Abstract
Description
Die Erfindung betrifft ein Unterseeboot mit einem Tank zur Aufnahme und Lagerung von Flüssiggas, insbesondere Sauerstoff.The invention relates to a submarine with a tank for receiving and storage of liquid gas, especially oxygen.
Unterseeboote, insbesondere für den militärischen Einsatz, können ihre elektrische Energie, insbesondere im Tauchbetrieb ganz oder teilweise aus Brennstoffzellen beziehen, in denen beispielsweise Sauerstoff und Wasserstoff zur Gewinnung elektrischer Energie katalytisch oxidiert wird. Um beispielsweise Sauerstoff in ausreichender Menge bootsseitig speichern zu können, ist ein Tank erforderlich, in dem der Sauerstoff in flüssiger Form gelagert werden kann.Submarines, especially for military use, can be theirs electrical energy, especially in diving operation in whole or in part obtain from fuel cells in which, for example, oxygen and Hydrogen is catalytically oxidized to generate electrical energy. For example, to store enough oxygen on the boat side To be able to, a tank is required in which the oxygen is in liquid Form can be stored.
Die Lagerung von tiefkaltem flüssigem Gas, insbesondere von Sauerstoff, zählt zumindest bei Anwendungen an Land zum Stand der Technik. Ein solcher bekannter Tank ist zweischalig aufgebaut, besteht also aus einer druckdichten Innenwand sowie einer mit Abstand dazu angeordneten gegen Vakuum feste Außenwand, zwischen denen Perlite als Strahlungsisolierung verfüllt ist. Zur Wärmleitungsisolierung ist der Zwischenraum zusätzlich auch evakuiert.The storage of cryogenic liquid gas, especially oxygen, is state of the art, at least for applications on land. Such a known tank is constructed with two shells, so it exists from a pressure-tight inner wall and a spaced one external wall solid against vacuum, between which perlite is filled in as radiation insulation. The space is for thermal insulation also evacuated.
Weiterhin ist es bekannt, eine hohe Wärmeisolation durch Anordnung von mehreren mit Abstand zueinander angeordneten Alufolien und dazwischen befindlichen evakuierten Räumen zu erreichen.Furthermore, it is known to provide high thermal insulation by arrangement of several aluminum foils and spaced apart to reach the evacuated rooms in between.
Diese Anordnungen sind jedoch nur für die stationäre Anwendung geeignet, da sie nur in geringem Maße mechanischen Lasten, wie sie beispielsweise bei einen Aufprall oder einer Detonation auftreten, Stand halten.However, these arrangements are only suitable for stationary use, since they only have a small mechanical load, such as that in the event of an impact or a detonation, status hold.
Es zählt weiter zum Stand der Technik bei auf Fahrzeugen angeordneten zweischaligen Flüssigsauerstofftanks zwischen der Innen- und Außenwand Bänder vorzusehen, welche die Wandungen auch im Belastungsfalle mit Abstand zueinander halten. Doch sind auch diese Konstruktionen für den Einsatz in einem militärischen Unterseeboot nicht geeignet, da die Belastungen, die beispielsweise bei der Detonation einer Wasserbombe in der Nähe des Unterseebootes entstehen, im Bereich von dem zehn- bis hundertfachen der Erdbeschleunigung liegen (10 bis 100 g). Zwar wäre es konstruktiv denkbar, die bekannte Konstruktion, bei der Innenwand und Außenwand über Bänder miteinander verbunden sind, soweit zu verstärken, dass eine solche mechanische Belastung aufgenommen werden könnte, doch würden sich hierbei so große Bandquerschnitte ergeben, dass die erforderliche Isolierung zwischen Innen- und Außenwand nicht mehr realisierbar wäre, da die Wärmebrücken durch die Bänder die Isolierung unwirksam machen.It also belongs to the state of the art for vehicles double-shell liquid oxygen tanks between the inner and outer wall To provide tapes that cover the walls even in the event of stress keep at a distance from each other. But these are also constructions not for use in a military submarine suitable because the loads, for example during detonation a water bomb will arise near the submarine in the area are ten to one hundred times the gravitational acceleration (10 to 100 g). It would be conceivable in terms of construction, the known construction, with the inner wall and outer wall with bands are connected to the extent that such a mechanical Load could be absorbed, but this would be so large strip cross sections result in the necessary insulation between Interior and exterior wall would no longer be feasible, since the Thermal bridges through the tapes render the insulation ineffective.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Unterseeboot mit einem Tank zur Aufnahme und Lagerung von Flüssiggas, insbesondere von flüssigen Sauerstoff, zu schaffen, bei dem auch der Tank den U-Boot spezifischen insbesondere militärischen Anforderungen genügt.Against this background, the invention is based on the object Submarine with a tank for holding and storing liquid gas, especially of liquid oxygen, to create that too the tank the submarine specific military requirements in particular enough.
