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.

IPC: F03D1/06

Abstract: A bulkhead assembly for a wind turbine blade is described, wherein a pressure relief conduit is provided at the bulkhead to allow for pressure to equalise across the bulkhead. This helps to prevent faults or cracks in the bulkhead assembly due to differences in pressure on either side of the bulkhead. Furthermore, liquid traps and/or filter media can be accommodated in the conduit to prevent the passage of liquids or other matter across the bulkhead.

IPC: F03D1/06

Abstract: A wind turbine blade assembly comprising a wind turbine blade having a tip end and a root end, and a leading edge and a trailing edge with a chord length extending therebetween is described. The wind turbine blade assembly further comprises an aeroshell extender piece comprising a body for attachment to a trailing edge side of a profile of a wind turbine blade, the body having a first end for attachment to the trailing edge side of the profile, and a second trailing edge end to form an extended airfoil trailing edge profile for a portion of the profile of the wind turbine blade. The aeroshell extender piece is attached to the wind turbine blade at least partly using at least one profile wedge, said at least one profile wedge being shaped to compensate for the geometry of the wind turbine blade.
