Determination of the aerodynamic characteristics of a wind power plant with a vertical axis of rotation

Wind energy is a commercially proven and rapidly developing type of electricity generation. power plants with vertical axis are more attractive better suited for use in cities urban environments where wind flow less predictable compared to widespread horizontal rotation. This makes them much choice both ground installation and/or mounting on buildings roofs that would otherwise limit the higher turbine structures. The paper describes an experimental study drag force its coefficient turbines object laboratory model blades made form rotating cylinders fixed blade. Experimental studies were carried out T-1-M tunnel, measurements aerodynamic using three-component scales. A distinctive feature work combined lifting cylinders, as well plate. Due this solution, when comparing existing rotation, it was found question prevails by 25‒100 % number revolutions. dependences velocity Reynolds from 1·104 4·104 obtained. An uncertainty analysis also order determine A, B total uncertainty, which measurement error 1.13 %. field practical application results obtained will be useful development prototypes rotation
