Abstract

The hot-air balloon is deflated after landing not by means of a top valve, as is normally the case, but rather by being tipped over using a top cord attached to the suspended seat. The hot-air entrance port is used in deflating and is enlarged considerably. During the filling and heating-up process the envelope is held down by ground attachments to the top cord and lower border of the envelope.

Description

HEISSLUFTBALLONHOT AIR BALLOON
Bei den bekannten Heissluftballonen bestehen beim Landen besondere Probleme, wenn mindestens eine der folgenden Bedingungen zutreffen:The known hot air balloons have special problems when landing if at least one of the following conditions applies:
- Einmannbesetzung,- one-man cast,
- Luftzug oder gar Wind,- draft or even wind,
- keine Hilfe von Drittpersonen,- no help from third parties,
- Hindernisse wie Bäume oder Gebäude im Landeterrain.- Obstacles such as trees or buildings in the landing terrain.
Der Grund der Probleme beruht darauf, dass das Landegewicht durch den noch vorhan¬ denen Auftrieb zu klein ist. Dabei verliert er jeglichen Grip auf dem Boden und kann ein Wegdriften und eine daraus resultierende Gefährdung oder eine Beschädigung des Ballons oft nicht verhindern. Durch den langsamen und unvollständigen Entlehrungsvor- gang mit dem Topventil, ist die Gefahr von Schleif flandungen sehr gross!The reason for the problems is based on the fact that the landing weight is too small due to the still existing lift. It loses all grip on the ground and often cannot prevent it from drifting away and the resulting danger or damage to the balloon. Due to the slow and incomplete tapping process with the top valve, the risk of grinding landings is very high!
••
Es ist deshalb Aufgabe der Erfindung, einen Ballon zu schaffen, der beim Landen sofort und vollständig entleert werden kann, was eine sichere Landung in jedem Gelände und auch bei seitlichen Winden gewährleistet, selbst wenn ein einziges Besatzungsmitglied die Landung ganz allein vornehmen muss.It is therefore an object of the invention to provide a balloon which can be emptied immediately and completely when landing, which ensures a safe landing in any terrain and even in side winds, even if a single crew member has to make the landing all by himself.
Diese Aufgabe wird gelöst durch einen Ballon gemäss den Patentansprüchen.This object is achieved by a balloon according to the patent claims.
Die Erfindung wird anhand eines Heissluftballons erläutert. Sie eignet sich aber grundsätzlich für jedes Traggas, das am Ende eines Fluges nicht geborgen werden muss, sondern (mindestens im Notfall) aufgegeben werden kann.The invention is explained using a hot air balloon. In principle, however, it is suitable for any lifting gas that does not have to be recovered at the end of a flight, but can be abandoned (at least in an emergency).
Nachstehend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels erläu¬ tert:The invention is explained below on the basis of a preferred exemplary embodiment:
Figuren 1 + la zeigen in der Seitenansicht einen Heissluftballon mit einer Hülle H, einem Sitzgestell, einem Brenner als Heisslufterzeuger sowie mit einer Topleine T. Brenner und Sitz sind durch eine Tragkonstruktion an der Hülle befestigt. Die bisher übliche Topöffnung wird durch seitlich angeordnete Nentile ersetzt. Diese ermöglichen u. a. einen sichereren Sinkflug mit einer geringfügigen Fahrt, statt einer Drehung im Falle der Benutzung eines einzigen Seitenventils oder eines drallgleichen Paares. Diese Landungsart eignet sich besonders bei leichten Winden. Bei absoluter Windstille und genau vertikaler Landerichtung genügt dagegen das Ab¬ schalten des Brenners oder dessen Leistungreduktion.Figures 1 + la show in side view a hot air balloon with an envelope H, a seat frame, a burner as a hot air generator and with a top line T. Burner and seat are attached to the envelope by a support structure. The previously usual top opening is replaced by side valves. These enable, among other things, a safer descent with a slight ride, instead of turning when using a single side valve or a pair of swirls. This type of landing is particularly suitable for light winds. On the other hand, when the wind is completely calm and the landing direction is exactly vertical, it is sufficient to switch off the burner or reduce its output.
Figuren 2 + 2a zeigen die Ballonhülle von Unten.Figures 2 + 2a show the balloon envelope from below.
Erfindungsgemäss sind am unteren Teil der Hülle Laschen L angeordnet. Wenn vier solche Laschen vorhanden sind, können die dazwischenliegenden Segmente S der Hülle beim Umkippen derselben den gewünschten Ballonquerschnitt freigeben, was eine mo¬ mentane Entleerung ermöglicht, damit entfällt der Auftrieb sofort. Das bedeutet, dass der Pilot beim Landen seinen Sitz risikolos (durch an sich bekannte Mittel) ausklinken kann. Am Sitzgestell oder Korb sind die Topleine T und vorzugsweise auch der Brenner befestigt. Die bevorzugte Befestigung der Topleine am Sitzgestell oder Korb, gewährlei¬ stet in jedem Fall ein rechtzeitiges Kippen und Entleeren der Ballonhülle. Im Flugbetrieb wirkt das Traggas im wesentlichen auf die obere Hälfte der Hülle und die Laschen L sind nur geringer Beanspruchung ausgesetzt. In der Regel lässt man sie aber seitlich abstehen, was dem Ballon eine besondere optische Charakteristik gibt. Nach einem Kippen des Ballons dagegen wirkt das Traggas auf den Innenraum der La¬ schen. Dadurch werden die Laschen sofort aufgebläht, so dass auch die Segmente S ebenfalls vom Traggas beaufschlagt - derart auseinander gehen, dass der gewünschte querschnitt der Hülle freigegeben wird. Dabei diehnt der Auftrieb nur noch der Oeffnung der Laschen und Segmente und damit nicht mehr dem Anheben der Hülle. Diese fällt unter ihrem Eigengewicht völlig entleert auf den Boden und kann an Ort und Stelle geborgen werden.According to the invention, tabs L are arranged on the lower part of the casing. If there are four such tabs, the segments S of the sheath located between them can release the desired balloon cross-section when it tilts over, which enables a momentary deflation, so that the buoyancy is immediately eliminated. This means that the pilot can safely release his seat (by means known per se) when landing. The topline T and preferably also the burner are attached to the seat frame or basket. The preferred attachment of the topline to the seat frame or basket ensures in any case timely tilting and emptying of the balloon envelope. In flight operations, the carrier gas essentially acts on the upper half of the shell and the tabs L are exposed to only slight stress. As a rule, however, they are left to protrude laterally, which gives the balloon a special optical characteristic. After tilting the balloon, however, the lifting gas acts on the interior of the tabs. As a result, the tabs are inflated immediately, so that the segments S are also subjected to the carrier gas - diverge in such a way that the desired cross section of the casing is released. The buoyancy only relies on the opening of the tabs and segments and therefore no longer on lifting the casing. This falls completely empty on the floor under its own weight and can be recovered on the spot.
Die an sich gefährliche Landung bei kräftigen Winden wird relativ sicher, weil der Winddruck in Kombination mit dem Sog an der Lee-Seite die Entleerung der Ballonhül¬ le noch beschleunigt. (13 bis 15 Sekunden!) The dangerous landing in strong winds becomes relatively safe because the wind pressure in combination with the suction on the leeward side accelerates the emptying of the balloon envelope. (13 to 15 seconds!)
