Abstract

Provided is a method of assembling an aerogenerator blade tip segment. The method includes: removing an outboard tip end part of an aerogenerator blade; removing at least a portion of a leading edge panel and at least a portion of a trailing edge panel from a remaining outboard end of the aerogenerator blade, thus forming a body and a projection extending in a substantially longitudinal direction from an outboard end of the body, the projection having a spar cap portion and a shear web portion; removing a coating from an outer surface of the projection; attaching at least one reinforcement to the shear web portion of the projection; bonding a tip segment to the projection; and covering a joint between the body of the aerogenerator blade and the tip segment with an aerodynamic profile.

Description

technical field [0001] The present invention relates to wind turbine blades and, more particularly, to a method for assembling a wind turbine blade tip section and a blade tip section assembly. Background technique [0002] Wind power is often generated by large generators comprising a vertical structure (e.g. a tower) on top of which is placed at least one horizontal or vertical axis wind turbine comprising one, two, three or multiple rotor blades. Wind energy generators (or simply "wind turbines") are designed to harness the wind energy present at a particular location and thus vary in height, control system, number of blades, blade orientation, shape and material. [0003] It is common in commercial wind farms to use blades with a length of 20 to 40 meters for wind turbines having a rated power of about 0.5 MW to about 1.5 MW. However, even larger wind turbine blades, which may have a length greater than 80 meters, are currently being realized. However, intermediate si...
