Wind generator`s blade for producing electricity, has at one of its ends cylindrical root to be fixed with hub of wind generator by screwing units cooperating with threaded bores carried by root

摘要

The blade includes at one of its ends a cylindrical root (1) to be fixed with a hub of an aerogenerator by screwing units cooperating with threaded bores (31) carried by the root or by a unit connected to the root. The threaded bores are extended in a direction of the hub. The threaded bores are kept in a rim (3) that partially leans against the root. Independent claims are also included for the following: (A) a wind generator carrying a blade (B) a method of manufacturing a blade of a wind generator.
