FIELD: power engineering.
SUBSTANCE: group of inventions relates to a winding core for making ends of rotor blades of wind-driven power plants and a mold for making segments of rear edges, a method of making a blade end, method of making a segment of trailing edge and method of making rotor blade, as well as a rotor blade and a set of rotor blades. Winding core (100) comprises first section (110) with first end (111) for forming connection with hub intended for connection of blade end to rotor hub, and second section (120) with second end (122) to form connection with outer blade, intended for connection of blade end to outer blade. By replacement or complete or partial removal of first portion of winding core length and/or diameter of first portion, and/or the shape of the first portion can be varied such that the ends of the blades made therefrom are suitable for wind-driven power plants with different rotor diameters. Form for making segments of rear edges for rotor blades of wind-driven power plants, in particular for ends of rotor blades of wind-driven power plants, characterized in that by replacing and/or removing, and/or adding one or more segments of the mold, the lengthwise length of the mold and/or the shape of the mold, and/or the maximum length of the mold perpendicular to the longitudinal length can be varied so that segments of the trailing edge for rotor blades made with its help are suitable for wind-driven power plants with different rotor diameters.
EFFECT: production of rotors with long rotor blades with preset aerodynamics and allowable loads.
