    摘要： The invention relates to a wind turbine blade (5) comprising one or more turbulence generating strips (10), where the strips (10) are placed on a surface of the blade (5). The blade (5) is characterized in that at least one joint area (22) of the turbulence generating strips (10) and the surface of the blade (5) are completely or partially covered by sealing means (23). The invention further relates to a pitch controlled wind turbine (1) comprising at least two pitch controlled wind turbine blades (5) and pitch controlling means for pitching the blades (5). The pitch controlled wind turbine (1) is characterized in that the blades (5) comprises one or more turbulence generating strips (10), wherein at least one joint area (22) of the turbulence generating strips (10) and a surface of the blades (5) are completely or partially covered by sealing means (23).

    摘要： A bolt connection assembly 60 is provided that is particularly well-suited for connecting structural members 50 of a lattice tower structure 48 for a wind turbine 40. The bolt connection assembly 60 includes a bolt component 62 having a head 64 and a shaft 66 and a structural bore component 70 having a bore 74 defined therethrough for receipt of the bolt component 62. The shaft 66 includes a knurled surface 72 such that the knurled surface 72 defines an outermost shaft diameter 92. Moreover, the knurled surface 72 includes a plurality of knurls 90, each defining a non-arcuate edge. The bore 74 defines a bore diameter 98, wherein the outermost shaft diameter 92 is greater than the bore diameter 98. In an assembled state of the bolt component 62 and the structural bore component 70, the bolt component 62 may be inserted within the bore 74 such that the knurled surface 72 may be deformed to friction fit within the bore diameter 98.

    摘要： A wind turbine blade comprising a lightning protection system is provided. The lightning protection system comprises a lightning conductor located along a longitudinal portion of the wind turbine blade and is coupled to an electrical ground. A lightning receptor module is arranged on an external surface of the wind turbine blade and electrically coupled to the lightning conductor. An elongate receptor band is installed on the external surface of the wind turbine blade, over the lightning receptor module, and the receptor band is arranged to receive a stroke of lightning and transfer electrical current from the lightning stroke to the lightning conductor through the lightning receptor module. Further, the elongate receptor band comprises a crease in a longitudinal cross-sectional profile of the elongate receptor band.A method of installing a lightning protection system on a wind turbine blade is further provided.

    摘要： A fluid flow modification apparatus (10) has a surface (15), the surface having an edge (65) of length Y over or past which a fluid can flow in use. The edge (65) has a virtual boundary (30) of length X where Y is greater than X. At least a first portion of the apparatus (10) within the virtual boundary (30) comprises an opening (55) and at least a second portion of the apparatus (10) comprises a projection (60) which extends beyond the virtual boundary (30) to provide the edge (65). The edge (65) is multi-scale.
