FIELD: wind-power engineering. SUBSTANCE: each windwheel blade which is, essentially, envelope bent to obtain specific profile and welded over thin rear edge is filled with metered portion of frothing powder and heated up to frothing temperature. Special fixture is used for holding external profile of blade in position during envelope welding, filling with powder, and heating. In this way, desired aerodynamic characteristics of windwheel are obtained. EFFECT: reduced mass, improved strength, stability, service life, and resistance to heavy fluctuating winds. 2 cl, 1 dwg
