ABSTRACT:
A fuel tank for a spacecraft stores a liquid fuel and a pressurized propellant gas that drives the fuel out of the tank through a fuel extraction arrangement including a reservoir or collection container and a tank outlet. The collection container bounds a fuel reservoir space that communicates with the interior space of the tank, and fuel flow channels connect the reservoir space to an outlet pipe. A side or area of the collection container opposite the fuel flow channels is provided with one or more grooves. These structures produce a capillary pumping effect and use the surface tension to separate the fuel from the propellant gas.
