[0054] In the following description of various embodiments of the container 10 in accordance with the invention for receiving and storing liquids and viscous materials, particularly cryogenic fluids, and of methods for the production thereof, similar components that correspond to each other are each provided with identical reference numbers.

[0055] The container 10 for receiving and storing liquids and viscous materials, particularly cryogenic fluids, preferably oxygen and hydrogen, is used in an advantageous manner in vehicles, particularly in aerodynes or aircraft for application in aeronautics, preferably in aeroplanes and space aerodynes, particularly in water vehicles, preferably in a submarine or air cushion craft (Hovercraft), or particularly in land vehicles, preferably in a passenger vehicle, truck or caravan, particularly for receiving and storing of liquids and viscous materials, particularly of cryogenic fluids, for rocket propellant tanks and satellite tanks. The container 10 in accordance with the invention is particularly suited for rocket propellant tanks and satellite tanks, to receive and store liquids and viscous materials, particularly of cryogenic fluids, and gaseous, liquid and solid materials, preferably fuels or propellants, such as hydrazine, monomethylhydrazine (MMH), unsymmenrical dimethlyhydrazine (UDMH) or kerosine, oxidizing agents (oxidizers), such as nitrogen tetroxides or dinitrogen tetroxides (NTO), or fuel/oxidizer mixes and/or (drinking) water and waste water, for tanks and fuel tanks of rockets and/or satellites.

[0056] The container 10 according to the invention shown in schematic view in FIG. 1 comprises a, in particular thin-walled, casing 12, which forms the interior space 14 of the container 10 with at least one chamber 16. In the chamber 16 are received and stored, for example, cryogenic fluids such as oxygen (LOX) and hydrogen (LH2) that are used as fuel/oxidator mixture in an upper stage of a carrier rocket (not shown).

[0057] The containers 10 according to the invention schematically shown in FIGS. 2A and 2B comprise a, in particular thin-walled, casing 12 and at least one bulkhead 18. The at least one bulkhead 18 divides the interior space 14 of the container 10 into at least two chambers 16, 16′ adjacent to each other. In the chambers 16, 16′ are received and stored, for example, cryogenic fluids such as oxygen (LOX) and hydrogen (LH2) that are used as fuel/oxidator mixture in an upper stage of a carrier rocket (not shown).

[0058] According to FIGS. 2A and 2B, both containers 10 each have only one single bulkhead 18 for dividing the interior space 16 into two separate chambers 16, 16′. Both chambers 16, 16′ of the container 10 share the common bulkhead 18.

[0059] The embodiments of the container 10 according to the invention shown in FIGS. 2A and 2B only differ in the design of the bulkhead 18 itself respectively the arrangement of the bulkhead 18 within the casing 12 of the container 10. This means that under the embodiment of the container 10 shown in FIG. 2A, the bulkhead 18 is designed in a concave shape. Under the embodiment of the container 10 shown in FIG. 2B, on the other hand, the bulkhead 18 is designed in a convex shape. Apart from that, the two embodiments of the bulkhead 18 of the container 10 according to the invention in accordance with FIGS. 2A and 2B have an identical structural design.

[0060] The embodiment of the container 10 according to the invention in accordance with FIG. 1 is formed of at least two container structures 20, 20′ or 20′, 20″ respectively, one of which is shown in FIGS. 3 and 4.

[0061] The embodiments of the container 10 according to the invention in accordance with FIGS. 2A and 2B, on the other side, are each formed of at least three container structures 20, 20′, 20″, one of which is shown in FIGS. 3 and 4.

[0062] As can be seen in FIGS. 3 and 4, the container structure(s) 20, 20′, 20″ is/are each deformed from a blank (not shown) as a single part. The container structure(s) 20, 20′, 20″ each has/have a dome section 22, a branch section 24 attaching to the dome section 22, and two cylinder sections 26, 28 attaching to the branch section 24.

[0063] Without being shown in detail, the adjacent facing container structures 20, 20′, or 20′, 20″ respectively, of the container structures 20, 20′, 20″ are joined together to form the container 10, the container 10 comprising a chamber 16 according to FIG. 1, or, according to the examples of embodiment shown in FIGS. 2A to 8L, a bulkhead 18 to form two chambers 16, 16′.

