FIELD: wind-power engineering. SUBSTANCE: windwheel blade has heather with front and pointed rear edges, top and bottom planes. Bottom and top planes are joined with from of part of cylindrical surface or radius r calculated by using formula r=2,744 v2/ω, where r is radius of cylindrical surface, m; 2.774 is square speed factor; v is speed of air particles flowing onto blade, mps; ω is acceleration of air particles, m/sq.s. EFFECT: improved design. 1 dwg
