The invention relates to a rotor blade of a wind power plant having two rotor blade half-shells (1, 21) with in each case a leading-edge periphery and a trailing-edge periphery (822), which rotor blade half-shells are adhesively fastened to each other along the leading-edge and trailing-edge peripheries (822) and which in case have a trailing-edge girder (3, 25), and each of the trailing-edge girders (3, 25) at least in certain sections is of rectangular design in a cross section along its longitudinal extent.

Trailing-edge girder with rectangular cross section

An apparatus and method for producing a rotor blade spar cap for a rotor blade of a wind turbine. The apparatus includes a mold, which has a cavity-like depression in cross section, in which material for a rotor blade spar cap can be placed, and a sheet-like mold covering for sealing off the depression. The depression has side walls, an opening bounded by the side walls and a base area between the side walls. In accordance with the method, fiber material and/or fiber-reinforced material is placed in the depression of the mold such that the material finishes flush with the side walls with respect to the height of the rotor blade spar cap, the depression is sealed off by the sheet-like mold covering, the material is fused together to form the rotor blade spar cap and the rotor blade spar cap is removed from the mold.

Apparatus and method for producing a rotor blade spar cap

A method and manufacturing unit for producing a rotor blade () of a wind turbine () from at least a first rotor blade element (') and a second rotor blade element (&#x2032;). The first rotor blade element (&#x2032;) and the second rotor blade element (&#x2032;) are positioned in the desired relative arrangement with respect to each other such that a joint gap () remains between the first rotor blade element (&#x2032;) and the second rotor blade element (&#x2032;). Adhesive is introduced into the joint gap () for joining the first rotor blade element (&#x2032;) and the second rotor blade element (&#x2032;).

Manufacture of a rotor blade for a wind turbine

The invention relates to a system and to a method for producing a rotor-blade spar cap with pultruded rods made of a fiber-reinforced material. According to the invention, the system includes at least one retaining apparatus for rotatably mounting at least one rod-layer roll with a rolled-up layer of pultruded rods arranged one beside the other, and a laminating mold for receiving layers of pultruded rods. The system further includes at least one guiding apparatus and additionally at least one trimming apparatus. The guiding apparatus is designed to guide onto the laminating mold a layer of pultruded rods which has been unrolled from a rod-layer roll. And, the trimming apparatus, for trimming the layers of pultruded rods, has a sawing apparatus and/or a milling apparatus.