[0064] The container structures 20, 20′, or 20′, 20″ respectively, adjacent to each other are joined together directly and/or indirectly via at least one other, additional cylinder element 46, 46′ (as already shown in FIG. 9). Here, the container structures 20, 20′, or 20′, 20″ respectively, adjacent to each other and/or the at least one other cylinder element 46, 46′ are preferably flow turned and/or spun or welded together.

[0065] Furthermore, the container 10, in particular the at least two or three container structures 20, 20′, 20″ and/or the at least one other cylinder element 46, 46′ of the container 10, is/are designed in a lightweight way. Preferably these are made of metal, in particular of steel, stainless steel, aluminium, titanium, an alloy of those and/or a combination of those.

[0066] The dome section 22 of the container structure(s) 20, 20′, 20″ is each designed in a cup shape, in particular in a hemi-spherical, spherical cup, dome, ellipsoid dome, conical, elliptic, Cassini shape or in any other cross-sectional shapes. The cylinder section(s) 26, 28 of the container structure(s) 20, 20′, 20″ and/or the at least one other cylinder element 46, 46′ of the container 10 are reinforced. In a beneficial way, reinforcements 30 are provided in the form of (stiffening) ribs, ribs, reinforcing ribs, stringers and/or isogrid or orthogrid structures.

[0067] The production of the embodiments of the container 10 according to the invention shown in FIGS. 1 to 4 is explained in more detail below by example of FIGS. 5A to 5J, alternatively of FIGS. 6A to 6L:

[0068] According to FIGS. 5A to 5J, one embodiment of a method according to the invention for producing a container 10 comprises the following steps:

[0069] According to FIGS. 5A and 5B a blank 32 is provided. The blank 32 is preferably flat, planar or largely planar or of similar shape. Preferably, the blank 32 is essentially circular or disk-shaped or circular or disk-shaped. In particular, the blank 32 is machined from a planar blank (not shown), for example from a cut piece of sheet metal or similar material by cutting, in particular by mechanical cutting, laser or water jet cutting, sawing, milling or eroding.

[0070] Preferably, before that the blank 32 is (pre-)contoured and/or pre-contoured or contoured by machining, in particular by turning, milling and/or grinding. It is also possible, however, to produce the actual blank 32 with a contouring. For example, the blank 32 can also be formed by rolling.

[0071] Then the blank 32 is clamped onto or into at least one support structure or spin chuck 34.

[0072] According to FIGS. 5C and 5D, the blank 32 is deformed by spin forming and/or turning using the support structure or spin chuck 34 into a dome section 22 of a container structure 20, 20′, 20″ or provided with a dome section 22. In the embodiment of the method according to the invention shown in FIGS. 5A to 5J, convex spin forming and/or turning is used.

[0073] As can be seen in FIGS. 5C and 5D, the spin chuck 34 has integrated grooves 36 or similar structures to form the reinforcements 30, preferably on the inside, on the container structure(s) 20, 20′, 20″ at a later stage.

[0074] According to FIGS. 5E and 5F, an additional spin chuck 38 is attached after the convex spin forming. Accordingly, the blank 32 and/or the container structure 20, 20′, 20″ is clamped onto or into the at least one support structure or spin chuck 34 and another support structure or spin chuck 38 acting in conjunction with it. The spin chuck 38 forms a counter support causing a clamping of the container structure 20, 20′, 20″ or of its previously formed dome section 22.

[0075] According to FIGS. 5G and 5H, subsequently an edge 40 or the material protruding over the spin chucks 32, 38 at the edge of the blank 32 is deformed into a branch section 24 attaching to the dome section 22 and two essentially radially extending cylinder sections 26′, 28′ of the container structure 20 that are attaching to the branch section 24 through splitting by means of a splitting roller (not shown) acting on the edge 40 of the blank 32. The splitting roller acting on the edge 40 of the blank 32 has, for example, an essentially cone-shaped, diamond-shaped or sharp-edged cross-section, as the case may be with an additional rounding.

[0076] According to FIGS. 5I and 5J, then the two essentially radially extending cylinder sections 26′, 28′ of the container structure 20 that are attaching to the branch section 24 are flow turned and/or spun into two axially extending cylinder sections 26, 28, that is the upper cylinder section 26 and the lower cylinder section 28, of the container structure 20.

[0077] Where the support structure or spin chuck 34 and/or the other support structure or spin chuck 38 has/have corresponding negative contours, at the same time the reinforcements 30, for example in the form of (stiffening) ribs, ribs, reinforcing ribs, stringers and/or isogrid or orthogrid structures, and/or other—also (partially) smooth-walled—structures can be generated in the cylinder section(s) 26, 28, on the outside and/or inside, preferably on the inside, during flow turning or flow pressing and/or spinning.

