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 liquefied 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, in particular in diving operation wholly or partly derive from fuel cells in which, for example, oxygen and Hydrogen is catalytically oxidized to recover electrical energy. For example, to save oxygen in sufficient amount on the boat side To be able to do that, a tank is needed in which the oxygen is in liquid Shape 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, at least for applications on land to the state of the art. Such a known tank is constructed with two shells, so it is from a pressure-tight inner wall and a distance therefrom against vacuum solid outer wall, between which Perlite is filled as radiation insulation. For thermal insulation is the gap additionally 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, a high heat insulation by arrangement of several spaced aluminum foils and to reach intermediate evacuated rooms.

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, because they have only a small mechanical load, as for example in an impact or a detonation occur, stand 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 continues to be state of the art in vehicles bivalve liquid oxygen tanks between the inner and outer wall Provide bands that the walls even in the case of load Keep apart from each other. But these are also the constructions not for use in a military submarine suitable because the loads, for example, during detonation a water bomb near the submarine arise in the area of which are ten to a hundred times the gravitational acceleration (10 to 100 g). Although it would be constructively conceivable, the known construction, on the inner wall and outer wall via bands with each other so far as to reinforce that such a mechanical Could be absorbed, but would be so large strip cross-sections reveal that the required insulation between Interior and exterior wall would no longer be feasible, as the Thermal bridges through the bands 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 LPG, especially of liquid oxygen, to create, in which as well the tank the submarine specific in particular military requirements 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 Characteristics solved. Advantageous embodiments of the invention are in the subclaims, the following description and the drawing indicated.

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, in particular liquid Oxygen, equipped, which is built up two-shell, the between Inner wall and outer wall with packing for radiation insulation is provided, the heat conduction insulation between the outer wall and inner wall is evacuated and in addition the holding means intended for mechanical connection of outer wall and inner wall are what the insulating effect of the container does not have the required Affect the measure. The retaining means are however in With regard to their dimensioning designed only for a static load, that is, around the inner container formed by the inner wall within the outer container formed by the outer wall as intended to keep. To the submarine-specific military Requirements, in particular with regard to the shock load, To be able to absorb, the invention provides filler body, which is substantially Have spherical shape. These fillers are therefore not only for Radiation insulation, as is well known, but they serve in particular for absorbing high shock loads, without losing the Insulation effect (even during the shock load) strongly influence. Due to the spherical shape of the packing - it does not have to be geometric ideal spherical shape can be realized, it is sufficient approximate Ball shape - in case of shock load occurring Forces are largely evenly distributed over the balls, in particular in the dimensioning according to the invention, the balls in behave like a solid body and thus 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.Particularly suitable for this are glass beads, since 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 embodiment of the invention, the glass beads are not solid, but designed as a hollow body. This will in particular the insulating effect increased 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.Preference is given as a packing according to the invention micro glass beads used, which have liquid-like flow behavior as bulk material, So get into tight spaces and thus manufacturing technology particularly favorable in between the inner wall and outer wall formed free space are fillable. These glass microspheres are distributed liquid-like in the formed between the outer wall and inner wall Freiraum, however, act in case of sudden load, as they For example, by the pressure wave at a detonation occurs, similar like a solid. They thus fix the inner container with the required distance to the outer container and ensure the required Insulation even in case of stress. Although is in the load case the thermal conductivity of the microglass spheres due to the higher surface pressure between the balls slightly larger, but this takes after dropping the load to the same extent again.

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 filling bodies of different Material and different sizes exist, but are preferred Microglass balls with a mean diameter of 20 to 120 used, in compressed form. By compacting the in the space filled filler becomes a higher packing density and thus achieved a higher stability. The compacting can be done by means of a known shaking device. To the To further reduce the thermal conductivity of the glass microspheres, these are advantageous not designed as a solid but as a hollow balls and have a wall thickness, depending on the pressure requirement between 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 lsolierwirkung zwischen Innen- und Außenbehälter durch die Bänder vergleichsweise wenig verschlechtert wird.The structural design of the liquid oxygen tank according to the invention is, at least as far as the holding means between the inner and outer tanks As far as is relatively simple, as they are essentially for recording the static loads acting between the inner wall and the outer wall designed and designed. The holding means are therefore only under normal static conditions, the inner tank in its position to keep the outer tank. You do not need for an increased (dynamic) load to be designed, which is not only constructive is advantageous, but also has advantages in terms of insulation. Namely, the holding means may be in the form of, for example, crosswise strained elongated ribbons between inner wall and outer wall be formed. Such an arrangement is particularly advantageous because then the inner tank formed by the inner wall almost within the outer tank formed by the outer wall suspended can be, d. H. the retaining elements are only tensioned. These then do not need to be trained strangely and can one have comparatively small cross-section, so that the insulating effect between inner and outer containers by the bands comparatively little is worsened.

