The results of experimental studies on estimating the lift force and lift coefficient of a rotating cylinder of constant cross section are presented. The data on the effect of the flow rake angle on the aerodynamic characteristics of rotating cylinders within a range of angles from 0° to 90° are analyzed. It has been established that a decrease in the lift coefficient is observed at flow rake angles above 30°, so the wind engine element shows a positive result within a range of rake angles from–30 ° ≤ α ≤ 30°. The data of these experimental studies can be used for the development of wind engines with blades designed as rotating cylinders with a smooth surface.
