Abstract:
A container for storing compressed gas includes a plurality of aligned glass capillaries extending into a tubesheet. Each of the capillaries has an open end flush with a front face of the tubesheet. An end cap having a gas outlet connectable to a compressed gas valve or conduit is fitted to the tubesheet in gas-tight fashion to form a high pressure space defined by inner surfaces of the capillaries, the front face of the tubesheet, and inner surfaces of the end cap.
Abstract:
A cryogenic propellant depot and sunshield are provided for operation in earth orbit to fuel or refuel other space vehicles. The sunshield is deployed to effectively mitigate solar radiation emanating from the earth and the sun thereby providing a long term storage solution for cryogenic fluids prone to boil-off. The depot has supporting subsystems to include station keeping equipment and communication equipment so that the depot can be independently controlled. Inflatable booms are used to deploy the sunshield in a desired pattern around the depot.
Abstract:
The present invention relates to a vessel for a compressed gaseous fuel. The vessel has a non-cylindrical shape and is provided with a bulk head within the vessel. The vessel is surrounded by a composite comprising a fibre reinforcement that is wound around the vessel. The vessel comprises a liner with a shape that is substantially the same as the desired vessel shape. The liner is provided with at least one recess that extends around the liner and divides the liner in sections connected to each other by a passage. The fibre reinforcement is continuously wound around the liner in different directions to ensure sufficient vessel strength and the recess is filled with fibres so that the fibres in the recess constitute the bulk head. The invention further relates to a method for producing the claimed vessel.
Abstract:
Among other things, a gas storage system includes a group of capsules and an activation element coupled to the group. The group of capsules are formed within a substrate and contain gas stored at a relatively high pressure compared to atmospheric pressure. The activation element is configured to deliver energy in an amount sufficient to cause at least one of the capsules to release stored gas.
Abstract:
Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source between the bladder and a device that includes the mating connector. The device may be a portable electronics device such as a laptop computer. Refillable hydrogen fuel source storage devices and systems are also described. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision.
Abstract:
A cryogenic propellant storage tank system and method are disclosed that thermally couple LO2 and LCH4 tanks together by using either a single tank compartmentalized by a common tank wall or two separate tanks that are coupled together with one or more thermal couplers having high thermal conductivity. Cryogenic cooling equipment may be located only in the LO2 tank while the LCH4 is cooled by the LO2 tank interface. Embodiments of the invention may employ both LO2 and LCH4 liquid acquisition devices (LADs) for low-gravity use. In further embodiments, only the LO2 LADs may be integrated with thermal cooling equipment.
Abstract:
Embodiments of vessels include personnel access provisions having welded or otherwise permanent connections that substantially reduce the potential for leakage into or out of the vessels by way of the personnel access provisions.
Abstract:
A process prevents a reduction in the strength of the joint between the liner components, and assures high productivity without impairment. The peripheral walls (6, 7) of the liner component (4) and each of the second liner components (5) are brought into contact with each other, a probe (22) of friction agitation joining tool (20) is placed into the two liner components across the contact portions thereof, and the probe (22) in rotation is thereafter moved relative to the two liner components (4, 5). Assuming that the number of revolutions of the probe (22) is R rpm and that the speed of joining of the two liner components (4, 5) is V mm/min, R/V is in the range of 2≦R/V≦12.

Abstract:
A pressure vessel arranging and integrating a plurality of vessel structures each including a cylindrical liner opened at both ends and a fiber reinforced resin layer covering the outer periphery of the peripheral wall of the liner. Dome-shaped communicating members bulging outward are fixed across both respective ends of the liners of the vessel structures, thereby making the interiors of these liners communicate with each other and closing the open ends of these liners. This pressure vessel can be installed with no wasted space, and also allows an increase in capacity.
Abstract:
The invention regards a tank for storing of fluid at very low temperature, as LNG, which tank comprises external plates, forming roof, side walls and floor, and an internal cell structure with fluid communication between all the cells in the cell structure at floor level of the tank. At least a part of the external plate comprises a layered structure and where the internal cell structure is formed as self equilibrating support and or anchoring for the external plates. The invention also regards a cell structure for use in a tank for storing fluid.
