A WIND TURBINE BLADE COMPRISING AN AERODYNAMIC BLADE SHELL WITH RECESS AND PRE-MANUFACTURED SPAR CAP

摘要

A wind turbine blade has a load carrying structure including at least a first spar cap and an aerodynamic shell having an outer surface forming at least part of an exterior surface of the wind turbine blade and an inner surface. The aerodynamic shell includes a first recess at the inner surface of the blade shell with a first thickened part at a first side of the first recess and a second thickened part at a second side of the first recess. The first recess is tapered towards the first side of the recess and tapered towards the second side of the recess, and the first spar cap is arranged in the first recess of the aerodynamic shell. The first spar cap is tapered towards a first side of the spar cap and further is tapered towards a second side of the spar cap.
