Abstract
Description
Die Erfindung betrifft eine verstellbare Leitschaufel nach dem Oberbegriff des Patentanspruchs 1. Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung einer verstellbaren Leitschaufel nach dem Oberbegriff des Patentanspruchs 8.The The invention relates to an adjustable guide vane according to the preamble of claim 1. Furthermore, the invention relates to a method for the production of an adjustable guide vane according to the generic term of claim 8.
Verstellbare Leitschaufeln werden in Verdichtern, insbesondere in Hochdruckverdichtern, moderner Gasturbinen, insbesondere moderner Flugzeugtriebwerke, eingesetzt, um den Verdichter optimal innerhalb seiner Betriebsgrenzen betreiben zu können.adjustable Guide vanes are used in compressors, especially in high pressure compressors, modern gas turbines, especially modern aircraft engines, used to optimize the compressor within its operating limits to be able to operate.

Zur
Herstellung der aus dem Stand der Technik bekannten Leitschaufeln
wird gemäß der
Nach dem Stand der Technik verfügen die verstellbaren Leitschaufeln demnach über eine Bauweise, bei welcher der Lagerzapfen integraler Bestandteil des Schaufelblatts ist und zur Vorfixierung Fasern der Lagerzapfen mit Fasern des Schaufelblatts von Hand vernäht werden. Auf diese Art und Weise kann zwar eine ausreichende Festigkeit erzielt werden, die Herstellkosten solcher verstellbarer Leitschaufeln sind jedoch durch die erforderlichen Handarbeiten hoch. Auch lässt sich das Herstellverfahren derartiger Leitschaufeln bedingt durch die Handarbeiten nicht automatisieren.To state of the art the adjustable guide vanes therefore have a construction in which the bearing journal is an integral part of the airfoil and for pre-fixing fibers of the trunnion with fibers of the blade sewn by hand become. Sufficient strength can be achieved in this way are achieved, the manufacturing costs of such adjustable guide vanes however, are high due to the required handwork. Also can be the manufacturing process of such guide vanes due to the Do not automate needlework.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, eine neuartige verstellbare Leitschaufel sowie ein Verfahren zur Herstellung derselben vorzuschlagen.Of these, starting from the present invention, the problem is based, a new type of adjustable guide vane and a manufacturing process to propose the same.
Dieses Problem wird dadurch gelöst, dass die eingangs genannte verstellbare Leitschaufel durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 weitergebildet ist.This Problem is solved by that the adjustable guide vane mentioned at the outset by the features of the characterizing part of claim 1 is developed.
Erfindungsgemäß ist der oder jede Lagerzapfen geteilt ausgebildet, und die Fasern des Schaufelblatts sind zwischen Teile der jeweiligen Lagerzapfen geführt und zwischen diesen fixiert.According to the or each trunnion is split, and the fibers of the airfoil are guided between parts of the respective journal and fixed between these.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist der oder jede Lagerzapfen zweiteilig ausgebildet. Die Fasern des Schaufelblatts sind zwischen die beiden Teile des jeweiligen Lagerzapfens geklemmt und zusätzlich durch eine Klebverbindung in dieser Position gesichert.To An advantageous embodiment of the invention is the or each Bearing pin formed in two parts. The fibers of the airfoil are clamped between the two parts of the respective journal and additionally secured in this position by an adhesive connection.
Das erfindungsgemäße Verfahren ist durch die Merkmale des unabhängigen Patentanspruchs 8 gekennzeichnet.The inventive method is characterized by the characteristics of the independent Claim 8 characterized.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den abhängigen Unteransprüchen und der nachfolgenden Beschreibung.preferred Further developments of the invention result from the dependent subclaims and the description below.
Ein Ausführungsbeispiel der Erfindung wird, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert. In der Zeichnung zeigt:On embodiment The invention is, but is not limited to, the drawing explained in more detail. In the drawing shows:

Zur
Herstellung der erfindungsgemäßen Leitschaufel
Alternativ zum oben genannten RTM-Verfahren kann auch ein induktives Schmelzschweißen unter Verwendung langfaserverstärkter Thermoplaste zum Einsatz kommen.alternative Inductive fusion welding can also be used for the above-mentioned RTM process Use of long fiber reinforced Thermoplastics are used.
Die erfindungsgemäße Leitschaufel sowie das erfindungsgemäße Verfahren zur Herstellung der Leitschaufel verfügen über den Vorteil, dass zeitaufwendige und kostenintensive Handbearbeitungsschritte stark reduziert werden können. Das mühsame Vernähen der Fasern der Lagerzapfen mit den Fasern des Schaufelblatts kann entfallen. Hierdurch ergeben sich erhebliche Zeit- und Kostenvorteile bei der Herstellung der erfindungsgemäßen Leitschaufel. Durch das Einklemmen der Fasern im Bereich der Lagerzapfen werden die Fasern optimal vor sogenannter Delamination geschützt. Hierdurch ist es möglich, das volle Festigkeitspotential der Fasern auszunutzen. Die Festigkeit kann demnach gegenüber aus dem Stand der Technik bekannten verstellbaren Leitschaufeln verbessert werden.The guide vane according to the invention and the method according to the invention to manufacture the vane have the advantage of being time consuming and costly manual processing steps are greatly reduced can. The tedious stitch the fibers of the trunnion with the fibers of the airfoil omitted. This results in considerable time and cost advantages in the manufacture of the guide vane according to the invention. By the The fibers become jammed in the area of the bearing journal optimally protected against so-called delamination. This makes it possible to exploit the full strength potential of the fibers. The firmness can therefore face adjustable guide vanes known from the prior art be improved.