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 a filling of the liquid oxygen in the tank and a removal Allowing liquid oxygen from the tank is at least to provide a line penetrating the tank and corresponding Shut-off, 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 under pressure and stored refrigerated, the Submarine specific requirements regarding shock loading and Storage time (for example, over a week) without additional facilities can be achieved for heat dissipation.

Der anhand der Figuren dargestellte Tank 1 für die Lagerung von flüssigem Sauerstoff auf einem militärischen U-Boot ist an geeigneter (nicht dargestellter) Stelle im U-Boot angeordnet, dies kann innerhalb oder außerhalb des Druckraumes sein. Der Tank 1 weist eine Innenwand 2 auf, welche ein druckdichtes Innenbehältnis (Innentank) bildet, in dem der Sauerstoff 3 gelagert ist. In den Figuren ist mit 3a der flüssige Sauerstoff und mit 3b der gasförmige Anteil innerhalb des Tanks 1 gekennzeichnet. Die Innenwand 2 ist zu einem im Wesentlichen zylindrischen und an den Enden etwa halbkugelförmigen Innenbehälter geformt, der allseits mit im Wesentlichen konstanten Abstand 4 zu einer Außenwand 5 angeordnet ist, die ein äußeres Behältnis (Außentank) bildet, das die gleiche Form wie der Innentank aufweist, jedoch deutlich größer ist, um diesen mit Abstand 4 zu umgeben.The illustrated with reference to the figures tank 1 for the storage of liquid Oxygen on a military submarine is more appropriate (not Placed in the submarine, this can be inside or be outside the pressure chamber. The tank 1 has an inner wall 2 on, which forms a pressure-tight inner container (inner tank), in the the oxygen 3 is stored. In the figures, 3a is the liquid oxygen and 3b, the gaseous fraction within the tank 1. The inner wall 2 is a substantially cylindrical and formed at the ends about hemispherical inner container, the on all sides with a substantially constant distance 4 to an outer wall 5 is arranged, which forms an outer container (outer tank), which is the has the same shape as the inner tank, but significantly larger to surround it with distance 4.

Der durch die Innenwand 2 gebildete Innenbehälter ist über Tragbänder 6 innerhalb des durch die Außenwand 5 gebildeten Außenbehälters aufgehängt. Die Tragbänder 6 sind an mindestens sechs Seiten angeordnet, und zwar jeweils paarweise und gekreuzt um diese möglichst lang ausbilden zu können. Die Bänder 6 sind so ausgelegt, dass sie im Wesentlichen die statische Last tragen, welche der mit Sauerstoff gefüllte Innenbehälter insbesondere durch seine Gewichtskraft erzeugt. Die Bänder 6 sind ebenso wie die Innen- und Außenbehälter aus Stahl gebildet und mit diesen verschweißt. The inner container formed by the inner wall 2 is via straps 6 within the outer container 5 formed by the outer wall suspended. The straps 6 are arranged on at least six sides, in pairs and crossed around these as possible to be able to train long. The bands 6 are designed so that they are in Essentially carry the static load, which is the one filled with oxygen Inner container generated in particular by its weight. The Belts 6 are formed as well as the inner and outer containers made of steel and welded to them.

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 inner wall 2 and outer wall 5 is with Microglass balls 7 completely filled, in addition to this Space have been compacted. The so with compacted glass microspheres 7 filled room is then evacuated, d. H. placed under vacuum been made in order to achieve a high insulation effect in this way. Due to the compression and evacuation of the microglass balls 7 are resistant to abrasion packed, so that even in normal operation no wear arises within the insulation. They take in case of shock for example, in the amount of 10 to 100 g occurring forces on, without the straps 6 are also noticeably burdened. The insulation effect remains almost completely preserved completely restored immediately after loading.

Zum Befüllen und Entleeren des flüssigen Sauerstoffs ist nahe dem Boden des Tanks 1 eine die Innenwand 2 und die Außenwand 5 durchdringende Leitung 8 vorgesehen sowie ein Absperrventil 9, dass symbolisch für die hier gegebenenfalls noch vorzusehenden Sicherheits- und Ventilanordnungen steht. To fill and empty the liquid oxygen is near the bottom of the tank 1 a the inner wall 2 and the outer wall 5 penetrating Line 8 provided as well as a shut-off valve 9 that symbolically for the here still to be provided security and Valve arrangements is.
