Abstract
Description
Die Erfindung bezieht sich auf eine Fluggasturbinenschubumkehrvorrichtung mit einem Triebwerk, mit einer Triebwerksverkleidung sowie mit mehreren, am Umfangsbereich angeordneten, lageveränderbaren Umlenkelementen.The invention relates to an aircraft gas turbine thrust reverser with an engine, with an engine cowling and with several, arranged on the peripheral region, variable position deflecting elements.
Aus der
Die
Der Erfindung liegt die Aufgabe zugrunde, eine Fluggasturbinenschubumkehrvorrichtung der eingangs genannten Art zu schaffen, welche bei einfachem Aufbau und einfacher, kostengünstiger Herstellbarkeit einen hohen Wirkungsgrad aufweist und für unterschiedliche Geometrien von Fluggasturbinen einsetzbar ist.The invention has for its object to provide an aircraft gas turbine thrust reverser device of the type mentioned above, which has a high efficiency with a simple structure and simple, cost manufacturability and can be used for different geometries of aircraft gas turbines.
Erfindungsgemäß wird die Aufgabe durch die Merkmalskombination des Anspruchs 1 gelöst, die Unteransprüche zeigen weitere vorteilhafte Ausgestaltungen der Erfindung.According to the invention the object is achieved by the combination of features of
Erfindungsgemäß ist somit vorgesehen, dass am Umfangsbereich der Triebwerksverkleidung Umlenkelemente angeordnet sind, welche in Axialrichtung des Triebwerks verschiebbar sind. An dem in Strömungsrichtung hinteren Endbereich der jeweiligen Umlenkelemente sind schwenkbare Türen angeordnet, die beim Verschieben der Umlenkelemente über einen Hebelmechanismus betätigt werden.According to the invention it is thus provided that deflection elements are arranged on the peripheral region of the engine cowling, which are displaceable in the axial direction of the engine. On the rear end region of the respective deflecting elements in the flow direction, pivotable doors are arranged, which are actuated by a lever mechanism when the deflecting elements are displaced.
Der erfindungsgemäß vorgesehene Hebelmechanismus ist somit am Außenumfang der Umlenkelemente angeordnet. Er stört somit nicht die Durchströmung des Nebenstromkanals und ist vor Beschädigungen geschützt. Weiterhin ergibt sich eine gute Zugangsmöglichkeit zu dem Kerntriebwerk. Der Hebelmechanismus, welcher den Antrieb für die Betätigung (Verschwenkung) der Türen bildet, ist somit bei der erfindungsgemäßen Lösung in der Verkleidung des Nebenstromkanals angeordnet. Auf diese Weise kann bei platzsparender und strömungsgünstiger Ausgestaltung eine Längsverschiebung der Umlenkelemente (Kaskadenelemente) eine Verschwenkung der Türen bewirken.The inventively provided lever mechanism is thus arranged on the outer circumference of the deflecting elements. It thus does not disturb the flow through the bypass channel and is protected from damage. Furthermore, there is a good access to the core engine. The lever mechanism, which forms the drive for the actuation (pivoting) of the doors, is thus arranged in the solution according to the invention in the lining of the bypass channel. In this way, in space-saving and streamlined design, a longitudinal displacement of the deflecting elements (cascade elements) cause a pivoting of the doors.
In günstiger Weiterbildung der Erfindung ist vorgesehen, dass eine Schwenkachse der Tür im Wesentlichen in Umfangsrichtung an dem Umlenkelement ausgebildet ist. Dazu kann dieses bevorzugterweise Lagerböcke aufweisen, an welchem die jeweiligen Türen schwenkbar gelagert sind.In a favorable embodiment of the invention it is provided that a pivot axis of the door is formed substantially in the circumferential direction of the deflecting element. For this purpose, this may preferably have bearing blocks, on which the respective doors are pivotally mounted.
Die Umlenkelemente sind bevorzugterweise an einem Ringelement befestigt, welches bevorzugterweise in Strömungsrichtung hinten angeordnet ist und den Türen zugewandt ist. Somit ist es möglich, sowohl die Lagerböcke der Türen an dem Ringelement zu lagern als auch ein Lager des Hebelmechanismus.The deflecting elements are preferably fastened to a ring element, which is preferably arranged downstream in the flow direction and faces the doors. Thus, it is possible to support both the bearing blocks of the doors on the ring member as well as a bearing of the lever mechanism.
In besonders günstiger Ausgestaltung der Erfindung ist vorgesehen, dass der Hebelmechanismus einen ersten und einen zweiten Hebel umfasst. Der erste Hebel ist gehäusefest drehbar gelagert, d. h., seine Schwenkachse, welche im Wesentlichen radial zur Triebwerksachse angeordnet ist, ist bei Verschiebung der Umlenkelemente ortsfest am Gehäuse vorgesehen. Ein Ende des ersten Hebels ist somit am Gehäuse gelagert, während das zweite Ende schwenkbar mit dem zweiten Hebel verbunden ist. Das gegenüberliegende Ende des zweiten Hebels ist um eine im Wesentlichen radial angeordnete Schwenkachse verschwenkbar, welche entweder an dem Ringelement oder an dem Umlenkelement ausgebildet ist. Im Bereich des Lagers des zweiten Hebels ist dieser verlängert ausgebildet und mit einem Zwischenhebel verbunden, welcher wiederum mit einem dritten Hebel in Verbindung steht. Dieser ist schwenkbar an der Tür gelagert. Eine Axialverschiebung des Umlenkelements bzw. des Ringelements in Axialrichtung des Triebwerks führt somit zwangsläufig zu einer Relativbewegung des ersten und des zweiten Hebels. Hierdurch wird auch der dritte Hebel verschwenkt und betätigt automatisch die Türen, indem er diese verschwenkt.In a particularly favorable embodiment of the invention it is provided that the lever mechanism comprises a first and a second lever. The first lever is rotatably mounted fixed to the housing, ie, its pivot axis, which is arranged substantially radially to the engine axis, is fixedly provided on displacement of the deflection elements on the housing. One end of the first lever is thus mounted on the housing, while the second end is pivotally connected to the second lever. The opposite end of the second lever is pivotable about a substantially radially arranged pivot axis, which is formed either on the ring member or on the deflecting element. In the region of the bearing of the second lever this is formed extended and connected to an intermediate lever, which in turn communicates with a third lever. This is pivotally mounted on the door. An axial displacement of the deflecting element or the ring element in the axial direction of the engine thus leads inevitably to a relative movement of the first and the second lever. As a result, the third lever is pivoted and automatically actuates the doors by swiveling them.
