Abstract
An insert (10) for a wind turbine blade root has a wedge-like portion (16), the wedge-like portion (16) is elongate and extends between a distal end (14) and a proximal end (25) thereof. The wedge-like portion (16) has opposed major surfaces (24, 26) and a connection portion (12) for fitting the insert (10) to a mount, and increases in thickness between the opposed major surfaces (24, 26) in a direction from the distal end (14) to the proximal end (25). The connection portion (12) is integral with, and located at the proximal end (25) of the wedge-like portion (16). With this insert, the total weight of the assembled blade and raw material cost can be reduced considerably, and the manufacturing of the wind blade root including a plurality of such inserts is facilitated.
