摘要:
A gas cylinder (14) having an aluminium shell (22), a composite wrap (20), and a plastic coating (24). The aluminium shell (22) has an outer side (26) and an inner side (28) defining a storage space (30). The composite wrap (20) is disposed about the aluminium shell (22). The plastic coating (24) is disposed on the cylinder inner side (28).
摘要:
A propellant or oxidizer tank system and process for densifying liquid propellant (104) or liquid oxidizer comprises a propellant tank (100) with a combined manifold (102), a combined manifold line (108), a pressurizing gas line (112), and a vent line (114). The combined manifold (102) is located in the tank (100). The combined manifold line (108) functionally connects the combined manifold (102) to a chilling system (18). The pressurizing gas line (112) and the vent line (114) are also functionally connected to the combined manifold line (108). The tank (100) may be disposed in a vehicle. The manifold (102) is disposed proximate the top of the tank (100). The chilling system (18) is a heat exchanger/filling system. The process for filling the tank (100) comprises the steps of charging the tank (100), venting gases (106) in the tank (100), densifying the liquid (104), and pressurizing the tank (100). The tank (100) is charged with the liquid (104) such that the orifices (120) in the combined manifold (102) are submerged. The gases (106) in the tank (100) are vented through the combined manifold (102) and out of the tank (100). The venting step is arrested prior to the submerging of the combined manifold orifices (120). The liquid (104) in the tank (100) is densified by directing a recirculation stream of the liquid propellant (104) or oxidizer from the tank (100) through the combined manifold (102), out of the tank (100), cooling and directing the recirculation stream into the tank (100). The tank (100) is pressurized by directing a pressurizing gas stream into the combined manifold (102) and into the tank (100) after the densifying step.

Le dispositif de stockage comporte: une enceinte (10) contenant un liquide et un gaz de pressurisation et un dispositif de sortie de liquide (20) comprenant une structure (21) constituée par des éléments rigides qui définissent une surface intérieure ajourée formant barrière de gaz et délimitent un passage central de sortie (16) et qui délimitent des espaces dont la largeur croît en fonction de la distance au passage central depuis une valeur minimale choisie pour ladite barrière de gaz, jusqu'à une valeur maximale choisie pour empêcher le liquide contenu dans la structure d'être expulsé dans l'enceinte tant que l'accélération ne dépasse pas un seuil donné, la structure constituant un réservoir-tampon duquel le liquide peut être extrait par le passage central sous l'effet du gaz lors de chaque phase d'utilisation et qui est réalimenté en liquide contenu dans l'enceinte au moyen d'un dispositif d'alimentation (15) qui aboutit à une entrée (29) de liquide dans la structure.
摘要:
To provide a propellant tank such as a fuel tank 6 and an oxidant tank 7 for a spacecraft, the propellant tank discharging propellant such as liquid hydrogen and liquid oxygen accumulated therein toward a rocket engine by pressurizing an inside thereof by operating gas. The propellant tank includes a tank body 11 that accumulates therein the propellant in a liquid state, and a holding container 12 that is provided inside the tank body 11 and disposed with a predetermined gap from an inner wall of the tank body 11, so that the propellant in a liquid state can be held therein, when the inside of the tank body 11 is in a microgravity state or a zero-gravity state.
摘要:
A set (10) for dispensing liquefied gas from a vessel (100) comprises a supporting structure (1), a pump (2) and a conditioning system (4). The supporting structure is designed for maintaining both the pump and the conditioning system inside the vessel when the set is in operation condition for dispensing a flow of liquefied gas. The set allows easy handling, simple fitting to the vessel and easy removal from the vessel because a main part of said set can be handled as a one-block element.
