Abstract: A horizontal axis wind turbine comprising a rotor having a plurality of blades, the rotor having a radius of at least 80 meters, the blades comprising: a root end and a tip end; a leading edge and a trailing edge; a shoulder between the root end and the tip end where a chord length defined between the leading edge and the trailing edge is at a maximum; wherein: Solr is at least 0.0140 at 0.7R; Solr is at least 0.0116 at 0.8R; Solr is at least 0.0090 at 0.9R; Solr being the combined radius specific solidity of the blades.

Abstract: A device for attaching to a surface of a wind turbine blade is described. The device comprises a plurality of sections to be arranged end-to-end along a portion of the blade. Each section of the device comprises: a baseplate for bonding to the surface of the blade; a first panel extending from the baseplate; first and second end walls extending respectively along transverse edges of the baseplate and the first panel; a first tab extending from the first end wall; and a second tab extending from the second end wall, the second tab being transversely offset from the first tab. The tabs are arranged such that when the sections are positioned end-to-end with a first end wall of a first section adjacent to a second end wall of a second section, the first tab of the first section overlaps the second end wall of the second section, whilst the second tab of the second section overlaps the first end wall of the first section. An associated method of mounting the device is also described, which avoids the risk of compromising adhesive and/or sealant during the mounting process.

Abstract: A horizontal axis wind turbine comprising a rotor having a plurality of blades, the rotor having a radius R of at least 80 meters, the blades comprising: a root end and a tip end, the blades extending in a spanwise direction from the root end to the tip end; a leading edge and a trailing edge, the blades extending in a chordwise direction along a chord from the leading edge to the trailing edge; a shoulder between the root end and the tip end where a chord length defined between the leading edge and the trailing edge is at a maximum; the blades being twisted between the root end and the tip end and the twist is defined by a twist distribution curve along the spanwise direction of the blades, each blade further comprising: an inboard region between the root end of the blade and the shoulder of the blade; an outboard region between a rotor radius 0.9R and the tip end of the blade; and a mid-board region located between the inboard region and the outboard region; a noise reduction feature in the mid-board region of the blade, the noise reduction feature projecting from the trailing edge and extending from a first radial position R1 toward the tip end; wherein the twist distribution curve comprises a first inflection point in the vicinity of the first radial position R1.
