A rotor blade for a wind turbine having an aerodynamic profile which extends from a blade root up to a blade tip and has a leading edge and a trailing edge. An adjustable aerodynamic flap, which can be adjusted between a retracted and a deployed position by means of a flap drive, is provided on the rotor blade. The flap drive comprises a passive control system which controls a flap position depending on rotation speed. The passive control system of the flap drive is low-maintenance and does not interfere with the safety concept of a wind turbine. In comparison with a reference rotor blade without a flap, the rotor blade has increased lift at low wind speeds.

A wind turbine rotor blade (10) is provided with a lightning protection device (84) and a leading edge member (70), the leading edge member (70) comprising an erosion shield (78, 80), deicing means, and an electrically conductive outer surface (80) which is operatively connected to the lightning protection device (84). The invention also relates to the use of the leading edge member (70) for providing leading edge erosion protection, ice mitigation and lightning protection of a wind turbine rotor blade.

Provided is a rotor blade for a wind turbine, with a trailing edge including a trailing edge core having several core elements arranged side by side, and with an inner and an outer laminate, wherein one core element is split into two element parts separated by a slit, whereby, seen in the direction from a blade root to a blade tip, the inner laminate runs into and through the slit and becomes the outer laminate.

A wave receiving plate is pivotably supported by a support device in the wave force generation system and includes a flexible plate in at least a part of the wave receiving plate.

A rotor blade assembly for a wind turbine includes at least one rotor blade having surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a blade tip and a blade root. The surfaces are constructed of a polymeric composite material. The rotor blade assembly also includes a protection cap arranged adjacent to one or more of the surfaces of the rotor blade so as to cover at least a portion of the one or more surfaces of the rotor blade. The protection cap includes a body defining an overall length. Further, at least a first segment of the protection cap is constructed of a tungsten-based metal. Thus, the protection cap is configured to reduce erosion and resist corrosion of the rotor blade caused by particle or liquid impact.

Compositions and methods for forming epoxy resin systems are provided. In one embodiment, a composition is provided for an epoxy resin system including a liquid epoxy resin component including a liquid epoxy resin and an acrylate monomer, a curing agent component including a compound having an imidazole group and, optionally, a co-curing agent for the compound having an imidazole group comprising a phenolic monomer compound, a branched chain carboxylic acid, and combinations thereof, and a non-aromatic polyol compound. The composition may be used to form composites, such as used in commercial wind turbine blade manufacturing.

A flexible aeroshell extender piece for an inboard part of a wind turbine blade is described, along with an associated method of manufacture. The flexible aeroshell is formed by first assembling a consolidated aeroshell piece, and then making a series of slits at the trailing edge of the aeroshell piece. Such a construction provides an aeroshell having a relatively flexible trailing edge section, which allows for bending or flexing of the aeroshell trailing edge during wind turbine blade operation.

Provided is a leading-edge protector for a wind turbine rotor blade, including a curved body shaped for attachment to the rotor blade along at least a section of its leading edge; a plurality of fins, each fin extending radially outward from the curved body and terminating in a blunt outer face; and a plurality of reinforcement bands, wherein a reinforcement band is attached to the blunt outer face of a fin. Also provided is a method of manufacturing such a leading-edge protector.

Devices, systems, and methods of manufacturing wind turbine root attachment are provided. In various embodiments, an assembly for wind turbine root attachments includes a bushing, a core, and a filler. The bushing includes a body having cutouts extending from the proximal end to the distal end on either side of the bushing and a core cutout at the distal end. The bushing further includes an ear disposed at the proximal end of the bushing and within the first cutout. The core includes two wedges where the thick end of each wedge abut one another. The thin end of the proximal wedge is disposed within the core cutout and the core includes cutouts extending from the proximal end to the distal end on either side of the core. The filler is disposed within the cutout on the side of the assembly having the ear.

Provided is a method for manufacturing segments for a tower, in particular of a wind turbine, and a prestressed segment for a tower. Provided is tower ring for a tower, a tower of the wind turbine, and a wind turbine. In addition, a prestressing device is provided. The method for manufacturing segments for a tower, in particular of a wind turbine, comprises: arranging at least one prestressing element in a mold, wherein the prestressing element comprises or consists of fiber-reinforced plastic; tensioning the prestressing element; embedding the prestressing element in a concrete mass; hardening of the concrete mass into a longitudinal segment, preferably in the form of a complete longitudinal segment of a tower; removing the hardened longitudinal segment from the mold.
