Description

Die Erfindung bezieht sich auf Rotorblätter aus faserverstärkten Kunstharzen, insbesondere Rotorblätter für Windkraftanlagen, und beschreibt eine Vorrichtung zur Herstellung solcher Rotorblätter.The invention relates to rotor blades fiber reinforced Synthetic resins, in particular rotor blades for wind turbines, and describes a device for producing such rotor blades.

Aus der DE 27 38 895 ist ein Verfahren zur Herstellung einer zusammengesetzten aerodynamischen Rotorblatteinheit bekannt, bei dem, bei getrennter Formierung des verkleideten Schwanzprofils und nachfolgendem Einlegen des formierten verkleideten Schwanzprofils in eine einzige Zusammenpaß-Preßform zusammen mit dem Holm, der Haube, der Bugleiste und der Endplatte, ein abschließender Aushärtungsarbeitsgang erfolgt, wo die Rotorblatteinheit ihre endgültige Struktur erhält.From the DE 27 38 895 A method is known for producing a composite aerodynamic rotor blade unit, in which, when the clad tail profile is formed separately and then the formed clad tail profile is inserted into a single mating press mold together with the spar, the hood, the skirting board and the end plate, a final curing step is carried out takes place where the rotor blade unit receives its final structure.

Rotorblätter aus faserverstärkten Kunstharzen werden üblicherweise aus zwei Rotorblattschalen zusammengesetzt, die in einer Negativform laminiert werden. Dabei werden entsprechend der jeweiligen Größe der Rotorblätter Holmelemente eingebaut. Es ist dabei auch bekannt, die Rotorblattschalen wenigstens teilweise mit einem Schaumstoff aus zuschäumen. Die so ausgebildeten Rotorblattschalen werden durch Verkleben miteinander verbunden ( DE 2611235 A1 ; DE 3014347 A1 ).Rotor blades made of fiber-reinforced synthetic resins are usually composed of two rotor blade shells, which are laminated in a negative form. Spar elements are installed according to the respective size of the rotor blades. It is also known to at least partially foam the rotor blade shells with a foam. The rotor blade shells designed in this way are connected to each other by gluing ( DE 2611235 A1 ; DE 3014347 A1 ).

Neben dem Handauflegeverfahren, bei dem mit Kunstharz getränkte Fasermatten schichtweise aufeinander gelegt werden, sind auch Verfahren mit maschinell vorbereiteten oder vorimprägnierten Geweben bekannt ( EP 0 690 228 A1 ).In addition to the hand laying process, in which fiber mats impregnated with synthetic resin are laid on top of each other in layers, processes with machine-prepared or pre-impregnated fabrics are also known ( EP 0 690 228 A1 ).

Ein wesentlicher Nachteil dieser Verfahren besteht darin, dass für jede Rotorblattlänge gesonderte Formen vorhanden sein müssen. Da dies teuer ist, wurden in der Vergangenheit die Rotorblätter im Anschlußbereich durch ein zylindrisches Rohr aus unterschiedlichen Werkstoffen verlängert. Dies wiederum ist aerodynamisch ungünstig.A major disadvantage of this Procedure is that for any rotor blade length separate forms must be available. Since this is expensive, have been in the past the rotor blades in the connection area extended by a cylindrical tube made of different materials. This again, it is aerodynamically unfavorable.

Dem Tagungsband der 3. Deutschen Windenergiekonferenz DEWEK'96, veranstaltet vom Deutschen Windenergieinstitut, ist die Information zu entnehmen, zum Zwecke der Schaffung einer möglichst großen Anzahl verschiedener Variationen eines Grundflügels, For men mit austauschbaren Blattspitzen- und Blattwurzelformteilen herzustellen. Die Variationen werden dahingehend präzisiert, unterschiedliche Längen zu erreichen und bestimmte Materialien einzusetzen.The conference book of the 3rd Germans DEWEK'96 wind energy conference, organized by the German Wind Energy Institute, is the information in order to create as many different variations as possible of a basic wing, Molds with interchangeable leaf tip and root parts manufacture. The variations are clarified different lengths to achieve and use certain materials.

