Abstract

The negative mold is in sections, one (1) for the root, another (2) for the main section (or mainboard) and another (3) for the tip. Alternatively there is one for the root, and another for both main section and tip. They fit together at the joins. Preferred features: Root molds may have differing lengths and/or differing dimensions of connection to a corresponding rotor hub. The root mold joins flush with the aerodynamically-efficient profile extending over the length of the rotor blade. The root mold may be divided into a mold section to suit differing hub fitting sizes, and a mold section for length compensation.

Description

Die Erfindung bezieht sich auf Rotorblätter aus faserverstärkten Kunsthar­ zen, insbesondere Rotorblätter für Windkraftanlagen, und beschreibt eine Vorrichtung zur Herstellung solcher Rotorblätter.The invention relates to rotor blades made of fiber-reinforced synthetic resin zen, in particular rotor blades for wind turbines, and describes a device for the manufacture of such rotor blades.

Aus der DE 27 38 895 ist ein Verfahren zur Herstellung einer zusammengesetzten aero­ dynamischen Rotorblatteinheit bekannt, bei dem, bei getrennter Formierung des verklei­ deten 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 er­ folgt, wo die Rotorblatteinheit ihre endgültige Struktur erhält.DE 27 38 895 describes a method for producing a composite aero dynamic rotor blade unit known, in which, with separate formation of the disg deten tail profile and subsequent insertion of the formed clad Tail profile into a single mating mold together with the spar Hood, the skirting board and the end plate, a final hardening operation follows where the rotor blade unit gets its final structure.

Rotorblätter aus faserverstärkten Kunstharzen werden üblicherweise aus zwei Rotorblatt­ schalen zusammengesetzt, die in einer Negativform laminiert werden. Dabei werden ent­ sprechend der jeweiligen Größe der Rotorblätter Holmelemente eingebaut. Es ist dabei auch bekannt, die Rotorblattschalen wenigstens teilweise mit einem Schaumstoff auszu­ schäumen. Die so ausgebildeten Rotorblattschalen werden durch Verkleben miteinander verbunden (DE 26 11 235 A1; DE 30 14 347 A1).Rotor blades made of fiber-reinforced synthetic resins are usually made of two rotor blades shells assembled, which are laminated in a negative form. This ent spar elements installed according to the respective size of the rotor blades. It is there also known to at least partially fill the rotor blade shells with a foam foam. The rotor blade shells thus formed are glued together connected (DE 26 11 235 A1; DE 30 14 347 A1).

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

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

Aufgabe der Erfindung ist es, kostengünstig Rotorblätter unterschiedlicher Länge mit va­ riablen Anschlüssen und günstigen aerodynamischen Eigenschaften herzustellen.The object of the invention is to provide inexpensive rotor blades of different lengths stable connections and favorable aerodynamic properties.

Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1, vor­ teilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. This object is achieved with the characterizing features of claim 1 partial embodiments of the invention are the subject of the dependent claims.  

Die Erfindung sieht vor, daß entsprechend der gewollten Rotorblattlänge eine mehrteilige Negativform zusammengestellt wird, die aus mindestens einem Formteil für die Wurzel, einem Formteil für das Mainboard und einem Formteil für die Spitze oder einem Form­ teil für die Wurzel und einem gemeinsamen Formteil für das Mainboard und die Spitze besteht, und in dieser zusammengesetzten Negativform die Rotorblattschalen in einem Stück geformt werden.The invention provides that a multi-part according to the desired rotor blade length Negative form is put together, which consists of at least one shaped part for the root, a molding for the mainboard and a molding for the tip or a mold part for the root and a common molded part for the mainboard and the tip exists, and in this composite negative form, the rotor blade shells in one Be molded.

Der besondere technologische Fortschritt dieser technischen Lösung kommt darin zum Ausdruck, daß die Längenveränderung und die Realisierung unterschiedliche Anschluß­ maße an die Rotornaben durch entsprechend ausgeführte Formteile lediglich für die Wurzel möglich werden.This is where the special technological progress of this technical solution comes in Expression that the length change and the realization different connection dimensions to the rotor hubs by correspondingly designed molded parts only for the Root become possible.

Dazu sieht die erfindungsgemäße Vorrichtung in einer vorteilhaften Ausführung vor, daß die Formteile für die Wurzel nicht nur unterschiedliche Längen und/oder unterschiedliche Anschlußmaße für den Anschluß an eine entsprechende Rotornabe aufweisen, sondern jeweils auch über ein der Länge des Rotorblattes angepaßtes aerodynamisch günstiges Profil verfügen.For this purpose, the device according to the invention provides in an advantageous embodiment that the shaped parts for the root are not just different lengths and / or different Have connection dimensions for connection to a corresponding rotor hub, but each also over an aerodynamically favorable adapted to the length of the rotor blade Profile.

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

Diese vorteilhafte Lösung ist noch dadurch optimierbar, daß das Formteil für die Wurzel geteilt ausgeführt werden kann, nämlich in ein Formteil für unterschiedliche Anschluß­ maße an eine entsprechende Rotornabe und ein Formteil für den Längenausgleich. Dabei versteht es sich, daß die Formteile insgesamt an den Übergängen paßfähig sein müssen.This advantageous solution can still be optimized in that the molded part for the root can be divided, namely into a molded part for different connections dimensions to a corresponding rotor hub and a molded part for length compensation. Here it is understood that the molded parts must be fit overall at the transitions.

Die Erfindung schließt natürlich auch die Möglichkeit ein, unterschiedliche Formteile sowohl für die Spitze als auch das Mainbord zu verwenden.Of course, the invention also includes the possibility of different molded parts to use for both the tip and the mainboard.

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

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

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

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

In den Fig. 1-3 ist die Negativform mehrteilig ausgeführt. Sie besteht aus einem Form­ teil 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 un­ terschiedliche 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 verfügen über ein der Länge des Rotorblattes angepaßtes ae­ rodynamisch günstiges Profil. In analoger Weise können die Formteile für die Wurzel 1 unterschiedliche Anschlußmaße für den Anschluß an unterschiedliche Rotornaben auf­ weisen.In FIGS. 1-3, the negative mold is constructed in 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 , whereby the transitions are fit. The molded parts for the root 1 have un different lengths and thus, by combining each with the same molded part for the mainboard 2 and the tip 3 , allow rotor blades to be made in three lengths. The shaped parts of the root 1 have an ae rododynamically favorable profile adapted to the length of the rotor blade. In an analogous manner, the molded parts for the root 1 can have different connection dimensions for connection to different rotor hubs.
