Claim 0:
1. A kit of parts for a plurality of wind turbine blades, comprising a plurality of wind turbine blades or a plurality of wind turbine blade portions each having:
an outer blade shell and a structural support connected to the outer blade shell, wherein the outer blade shell includes an outer blade shell region spaced from the structural support in a chordwise direction, the outer blade shell region including a plurality of composite plies, each ply of the outer blade shell region having a position within the respective outer blade shell of the wind turbine blade or the respective wind turbine blade portion and a fibre orientation angle relative to a pitch axis of the respective outer blade shell of the wind turbine blade or the respective wind turbine blade portion,
wherein each of the wind turbine blades or each of the wind turbine blade portions have substantially the same size and outer geometrical shape and corresponding pitch axes, and
wherein at least one ply of each of the respective outer blade shell regions of the wind turbine blades or the respective outer blade shell of the wind turbine blade portions corresponds, which corresponding plies have the same position within the respective outer blade shell of the wind turbine blades or wind turbine blade portions and have different fibre orientation angles such that the wind turbine blades or wind turbine blade portions have different bend-to-twist couplings.
