A rotor wind turbine with a screen of telescopic type includes a vertical axle, horizontal trusses, hinged fixation and canvas. Additionally the wind turbine is equipped with a screen for control of value of working surface of the canvas that receives wind pressure. The screen is arranged by telescopic type, i.e. it consists of at least two or more in number interrelated movable parts in cylindrical form that can slide one in another. Each of intermediate sections is outer for the previous one, and inner for the following one, each inner section goes in free way to each section that is placed outside. Each of the sections of cylindrical screen of telescopic type is equipped with the upper and the lower flat rings between which a cylinder made of flat material, mostly plastic, is fixed, and each lower ring of each inner section of the cylindrical screen of telescopic type at lift hooks each upper ring of each section of telescopic screen that is placed outside. The rotor wind turbine is additionally equipped with mechanism for lifting/lowering the inner section of telescopic screen, block for automated control of lifting/lowering the inner section of telescopic screen, indicator of frequency of rotation of rotor wind turbine, for instance, tachometer, and cylindrical case for placement of telescopic screen when it is not used. |
