Description
Die Erfindung bezieht sich auf einen Leitschaufelkranz für thermische Strömungsmaschinen, insbesondere Flugtriebwerke, mit an den radial äußeren Leitschaufelfüßen der Leitschaufeln angebrachten, abgewinkelten Haken zum Einführen in zugeordnete Ausnehmungen von Gehäuseteilen.The The invention relates to a vane ring for thermal turbomachines, in particular aircraft engines, with at the radially outer vanes feet the guide vanes attached, angled hooks for insertion in associated recesses of housing parts.
Bei Hochdruckverdichtern bekannter Flugtriebwerke dieser Art ist an den radial äußeren Leitschaufelfüßen seitlich in axialer Richtung je ein abgewinkelter Haken angebracht, mit denen die Leitschaufelfüße in zugeordnete, umlaufende Ausnehmungen axial gegenüberliegender Gehäuseteile eingeführt werden. Diese Ausnehmungen, auch T-Slots genannt, erlauben es – auch bei Einhaltung vorgegebener Toleranzen bei der Fertigung der Ausnehmungen und der Haken – den einzelnen Leitschaufeln, sich beim Anfahren und im Betrieb aufgrund von durch die Anströmung erzeugten Schwingungen leicht zu verdrehen. Dadurch verändert sich der Anströmwinkel der Leitschaufelblätter derart, dass Wirkungsgrad- bzw. Pumpgrenzverluste entstehen. Dabei sind die Leitschaufelblätter an ihren radial innenliegenden Schaufelblattenden frei gegenüber der die Laufschaufeln tragenden Triebwerkswelle angeordnet.at High-pressure compressors known aircraft engines of this type is on the radially outer vanes feet each side angled hook attached in the axial direction, with which the vane feet are assigned in, circumferential recesses of axially opposite housing parts be introduced. These recesses, also called T-slots, allow it - even if given tolerances in the production of the recesses and the hook - the individual vanes, during startup and operation due to of vibrations generated by the flow easily to twist. As a result, the angle of attack changes the guide vanes such that efficiency or Pump limit losses arise. Here are the guide vanes at their radially inner airfoil ends free opposite arranged the blades supporting the engine shaft.
Zur Vermeidung dieser Nachteile ist es bekannt, die Leitschaufelfüße gruppenweise zu verschweißen oder zu verlöten, wobei zwei bis zwanzig Leitschaufeln zu einem Cluster verbunden werden. Das Verschweißen oder Verlöten ist sehr teuer und aufwendig. Außerdem ergibt sich ein Schweißverzug, und die Schweißnähte unterliegen der Gefahr von Rissen bei der hohen thermischen und dynamischen Beanspruchung der Leitschaufelkränze.to To avoid these disadvantages, it is known the vane feet to be welded or soldered in groups, with two to twenty vanes connected to a cluster become. The welding or soldering is very expensive and expensive. In addition, there is a welding distortion, and the welds are at risk of Cracks at the high thermal and dynamic stress of the Vane rings.
Es
ist bei einer gattungsfremden Leitschaufelanordnung nach
Der Erfindung liegt die Aufgabe zugrunde, den Leitschaufelkranz für thermische Strömungsmaschinen, insbesondere bei Hochdruckverdichtern von Flugtriebwerken, dahingehend zu verbessern, dass auch bei unabhängig voneinander in die Ausnehmungen der Gehäuseteile eingeführten Haken der Leitschaufelfüße ein Verdrehen der Leitschaufeln weitgehend verhindert ist.Of the Invention is based on the object, the vane ring for thermal turbomachines, especially in high-pressure compressors of aircraft engines, to the effect that even at independent introduced from each other in the recesses of the housing parts Hook of the vane feet twisting of the vanes largely is prevented.
Diese Aufgabe wird erfindungsgemäß durch ein die radial äußeren Leitschaufelfüße umspannendes Ringelement gelöst. Dieses umspannt die Leitschaufelfüße auf ihren radial äußeren Flächen und verbindet die einzeln, mit ihren Haken in die Ausnehmungen der Gehäuseteile eingeführten Leitschaufelfüße derart, dass ein Kippeln bzw. Verdrehen der Leitschaufeln um ihre Längsachse bzw. deren in die Ausnehmungen der Gehäuseteile eingebrachter Haken der Leitschaufelfüße weitgehend verhindert ist.These The object is achieved by a radially outer Guide vane feet spanning ring element solved. This spans the vane feet onto hers radially outer surfaces and connects individually, with their hooks in the recesses of the housing parts inserted guide vane feet such, that tilting or twisting of the vanes about their longitudinal axis or their inserted into the recesses of the housing parts Hook of Leitschaufelfüße largely prevented is.
