Abstract:
The present invention provides a method and a system for handling gaseous fuels using sub-tanks (3) as gas emitting entities within a fuel tank (1). In particular the invention provides a system comprising an exchanger unit (2) for filling filled sub-tanks (3) to, and removing emptied sub-tanks (3) from, the fuel tank (1). Thanks to the invention the filling and removal is fast, efficient and safe.
Abstract:
The invention comprehends a tank for storing fluid under pressure and a method for manufacturing the tank. The tank has an inner core of an open- celled foam that is characterized by open voids that are at least partially interconnected by passages and are surrounded by a fibrous or ligament structure/network (collectively, "ligaments"). Attached to the inner core is an outer skin.
Abstract:
The present disclosure is related to methods and apparatus that provide safe storage of volatile compounds or elements, utilizing storage configurations that take advantage of the diffusibility and release characteristics of cell-based materials, such as foam materials.
Abstract:
Le réservoir (10) pour système de propulsion à gaz froid diphasique d'engin spatial comprend une structure microporeuse (3) apte à assurer, dans une partie de réservoir (10) qui est opposée à un orifice d'évacuation de gaz (4) hors du réservoir (10), la rétention capillaire en phase liquide d'un fluide diphasique contenu dans le réservoir (10). Un dispositif de contrôle thermique du réservoir (10) comprend au moins un réchauffeur (2) associé à la partie du réservoir (10) contenant la phase gazeuse, ainsi qu'au moins une thermistance (5) dans cette partie, et au moins une autre thermistance (6) dans la partie de réservoir (6) contenant la structure microporeuse (3) et la phase liquide. La structure (1) mécanique du réservoir (10) est montée sur la structure de l'engin spatial par une interface (7) de montage rigide et une interface (8) de montage souple. Application à l'équipement notamment de satellites dans la gamme de quelques dizaines à quelques centaines de kilogrammes.
Abstract:
Apparatus controllably breaks hollow spheres stored in an enclosure. A first screen is disposed within the enclosure on a screen support. The screen has holes that are no larger in mesh size than the smallest hollow spheres. The screen support provides support to the first screen and has void areas to allow debris from broken spheres to pass through. An impeller is in contact with the first screen such that movement of the impeller across the first screen breaks the hollow spheres in contact with the first screen.
Abstract:
An apparatus and heating method for vaporizing liquid fuel within a tank (12) whereby the heat of vaporization is supplied from the ambient environment by utilizing a metallic foil tank insert (22) in heat conductive contact with the tank and the liquid fuel. This insert (22) is preferably a lattice of metal foil rolled to substantially occupy the tank volume and allowing fuel to circulate within. Vaporized fuel collects in the upper portion (16) of the tank (12) to exit through the valve (14).
Abstract:
A rigid structure propellant management device (PMD) liquid storage tank includes an outer shell and internal structures inside the outer shell that include a plurality of vertical columns each made up of a stack of individual storage cells. Each of the storage cells has solid vertical sidewalls and top and bottom capillary windows that allow vertical liquid transfer between adjacent cells in a vertical column. The top and bottom capillary windows in each of the storage cells have permeabilities that result in a selected direction of liquid flow in each column. A piping and valve system may be connected to the top capillary window of a top storage cell and to the bottom capillary window of a bottom storage cell of each vertical column, configured to allow controlled liquid transfer between adjacent vertical columns so that locations of empty cells in the tank as liquid is drawn from the tank achieves a selected column by column drainage sequence and controls a center of mass of the tank.
Abstract:
A fluid supply package is described, including a pressure-regulated fluid storage and dispensing vessel comprising a fluid dispensing flow path, and adsorbent disposed in the flow path or in fluid communication therewith to reversibly adsorb fluid from the flow path for pressure stabilization of fluid dispensed from the vessel. A corresponding method is disclosed, of stabilizing fluid pressure during dispensing of fluid through a fluid flow path in a fluid supply package, by contacting the fluid in the fluid flow path with an adsorbent on which the fluid is reversibly adsorbable during the dispensing of fluid. Such approach of using a pressure management adsorbent stabilizes fluid pressure during fluid dispensing, and combats pressure oscillations that may occur during initiation or subsequent performance of fluid dispensing.
Abstract:
A fuel gas storage tank is disclosed that can store fuel gas, such as natural gas or hydrogen, in a solid state. The fuel gas storage tank includes a shell having a tank interior, a fuel gas storage material housed within the tank interior, one or more fuel gas injecting tubes, and one or more fuel gas collecting tubes. Each of the fuel gas injecting tube(s) and the fuel gas collecting tube(s) is permeable to fuel gas and is disposed in the tank interior and surrounded by the fuel gas storage material. And, within the tank interior, the one or more fuel gas injecting tubes and the one or more fuel gas collecting tubes are not directly connected to one another.
Abstract:
Bei einem Behälter zum Transport und zur Lagerung insbesondere von kryogenen Flüssigkeiten, wie beispielsweise verflüssigtem Naturgas (LNG), mit einer Anordnung zur Dämpfung der Flüssigkeitsbewegung ist die Dämpfungsvorrichtung in Form eines Tragwerkes in den Behälter oder Tank eingebracht. Das Tragwerk besteht aus Stäben, Verbindungselementen, horizontalen, schrägen und vertikalen Blechen und ist in den Tank eingelegt, wobei seine äußere Form formschlüssig der Geometrie des Tanks angepaßt ist. Das Tragwerk ist über mit einer Schüttung befüllte Säcke im Inneren des Tanks angeordnet, und die Säcke sind durch Schrauben und Tellerscheiben miteinander verbunden. Über Bohrungen in den Rohren ist ein Füllen und Entleeren der Rohre des Tragwerks mit der zu transportierenden oder zu lagernden Flüssigkeit gegeben. Die horizontalen, schrägen und vertikalen Bleche sind an den Rohren und Verbindungselementen lösbar mittels Schrauben befestigt.
