Abstract: The present disclosure provides a blade for a wind turbine, where the blade extends in a lengthwise direction between a root end and a tip end of the blade. The blade comprises a leeward shell portion and a windward shell portion, each of the shell portions defining respective inner and outer surfaces extending in a chordwise direction between a leading edge of the blade and a trailing edge of the blade. The blade further comprises a first windward reinforcement structure, a first leeward reinforcement structure, a second windward reinforcement structure, and a second leeward reinforcement structure, the reinforcement structures being arranged internally within the blade and extending in the lengthwise direction of the blade. The second windward and second leeward reinforcement structures are arranged closer to the trailing edge than the first windward reinforcement structure and the first leeward reinforcement structure, respectively, and the second windward reinforcement structure is longer than the second leeward reinforcement structure in the lengthwise direction.

Abstract: The present disclosure provides a blade for a wind turbine, where the blade extends in a lengthwise direction between a root end and a tip end of the blade. The blade comprises a leeward shell portion and a windward shell portion, each extending in a chordwise direction between a leading edge of the blade and a trailing edge of the blade. A first windward reinforcement structure and a first leeward reinforcement structure are arranged internally within the blade and engage the windward and the leeward shell portion, respectively. The first windward and first leeward reinforcement structures extend in the lengthwise direction of the blade and have a thickness in the thickness direction of the blade. The respective thicknesses of the first leeward reinforcement structure and the first windward reinforcement structure decrease towards the tip end in the lengthwise direction in a first section of the blade; and at at least one position along the length of the blade, the decrease of the thickness of the first leeward reinforcement structure is staggered with respect to the decrease of the thickness of the first windward reinforcement structure.

Abstract: A wind turbine blade having a length of at least 100 meters comprising: a root end (and a tip end, the blade extending in a spanwise direction from the root end to the tip end, the root end having a substantially circular profile with a root end diameter, and a profile of the blade transitioning into a lift generating profile moving in the spanwise direction from the root end towards the tip end; a leading edge and a trailing edge, the blade extending in a chordwise direction along a chord from the leading edge to the trailing edge; an inboard region extending in the spanwise direction from the root end to a distal end, the inboard region having a length defined between the root end and the distal end; wherein in the inboard region, the chord of the blade is within 5% of the root end diameter and the inboard region has a length of at least 10% span of the blade.

Abstract: A wind turbine rotor blade having a blade shell with a generally chordwise layup of fibre plies and a generally spanwise spar cap. A lightning conductor extends over the spar cap, and the spar cap includes conductive material. An equipotential bonding element electrically bonds the lightning conductor to the spar cap. The equipotential bonding element extends between an outboard edge of one stack of the fibre plies and an inboard edge of an adjacent stack of the fibre plies, which overlap to define an overlapping edge region.