Diese Aufgabe wird gemäß der Erfindung durch die in Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen, der nachfolgenden Beschreibung sowie der Zeichnung angegeben.This object is achieved according to the invention by those specified in claim 1 Features solved. Advantageous embodiments of the invention are in the subclaims, the description below as well as the drawing.
Gemäß der vorliegenden Erfindung ist das Unterseeboot mit einem Tank zur Aufnahme und Lagerung von Flüssiggas, insbesondere von flüssigem Sauerstoff, ausgestattet, der zweischalig aufgebaut ist, der zwischen Innenwand und Außenwand mit Füllkörpern zur Strahlungsisolierung versehen ist, der zur Wärmeleitungsisolierung zwischen Außenwand und Innenwand evakuiert ist und bei dem darüber hinaus Haltemittel zum mechanischen Verbund von Außenwand und Innenwand vorgesehen sind, welche die Isolierwirkung des Behälters nicht über das erforderliche Maß hinaus beeinträchtigen. Die Haltemittel sind jedoch im Hinblick auf ihre Dimensionierung lediglich auf eine statische Last ausgelegt, also um den durch die Innenwand gebildeten Innenbehälter innerhalb des durch die Außenwand gebildeten Außenbehälters bestimmungsgemäß zu halten. Um die unterseebootspezifischen militärischen Anforderungen, insbesondere hinsichtlich der Schockbelastung, aufnehmen zu können, sieht die Erfindung Füllkörper vor, die im Wesentlichen Kugelform aufweisen. Diese Füllkörper dienen also nicht nur zur Strahlungsisolierung, wie dies an sich bekannt ist, sondern sie dienen insbesondere zur Aufnahme hoher Schockbelastungen, ohne dabei die Isolationswirkung (auch während der Schockbelastung) stark zu beeinflussen. Durch die Kugelform der Füllkörper - es muss hier keine geometrisch ideale Kugelform realisiert werden, es genügt eine angenäherte Kugelform - werden im Falle einer Schockbelastung die auftretenden Kräfte über die Kugeln weitgehend gleichmäßig verteilt, wobei insbesondere bei der erfindungsgemäßen Dimensionierung sich die Kugeln in ihrer Gesamtheit festkörperartig verhalten und somit sehr hohe Kräfte aufnehmen können.According to the present invention, the submarine is with a Tank for holding and storing liquid gas, especially liquid gas Oxygen, equipped, the double-shell structure, the between Inner wall and outer wall with fillings for radiation insulation is provided for thermal insulation between the outer wall and inner wall is evacuated and in addition to the holding means intended for the mechanical connection of the outer wall and inner wall are, which the insulating effect of the container does not exceed the required Affect dimension beyond. However, the holding means are in the Designed only for a static load in terms of their dimensions, thus around the inner container formed by the inner wall as intended within the outer container formed by the outer wall to keep. To the submarine-specific military Requirements, especially with regard to the shock load, To be able to accommodate, the invention provides packing, which essentially Have spherical shape. These fillers are not only used for Radiation isolation, as is known per se, but they serve especially to absorb high shock loads without losing the To strongly influence the insulation effect (also during the shock load). Due to the spherical shape of the packing - there does not have to be any geometrical here ideal spherical shape can be realized, an approximate one is sufficient Spherical shape - in the event of a shock load, those that occur Forces distributed largely evenly over the balls, in particular in the dimensioning according to the invention the balls in behave as a solid and therefore very high forces be able to record.
