The paper is devoted to the vertical axis wind turbine combined rotor computer-aided design. Itincludes the description of main types of vertical axis rotors and their structural parameters. It is solved theproblem of combined rotor structural and paramet... see more

The concept of a vertical-axis spiral wind rotor is proposed and implemented in the interest of adapting it to air flows from all directions and improving the rotor’s performance. A comparative study is performed between the proposed rotor and conventiona... see more

It is researched the problem of energetic efficiency increasing of wind energy plant with   vertical axis of rotation. For the solution of this problem it is proposed to use the adjustable blades.  It is determined the optimal angle of atta... see more

The goal of this paper is to increase the efficiency of using alternative energy sources, namely: to analyze the ways of controlling the angular position of the wind turbine blade. The object of analysis are the wind turbines with a vertical axis of rotat... see more

In this paper, the efficiency of the vertical-axial wind power plant   at various wind speeds depending on the angle of attack of the rotor blades was investigated. The object of the investigation was a three-bladed Darrieus rotor. During the mo... see more
