Abstract

An air vehicle, lighter than air with a flexible outer hull and several separated inner gas cells has the separated inner gas cells fastened above and below the flexible outer hull. The stability of the outer hull against dynamic and static bending moments is generated by an appropriate inner excess pressure inside the outer hull. The stagnation pressure is carried by an appropriate inner excess pressure inside the outer hull. Static bending moments are largely avoided between sections of the outer hull that belong to different gas cells but through a correspondingly subdivided suspension of all loads below the different gas cells. For the accommodation of the dynamic bending moments during flight, folding of the outer hull is allowed between sections that belong to the individual gas cells.

Description

Es ist bekannt, Pralluftschiffe mit einem oder mehreren Ballonets auszustatten, um den Innendruck unabhängig von der Ausdehnung des Traggases regeln zu können. Der Größe dieser Ballonets ist allerdings begrenzt, da Schwappeffekte der Ballonetluft zunehmend stärker werden und einen kontrollierten Flug erschweren. Das beschränkt auch die Einsatzhöhe.It is known to equip impact airships with one or more ballonets in order to control the internal pressure to be able to regulate regardless of the expansion of the carrier gas. The size of these ballonets is however limited, as sloshing effects of the balloon air become increasingly stronger and one difficult controlled flight. This also limits the bet size.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, diese Schwierigkeit zu umgehen und das Pralluftschiff für wesentlich größere Einsatzhöhen nutzen zu können. Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.The invention specified in claim 1 is based on the problem, this difficulty to bypass and use the impact airship for much greater heights. This Problem is solved by the features listed in claim 1.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß
The advantages achieved by the invention are in particular that

  • - durch die Anwendung von einzelnen Gaszellen, die oben und unten an der äußeren Hülle befestigt sind und durch die Nutzung des Zwischenraumes zwischen den Gaszellen und der äußeren Hülle als Raum für die Ballonetluft das Schwappen der Gaszellen selbst bis zu sehr geringen Füllungsgraden weitgehend unterbunden bleibt und damit größere Gipfelhöhen erreichbar sind.- through the use of individual gas cells, which are attached to the top and bottom of the outer shell and by using the space between the gas cells and the outer shell as a space for the Ballonet air, the sloshing of the gas cells themselves to a very low level Filling levels are largely prevented and thus higher summit heights can be reached.
  • - die Forderungen an die Gasdichtigkeit der Außenhülle wesentlich geringer sind und eine Havarie der Außenhülle wesentlich geringere Folgen hat.- The requirements for the gas tightness of the outer shell are much lower and an accident the outer shell has significantly fewer consequences.
  • - ein Füllen des ganzen Luftschiffes ähnlich wie bei Starrluftschiffen durch gleichmäßiges Befüllen der Gaszellen bei fester Außenform möglich wird und die komplizierten Techniken für herkömmliche Pralluftschiffe entfallen können.- Filling the entire airship similar to rigid airships by even filling the gas cells with a solid outer shape is possible and the complicated techniques for conventional impact airships can be dispensed with.
  • - die Gaszellen durch die Anordnung im Inneren wesentlich besser geschützt vor mechanischen Verletzungen geschützt sind.- The gas cells are much better protected from mechanical by the arrangement inside Injuries are protected.
  • - die Gaszellen besser vor Temperaturveränderungen geschützt sind.- The gas cells are better protected against temperature changes.

Eine mögliche Ausgestaltung der Erfindung ist im Patentanspruch 2 angegeben. Die Weiterbildung nach Patentanspruch 2 ermöglicht den Bau von zusammenfaltbaren Luftschiffen mit beliebig verteilten Lasten und Stabilisierung durch Leitwerke, die größere Gipfelhöhen als herkömmliche Pralluftschiffe erreichen können und von allen weiteren Vorteilen nach Patentanspruch 1 profitieren. A possible embodiment of the invention is specified in claim 2. Continuing education according to claim 2 allows the construction of collapsible airships with any distributed loads and stabilization through tail units that have greater summit heights than conventional ones Can reach impact airships and all other advantages according to claim 1 benefit.  

Eine weitere mögliche Ausgestaltung der Erfindung ist im Patentanspruch 3 gegeben. Ein Luftschiff nach Patentanspruch 3 kommt, weil die statischen und dynamischen Momente nicht mehr von der Außenhülle aufgenommen werden müssen, mit wesentlich geringerem Innendruck und damit einer leichteren äußeren Hülle aus als eines nach Patentanspruch 2.Another possible embodiment of the invention is given in claim 3. On Airship according to claim 3 comes because the static and dynamic moments are not more of the outer shell have to be absorbed, with much lower internal pressure and thus a lighter outer shell than one according to claim 2.

Eine vorteilhafte Ausgestaltung der in Patentanspruch 3 erwähnten automatischen Regelung ist in Patentanspruch 4 gegeben. Die Weiterbildung nach Patentanspruch 4 ermöglicht gesteuerten stabilen Flug eines Luftschiffes nach Patentanspruch 3 mit stark verkleinertem oder sogar ohne Leitwerk und minimalem Leistungsbedarf für die Regelung.An advantageous embodiment of the automatic control mentioned in claim 3 is in Claim 4 given. The training according to claim 4 enables controlled stable flight of an airship according to claim 3 with greatly reduced or even without Tail and minimum power requirement for the control.

Eine vorteilhafte Ausgestaltung der Befestigung der Gaszellen oben und unten an der flexiblen äußeren Hülle aus Patentanspruch 1 ist in Patentanspruch 5 gegeben. Eine solche Befestigung ermöglicht den Austausch von Gaszellen sowie gute Lasteinleitung in die Gaszellen.An advantageous embodiment of the attachment of the gas cells at the top and bottom of the flexible outer shell from claim 1 is given in claim 5. Such an attachment enables the exchange of gas cells and good load transfer into the gas cells.