Besonders geeignet hierfür sind Glaskugeln, da sie extrem formstabil sind, kostengünstig hergestellt werden können und sehr hohe Kräfte aufnehmen können.Glass balls are particularly suitable for this because they are extremely dimensionally stable are, can be produced inexpensively and very high forces be able to record.
In vorteilhafter Weiterbildung der Erfindung sind die Glaskugeln nicht massiv, sondern als Hohlkörper ausgebildet. Hierdurch wird insbesondere die Isolierwirkung gesteigert ohne merkliche Stabilitätseinbußen zu haben.In an advantageous development of the invention, the glass balls are not massive, but formed as a hollow body. This will in particular the insulation effect increases without noticeable loss of stability to have.
Bevorzugt werden als Füllkörper gemäß der Erfindung Mikroglaskugeln eingesetzt, die als Schüttgut flüssigkeitsähnliches Fließverhalten haben, also auch in enge Zwischenräume gelangen und somit fertigungstechnisch besonders günstig in den zwischen Innenwand und Außenwand gebildeten Freiraum verfüllbar sind. Diese Mikroglaskugeln verteilen sich flüssigkeitsähnlich in dem zwischen Außenwand und Innenwand gebildeten Freiraum, wirken jedoch im Falle plötzlicher Belastung, wie sie beispielsweise durch die Druckwelle bei einer Detonation auftritt, ähnlich wie ein Festkörper. Sie fixieren somit den Innenbehälter mit dem erforderlichen Abstand zum Außenbehälter und gewährleisten die erforderliche Isolierung auch im Belastungsfall. Zwar wird im Belastungsfall die Wärmeleitfähigkeit der Mikroglaskugeln aufgrund der höheren Flächenpressung zwischen den Kugeln gringfügig größer, doch nimmt diese nach Abfall der Belastung im gleichen Maße wieder ab.Micro-glass spheres are preferred as packing elements according to the invention used as bulk material with liquid-like flow behavior, So also get into narrow spaces and thus in terms of production technology particularly favorable in the between the inner wall and outer wall formed space can be filled. These micro glass balls spread out liquid-like in that formed between the outer wall and the inner wall Free space, however, in the case of sudden stress, they work like they do for example by the pressure wave occurring during a detonation, similar like a solid. You thus fix the inner container with the required distance to the outer container and ensure the required Insulation even in the event of a load. Although in case of stress the thermal conductivity of the micro glass balls due to the higher surface pressure between the balls slightly larger, but this takes after the load has dropped to the same extent.
Je nach Anwendungsfall können die Füllkörper aus unterschiedlichem Material und unterschiedlicher Größe bestehen, bevorzugt werden jedoch Mikroglaskugeln mit einem mittleren Durchmesser von 20 bis 120 µm eingesetzt, und zwar in verdichteter Form. Durch das Verdichten der in den Zwischenraum eingefüllten Füllkörper wird eine höhere Packungsdichte und somit eine höhere Stabilität erreicht. Das Verdichten kann mittels einer an sich bekannten Rütteleinrichtung erfolgen. Um die Wärmeleitfähigkeit der Mikroglaskugeln weiter zu verringern, sind diese vorteilhaft nicht als Vollkörper sondern als Hohlkugeln ausgebildet und weisen eine Wanddicke auf, die je nach Druckanforderung zwischen 0,2 und 5 µm liegt.Depending on the application, the packing can be made of different materials Material and different sizes exist, but are preferred Micro glass balls with an average diameter of 20 to 120 µm used, and that in compressed form. By compressing the Filled bodies filled into the space will have a higher packing density and thus achieved a higher stability. The condensing can be done by means of a vibrating device known per se. To the These are to further reduce the thermal conductivity of the micro glass balls advantageously not designed as a solid body but as hollow spheres and have a wall thickness that, depending on the pressure requirement 0.2 and 5 microns.
