Description

Unterbrecherklappe Die vorliegende Erfindung betrifft die weitere Ausbildung der Unterbrechersteneru@ng für Flugzeuge nach Patent 707 868 und besteht im wesentlichen darin, daß die Unterbrecherklappen an ihrem Fuße mit einem schlitzförmigen oder siebartigen Durchlaß versehen sind, der beim Aufschlagen oder Ausschieben der Klappe in Erscheinung tritt und dann in der Strömung nahe der Flügeloberfläche eine Düsenwirkung erzeugt, die zur schnellen Entwicklung des endlichen Strömungszustandes hinter der Klappe beiträgt.Interrupter flap The present invention relates to the further development of the interrupter control for aircraft according to patent 707 868 and consists essentially in the fact that the interrupter flaps are provided at their foot with a slot-shaped or sieve-like passage which appears when the flap is opened or pushed out then a nozzle effect is generated in the flow near the wing surface, which contributes to the rapid development of the finite flow state behind the flap.

In der Zeichnung ist der Erfindungsgegenstand in zwei Ausführungsbeispielen schematisch im Schnitt dargestellt.In the drawing, the subject matter of the invention is shown in two exemplary embodiments shown schematically in section.

Abb. i zeigt die Unterbrecherklappe i, die im eingezogenen Zustande in einer spaltförmig ausgebildeten, vorzugsweise mit einer Ausblaseeinrichtung versehenen Öffnung 2 innerhalb .der Flügelkontur gehalten wird und beim Heraustreten aus dieser zwischen Flügeloberfläche und Klappe einen Schlitz 3 entstehen läßt, dessen Weite veränderlich ist.Fig. I shows the interrupter flap i, which is in the retracted state in a gap-shaped design, preferably provided with a blow-out device Opening 2 is held within .der wing contour and when stepping out of this a slot 3 can arise between the wing surface and the flap, the width of which is changeable.

Abb. a zeigt die nach Art einer Windstütze schwenkbare Unterbrecherklappe q., die sich im eingeschlagenen Zustande der jeweiligen Flügeloberfläche einpaßt und beim Aufschlagen etwa in der Ebene der Flügelkontur einen Durchlaß 5 aufweist, dessen Weite gegebenenfalls regelbar sein kann. Darüber hinaus wird die Klappenanordnung vornehmlich mit einer Ausblaseeinrichtung 6 verbunden, die einmal dazu dient, die Düsenwirkung der aufgeschlagenen Klappe zu erhöhen und zum anderen bei Veriv endung eines erwärmten Ausblasemittels auch im eingezogenen Zustande der Klappe eine etwaige Vereisung der Klappenanordnung verhindert.Fig. A shows the interrupter flap which can be pivoted like a wind support q., which fits into the respective wing surface when it is turned and has a passage 5 when striking approximately in the plane of the wing contour, whose width can optionally be adjustable. In addition, the flap assembly primarily connected to a blow-out device 6, which serves once to the To increase the nozzle effect of the open flap and, on the other hand, when used a heated blow-out means even when the flap is in the retracted state Prevents the flap arrangement from icing up.

PATENTANSPRÜCHE: i. Tragflügelanordnung nach Patent 707 868, dadurch gekennzeichnet, dalä die vorzugsweise nach Art einer Windstütze angeordneten Unterbrecherklappen an ihrem Fuße mit einem schlitzförmigen oder siebartigen Durchlaß versehen sind, der beim Ausschlagen oder Ausschieben der Klappe in Erscheinung tritt und gegebenenfalls in seiner Weite regelbar ist. z. Tragflügelanordnung nach Anspruch i, dadurch gekennzeichnet, daß die Unterbrecherklappe im eingeschlagenen Zustande die Öffnungen) einer hier in die Flüigeloberfläche mündenden Ausblaseeinrichtung ganz oder zum Teil freigibt.PATENT CLAIMS: i. Wing arrangement according to patent 707 868, characterized in that the interrupter flaps, which are preferably arranged in the manner of a wind support, are provided at their foot with a slot-shaped or sieve-like passage, which appears when the flap is opened or pushed out and its width can be regulated if necessary. z. Airfoil arrangement according to Claim i, characterized in that the interrupter flap in the folded-in state completely or partially releases the openings of a blow-out device opening here into the wing surface.
