Description

Die Flügel rotierender Flügelsysteme werden vielfach gelenkig mit ihrer Nabe verbunden, so daß sie sich, unter dem Einfluß der Luftströmung aus ihrer Umlauffläche herausbewegen tonnen. Um den beweglichen Flügeln an der Anlenkungsstelle eine breite Basis geben zu können, hat man bekanntlich die Gelenke an die Enden kurzer, mit der Nabe starr verbundener Armstücke gelegt. Diese haben kreisrunden oder ovalen Querschnitt. Das eigentliche Flügelprofil ist nur bei dem beweglichen Flügelteil vorhanden. Diese an sich bekannte Anordnung kann man nicht anwenden, wenn es sich, um ein Flügelsystem mit Reaktionsantrieb handelt, denn in diesem Falle müßten die mit der Nabe starr verbundenen Armstücke für den Durchtritt des Treibmittels hinreichend bemessen, d.h. wesentlich stärker als sonst sein und wurden daher einen erheblichen Luftwiderstand finden, und andererseits würden die Gelenke an den Wurzeln der beweglichen Flügelteile in den bisher bekannten Formen zur Überleitung des Treibmittels aus den starren Armstücken in die beweglichen Flügelteile ungeeignet sein.The wings of rotating wing systems are often articulated to their hub, so that they move out of their orbit under the influence of the air flow metric tons. A wide base around the movable wings at the point of articulation It is well known that the joints are shorter at the ends, with the hub rigidly connected arm pieces. These have a circular or oval cross-section. The actual wing profile is only with that movable wing part available. This arrangement, which is known per se, cannot be used, if it is a wing system with reaction drive, because in this one Case would have to be rigidly connected to the hub arm pieces for the passage of the Sufficiently dimensioned propellant, i.e. be and have been much stronger than usual therefore find considerable air resistance, and on the other hand the joints would at the roots of the movable wing parts in the previously known forms for transition the propellant from the rigid arm pieces in the movable wing parts is unsuitable be.

Die vorliegende Erfindung schafft hierin einen technischen Fortschritt, indem sie empfiehlt, den kurzen Armstücken, welche starr an der Nabe befestigt sind, Flügelprofil zu geben und die Gelenke mit gasdichten Hüllen zu umgeben, welche die Flügelprofile der starren Armstücke in die Profile der gelenkig angeschlossenen Flügel überführen. Die starr an der Nabe befestigten Armstücke mit Flügelprofil nehmen an der Hubarbeit des ganzen umlaufenden Systems teil und finden einen wesentlich geringeren Luftwiderstand als Arme mit kreisrundem oder elliptischem Querschnitt. Die gasdichte Umhüllung der Gelenke ermöglicht das Überleiten des Treibmittels aus den starren Armstücken in die gelenkig angeschlossenen Flügel und vermeidet 'eine Unterbrechung des Flügelprofils an den Gelenken.The present invention provides a technical advance herein by recommends using the short arm pieces, which are rigidly attached to the hub, wing profile to give and to surround the joints with gas-tight covers, which the wing profiles of the rigid arm pieces in the Transfer the profiles of the hinged wings. The rigidly attached to the hub Arm pieces with wing profile take part in the lifting work of the whole circulating system part and find a much lower air resistance than arms with a circular or elliptical cross-section. The gastight covering of the joints enables the propellant to be passed over from the rigid ones Arm pieces in the hinged wing and avoids an interruption of the wing profile at the joints.

In der Zeichnung sind mehrere Ausführungsbeispiele dargestellt.Several exemplary embodiments are shown in the drawing.

Abb. ι zeigt den mittleren Teil eines erfindungsgemäßen Flügelsystems. An dem Hals ι des nicht gezeichneten Flugzeuges ist mittels eines Drehkranzes die Nabe 2 des Flügelsystems drehbar befestigt. In der Nabe rotiert der mittels der Welle 3 motorisch angetriebene Ventilator 4. Die Nabe hat entsprechend der Zahl der umlaufenden Tragflügel eine Anzahl kurzer Flügelenden oder Arme 5, welche in tangentialen Schnitten Flügelprofil haben. An diesen kurzen Armen sind mittels der Gelenke 6 die hohlen Flügel 7 angeschlossen. Das Entweichen des Treibmittels wird verhindert durch gasdichte Hüllen 8, welche aus einem nachgiebigen Stoff bestehen.Fig. Ι shows the middle part of an inventive Wing system. Is on the neck ι of the aircraft not shown the hub 2 of the wing system is rotatably attached by means of a slewing ring. In the hub the motor-driven fan 4 rotates by means of the shaft 3. The hub has accordingly the number of rotating wings a number of short wing tips or Arms 5, which have wing profile in tangential sections. On these short arms the hollow wings 7 are connected by means of the joints 6. The escape of the propellant is prevented by gas-tight envelopes 8, which are made of a flexible material.

Abb. 2 zeigt ein Flügelsystem, welches sich von dem in Abb. 1 dargestellten nur dadurch unterscheidet, daß die Gelenke 6 in der gemeinsamen Mittelebene der Flügel angebracht sind.Fig. 2 shows a wing system, which differs from the one shown in Fig. 1 only in this way distinguishes that the joints 6 are mounted in the common center plane of the wings are.
