Patent number: 8381938Abstract: In a propellant tank, which especially stores cryogenic propellants, for example a fuel or an oxidizer for a spacecraft, and which operates with a driving gas to drive or convey the propellant, the propellant is separated from the driving gas in a propellant extraction apparatus using sieves with hydrostatic forces and capillary forces. The extraction apparatus includes a refillable reservoir, which is mounted near the tank floor outside of the tank shell, and which is connected via plural holes with the interior of the propellant tank. The extraction apparatus includes a double-walled housing that is thermally insulated. Capillary plates and struts are inserted in an L-shape into the reservoir. To substantially prevent the penetration of gas out of the propellant line, a cylinder-shaped pleated sieve is mounted at the end of the propellant line.Type: GrantFiled: September 13, 2006Date of Patent: February 26, 2013Assignee: Astrium GmbHInventors: Kei Philipp Behruzi, Mark Michaelis, Gaston Netter, Andreas Rittweger

Patent number: 8048211Abstract: A tank arrangement includes a tank for storing a liquid such as fuel or oxidizer for operation of a spacecraft and a pressurized driving gas for conveying the liquid out of the tank, and a gas supply and extraction device. The device includes a housing shell and plural outwardly expanding passage bodies providing openings that communicate the interior space of the tank to the inner reservoir space of the device. A baffle plate shields the outer opening of each passage body. Deflector plates are arranged in each passage body. Capillary plates extend longitudinally along the inner wall of the housing shell. By a capillary effect, the plates separate liquid from gas entering the device, so that the gas can be extracted while the liquid is stored in a reservoir of the device until it is drained back into the tank during an accelerated operation phase of the spacecraft.Type: GrantFiled: February 4, 2008Date of Patent: November 1, 2011Assignee: Astrium GmbHInventors: Kei Philipp Behruzi, Gaston Netter

Patent number: 8025721Abstract: A gas supply and extraction device is arranged preferably on a tank lid or a tank wall in a tank for storing a pressurized driving gas and a liquid such as fuel or oxidizer for operation of a spacecraft. A device housing defines an interior reservoir space. Upper trumpet-shaped passage bodies and a lower trumpet-shaped passage body communicate from the interior reservoir space into the interior space of the tank. By capillary effects, baffle plates, deflector plates, capillary plates, a separation chamber and other components separate liquid from gas entering the device, so that the gas can be extracted while the liquid is stored in the reservoir space of the device until it is drained back into the tank during an accelerated operation phase of the spacecraft.Type: GrantFiled: May 29, 2009Date of Patent: September 27, 2011Assignee: Astrium GmbHInventors: Kei Philipp Behruzi, Gaston Netter

Publication number: 20090134170Abstract: In a propellant tank, which especially serves for storing cryogenic propellants, for example of spacecraft, and which is operated with a driving gas serving as a conveying medium, the separation of the propellant from the driving gas occurs in a propellant extraction apparatus by means of sieves and with the use of hydrostatic forces and capillary forces. The extraction apparatus has the form of a refillable reservoir, which is mounted in the vicinity of the tank floor outside of the tank shell on the floor region of the propellant tank, and which is connected via a number of holes with the interior of the propellant tank. The extraction apparatus itself consists of a double-walled housing and is additionally thermally insulated. Capillary plates and additional struts are inserted in an L-shape into the reservoir. Furthermore, to substantially prevent the penetration of gas out of the propellant line, a cylinder-shaped pleated sieve is mounted at the end of the propellant line.Type: ApplicationFiled: September 13, 2006Publication date: May 28, 2009Inventors: Kei Philipp Behruzi, Mark Michaelis, Gaston Netter, Andreas Rittweger

Patent number: 7395832Abstract: 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.Type: GrantFiled: June 21, 2006Date of Patent: July 8, 2008Assignee: EADS Space Transportation GmbHInventors: Kei P. Behruzi, Mark Michaelis, Gaston Netter

Patent number: 4489745Abstract: The fuel tank as disclosed is provided particularly for storage of aggressive fuel as they are used for and in control jets, attitude positioning systems in satellite and space vehicles. The fuel tank is of a spherical configuration and partitioned by a conical insert to obtain two spaces of different volumes. The small end of the cone faces the fuel outlet, opposite the driving gas inlet, and is constructed as a narrow mesh sieve. The fuel outlet is surrounded by a collection chamber likewise closed off by a narrow mesh sieve. The smaller one of the two chambers includes fuel lines which end in the corner space where the conical partition is affixed to the spherical tank and are closed likewise by sieves. The invention uses the strong surface tension forces of the fuel wetting the mesh to create a barrier against the passage of driving gas into the fuel line and outlet of the tank.Type: GrantFiled: November 22, 1982Date of Patent: December 25, 1984Assignee: Erno Raumfahrttechnik GmbH/MBBInventors: Gaston Netter, Injas Widjaja
