Description

Gegenstand der Erfindung ist ein Axialleitschaufelsystem zur Erzeugung einer rotierenden _ Strömung, insbesondere zur Förderhöhenregelung bei Flugmotoren.The invention relates to an axial guide vane system for generation a rotating flow, especially for the delivery height control of aircraft engines.

Erfindungsgemäß bestehen die Leitschaufeln aus biegsamen Stahlblechen, die in offenem Zustand des Leitsehaufelsystems eine ebene Fläche in Srömungsrchtung iznd im geschlossenen Zustand den Teil einer Kegelmantelfläche bilden. Die Verstellung der Leitschaufeln wird dadurch bewirkt, daß die Einspännstellen der biegsamen Schaufeln verdreht werden, wobei die anderen Enden der Bleche mittels Stege in entsprechenden Kulissen geführt werden und alle unteren Stegenden drehbar in Pfannen gelagert sind. Der Nabenkörper ist hierbei starr mit einem die Einspannstelle der Blechschaufeln aufweisenden Rippenstern verbunden und besitzt Kreisbogenkulissen, in welchen sich die Stege bei der Verstellung bewegen. !, Ein Ausführungsbeispiel ist in der Zeichnung schematisch dargestellt.According to the invention, the guide vanes are made of flexible steel sheets, in the open state of the guide vane system a flat surface in the direction of flow iznd form part of a conical surface in the closed state. The adjustment the guide vanes is caused by the clamping points of the flexible vanes are twisted, the other ends of the sheets by means of webs in corresponding Scenes are performed and all lower web ends are rotatably mounted in pans. The hub body is rigid with one of the clamping points of the sheet metal blades having rib star connected and has circular arc scenes in which move the bars when adjusting. !, An exemplary embodiment is shown in the drawing shown schematically.

Die Leitschaufeln i bestehen aus biegsamen Blechschaufeln und stehen mit einem Rippenstern 2 in Verbindung. An der dem Rippenstern abgewandten Seite sind Stege 3 vorgesehen, die durch den Nabenkörper q, hindurchgehen und in den Pfannen 5 gelagert sind. Die Stege tragen am anderen Ende Rollen 6, welche sich in Kreisbogenkulissen 7 der Kulissentrommel ä verschieben können. Eine Drehbewegung wird beispielsweise über das Schneckenradsegment 9 und die Schnecke io von außen eingeleitet.The guide vanes i consist of flexible sheet metal vanes and stand with a rib star 2 in connection. On the side facing away from the rib star webs 3 are provided which pass through the hub body q and in the pans 5 are stored. The webs carry rollers 6 at the other end, which are arranged in circular arc scenes 7 of the link drum ä can move. A rotary movement is for example initiated from the outside via the worm wheel segment 9 and the worm io.
