Zusammenfassung:	Method to make a large-size blade of a windmill includes formation of an initial hollow bearing frame with varying cross-section, with use of longerons, with orbital layered laying of reinforcement material soaked with composition and formation of composite shell. Before installation of longerons there are arranged through openings to let the long links-thrusts through those. Besides that, the longerons are installed with possibility of mutual change of placement on the long axis of the frame. Formation of profile of blade is performed by change of air pressure in closed elastic vessels placed inside of the frame between the longerons. The outer surface of those vessels is made segmented, with drop-like bosses.
