Abstract The results of studies on determining the speed of a wind-power plant and calculating the wind-energy utilization factor of a rotating cylinder of constant cross section with a smooth surface are presented. Experimental and theoretical methods were used to study the main aerodynamic characteristics of the efficiency of a wind turbine with blades in the form of rotating cylinders. The changes in the aerodynamic parameters of the flow were 2 m/s and higher. The results showed that, the value of the wind-energy utilization coefficient decreases with an increase in the speed of the oncoming flow. It has been experimentally established that the value of the speed of a wind-power plant decreases with an increase in the Reynolds number.
