Abstract: A wind turbine blade includes: an aerodynamic shell body with a suction side shell part and a pressure side shell part that extends in a longitudinal direction between a root and a tip and in a transverse direction between a leading edge and a trailing edge, and a de-icing system. The de-icing system includes: a number of heating layers each having electrically conductive fibres extending substantially in the longitudinal direction of the wind turbine blade along a longitudinal section of the aerodynamic shell body to provide resistive heating to the longitudinal section of the aerodynamic shell body; a number of metallic patches including a first metallic patch, the number of metallic patches being arranged to contact at least the number of heating layers; and a conductor cable that is electrically connected to the number of metallic patches and further is configured for electrically connecting to a power source.

Abstract: The present invention relates to a measuring device for characterising a shape of a surface of an item, such as a wind turbine blade fibre layup, wherein the measuring device comprises: a frame comprising a holding frame, a first set of two or more probes movably held in the holding frame, each probe having a respective probe end for contacting the surface of the item, and electronic sensing means configured to provide for each probe a respective electrical signal representative of a position of the probe relative to the holding frame. A method for calibrating such a device is provided. Further, a method for characterising a shape of a surface of an item is provided.
