Abstract
Disclosed is a blade shell section of a wind turbine blade, such as wind turbine blade with a flatback section. The blade shell section extends in a longitudinal direction from a first shell section position to a second shell section position. The blade shell section comprises a first laminate layer forming the outer surface of the blade shell section and a second laminate layer forming the inner surface of the blade shell section. The blade shell section further comprising a first shell section and a corner shell section between the contour shell section and the flatback shell section.

A blade shell section of a wind turbine blade, the blade shell section extending in a longitudinal direction from a first shell section position to a second shell section position, the blade shell section comprising a first laminate layer forming the outer surface of the blade shell section and a second laminate layer forming the inner surface of the blade shell section,
- the blade shell section further comprising:
- a first shell section comprising a first core element having a first primary core surface and a first secondary core surface opposite the first primary core surface, a first primary core lateral face between the first primary core surface and the first secondary core surface and a first secondary core lateral face between the first primary and first secondary core surface laterally spaced from and opposite the first primary core lateral face;
- a second shell section;
- and
- a corner shell section between the first shell section and the second section, the corner shell section comprising a corner core element being an elongated element extending in a longitudinal direction between a first longitudinal end and a second longitudinal end and having:
- a first corner main surface and a second corner main surface opposite the first corner main surface;
- a first corner end face and a second corner end face opposite the first corner end face;
- and
- a first corner lateral face between the first and the second corner main surface and a second corner lateral face between the first and second corner main surface laterally spaced from and opposite the first corner lateral face, the first corner lateral face having a first corner lateral face height, the second corner lateral face having a second corner lateral face height,
- wherein the corner core element and the first core element being arranged such that the first corner lateral face abuts the first secondary core lateral face,
- wherein the second corner main surface has a first radius of curvature at a first position proximate the first longitudinal end,
- wherein the second corner main surface has a second radius of curvature at a second position proximate the second longitudinal end, and
- wherein the first radius of curvature is larger than the second radius of curvature.