Das metallische Ringelement ist in weiterer Ausbildung der Erfindung aus federelastischem metallischem Material gebildet und nicht geschlossen, sondern in noch weiterer Ausbildung der Erfindung mit einem Querschlitz versehen. Dieser unterteilt das Ringelement in Umfangsrichtung, so dass dieses bei der Montage des Leitschaufelkranzes leicht um die Leitschaufelfüße herumgelegt werden kann.The Metallic ring element is in a further embodiment of the invention Made of resilient metallic material and not closed, but in still another embodiment of the invention with a transverse slot Mistake. This subdivides the ring element in the circumferential direction, so that this slightly during assembly of the vane ring the vane feet can be put around.
Das metallische Ringelement kann auch in einer alternativen Ausführungsform aus mindestens zwei miteinander fest verbundenen Kreissegmenten gebildet sein.The Metallic ring element may also be in an alternative embodiment formed from at least two firmly connected circle segments be.
In weiterer Ausbildung der Erfindung sind die radial äußeren Flächen der Leitschaufelfüße mit Nuten zum Einlegen des metallischen Ringelementes versehen. Diese einzelnen Nuten in jedem Leitschaufelfuß bilden bei der Montage des Leitschaufelkranzes eine um diesen auf der radial außen liegenden Fläche der Leitschaufelfüße umlaufende Ringnut, in welche das metallische Ringelement eingesetzt wird. Die Nuten sind seitlich nahe den Haken zum Einführen in die Ausnehmungen der Gehäuseteile angeordnet. Durch Einbringen des metallischen Ringelementes in die umlaufende Ringnut kann der axiale Spalt zwischen den einzelnen Nuten bzw. der Ringnut und dem Ringelement sehr klein gewählt werden, da das metallische Ringelement und die einzelnen Nuten mit genauen Toleranzen hergestellt werden können, wodurch die Freiheit der Leitschaufeln gegen ein Kippeln bzw. Verdrehen um ihre Längsachsen verhindert werden kann.In Another embodiment of the invention are the radially outer Surfaces of vane feet with grooves provided for inserting the metallic ring element. These individual Grooves in each vane foot form during assembly of the Vane ring one around this on the radially outside lying surface of the Leitschaufelfüße circumferential annular groove, in which the metallic ring element used becomes. The grooves are laterally near the hook for insertion arranged in the recesses of the housing parts. By Introducing the metallic ring element in the circumferential annular groove can the axial gap between the individual grooves or the annular groove and the ring element are chosen to be very small, since the metallic Ring element and the individual grooves are manufactured with accurate tolerances which allows the freedom of the vanes against a Tipping or twisting about their longitudinal axes can be prevented can.
In noch weiterer Ausbildung der Erfindung sind die seitlich an den Leitschaufelfüßen angebrachten abgewinkelten Haken von metallischen Laschen umgeben, wobei die freien Enden der Laschen die Nuten übergreifen, um das in die Nuten bzw. die Ringnut eingesetzte metallische Ringelement radial von der Außenseite einzuspannen bzw. radial einwärts zu drücken.In Yet another embodiment of the invention are the side of the Guide vane feet attached angled hook surrounded by metallic tabs, with the free ends of the tabs engage over the grooves, into the grooves or the annular groove used metallic ring element radially from the outside clamp in or push radially inwards.
Das metallische Ringelement kann als ein Draht aus einem hitzebeständigen Metall, insbesondere einer Nickellegierung, gebildet sein. Diese besteht insbesondere aus Nimonic 90 oder aus Haynes 25.The metallic ring element can be considered a wire of a heat-resistant Metal, in particular a nickel alloy, be formed. These consists in particular of Nimonic 90 or Haynes 25.
Ein Ausführungsbeispiel des erfindungsgemäßen Leitschaufelkranzes für thermische Strömungsmaschinen wird anhand eines in den Figuren dargestellten Flugtriebwerkes näher erläutert. Es zeigt:One Embodiment of the invention Guide vane ring for thermal turbomachinery is closer by means of an aircraft engine shown in the figures explained. It shows:
