Definitions
- the invention relates to a method for producing a rotor blade for a wind power plant, which extends in an operative state from a blade root area for connection to a rotor hub of the wind turbine to a blade tip and which is divided into at least two segments for its production.
- Divided or segmented rotor blades for a wind energy plant have been known in principle for the purpose of facilitating their production, transport and installation, for example from DE 31 13 079 A1. Since preferably in the prior art, the transport should be facilitated, the segments of the rotor blade are preferably assembled only at the site of the wind turbine and also designed for it.
- the object of the invention is to facilitate the manufacture of the rotor blade, in particular for series production, and to shorten it in terms of time. - -
- the rotor blade is segmented for its production in more than two segments, that at least for some of these segments separate, temporally parallel to be used manufacturing forms are provided and the segments for finishing the rotor blade outside a Manufacturing mold are connected together to form a rotor blade or rotor blade part.
- a development of the invention also provides that the rotor blade or rotor blade part can also be aftertreated outside of a manufacturing mold, for example can be post-annealed.
- the rotor blade or rotor blade part is finished outside a manufacturing mold, for example, cured, is freed of adhesive residues or resin residues or the like.
- a preferred embodiment of the method according to the invention is characterized in that the segments are manufactured using a plastics technology.
- plastics technology at least one resin and at least one fiber layer, in particular of glass fibers and / or silicone fibers, is used.
- preference is given to using a Resin Transfer Molding (RTM) or an infusion molding (RIM) technique, in particular a vacuum-assisted resin infusion (VAR) technique.
- RTM Resin Transfer Molding
- RIM infusion molding
- VAR vacuum-assisted resin infusion
- a laminating technique can also be used.
- a next development of the invention provides that at least one extending approximately in the longitudinal extent of the rotor blade
- Subdivision is provided for segmenting the rotor blade. This helps to shorten the times of use of the manufacturing forms involved and at the same time does not affect the structure and strength of the finished rotor blade, since still in the production of power conductive and / or transmitting parts and
- Segments can extend continuously over substantially the entire length of the rotor blade. Nevertheless, it is also possible according to the invention to provide, in addition or as an alternative, transverse graduations extending transversely to the longitudinal extent of the rotor blade and to connect the segments formed thereby quickly and reliably without sacrificing quality. - A -
- a development of the invention provides that one or more webs, one or more straps, one or more rotor blade root parts, at least one rotor blade tip segment, shell segments and / or rotor blade shells formed from segments are connected to one another in the connection device.
- segments and / or (other) components can be glued together in the connection device.
- Another development of the invention provides that for heating, tempering, drying and / or curing of components and / or component connections, at least one heating device, preferably in the region of the connection device, is used.
- a next development of the invention is characterized in that first the segments and / or other components are cured or pre-cured, thereafter entered into the connection device, connected there and thereafter the connection and / or the composite of the segments and / or other Components are dried and / or cured, which can also be done with advantage in the connection device without occupancy of a manufacturing mold.
- At least one strap-web assembly can be prefabricated and placed in the connection device for connection to other segments of the rotor blade.
- the strap-web assembly can preferably be created essentially as a box spar, comprising at least two straps and two straps.
- a further development of the invention can provide that a central longitudinal segment of the rotor blade is formed by two subdivisions of the rotor blade extending essentially in the longitudinal extension direction of the rotor biai, which comprises the straps and webs. Additionally or alternatively, it can be provided that the rotor blade is subdivided into at least one leading edge segment and one trailing edge segment by at least one subdivision extending substantially in the longitudinal direction of extension of the rotor blade.
- Protection is claimed, preferably provides that the subdivisions of the rotor blade are provided through through rotor blade root parts, so that, for example. Insert parts for a rotor blade root can be segmented or belong to segments.

