摘要:
A demisable fuel supply system for a satellite includes a pressurized aluminum alloy tank (12) with an aluminum alloy propellant management device therein. The propellant management device (PMD) can have any capillary action surface tension fluid transport features known in the art. Selected inner surfaces of the tank (12) and the PMD are covered with a plasma powder sprayed titanium based coating to guarantee propellant wettability and corrosion resistance of the fuel supply system.

In einem Tank zur Lagerung kryogener Flüssigkeiten oder lagerfähiger Flüssigkeiten für einen Einsatz in Weltraumexperimenten unter den Bedingungen der Schwerelosigkeit sind zur sicheren Trennung von Gas- und Flüssigkeitsphase Strukturen aus einem schwammartigen Material, insbesondere aus einem Metallschaum, angeordnet, deren Gesamtporenvolumen größer gewählt ist als das Volumen der aufzunehmenden Flüssigkeit. Die Strukturen sind als ineinander liegend angeordnete ringförmige Platten ausgebildet, die im Inneren der zylindrisch ausgebildeten Tanks angeordnet sind. Im Zentrum des Tanks ist eine Entnahmevorrichtung angeordnet, die sich vor den Porenöffnungen des Metallschaums befindet. Für Weltraumexperimente unter Schwerelosigkeit, die den Einsatz kryogener Flüssigkeiten erfordern, kann der Tank zusammen mit einem vorgeschalteten Vorratstank in einem Kryostaten angeordnet werden, der mit einer Heizvorrichtung versehen ist.
摘要:
The invention relates to a device for expelling/containing a predetermined liquid, said device being capable of being built into a liquid tank that is to operate at low or zero gravity, and including a unitary three-dimensional so-called sponge structure (32) comprising a set of substantially wire-like elements (70) that extend between a peripheral area of the sponge and an area for expelling/containing liquid, wherein said wire-like elements are substantially oriented in the direction of flow of the fluid within the device, said wire-like elements being connected together by crosspieces and are arranged such that the capillary gradient is positive or zero in the direction of flow of the fluid from said peripheral area to said area for expelling/containing liquid.

The aim of the invention is to create a protective device for a pressure container for storing a pressurised gas, which device has a low mass and can be produced cost-effectively. Said aim is achieved in that the protective device comprises a protective case for encasing the pressure container and a safety case for encasing the protective case, wherein the safety case comprises a material that contracts when heated.
摘要:
A metallic liner for a composite reinforced high pressure gas cylinder is composed of a seamless metal tube contoured with a top dome and bottom dome. The liner is further composed of a seamless top metal end cap having a mating shape of the top dome and a seamless bottom metal end cap having a mating shape of the bottom dome. Alternatively, an extruded cup is shaped to a dome at the open end and one or two seamless metal end caps are used. In the method of manufacturing, the top and bottom ends of the metal tube are contoured, the end caps are produced, and one or two end caps are attached to the ends of the tube.
