Abstract: A wind turbine blade having a spar cap and a shear web system is described. The spar cap comprises a pultruded strip of fibrous reinforcing material with a first datum feature visible at a surface of the pultruded strip. The shear web system comprises a second datum feature, wherein the first datum feature of the spar cap is aligned with the second datum feature of the shear web system.

Abstract: Improvements relating to wind turbine blade manufacture 5 A method of making a wind turbine blade is described. The method involves providing a blade shell having an inner surface defining a mounting region and positioning a web in the mounting region. One or more web restraining devices are used to secure the position of the web in the mounting region. Each restraining device has a first portion attached to the web and a second portion attached to the inner surface of the blade shell. The 10 restraining devices are configured to prevent movement of the web in a first plane substantially parallel to the mounting region and to permit movement of the web in a second plane substantially perpendicular to the mounting region. The method further comprises moving the web in the second plane away from the mounting region and performing one or more preparatory operations on the mounting region with the web 15 moved away from the mounting region. The web is then repositioned in the mounting region by moving the web in the second plane back towards the mounting region.

Abstract: A method of forming a structural web for a wind turbine blade comprises providing a web member having a web portion and a flange portion extending away from each other, where 5 a heel of substantially curvilinear form is located between the web portion and the flange portion. A planar flange extender comprising a cured composite material is arranged together with the web member with the flange extender positioned adjacent to the flange portion so that a portion of the flange extender projects past the heel and away from the web portion. The flange extender is integrated with the web member in a resin matrix, or 10 with an adhesive, to form the structural web. A structural web and a wind turbine blade comprising the web is disclosed.

Abstract: A method of making and testing a wind turbine blade comprises providing a structural member having a web portion and a flange portion, where the flange portion extends away from the web portion and a curvilinear heel is defined between the web and flange portions. 5 A flange extender is integrated with the flange portion, where a first section of the flange extender overlies the flange portion, and a second section of the flange extender extends past the heel and away from the web portion. The flange extender is bonded to the inner surface of a wind turbine blade shell. Non-destructive test (NDT) equipment is used to assess the integrity of the bond by identifying first and second target surfaces of the 10 structural member. The target surfaces are spaced apart by an intermediate region, corresponding to the location of the heel, where it is not possible to positively identify any surface using NDT techniques. Identification of the two target surfaces indicates a good integrity bond in the intermediate region, whereas identification of only one, or neither, of the target surfaces indicates a poor integrity bond. 15
