Abstract
Within the field of wind turbine generators (WTG), to provide a consistent way of manufacturing a WT blade there is disclosed a blade mould and a blade spar fixture to support the spar in the mould so as to provide a fixed predetermined relative position, and preferably also orientation, between at least a root end, such as a bushing in the root end of the blade spar, and a root end of the mould. Overall consistency is also obtained in that hereby a blade with anticipated aerodynamic and strength characteristics is provided, among others in that at least adjacent to the root of the spar there is substantially the same distance for a cured adhesive between an innermost surface of each of blade shells and an outermost surface of the spar.
