Abstract

The invention relates to a rotor blade for a wind energy plant, comprising two shell halves running in th longitudinal direction of th rotor blade from a blade root to the blade tip, connected to each other along the circumference thereof and at least one web device arranged between the shell halves and connected thereto, wherein the web device has two web elements each having two web legs and each a transverse connection between two web legs, wherein for each web element the end of the web legs are connected to just one shell half and the transverse connections of the web elements are connected to each other.
