Abstract: A wind turbine blade bushing system for arrangement in a root end of a wind turbine blade is described. The wind turbine blade bushing system comprises a threaded element for retaining a mounting bolt for a wind turbine blade, the threaded element being formed from a first material; and an anchor element for arrangement at the root end of the wind turbine, wherein the anchor element acts to at least partly retain the threaded element in the wind turbine blade, the anchor element being formed from a second material. The first material has a higher strength and higher fracture toughness than the second material.

Abstract: A tribrid wind turbine blade is described, wherein the blade is formed from three separate parts made using three different manufacturing approaches. A root section of the blade is formed by a load-bearing central spar having an aerodynamic shell or fairing fitted to the spar. A mainboard portion is formed from a load-bearing shell structure. A tip portion is formed as an integrally-formed element from a one-shot closed moulding process.
