylinder and a fixed blade, increased thrust values are observed. The results obtained are useful when creating prototypes of a wind power plant with combined blades.
