Description
Die Erfindung betrifft ein Luftfahrzeug leichter als Luft, bei dem als Traggas Heli um eingesetzt wird.The invention relates to an aircraft lighter than air, with the helicopter as the lifting gas to be used.
Die geltenden Bauvorschriften für Luftschiffe verlangen die Verwendung eines nicht brennbaren Traggases. Üblicherweise kommt hier Helium zum Einsatz. Das Traggasvolumen wird mit diesem Gas in der höchstmöglichen Reinheit befüllt, um den maximalen Auftrieb zu erhalten und damit die maximale Nutzlast zur Ver fügung zu haben.The current building regulations for airships require the use of a non-flammable carrier gas. Usually helium is used here. That Carrying gas volume is filled with this gas in the highest possible purity, to get the maximum buoyancy and thus the maximum payload for ver to have good fortune.
Beim Bau und insbesondere während der Erprobung eines Luftschiffes ist es oft mals unumgänglich, den mit Traggas befüllten Raum zu betreten und Montage- oder Wartungsarbeiten durchzuführen.It is often during the construction and especially during the testing of an airship time it is imperative to enter the room filled with lifting gas and or perform maintenance work.
Es ist allgemein bekannt, daß zum Betreten eines mit Helium befüllten Raumes eine spezielle Schutz- und Atemausrüstung erforderlich ist. Die Ausrüstung der "Heliumtaucher" behindert die Bewegungsfreiheit. Die Aufenthaltsdauer im He liumraum ist mit dieser Ausrüstung aus arbeitsschutzrechtlichen Gründen eng li mitiert. Die "Heliumtaucher" benötigen eine entsprechende Qualifikation. Damit werden Einsätze sehr aufwendig und kostspielig.It is well known that to enter a room filled with helium special protective and breathing equipment is required. The equipment of the "Helium diver" hinders freedom of movement. The length of stay in the He liumraum is tightly connected with this equipment for health and safety reasons mitiert. The "helium divers" require an appropriate qualification. In order to operations become very complex and costly.
Im Zuge der Erprobung eines neuen Luftfahrtgerätes ist es üblich, zunächst die Belastungen am Gerät durch entsprechende Flugbetriebseinschränkungen zu limitieren. Das geschieht bei Flächenflugzeugen üblicherweise durch eine zu nächst stark reduzierte Fluggeschwindigkeit verbunden mit Wettereinschrän kungen. Bei Luftschiffen, die eine recht geringe Fluggeschwindigkeitsspanne auf weisen, liefern diese Maßnahmen nur beschränkten Erfolg. Die aerodynami schen Belastungen ergeben oftmals schon bei geringen Geschwindigkeiten La sten nahe am Maximum. Besonders kritisch sind die Böen-Lastfälle.In the course of testing a new aviation device, it is customary to first use the Loads on the device due to corresponding flight operation restrictions limit. In the case of fixed-wing aircraft, this is usually done by a next greatly reduced airspeed combined with weather restrictions kungen. In airships that have a fairly low airspeed range these measures have only limited success. The aerodynami cal loads often result in La even at low speeds most close to the maximum. The gust load cases are particularly critical.
Aufgabe der Erfindung ist, ein Luftfahrzeug leichter als Luft während des Baues ohne Schutzausrüstung im Traggasraum begehbar zu gestalten und/oder die strukturelle Grundbelastung während der Flugerprobung ohne bauliche Änderun gen deutlich zu reduzieren.The object of the invention is to make an aircraft lighter than air during construction to make it accessible without protective equipment in the gas space and / or the structural basic load during the flight test without structural changes genes to be reduced significantly.
Erfindungsgemäß wird diese Aufgabe bei einem Luftfahrzeug leichter als Luft, bei dem im Betrieb als Traggas Helium eingesetzt wird, dadurch gelöst, daß während des Baues und/oder der Flugerprobung der Traggasraum mit einem Gemisch aus Helium und einem Gas schwerer als Helium befüllt ist.According to the invention, this task is easier than air in an aircraft, in which helium is used as the carrier gas in operation, solved in that during the construction and / or flight testing of the gas space with a Mixture of helium and a gas heavier than helium is filled.
In Ausgestaltung der Erfindung beträgt der Anteil des Gases schwerer als Helium 4% (Vol.) bis 45% (Vol.).In an embodiment of the invention, the proportion of gas is heavier than helium 4% (vol.) To 45% (vol.).
Nach der Erfindung ist der Traggasraum mit einem Helium-Sauerstoff-Gemisch, einem Helium-Sauerstoff-Stickstoff-Gemisch, einem Helium-Stickstoff-Gemisch oder einem Helium-Kohlendioxyd-Gemisch befüllt.According to the invention, the gas chamber with a helium-oxygen mixture, a helium-oxygen-nitrogen mixture, a helium-nitrogen mixture or a helium-carbon dioxide mixture.
Erfindungsgemäß beträgt während des Baues der Anteil des Sauerstoffs etwa 20% (Vol.).According to the invention, the proportion of oxygen is approximately during construction 20% (vol.).
