This invention relates to wind power engineering, namely to rotary wind motors, which may be used in wind electrical generators or equipment for conversion of wind energy into electrical energy. An object of the present invention is to increase efficiency, power of wind motor and to improve starting acceleration of the rotor. Wind motor comprises rotor (1) with power elements which are realized in the form of two symmetrically arranged blocks (2) and (3) of aerodynamic cascades whereinto each block advantageously consists of four blades (4) realized in the form of a turbine-type configurationof blades. Blocks (2) and (3) of aerodynamic cascade are mounted on central vertical shaft (5). Cascaded blade profiles (4) are in the form of subsonic aerodynamic profiles. Moreover parameters of cascaded blade profiles in turbine-type configuration have the following values: lead of blade - 0.5b; mounting angle of cascade block - 0 degrees; cascaded blade deflection - 0.5b; value of the shading factor - ?0.5; in which: b -value of the chord of blade profile. |
