Description

Flugzeug mit um vertikale Achsen schwenkbaren Tragflächen Es ist für Flugzeuge mit um vertikale Achsen schwenkbaren Tragflächen bekannt, die Schwenkachsen zugleich mit der Schwenkung der Tragflächen in Flugzeuglängsrichtung zu verlagern. Da an den Schwenkachsen große Kräfte angreifen, erfordert die genügend steife Lagerung der beweglichen Schwenkachsen jedoch einen erheblichen Aufwand. Nach der Erfindung werden diese Schwierigkeiten dadurch umgangen, daß an der Wurzel jeder Tragfläche zwei in Flugzeuglängsrichtung hintereinanderliegende und zugleich zur Verriegelung der Tragfläche dienende Schwenklager vorgesehen sind, um die jede Tragfläche wahlweise nach einwärts bis an Verriegelungslager schwenkbar ist.Airplane with wings pivoting about vertical axes It is for Aircraft with wings pivotable about vertical axes are known, the pivot axes to shift at the same time with the pivoting of the wings in the aircraft longitudinal direction. Since large forces act on the swivel axes, they require a sufficiently rigid mounting the movable pivot axes, however, a considerable effort. According to the invention these difficulties are circumvented by having at the root of each wing two in the aircraft longitudinal direction one behind the other and at the same time for locking wing pivot bearings are provided around which each wing is optional can be pivoted inwards to the locking bearing.

An Hand der schematischen Figur, welche eine Draufsicht auf den mittleren Rumpfteil eines Flugzeuges darstellt, soll die Erfindung nachfolgend an einem Ausführungsbeispiel erläutert werden.On the basis of the schematic figure, which is a top view of the middle Representing the fuselage part of an aircraft, the invention is intended to be based on an exemplary embodiment explained.

Die Tragflächen 1, 2 weisen an der Wurzel in Flugzeuglängsrichtung hintereinanderliegende und zugleich zur Verriegelung der Tragfläche dienende Schwenklager 3 bis 6 auf. Die Tragflächen können in drei verschiedenen Stellungen verriegelt werden, wofür am Rumpfteil zusätzlich zwei Verriegelungslager 7, 8 vorgesehen sind.The wings 1, 2 have pivot bearings 3 to 6 which are located one behind the other in the longitudinal direction of the aircraft and also serve to lock the wing. The wings can be locked in three different positions, for which two locking bearings 7, 8 are also provided on the fuselage part.

Betrachtet sei zunächst die strichpunktiert dargestellte Tragflächeneinstellung mit negativer Pfeilung. In dieser Lage sind die an den Tragflächenwurzeln angebrachten Lager in den Punkten 9 sowie 3 und 4 verriegelt. Zur Verstellung in die ausgezogen dargestellte Lage werden die Tragflächen 1, 2 im Punkt 9 entriegelt und durch den hydraulischen Zylinder 8 so weit um die Punkte 3 und 4 nach außen geschwenkt, bis die Lager an den Tragflächen in den Punkten 5 und 6 am Rumpf verriegelt werden könneu. Der übergang in die gestrichelt dargestellte Lage erfolgt nach Lösen der Riegel bei 3 und. 4 durch Schwenkung um die Punkte 5 und 6 auf den Riegelpunkt 7.First, consider the wing setting shown in dash-dotted lines with a negative arrow. In this position the bearings attached to the wing roots are locked in points 9 as well as 3 and 4. To adjust to the position shown in full lines, the wings 1, 2 are unlocked at point 9 and pivoted outward by the hydraulic cylinder 8 around points 3 and 4 until the bearings on the wings are locked at points 5 and 6 on the fuselage can be new. The transition to the position shown in dashed lines takes place after loosening the latches at 3 and. 4 by pivoting around points 5 and 6 onto locking point 7.
