Abstract: A wind turbine blade including a shell structure defining a leading edge and a trailing edge, and an upwind shell and a downwind shell joined along at least one of the leading edge or the trailing edge. The shell structure includes an assembly of preformed parts processed into a collection of prefabricated laminates. The invention also includes a method of manufacturing a wind turbine blade, the method includes processing a number of preformed parts into a collection of prefabricated laminates and assembling the collection of prefabricated laminates to build a shell structure defining a leading edge and a trailing edge.

Abstract: A wind turbine blade comprising a fairing with a rigid structural component (12) which forms the majority of the aerodynamic profile and a non-actively controllable elastically deformable trailing edge component (14) mounted on the structural component to complete the aerodynamic profile. The trailing edge component (14) is formed from a material having an elastic modulus in the range of 0.5 to 2.5 GPa such it will elastically buckle when loading on the trailing edge component exceeds a predetermined threshold. The structural component (12) comprises a unidirectional reinforcing layer adjacent to the trailing edge component with at least one layer of unidirectional fibers (26) extending in a substantially spanwise direction.

Abstract: A system and method for manufacturing a wind turbine blade. The wind turbine blade includes a shell structure defining a leading edge and a trailing edge. The wind turbine blade also includes a longitudinal edge extension arranged to extend at least partially along the leading edge or at least partially along the trailing edge to modify an aerodynamic characteristic of the wind turbine blade. The longitudinal edge extension includes a center section and a peripheral section comprising attachment means, and the shell structure is arranged to engage with the attachment means to secure the longitudinal edge extension.

Abstract: A method of forming a structural connection between a spar cap 14 and an aerodynamic fairing 12. A composite comprising an uncured matrix and a compressible solid is applied between the spar cap and fairing and is then compressed and cured to adhere the fairing to the spar cap. The cured matrix composite has a void volume of at least 20%. The high void volume means that as the fairing is compressed into place and compresses the composite, it has space in which to deform so as not to place undue stress on the fairing and to produce a lightweight connection.
