LM Wind Power A/S

The present disclosure relates to a production line (5) for manufacturing a wind turbine blade (11). The production line (5) comprises a first workstation (61) configured for carrying out a post moulding manufacturing step on an assembled blade (10) when the assembled blade (10) passes along the first workstation (61) while being conveyed in a first direction (D1) that is substantially aligned with a longitudinal axis of the assembled blade (10). The first workstation (61) extends over a length in a direction that is substantially parallel to the first direction (D1). The length of the first workstation (61) is less than a longitudinal length of the assembled blade (10). The production line (5) also comprises a conveyor system (70) configured for conveying the assembled blade (10) in the first direction (D1). The present disclosure also relates to a method for carrying out a post moulding manufacturing step on an assembled wind turbine blade (10).

The present disclosure relates to a wind turbine blade comprising a leading-edge heating element extending along at least a portion of the leading edge of the wind turbine blade, the leading-edge heating element being configured for deicing a corresponding portion of an exterior surface of the leading edge; a first plurality of heating strips, each heating strip of the first plurality of heating strips extending in a substantially spanwise direction of the wind turbine blade, the first plurality of heating strips forming part of a first shell portion of the wind turbine blade, wherein the first shell portion is the pressure side shell portion or the suction side shell portion, the first plurality of heating strips being spaced apart from one another and from the leading-edge heating strip in a chordwise direction, each heating strip having a first end and a second end, the first end being closer to the tip end than the second end, each heating strip comprising carbon-fibre yarn and/or tow material; and a power source configured to provide electrical power to each of the first plurality of heating strips in order to generate heating in said each strip, said heating being generated by the carbon-fibre yarn and/or tow material. A method for manufacturing the wind turbine blade and a method of deicing such a wind turbine blade are also provided. Further, a heating strip is provided.

A method of masking a mould (40) for moulding a wind turbine blade shell part (24, 26), the method comprising the steps of: arranging a masking device (50) in a mould (40) so that the masking device (50) covers the non-coating zone (46) of the mould surface (41), spraying a coating (70) onto a mould surface of the mould so that the coating is applied to a coating zone (44) of the mould surface (41) and prevented from being applied to a non-coating zone (46) of the mould surface (41) by the arrangement of the masking device (50), and removing the masking device (50) from the mould so that the non-coating zone (46) is exposed. The masking device (50) is configured so that, upon terminating spraying of the coating (70) at the first longitudinal boundary (45) of the coating zone (44), a lip portion (52) of the masking device (50) is separated from the coating (70) applied on the coating zone (44) by a gap (G).

Leading edge protectors for a wind turbine blade are disclosed. The leading edge protectors are configured to at least partially cover a blade leading edge section. The leading edge protectors comprise a main body having a substantially constant thickness and having a trailing end. The leading edge protectors further comprise a plurality of irregularities arranged on an outer surface of the main body upstream from the trailing end and configured to energize a boundary layer. Wind turbines comprising such leading edge protectors are also disclosed.
