Definitions

  • the invention relates to a tank for separating a liquid from a gaseous phase and for storing the liquid separated from the gaseous phase for use in experiments in space under conditions of weightlessness, with a feed line through which a liquid, a gas or a mixture from both can be introduced into the tank, and with an outlet from the pure gas escapes.
  • the liquid introduced into such a tank which is generally referred to as a separator tank, is stored therein for the duration of a space experiment, the fuel metering being carried into this separator tank via an upstream tank.
  • a propellant usually an inert gas such as helium (He) or nitrogen (N 2 ), which is pressed under pressure into the upstream tank and in this way the liquid, the gas or a liquid Gas mixture through a piping system in the separator tank promotes.
  • a corresponding amount of gas is removed from the separator tank, these gases usually being discharged from the experiment module into the vacuum prevailing in orbit.
  • phase separators for the separation of a liquid from a gaseous phase has become known, wherein in this known device, a phase separator for operating states with low acceleration is used and the separation is carried out using superconducting magnets.
  • the describes US 48 48 987 A a phase separator in which pumps and a series of valves are provided.
  • a propeller which sets a liquid-gas mixture in rotation and in which a membrane of polyethylene or nylon, the liquid, in this case water, separated.
  • This latter known system is intended for use with fuel cells and is not suitable for separating cryogenic liquids.
  • US 44 35 196 A and the US 46 17 031 A Known devices are limited to use in the gravitational field of the earth.
  • a described arrangement is a porous bed structure in the form of a known Katalysatorbettn for generating gas from a liquid fuel, for example Hydrazine, provided.
  • a liquid / gas separator is described, in which a titanium mesh is arranged, which is intended to retain gas bubbles by the action of capillary forces and surface tension.
  • a diphasic cold gas propulsion system for a spacecraft as well as a suitable spherical tank known.
  • a lower portion of the tank has a porous structure which binds the two-phase fuel in its liquid phase by capillary forces. Via an outlet tube, the fuel can escape in gaseous phase.
  • a heating device is arranged, which heats the tank and thus also the fuel. As a result of the heating, the fuel in the upper region of the tank is in the superheated gaseous state and can escape through the outlet tube.
  • the invention has the object of providing such a tank in such a way that in a simple manner safe phase separation for both cryogenic and non-cryogenic propellants and liquids at accelerations, such as occur during a space experiment in a sounding rocket, is guaranteed and that the Once stored in this tank, liquid can not leave the tank through either the inlet or the outlet.
  • the invention solves this problem in that body are arranged in the tank of a spongy material in the form of a metal foam whose total pore volume is chosen to be greater than the volume of the liquid to be absorbed.
  • the formation of the tank according to the invention ensures that the liquid is absorbed capillary by the spongy material in the form of a metal foam and stored in this stable for the duration of the experiment.
  • the volume of the metal foam which is aluminum foam in a preferred embodiment of the tank according to the invention, is chosen larger than the volume of the total liquid to be absorbed according to the invention.
  • the liquid-gas mixture starting from the inlet opening, meandering guided by the acting as a separator tank tank according to the invention and thereby the liquid is discharged capillary into the sponge-like material.
  • a metal mesh In front of the outlet from the separator tank is a metal mesh, which prevents any particles of the sponge-like material that are being detached from undesirably entering the outlet opening.
  • the liquid is stored in this way in the serving as a reservoir tank, which may initially expelled in this tank located propellant gas and is replaced by the liquid.
  • the tank is inventively designed such that the liquid is stored in this due to the capillary action of the metal foam.
  • Metal foams are therefore also suitable for the type of storage of cryogenic liquids provided according to the invention, since they have a very low structural mass, so that only a small amount of structural mass has to be cooled by the liquid. Furthermore, the high capillary pressure of the metal foam has a positive effect, so that liquids can be safely held in the metal foam even at high interference accelerations. The storage capacity is reached when the bodies of metal foam are completely saturated with liquid.
  • the volume of the metal foam is dimensioned such that the maximum amount of liquid is less than the pore volume of the metal foam.
  • the invention is particularly well-suited for such space-saving experiments under weightlessness which require the use of cryogenic liquids.
  • a storage or test tank 3 is connected via a feed line 2 to a compressed gas tank 1.
  • the test tank 3 can be emptied, so that either liquid or gas is discharged from the test tank 3.
  • the liquid or gas is discharged via line 4 into a separator tank 5.
  • This separator tank 5 stores the introduced liquid and, via a line 6 and further via degassing lines 7, discharges the gas escaping from the separator tank 5.
  • the structure of the separator tank 5 is particularly made Fig. 2 seen. It consists of in the case of this embodiment, annular plate elements or bodies 8 made of a metal foam, wherein the metal foam in this case is aluminum. These bodies 8 are inserted into the separator tank 5, wherein the separator tank 5 is bounded by an upper 9 and a lower lid 10 and is enclosed by a cylindrical shell 11.
  • the outer shape of the separator tank 5 shown here serves only as an example and can generally be adapted to the geometric conditions in a spacecraft.
  • the in Fig. 3 illustrated in detail inlet region into the separator tank 5 consists of a supply line 12, which opens into a circumferential injection channel 13.
  • This injection channel 13 is connected in the direction of the cylindrical shell 11 through a gap 14 with the interior of the separator tank 5.
  • a sleeve 16 is arranged, which is located in front of the pore openings 17 in the body 8 made of metal foam.
  • a further sleeve 18 made of a metal fabric, which is connected to an outlet 19 of the separator tank 5 is connected.
  • This sleeve of metal fabric 18 has the function of a screen or filter cartridge, ie, any contamination downstream, not shown in the figures devices or valves by particles are avoided by this sleeve 18.
  • Fig. 5 the flow path 20 through the separator tank 5 is shown.
  • the separation of the liquid from the gas is carried out by the capillary penetration of the liquid 21 into the sponge-like body 8 made of metal foam, as in Fig. 6 is shown.
  • the liquid-impregnated region of the metal foam is in Fig. 6 indicated by a dashed area 22.
  • the lines 23 indicate the momentary boundary between the liquid (dashed area 22) and the gas (in the rest of the metal foam).
  • the flow direction of the liquid-gas mixture is indicated by the arrow 24.
  • the cross section 20 between the individual metal foam bodies is adjusted accordingly. This cross section 20 between the individual metal foam bodies is getting wider in the flow direction 24. Accordingly, the recesses 15 in the sponge-like bodies 8 made of metal foam in the direction of the center of the Separatortanks 5 are always deeper, as can be seen from Figures 4 and 5.
  • the separator tank described above is suitable for both cryogenic and non-cryogenic liquids.
  • the representation according to Fig. 7 Finally shows an arrangement in which the separator tank 5 is used for cryogenic liquids. It is important that the temperature of the separator tank 5 is close to the liquid temperature. Therefore, in this case, the separator tank 5 is disposed together with the test container 3 inside a cryostat 25 in which heaters 26 are further provided. Finally, a gas supply device 27 and a gas sampling device 28 are shown schematically in this figure.
  • the separator tank 5 is initially filled with liquid, the temperature of which can be adjusted by presetting a pressure which is predetermined according to the saturation curve. The liquid then evaporates over time, so that the separator tank 5 assumes cryogenic temperatures at the beginning of the actual use. When the liquid has completely evaporated, the separator can be used. To accelerate the evaporation process, a heating device 26 is additionally provided, which serves to prepare the separator tank 5.