- Fig. 4 shows a third embodiment of a segmentation of a rotor blade according to the invention.
- Fig. 1 shows a plan view of a half-shell 1 of a rotor blade.
- the half-shell 1 shown can be divided into several segments 2 to 5. Of these segments 2 to 5, all or some of them can be manufactured or prefabricated essentially parallel to one another over time and then connected in the manner shown in FIG. 1 to form a half-shell 1 of a rotor blade become what can happen in a corresponding connection device.
- the segments 2 to 5 can be glued together, for example.
- the invention provides that a segment is formed by a so-called rotor blade root 2 and the remaining half-shell is divided into three segments 2 to 4.
- the segments 3 to 5 are designed by cross sections 6 to 8 so that they are about the same size and can be made about the same speed. These segments 3 to 5 could, for example, by a
- Longitudinal division can also be subdivided into even further segments or the shark 1 could, for example, also be subdivided or segmented only by longitudinal divisions.
- about the segments 2 to 5 is preferably an undivided, connecting these segments belt which also serves and especially for transmitting forces when loading a arranged on a wind turbine rotor blade.
- a belt may optionally be provided two or more mutually substantially parallel, at a distance from each other running belts, so for example, a so-called leading edge belt and a Schukantengurt, based on the edges of the rotor blade, to which they are respectively closer.
- a complete rotor blade is formed, for example, as a hollow body that on a half-shell 1, a second, mirror-inverted half-shell 1 is placed and the two half-shells 1 are connected together.
- hot air can be introduced to further temper the rotor blade and cure completely.
- the half shells 1 or their segments are preferably formed by means of a plastic technology, for example by glass fiber and / or carbon fiber layers in a manufacturing form, which dictates the three-dimensional shaping of these segments, inserted or layered and then covered with a vacuum film as a whole. This vacuum film is sealed vacuum-tight around the edges on the mold, for example with rubber-like adhesive lines or double-sided adhesive tapes.
- this vacuum film then forms the flexible counter-mold to the solid manufacturing mold.
- a negative pressure a "vacuum”
- a vacuum is then created by removing air between the vacuum film and the production mold, by means of which vacuum the fiber layers are pressed together and a resin is sucked in from under a vacuum film over a reservoir Evenly distributed throughout the mold and the fiber layers after curing firmly together with one another to form a solid plastic molded part, the respective segment.
- a uniform distribution of the resin can be achieved by several supply lines for the resin are laid and suitable mesh or grid layers in the Form are inserted, which favor the distribution and the surface flow of the resin and guide.

- Fig. 2 shows a first embodiment of a segmentation of a rotor blade according to the invention.
- a central longitudinal segment 11 of the rotor blade which comprises the straps 12 and webs 13, is formed by two subdivisions 9, 10 of the rotor blade extending essentially in the longitudinal direction of extension of the rotor blade.
- at least one leading edge segment 14 and one trailing edge segment 15 are thereby eliminated. forms.
- the subdivisions 9, 10 continue into the rotor blade root 2.
- there are thus essentially three segments 11, 14, 15 which are produced parallel in time, and thus faster, in different production forms and later, outside of any production form, can be connected to form a complete rotor blade, whereby a rotor blade is produced. the qualitatively and in particular with regard to the transmission of forces and load capacity, in no way inferior to a known rotor blade.

- the rotor blade is divided into a lower shell 16 and an upper shell 17.
- these two shells 16, 17 are each further segmented by a longitudinal division 18, 19.
- the subdivisions 18, 19 continue through the rotor blade root 2 and the rotor blade is ultimately substantially quartered.
- the advantages are substantially the same as in the first embodiment shown in FIG. 2.
- the invention can be based on the idea of producing individual segments of a rotor blade which can each be fabricated parallel to one another in their own production molds.
- the part form with the longest cycle time determines the cycle time of the overall process, which can be reduced accordingly with advantage accordingly.
- Skillful segmentation of the sheet permits on the one hand an alignment of the molding times with one another and thereby a high degree of utilization, and on the other hand a reduction of the cycle time, with which the cycle time of the overall process and thus the throughput of the paper can be increased.
