Description
Flugzeug mit in Hubstellung schwenkbarer Luftschraube Es sind Flugzeuge bekannt, bei denen die Luftschraube, die im Horizontalflug den Vortrieb erzeugt, bei Start und Landung um 90° geschwenkt werden kann, um als Hubschraube zu wirken. Diese Flugzeuge haben, soweit sie nur eine Luftschraube besitzen, den Nachteil, daß im Betriebszustand als Hubschrauber der Rumpf des Flugzeuges entgegengesetzt der Luftschraube in Drehung versetzt wird.Airplane with propeller that can be swiveled in lift position There are airplanes known, in which the propeller, which generates the propulsion in level flight, can be swiveled by 90 ° during take-off and landing in order to act as a jack screw. As far as they only have one propeller, these aircraft have the disadvantage that in the operating state as a helicopter, the fuselage of the aircraft is opposite the propeller is set in rotation.
Die Erfindung beseitigt diesen Nachteil dadurch, daß bei Stellung der Luftschraube als Hubschraube die Tragflügel des Flugzeuges vom Triebwerk entgegen dem Drehsinn der Luftschraube in Drehung versetzt werden.The invention eliminates this disadvantage in that at position the propeller acts as a jack screw against the wing of the aircraft from the engine the direction of rotation of the propeller.
Weitere Einzelheiten der Erfindung gehen aus der nachfolgenden Beschreibung hervor, in der ein Ausführungsbeispiel an Hand der Zeichnungen erläutert ist. Diese zeigen das Flugzeug nach der Erfindung in Fig. 1 als Hubschrauber, Fig. 2 als Starrflügelflugzeug, Fig. 3 mit tiefliegendem Motor als Hubschrauber, Fig. 4 mit tiefliegendem Motor als Starrflügelflugzeug ; Fig. 5, 6 und 7 zeigen ein verwandelbares Tragflügelprofil.Further details of the invention can be found in the following description in which an embodiment is explained with reference to the drawings. These show the aircraft according to the invention in Fig. 1 as a helicopter, Fig. 2 as a fixed-wing aircraft, Fig. 3 with a low-lying engine as a helicopter, Fig. 4 with a low-lying engine as a fixed wing aircraft; Figures 5, 6 and 7 show a convertible airfoil.
Nach den Fig. 1 und 2 ist der Motor 2 mit der Luftschraube 1 in einer Gabel 3 schwenkbar gelagert, die ihrerseits um eine senkrechte Achse drehbar ist. Die Tragflügel 4, 5 sind an der Gabel 3 befestigt. Bei Betrieb als Hubschrauber dreht sich die Luftschraube in der einen und die Gabel 3 mit dem Motor 2 und den Tragflügeln 4, 5 in der anderen Richtung.According to FIGS. 1 and 2, the motor 2 is in one with the propeller 1 Fork 3 pivotably mounted, which in turn is rotatable about a vertical axis. The wings 4, 5 are attached to the fork 3. When operated as a helicopter turns the propeller in one and the fork 3 with the motor 2 and the Wings 4, 5 in the other direction.
Jeder Tragflügel ist unterteilt in einen äußeren Teil 4 und einen inneren Teil 5 im Bereich der Luftschraube 1. Die beiden inneren Teile 5 der Tragflügel werden mit der Luftschraube 1 und dem Motor 2 verschwenkt. Außerdem können sie so gegeneinander eingestellt werden, daß der Luftschraubenstrahl die Gegendrehung der Tragflügel unterstützt.Each wing is divided into an outer part 4 and an inner part 5 in the area of the propeller 1. The two inner parts 5 of the wings are pivoted with the propeller 1 and the motor 2. In addition, they can be set against each other so that the propeller jet supports the counter-rotation of the wings.
Die äußeren Teile 4 der Tragflügel machen die Verschwenkung der Luftschraube nicht mit. Sie werden lediglich gegeneinander verstellt, so daß sie als Hubschraubenflügel wirken.The outer parts 4 of the wings make the pivoting of the propeller not with. They are only adjusted against each other so that they act as lifting screw wings works.
Nach der Fig. 3 ist der Motor aus Stabilitätsgründen unterhalb des Flugzeugrumpfes angeordnet. Beim Verschwenken der Luftschraube 1 in die Stellung als Hubschraube legt sich die Luftschraubenwelle 7 in eine längs geschlitzte Hohlwelle 6 ein, mit der die Tragflügel 4, 5 drehfest verbunden sind. Der Motor 2 kann an der Drehung der Tragflügel teilnehmen oder rumpffest angeordnet und über ein Differentialgetriebe mit der Luftschraube und den Tragflügeln verbunden sein.According to Fig. 3, the engine is below the for stability reasons Arranged aircraft fuselage. When pivoting the propeller 1 into the position As a lifting screw, the propeller shaft 7 lies in a longitudinally slotted hollow shaft 6, with which the wings 4, 5 are rotatably connected. The motor 2 can Participate in the rotation of the wings or fixed to the fuselage and via a differential gear be connected to the propeller and the wings.
Bei Rotation der Tragflügel ist einer von ihnen einer Strömungsumkehrung ausgesetzt. Es sind Einrichtungen bekannt, um die stumpfe Vorderkante eines Tragflügels in eine scharfe Hinterkante und umgekehrt zu verwandeln, indem die Tragflügelwände 9, 10 um eine Achse 11 längs der Spannweite schwenkbar sind. Erfindungsgemäß ist im Innern des einen Tragflügels längs der beiden Tragflügelkanten je ein Schlauch 12 angeordnet, von denen jeweils einer aufgeblasen ist und die stumpfe Vorderkante bildet. Gummibänder 13, 14 ziehen den jeweils nicht aufgeblasenen Schlauch in das Innere des Tragflügels.When the wings rotate, one of them is a flow reversal exposed. There are devices known to the blunt leading edge of a wing transform into a sharp trailing edge and vice versa by removing the wing walls 9, 10 are pivotable about an axis 11 along the span. Is according to the invention in the interior of one wing along the two wing edges each have a hose 12 arranged, one of which is inflated and the blunt leading edge forms. Rubber bands 13, 14 pull the uninflated tube into the Interior of the wing.
