FIELD: wind power engineering.
SUBSTANCE: invention relates to windwheels of wind power and wind electric generating plants with horizontal axle of rotation designed for operation with segment-type electric generators. According to invention, blades are made in form of enveloped double-layer isosceles triangle clamped over perimeter whose vertex is secured at hub and base is furnished with tension plate hinge-connected with balancer hinge-mounted on outer end of tubular sidemember and connected with tensioning tie-rod.
EFFECT: simplified design, improved reliability and manufacturability at provision of modular outline and reduced cost.
