A wind power installation rotary connection, in particular a blade bearing or azimuth rotary connection, wherein the rotary connection is in the form of a plain bearing assembly, comprising an inner ring having a number of first plain bearing surfaces, an outer ring having a number of second plain bearing surfaces which are respectively associated with one of the first plain bearing surfaces as a plain bearing surface partner, and wherein the plain bearing assembly is in the form of a dry-running plain bearing assembly.

A segmented blade, which includes a first blade segment having a first main beam, wherein the first main beam includes a first body portion disposed within the first blade segment and a first engaging portion extending from an end portion of the first body portion toward a direction which is away from the blade root; a second blade segment having a second main beam, wherein the second main beam includes a second body portion disposed within the second blade segment and a second engaging portion extending from an end portion of the second body portion toward a direction which approaches the blade root, and the second engaging portion being engaged in the first engaging portion; and an outer skin, which covers a gap between the first blade segment and the second blade segment. Also provided are a method for connecting segmented blades and a wind power generator set.

The present disclosure is directed to a method for forming a wind turbine rotor blade. The method includes placing first and second prefabricated skin panels defining a portion of a root section of the wind turbine rotor blade, a pressure side of the wind turbine rotor blade, or a suction side of the wind turbine rotor blade in a mold. The first and second prefabricated skin panels partially overlap to define a connection region. A vacuum bag is placed over the mold. The connection region is infused with a resin.

A jointed wind turbine rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint line. Each of the first and second blade segments includes opposite spar caps. The first and second blade segments are connected at the chord-wise joint line by internal joint structure, wherein the joint structure is bonded to the opposite spar caps in at least the second blade segment. The spar caps in the second blade segment have a first section with a first chord-wise width that is unbonded to the joint structure and a second section with a second chord-wise width that is bonded to the joint structure. The second chord-wise width is greater than the first chord-wise width.

The present invention discloses a helicopter hoisting platform for a wind turbine nacelle cover, the helicopter hoisting platform comprising a composite layer and a plurality of metal plates arranged on the outer surface of the composite layer, wherein the plurality of metal plates forms a conductive network electrically connected to a ground connection.

Provided is a wind turbine blade for a wind turbine, the wind turbine blade including: a first element containing carbon fibers, the first element being enclosed by a first metallic cover so as to form a Faraday cage around the same; a second element containing carbon fibers, the second element being enclosed by a second metallic cover so as to form a Faraday cage around the same; and an electrical bond connecting the first metallic cover and the second metallic cover. Elements containing carbon fibers are protected against lightning strikes allowing that such elements are placed further towards the tip, thereby making the whole blade lighter and allowing to better tailor the shape of the tip.

The present invention relates to wind turbine blade and a method of manufacturing the wind turbine blade. An aerodynamic shell is provided with a recess (70) at its inner surface, the recess (70) extending with-in the shell along a spanwise direction of the blade. A first region of the recess (70) has a first width and a second region of the recess (70) has a second width exceeding the first width. A transition region is provided between the first region and the second region of the re-cess. A first and a second spar cap (80, 82) are arranged within the shell.

A wind turbine blade comprising an electro-thermal heating element with a tapering width. The electro-thermal heating element comprises: electrically resistive sheet material; a first electrode which is in electrical contact with the sheet material and positioned at a first end of the element; and a second electrode which is in electrical contact with the sheet material and positioned at a second end of the sheet material. An electrically conductive strip extends across a width of the element. The sheet material has a first part on a first side of the strip and a second part on a second side of the strip. The strip is in electrical contact with the first and second parts of the sheet material. The first part of the sheet material has a first width, and the second part of the sheet material has a second width which is different to the first width.

Provided is a wind turbine blade, with a generally hollow blade body including half shells and webs, with each web including flanges with the first and second webs being supported via respective reinforcement structures relative to the respective half shell, which reinforcement structures are arranged between an outer and an inner layer of the upper and lower half shell of the shells and extend in the lengthwise direction of the blade, wherein the first and second reinforcement structures each include at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in the resin, wherein at least one stiffening element extending parallel to the reinforcement structures over at least a part of their length comprising at least one stack composed of several glass fiber layers infused with resin is arranged between the reinforcement structures.