Die konstruktive Ausbildung des erfindungsgemäßen Flüssigsauerstofftanks ist, zumindest soweit es die Haltemittel zwischen Innen- und Außentank angeht, relativ einfach, da sie im Wesentlichen zur Aufnahme der zwischen Innenwand und Außenwand wirkenden statischen Lasten ausgelegt und ausgebildet ist. Die Haltemittel dienen also lediglich dazu, unter normalen statischen Bedingungen den Innentank in seiner Position zum Außentank zu halten. Sie brauchen nicht für eine erhöhte (dynamische) Belastung ausgelegt zu werden, was nicht nur konstruktiv von Vorteil ist, sondern auch hinsichtlich der Isolierwirkung Vorteile hat. Die Haltemittel können nämlich in Form von beispielsweise kreuzweise verspannten lang gestreckten Bändern zwischen Innenwand und Außenwand gebildet sein. Eine solche Anordnung ist besonders vorteilhaft, da dann der durch die Innenwand gebildeten Innentank quasi innerhalb des durch die Außenwand gebildeten Außentanks aufgehängt werden kann, d. h. die Halteelemente nur zugbelastet werden. Diese brauchen dann nicht eigensteif ausgebildet zu sein und können einen vergleichsweise geringen Querschnitt aufweisen, so dass die Isolierwirkung zwischen Innen- und Außenbehälter durch die Bänder vergleichsweise wenig verschlechtert wird.The design of the liquid oxygen tank according to the invention is, at least as far as the holding means between the inner and outer tank is relatively easy since it is essentially for recording the static loads acting between the inner wall and the outer wall is designed and trained. The holding means therefore only serve to the normal position of the inner tank under normal static conditions to hold to the outside tank. You don't need an elevated one (dynamic) load to be designed, which is not just constructive is advantageous, but also has advantages with regard to the insulating effect. The holding means can namely in the form of, for example, crosswise stretched elongated ligaments between the inner wall and outer wall be educated. Such an arrangement is particularly advantageous since then the inner tank formed by the inner wall virtually inside of the outer tank formed by the outer wall can be d. H. the holding elements are only subjected to tensile loads. This then do not need to be designed to be rigid and can have a comparatively small cross-section, so that the insulating effect comparatively between the inner and outer container through the straps little deteriorates.
Um ein Befüllen des flüssigen Sauerstoffs in den Tank und eine Entnahme von flüssigen Sauerstoff aus dem Tank zu ermöglichen, ist mindestens eine den Tank durchdringende Leitung vorzusehen sowie entsprechende Absperrmittel, in Form eines Absperrventils, eines Überdruckventils und dergleichen.To fill the liquid oxygen into the tank and take it out to allow liquid oxygen from the tank is at least to provide a line penetrating the tank and corresponding Shut-off means, in the form of a shut-off valve, a pressure relief valve and the same.
Mit der erfindungsgemäßen Lösung kann flüssiges Gas, insbesondere flüssiger Sauerstoff unter Druck und gekühlt gelagert werden, wobei die U-Boot spezifischen Anforderungen hinsichtlich Schockbelastung und Lagerungszeit (beispielsweise über eine Woche) ohne zusätzliche Einrichtungen zur Wärmeabfuhr erzielt werden können.With the solution according to the invention, liquid gas, in particular liquid oxygen is stored under pressure and refrigerated, the Submarine specific requirements regarding shock load and Storage time (for example over a week) without additional facilities can be achieved for heat dissipation.

Der zwischen Innenwand 2 und Außenwand 5 gebildete Raum ist mit
Mikroglaskugeln 7 vollständig gefüllt, die darüber hinaus in diesem
Raum verdichtet worden sind. Der so mit verdichteten Mikroglaskugeln
7 ausgefüllte Raum ist danach evakuiert, d. h. unter Vakuum gesetzt
worden, um auf diese Weise eine hohe Isolierwirkung zu erreichen.
Durch die Verdichtung und Evakuierung sind die Microglaskugeln 7 abriebfest
gepackt, so dass auch im normalen Betrieb keinerlei Verschleiß
innerhalb der Isolierung entsteht. Sie nehmen die im Falle einer Schockbelastung
beispielsweise in Höhe von 10 bis 100 g auftretenden Kräfte
auf, ohne dass die Tragbänder 6 zusätzlich merklich belastet werden.
Die Isolationswirkung bleibt dabei nahezu vollständig erhalten bzw. wird
unmittelbar nach der Belastung vollständig wieder hergestellt.The space formed between the
