Abstract

By producing a centrifugal force, by means of an existing tank insert, on liquids in weightless conditions, a deliberate movement of the particles is achieved and the extraction from the tank is thus improved even in the event of disturbing accelerations occurring.

Description

Unter Schwerelosigkeit verhalten sich Flüssigkeiten in geschlossenen Behältnissen anders als unter irdischen Bedingungen. Ohne zusätzliche Hilfsmittel ist eine Aussage über eine mögliche Flüssigkeitsverteilung im Tank nur schwer möglich. Dies um so mehr, je größer die von außen auf den Tank eingeleiteten Störbeschleunigungen sind. Die bisher verwendeten Tanks nutzen die Oberflächenspannung von Flüssigkeiten aus und sind relativ anfällig für größere Störbeschleunigungen.Liquids behave under weightlessness in closed containers differently than under earthly ones Conditions. Without additional aids is a statement difficult about a possible liquid distribution in the tank possible. The bigger the outside from the outside, the more so Tank accelerations are initiated. The so far Tanks used use the surface tension of Liquids spill out and are relatively susceptible to larger ones Accelerations of interference.

Durch die Rotation eines Einsatzes im Tank (Fig. 1) wird eine gerichtete Bewegung der Flüssigkeit erzeugt. Die auftretende Zentrifugalbeschleunigung läßt die Flüssigkeitsteilchen in einen um den Tank laufenden Wulst wandern, von wo die Flüssigkeit abgesogen werden kann.By rotating an insert in the tank ( Fig. 1), a directional movement of the liquid is generated. The centrifugal acceleration that occurs causes the liquid particles to migrate into a bead running around the tank, from where the liquid can be drawn off.

Die Tankeinsätze können blatt- oder scheibenförmig sein, sowie Kombinationen davon (Fig. 1, Fig. 2).The tank inserts can be leaf or disk-shaped, as well as combinations thereof ( Fig. 1, Fig. 2).

Claims (3)

Das Tankkonzept soll die gezielte Entnahme bzw. Betankung von Behältern unter Schwerelosigkeit verbessern.The tank concept is designed for targeted removal or refueling improve containers under zero gravity. Die Erfindung ist dadurch gekennzeichnet, daß eine gerichtete Bewegung der Tankflüssigkeit durch die Rotation eines Tankeinsatzes (Quirl) erzeugt wird. Die auftretende Zentrifugalbeschleunigung läßt die Flüssigkeitsteilchen gezielt zur Tankaußenwand und damit bei kugelförmigen Behältern in den Bereich des größten Durchmessers wandern.The invention is characterized in that a directed movement of the tank liquid is generated by the rotation of a tank insert (whorl). The centrifugal acceleration that occurs causes the liquid particles to migrate specifically to the outer wall of the tank and thus to the largest diameter in the case of spherical containers. Der Ein- und Auslaßbereich des Tanks ist dadurch gekenn­ zeichnet, daß sich ein umlaufender, ringförmiger Wulst am größten Tankdurchmesser befindet, in dem sich die Flüssigkeit sammelt.The inlet and outlet area of the tank is known records that there is a circumferential, annular bead is at the largest tank diameter in which the Liquid collects.
