PRE-BENT WIND TURBINE BLADE WITH MULTIPLE INFLECTION POINTS AND METHOD OF MAKING SAME

A wind turbine blade (40) for a wind turbine (10) includes an elongate body (42) defining a root end (44), a tip end (46), a leading edge (56), and a trailing edge (58). The elongate body (42) further defines a pitch axis (60) and a blade centre line axis (64) extending along a length of the blade (40). The blade centre line axis (64) defines a pre-bend in the blade (40), wherein the curve that defines the blade centre line axis (64) includes at least a first inflection point (I₁) and a second inflection point (l₂) between the root end (44) and the tip end (46) of the blade (40). A method of making a wind turbine blade (40) having a blade centre line axis (64) with multiple inflection points is disclosed and a moulding assembly (80) for making the pre-bent wind turbine blade (40) is also disclosed.