[0078] Finally, the two axially extending cylinder sections 26, 28, that is the upper cylinder section 26 and the lower cylinder section 28, of the container structure 20 can be deformed into their desired length during an additional flow turning or flow pressing and/or spinning and/or stretching process.

[0079] Subsequently, at least one or two additional container structure(s) 20′, 20″ according to steps a) to e) is/are formed.

[0080] Thereafter, the adjacent facing container structures 20, 20′, or 20′, 20″ of the container structures 20, 20′, 20″ respectively, are joined together into a container 10. This can be done by directly joining together the container structures 20, 20′, or 20′, 20″ respectively, adjacent to each other. In an alternative or additional manner, it is also conceivable to indirectly join together the container structures 20, 20′, or 20′, 20″ respectively, adjacent to each other introducing at least one other cylinder element 46, 46′ (see FIG. 9).

[0081] The joining together of the container structures 20, 20′, or 20′, 20″ respectively, adjacent to each other and/or of the at least one further cylinder element 46, 46′ is preferably achieved by flow turning or flow pressing and/or spin welding. A beneficial alternative is also welding, preferably friction stir welding (FSW).

[0082] According to FIGS. 6A to 6L, another embodiment of a method according to the invention for producing a container 10 cornprises the following steps:

[0083] According to the embodiment shown in FIGS. 6A and 6B, a blank is provided that is designed preferably according to the embodiment in accordance with FIGS. 5A to 5J. Accordingly, the blank 32 is in particular flat, planar or largely planar or of similar shape and/or essentially circular or disk-shaped or circular or disk-shaped. As in the above example of embodiment of FIGS. 5A to 5J, the blank 32 is machined from a planar blank (not shown) that is (pre-)contoured and/or pre-contoured or contoured. However, it is also absolutely conceivable to integrate a contouring into the blank 32.

[0084] According to FIGS. 6C and 6D, the provided blank 32 is clamped onto or into the at least one support structure or spin chuck 34. Then another support structure or spin chuck 38 is attached. Accordingly, the blank 32 is clamped onto or into the support structure or spin chuck 34 and the other support structure or spin chuck 38 acting in conjunction with it. The spin chuck 38 forms a counter support causing a clamping of the blank 32.

[0085] According to FIGS. 6E and 6F, subsequently an edge 40 or the material protruding over the spin chucks 32, 38 at the edge of the blank 32 is deformed into a branch section 24 and two essentially radially extending cylinder sections 26′, 28′ of a container structure 20 that are attaching to the branch section 24. The deforming is achieved through splitting by means of a splitting roller (not shown) acting on the edge 40 of the blank 32. The splitting roller acting on the edge 40 of the blank 32 has, for example, an essentially cone-shaped, diamond-shaped or sharp-edged cross-section, as the case may be with an additional rounding.

[0086] According to FIGS. 6G and 6H, then the two essentially radially extending cylinder sections 26′, 28′ of the container structure 20 that are attaching to the branch section 24 are flow turned and/or spun into two axially extending cylinder sections 26, 28, that is the upper cylinder section 26 and the lower cylinder section 28, of the container structure 20.

[0087] Where the support structure or spin chuck 34 and/or the other support structure or spin chuck 38 has/have corresponding negative contours, now or later the reinforcements 30, for example in the form of (stiffening) ribs, ribs, reinforcing ribs, stringers and/or isogrid or orthogrid structures, and/or other, also (partially) smooth-walled, structures can be generated in the cylinder section(s) 26, 28, on the outside and/or inside, preferably on the inside, during flow turning or flow pressing and/or spinning.

[0088] According to FIGS. 6I and 6J, now the blank 32 is deformed by spin forming and/or turning into a dome section 22 of the container structure 20 attaching to the branch section 24. In the embodiment of the method according to the invention shown in FIGS. 6A to 6L, concave spin forming or turning by means of another support structure or spin chuck 42 is provided.

[0089] According to FIGS. 6K and 6L, finally the two axially extending cylinder sections 26, 28, that is the upper cylinder section 26 and the lower cylinder section 28, of the container structure 20 can be deformed into their desired length during an additional flow turning or flow pressing and/or spinning and/or stretching process.

