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.

A method of producing a single assembled longitudinally extending fibre layer for use in a later resin infusion process for manufacturing a fibre-reinforced composite structure is described including steps: a) providing a first fibre mat comprising unidirectional reinforcement fibres oriented in a longitudinal direction of the first fibre mat, b) providing a second fibre mat comprising unidirectional reinforcement fibres oriented in a longitudinal direction of the second fibre mat, c) arranging the first fibre mat and the second fibre mat so that unidirectional fibres of one end of the first fibre mat adjoin one end of the second fibre mat in a single plane at a common boundary, and d) splicing unidirectional fibres of the first fibre mat at one end of the first fibre mat to unidirectional fibres of the second fibre mat at one end of the second fibre mat in order to form a splicing joint.

A wind turbine blade is described wherein at least one stall fence is provided on the blade surface, where the stall fence is arranged such that it extends at an angle to the chord of the blade. The stall fence acts to re-direct airflow over the blade, to improve wind turbine performance. The stall fence may be a provided towards the blade root end, acting to divert airflow towards the root end of the blade to prevent separation of attached airflow. Additionally or alternatively, the stall fence may be arranged as a flow diverter provided towards the blade tip end, to increase airflow in the tip region for increased performance and/or to disrupt the formation of tip vortices.
