FIELD: wind-power engineering. SUBSTANCE: windmill is made in the form of rotor shaft 1 carrying spiral blades 2 and installed in inclined position to horizontal plane. It develops maximum power when rotor angle of inclination to horizontal plane is smaller than angle of inclination of helical line of blades to rotor axis by angle found from formula 
, where n is rotor speed; H is blade helical line pitch; vwind- is wind speed; k is coefficient of proportionality. EFFECT: improved windmill power capacity. 3 dwg