[0090] As an alternative to the step according to FIGS. 6G and 6H, it is possible during the process to provide the reinforcements 30, for example in the form of (stiffening) ribs, ribs, reinforcing ribs, stringers and/or isogrid or orthogrid structures, and/or other, also (partially) smooth-walled, structures in the cylinder section(s) 26, 28, on the outside and/or inside, preferably on the inside, during flow turning or flow pressing and/or spinning.

[0091] Subsequently, at least one or two additional container structure(s) 20′, 20″ according to steps a) to e) is/are formed.

[0092] Thereafter, the adjacent facing container structures 20, 20′, or 20′, 20″ respectively, of the at least three container structures 20, 20′, 20″ are joined together into a container 10. This can be done by directly joining together the container structures 20, 20′, or 20′, 20″ respectively, adjacent to each other. In an alternative or additional manner, it is also conceivable to indirectly join together the container structures 20, 20′, or 20′, 20″ respectively, adjacent to each other introducing at least one other cylinder element 46, 46′ (shown in FIG. 9).

[0093] The joining together of the container structures 20, 20′, or 20′, 20″ respectively, adjacent to each other and/or of the at least one other cylinder element 46, 46′ is preferably achieved by flow turning or flow pressing and/or spin welding. A beneficial alternative is also welding, in particular friction stir welding (FSW).

[0094] Additionally, the production of the embodiments of the container 10 according to the invention shown in FIGS. 1 to 4 is also realized through other methods according to the invention which are shown schematically in FIGS. 7A to 7J and alternatively in FIGS. 8A to 8L.

[0095] The embodiment of the method according to the invention in accordance with FIGS. 7A to 7J differs from that shown in FIGS. 5A to 5J in that in step a) instead of a blank 32 that is flat, planar or largely planar or of similar shape, preferably essentially circular or disk-shaped, or circular or disk-shaped, a blank 32′ that is cylindrical, in particular in form of a—preferably short—cylinder, is provided.

[0096] In particular, the blank 32′ is machined from a planar blank (not shown), for example from a cut piece of sheet metal or similar material by cutting, in particular by mechanical cutting, laser or water jet cutting, sawing, milling or eroding, and/or subsequently is preferably (pre-)contoured and/or pre-contoured or contoured by machining, in particular by turning, milling and/or grinding. It is also possible, however, to produce the blank 32′ with a contouring. In an alternative embodiment, the blank 32′ can be brought into the shape of a cylinder by swaging, forging or rolling.

[0097] The same applies without limitation for the embodiment of the method according to the invention that is represented in FIGS. 8A to 8L. This embodiment differs from that shown in FIGS. 6A to 6L in that also in step a) instead of a blank 32 that is flat, planar or largely planar or of similar shape, preferably essentially circular or disk-shaped, or circular or disk-shaped, a blank 32′ that is cylindrical, in particular in form of a—preferably short—cylinder, is provided.

[0098] The methods according to the invention that are shown in FIGS. 7A to 7J and in FIGS. 8A to 8L have the additional benefit that the cylinder shape and/or the length of the cylinder allow to individually determine the amount of material of the edge 40′ which is or should be eventually available depending on the required wall thickness and/or the mutual overlapping area with an adjacent container structure 20, 20′, 20″ and/or the at least one other cylinder element 46, 46′.

[0099] Apart from that, the embodiments of the methods according to the invention shown in FIGS. 5A to 5J and FIGS. 7A to 7J are identical to those shown in FIGS. 6A to 6L and FIGS. 8A to 8L.

[0100] The invention is not limited to the illustrated embodiments. Without being shown in detail, the container 10 can also have more than just one chamber 16 or two chambers 16, 16′ with a bulkhead 18 separating the two chambers 16, 16′. Therefore, also containers 10 with three and/or more chambers 16, 16′ and bulkheads 18 in any respective number are conceivable within the framework of the invention. Without being shown in detail, alternatively it is of course also possible, for example, to provide a splitting of the edge 40, 40′ and/or of the material of the blank 32 protruding at the edge already before the convex spin forming and/or turning. Furthermore, it is conceivable that the support structure or spin chuck 34 and/or the other support structure or spin chuck 38 has/have corresponding negative contours to generate the reinforcements 30, for example in the form of (stiffening) ribs, ribs, reinforcing ribs, stringers and/or isogrid or orthogrid structures, and/or other—also (partially) smooth-walled—structures in the cylinder section(s) 26, 28, on the outside and/or inside, preferably on the inside, during flow turning or flow pressing and/or spinning.