Es ist zweckmäßig, daß im Laufe der Erprobung der Anteil des Heliums vergrö ßert wird. It is advisable that the proportion of helium increases in the course of the test is ßert.
In Ausgestaltung der Erfindung wird die Erhöhung des Heliumanteiles durch eine Helium-Reinigungsanlage oder in einem Austauschverfahren erreicht. Nach Abschluß der Erprobung ist das Traggas technisch reines Helium, d. h. mit einer Reinheit von etwa 96%.In an embodiment of the invention, the increase in the proportion of helium is carried out reached a helium purification system or in an exchange process. After completion of the test, the lifting gas is technically pure helium, i. H. with a purity of about 96%.
Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert. Das Luftfahrzeug leichter als Luft, ein Luftschiff oder ein Ballon, wird während der Endmontage nicht mit technisch reinem Helium befüllt, sondern mit einem atem baren Gemisch aus Helium und Sauerstoff oder aus Helium, Sauerstoff und Stickstoff. Der Anteil des Sauerstoffs sollte 18% bis 23% (Vol.), vorzugsweise 20% bis 21% (Vol.) betragen. Wie Untersuchungen ergeben haben, entsteht eine gleichmäßige Durchmischung der beiden Gase. Eine Separierung tritt unter den gegebenen Bedingungen bei Luftschiffen nicht auf. Die Größe des Traggasrau mes und die Temperaturen beim Bau in der Halle gewährleisten ein stabiles Ge misch. In dieser atembaren Mischung können Montage- und Wartungsarbeiten im Luftschiff von Personen ohne Schutzausrüstung ausgeführt werden. Die Wahrscheinlichkeit solcher Arbeiten im Heliumraum ist beim Bau von Prototypen und Versuchsmustern von Luftschiffen relativ hoch.The invention is explained in more detail below using an exemplary embodiment. The aircraft lighter than air, an airship or a balloon, becomes during the Final assembly is not filled with technically pure helium, but with a breath a mixture of helium and oxygen or of helium, oxygen and Nitrogen. The proportion of oxygen should be 18% to 23% (vol.), Preferably 20% to 21% (vol.). As research has shown, one arises even mixing of the two gases. A separation occurs under the given conditions in airships. The size of the Traggasrau mes and the temperatures during construction in the hall ensure a stable Ge mix. Assembly and maintenance work can be carried out in this breathable mixture carried out in the airship by persons without protective equipment. the Probability of such work in the helium room is when building prototypes and test samples of airships are relatively high.
Um die strukturelle Grundbelastung im Rahmen der Erprobung des Luftschiffes möglichst gering zu halten, wird der Auftrieb durch das Traggas durch Mischung des Heliums mit Sauerstoff und/oder Stickstoff oder mit Kohlendioxyd reduziert. Zu Beginn der Erprobung beträgt der Anteil des zugemischten Gases je nach Luftschiffdesign bis zu 45% (Vol.) des Traggases. Im Laufe der Erprobung wird durch bekannte Heliumrenigungsanlagen oder im Austauschverfahren der He liumanteil erhöht bis am Ende der Erprobung technisch reines Helium den Trag gasraum ausfüllt. Unter technisch reinem Helium ist Helium mit einer Reinheit von ca. 96% zu verstehen. Der Rest sind nicht vermeidbare Verunreinigungen wie Wasserdampf und Luftreste.About the basic structural load during the testing of the airship To keep the buoyancy as low as possible, the lifting gas is mixed of helium is reduced with oxygen and / or nitrogen or with carbon dioxide. At the beginning of the test, the proportion of the mixed gas is depending on Airship design up to 45% (vol.) Of the lifting gas. In the course of testing will by known helium refining systems or in the He exchange process The proportion of technically pure helium increases the load until the end of the test gas space fills. Below technically pure helium is helium with a purity to understand by approx. 96%. The rest are unavoidable impurities like water vapor and air residues.
Bei einer Beimischung von 20% Sauerstoff ergibt sich in erster Näherung eine
Reduzierung der Auftriebsfähigkeit des Traggases um 22,4% wie folgt:
With an admixture of 20% oxygen, a first approximation results in a reduction in the buoyancy of the lifting gas by 22.4% as follows:
Das Verhältnis der Auftriebsfähigkeit beträgt:
The ratio of buoyancy is:
1 - (1,226 - 0,4062)/(1,226 - 0,169) = 22,4%
1 - (1.226-0.4062) / (1.226-0.169) = 22.4%
Abhängig vom Luftschiffdesign ergibt sich damit eine entsprechende Reduzie rung der aus der Auftriebsverteilung resultierenden Grundbelastung des Luft schiffes.Depending on the airship design, this results in a corresponding reduction tion of the base load of the air resulting from the lift distribution ship.
Die Erfindung ermöglicht durch entsprechende Beimengung eines Gases zum Helium eine Atembarkeit und damit eine Zugänglichkeit des Traggasraume ohne Schutzausrüstung und/oder eine kontrollierte Auftriebs- und damit Last verringerung zur Erprobung des Luftschiffes.The invention enables the appropriate admixture of a gas Helium breathability and thus accessibility to the lifting gas space without protective equipment and / or a controlled buoyancy and thus load reduction for testing the airship.
