Abstract:
A wind turbine blade comprising a plurality of spar components extending along the longitudinal axis and providing the main bending stiffness of the wind turbine blade a major principal axis defining a structural pitch angle of at least 1° with respect to a chord line, and including: one or more suction-side spar caps each having a centre line; one or more pressure-side spar caps each having a centre line; and one or more shear webs distributed around a central shear web line and at least one of which being connected to first spar caps, wherein at least one suction-side spar cap centre lines is arranged with a first chordwise distance to the central shear web line, and at least one pressure-side spar cap centre lines is arranged with a second, different, chordwise distance to the central shear web line.
