Embodiment Construction

[0032] figure 2 A schematic view of a wind energy installation according to the invention is shown. Wind energy installation 100 has a tower 102 and a pod 104 on tower 102 . An aerodynamic rotor 106 having three rotor blades 200 and a spinner 110 is arranged on the pod 104 . During operation of the wind power plant, aerodynamic rotor 106 is brought into a rotational movement by the wind so that the rotor or armature of a generator, which is directly or indirectly coupled to aerodynamic rotor 106 , is also rotated. An electrical generator is disposed in the pod 104 and generates electrical energy. The pitch angle of the rotor blade 200 can be varied by a pitch motor at the rotor blade root of the respective rotor blade 200 .

[0033] Figure 3A 3D shows different schematic sectional views of a part of a rotor blade 200 according to the invention during the production of the spar cap. exist Figure 3B A schematic sectional view along section A-A is shown in Figure 3C A ...

Abstract

The invention relates to a method for producing a wind turbine rotor blade. A mold (300) for a spar cap (400) is provided. The mold (300) has at least one negative cap edge (310, 320). Glass fiber layers are laid into the mold (300) and in the negative cap edge (310, 320) in order to achieve a transverse bevel at the end of the glass fiber layers such that a spar cap (400) having a negative bevelis provided. The spar cap (400) having the negative bevel is installed into a core material of the rotor blade.

Description

technical field [0001] The invention relates to a method for producing a rotor blade of a wind energy installation. Background technique [0002] figure 1 A schematic cross-section of a rotor blade of a wind energy installation is shown. A rotor blade usually consists of two shells, of which the first shell 10 is the suction side and the second shell 20 is the pressure side. Furthermore, the rotor blades each have a spar 40 on the suction side and a pressure side and a web 30 which connects the spar 40 on the suction side and the pressure side to one another. The flange 40 is here firmly connected to the suction-side and / or pressure-side material. [0003] DE 10 2009 047 570 A1 describes a flange for a wind energy installation and the manufacture of such a flange. The spar caps consist of a plurality of individual layers consisting of glass fiber or carbon fiber fabrics which are placed in the mould. Next, a vacuum film is placed and epoxy resin is poured through the vo...
