Abstract:
To provide a propellant tank such as a fuel tank and an oxidant tank 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 that accumulates therein the propellant in a liquid state, and a holding container that is provided inside the tank body and disposed with a predetermined gap from an inner wall of the tank body, so that the propellant in a liquid state can be held therein, when the inside of the tank body is in a microgravity state or a zero-gravity state.
Abstract:
A tank trailer has a container formed from a tubular body and one or more polar bosses coupled to distal ends of the tubular body. The trailer includes a pumping system that has one or more pipes fluidly coupled to the interior of the container via an interface at one of the polar bosses. The tank trailer may have a base support and one or more circumferential support members coupling the base support to the composite container, or the support functionality of the base may be instead accomplished by the container. The one or more polar bosses may include an inner circular surface and an outer circular surface, wherein the outer circular surface has one or more flat portions that complement and engage one or more concave features of the substantially tubular body.
Abstract:
A cryogenic tank includes a membrane anchor mechanism which fixes a membrane provided on an inner wall surface side of a concrete wall via a heat insulating material to the concrete wall, a pressing par which is provided by the membrane anchor mechanism and presses the membrane from the inside of the cryogenic tank, and an interposition part which is interposed between the pressing part of the membrane anchor mechanism and the membrane, and includes a first abutment surface coming into surface-contact with the pressing part and a second abutment surface coming into surface-contact with the membrane.
Abstract:
A ring-wing floating platform is disclosed. The ring-wing floating platform includes a floating hull, a top of the floating hull being above a sea surface and its geometry at a water plane is centrally symmetric, a ring-wing surrounding a perimeter of a bottom of the floating hull with a horizontal projection of concentric annular geometries, a positioning system located at the bottom of the floating hull, and a topsides located above the floating hull and connected to the floating hull by deck legs or installed directly on the top of the floating hull. The axes of the ring-wing and the floating hull are collinear, and their bottoms are in a same horizontal plane. The ring-wing and the floating hull are connected together as a unitary structure by multiple connecting components with an annular gap in-between.
Abstract:
Embodiments of the present invention relate to compressed gas storage units, which in certain applications may be employed in conjunction with energy storage systems. Some embodiments may comprise one or more blow-molded polymer shells, formed for example from polyethylene terephthalate (PET) or ultra-high molecular weight polyethylene (UHMWPE). Embodiments of compressed gas storage units may be composite in nature, for example comprising carbon fiber filament(s) wound with a resin over a liner. A compressed gas storage unit may further include a heat exchanger element comprising a heat pipe or apparatus configured to introduce liquid directly into the storage unit for heat exchange with the compressed gas present therein.
Abstract:
An apparatus and method for supplying gaseous fuel from a tender car to an internal combustion engine on a locomotive comprising storing the gaseous fuel at a cryogenic temperature in a cryogenic storage tank on the tender car; pumping the gaseous fuel to a first pressure from the cryogenic storage tank; vaporizing the gaseous fuel at the first pressure; and conveying the vaporized gaseous fuel to the internal combustion engine; whereby a pressure of the vaporized gaseous fuel is within a range between 310 bar and 575 bar.
Abstract:
A filling station for filling a liquid cryogenic refrigerant from a supply tank to a receiver tank, the filling station comprising a flash tank between the supply tank and the receiver tank, adapted to de-pressurize the refrigerant that is transferred from the flash tank to the receiver tank, resulting in formation of a liquid cryogenic refrigerant phase and a vapour cryogenic refrigerant phase within the flash tank, and to phase separate the liquid and vapour cryogenic refrigerant phase, and a pump between the flash tank and the receiver tank, adapted for pumping the refrigerant out of the flash tank to the receiver tank, wherein the flash tank is equipped with a level control unit that is arranged to keep the level of the liquid cryogenic refrigerant phase within the flash tank at a predetermined minimum.
Abstract:
A tower structure with storing capacity for at least one medium is described. The tower structure comprising at least two substantially vertically oriented support structures for forming the tower structure, wherein at least one of the support structures comprises at least one constructive pressure vessel for forming the support structure. A method for building the tower structure also is disclosed. The pressure vessel based tower structure may have applications e.g. in wind mills and solar thermal towers.
Abstract:
The invention relates to an insulated chamber comprising at least one element that may operate at sub-ambient temperature, the space around the element(s) being filled with solid insulation and means for injecting a gas containing at least 95 mol-% nitrogen into the insulation, at least some of the gas-injection means opening at a position vertically above at least one element to insulate.
Abstract:
A compressed natural gas fueling system includes a frame arrangement with at least one tank disposed therein and an inlet that can receive a compressed natural gas fueling nozzle to fill the at least one tank. The fueling system can be attached with and supported by frame rails behind a cabin of a vehicle such that the inlet is positioned above the frame rails.
