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.

Abstract: A flange connection for two tower sections of a wind energy system is described. The wind energy system includes a first flange including a first portion and a second portion, and a second flange including a first portion and a second portion. The wind energy system further includes a first connecting element having substantially the shape of at least a segment of a ring and a second connecting element having substantially the shape of at least a segment of a ring. The first connecting element and the second connecting element are adapted for being connected to each other and are adapted for connecting the first portion of the first flange with the first portion of the second flange.
