Abstract

A method for manufacturing a rotor blade of a wind power plant which has an area close to the blade root in which the rotor blade has an obtuse rear edge. The method includes manufacturing a half-shell on the pressure side and a half-shell on the suction side, introducing and adhesively bonding filler bodies into at least one section of the area of the obtuse rear edge of the pressure-side half-shell and the suction-side half-shell, wherein the sections with the filler bodies lie opposite one another in the assembled rotor blade, assembling and positioning the half-shells relative to one another, wherein an adhesive gap which is delimited by the first adhesive surfaces of the filler bodies remains between the filler bodies, and introducing an adhesive medium into the adhesive gap. Also a rotor blade manufactured according to the method, and a wind power plant including such a rotor blade.