Aufgabe der Erfindung ist es, kostengünstig Rotorblätter unterschiedlicher Länge mit variablen Anschlüssen und günstigen aerodynamischen Eigenschaften herzustellen.The object of the invention is to inexpensively different rotor blades Length with variable connections and cheap to produce aerodynamic properties.

Gelöst wird diese Aufgabe mit den Merkmalen des Anspruchs 1.This task is solved with the Features of claim 1.

Die erfindungsgemäße Vorrichtung zur Herstellung von Rotorblättern, bei der in Negativformen Rotorblattschalen geformt werden, die anschließend zu einem Rotorblatt zusammengefügt werden, wobei die Negativform mehrteilig ausgeführt ist und über mindestens ein Formteil für die Wurzel, ein Formteil für das Mainboard und ein Formteil für die Spitze oder ein Formteil für die Wurzel und ein Formteil für das Mainboard und die Spitze verfügt, die an den Übergängen paßfähig sind, sieht vor, dass die Formteile für die Wurzel über der Länge des Rotorblattes angepaßte aerodynamisch günstige Profile aufweisen. Die Formteile für die Wurzel haben dazu unterschiedliche Längen im Bereich von 8 bis 12 m Wurzellänge und können unterschiedliche Anschlußmaße für den Anschluß an eine entsprechende Rotornabe aufweisen.The manufacturing device according to the invention of rotor blades, in which rotor blade shells are formed in negative molds, which subsequently form put together a rotor blade be, the negative form is made of several parts and at least a molding for the root, a molding for the mainboard and a molding for the tip or a molding for the root and a molding for that Motherboard and the top features that fit at the transitions, provides that the molded parts for the root over the length adapted to the rotor blade aerodynamically favorable Have profiles. The shaped parts for the root have different lengths in the range of 8 to 12 m root length and can have different connection dimensions for connection to a have the appropriate rotor hub.

Auf diese Weise ist es möglich, aerodynamisch optimierte Rotorblätter unterschiedlichster Längen und mit unterschiedlichen Anschlußmaßen an die Rotornabe nur durch den Austausch eines Formteils herzustellen.In this way it is possible to be aerodynamic optimized rotor blades different lengths and with different connection dimensions to the rotor hub only through to replace a molded part.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Es zeigen:An embodiment of the invention is shown in the drawing. Show it:

1: modularer Aufbau der Negativform mit 8 m Wurzellänge, 1 : modular structure of the negative form with 8 m root length,

2: modularer Aufbau der Negativform mit 10 m Wurzellänge und 2 : modular structure of the negative form with 10 m root length and

3: modularer Aufbau der Negativform mit 12 m Wurzellänge. 3 : modular structure of the negative mold with a 12 m root length.

In den 1–3 ist die Negativform mehrteilig ausgeführt. Sie besteht aus einem Formteil für die Wurzel 1, einem Formteil für das Mainboard 2 und einem Formteil für die Spitze 3, wobei die Übergänge paßfähig sind. Die Formteile für die Wurzel 1 haben unterschiedliche Längen und gestatten so durch Kombination jeweils mit dem selben Formteil für das Mainboard 2 und die Spitze 3, Rotorblätter in drei Längen auszuführen. Die Formteile der Wurzel 1 verfugen über ein der Länge des Rotorblattes angepaßtes aerodynamisch günstiges Profil. In analoger Weise können die Formteile für die Wurzel 1 unterschiedliche Anschlußmaße für den Anschluß an unterschiedliche Rotornaben aufweisen.In the 1 - 3 the negative form is made up of several parts. It consists of a molded part for the root 1 , a molded part for the mainboard 2 and a molded part for the tip 3 , where the transitions are fit. The molded parts for the root 1 have different lengths and thus allow by combining the same molded part for the mainboard 2 and the top 3 To produce rotor blades in three lengths. The shaped parts of the root 1 have an aerodynamically favorable profile adapted to the length of the rotor blade. In an analogous way, the molded parts for the root 1 have different connection dimensions for connection to different rotor hubs.
