Abstract
Description
Die Erfindung betrifft eine einfache Flugzeugtragfläche, bei der das Profil im Flug an unterschiedliche Bedingungen angepasst werden kann. Es werden der Auftrieb, der Widerstand und das Steuern beeinflusst.The The invention relates to a simple aircraft wing, in the profile adapted in flight to different conditions can be. It will be the buoyancy, the resistance and the steering affected.

die Erfindung wird die gleiche Aufgabenstellung wie in
Der erfindungsgemäße Flugzeugtragflügel besteht aus einer starren Ober- und Unterhaut im vorderen Bereich von der Anströmkante über den Holm bis zur Rückwand und einer flexiblen Ober- und Unterhaut, die nahtlos an die starre Haut anschließt und an der Flügelhinterkante offen ist. Im Innern des flexiblen Flügelteils befindet sich, an der Rückwand lagernd befestigt, eine Drehvorrichtung, an der zwei sich kreuzende Zugseile die Flügelhinterkante nach oben oder unten bewegen. Durch Lösen der Lager an der Rückwand oder durch Lösen eines Zugseiles ist die Mechanik für Kontroll- oder Wartungsarbeiten zugänglich. Es besteht auch die Möglichkeit für den Fall einer großen Durchbiegung des Flügels bei Belastungen, die Flügelhinterkante in mehrere Abschnitte zu trennen, so dass die Betätigung entsprechender Steuerknüppel leicht gängig ist. Eine gleichzeitige Veränderung der Flügelhinterkante nach oben und unten ist nicht beabsichtigt, da im Flug die Widerstandserhöhung nicht so groß ist wie bei herkömmlichen Bremsklappen und die Zugseile durch aufwendige Schub- und Druckstangen ersetzt werden müssten.Of the inventive aircraft wing consists from a rigid upper and lower skin in the front area of the Leading edge over the spar to the rear wall and a flexible upper and lower skin that fits seamlessly to the rigid one Skin connects and open at the wing trailing edge is. Inside the flexible wing part is, mounted on the rear wall in stock, a turning device, at the two intersecting pull ropes the wing trailing edge move up or down. By loosening the bearings at the Rear wall or by loosening a pull rope is the Mechanics accessible for inspection or maintenance. There is also the possibility in the case of one large deflection of the wing under loads, separating the wing trailing edge into several sections, allowing the operation of appropriate control sticks easy is common. A simultaneous change the wing trailing edge up and down is not intended because in flight the increase in resistance is not so great as with conventional airbrakes and the pull ropes through consuming push rods and push rods would have to be replaced.
Anhand von Zeichnungen wird ein Ausführungsbeispiel der Erfindung näher erläutert.Based of drawings will become an embodiment of the invention explained in more detail.
