Abstract:
A hydrogen fuelled aircraft includes a fuselage, a wing, at least one hydrogen fuelled gas turbine engine, at least one hydrogen fuel tank configured to store liquid or supercritical hydrogen and a hydrogen fuel line configured to delivery hydrogen fuel from the fuel tank to the engine. The gas turbine engine and the hydrogen fuel tank are each installed externally on the wing, and the hydrogen fuel line does not pass through the fuselage.
Abstract:
The invention relates to a storage bag for temporarily accommodating the liquefied petroleum gas, to a liquefied petroleum gas storage, to a fuel supply system, and to an assembly for buffering a liquefied petroleum gas (LPG) in a liquefied petroleum gas storage. The storage bag is arranged for temporarily accommodating the liquefied petroleum gas, having a fuel collection volume and a supply unit for allowing liquefied petroleum gas from the storage to enter into the fuel collection volume. The assembly can comprise a fuel pump having a pump housing and an inlet connected to the fuel collection volume. According to the invention a fuel pump and storage bag connection is arranged to allow feeding of the assembly the one after the other through an opening of the liquefied petroleum gas storage. According to the invention the storage bag comprises a jet pump.
Abstract:
This invention is directed to pressure vessels in which the strength necessary to withstand the pressure exerted by a contained fluid under intended operating pressures is provided by a dry filamentous over-wrap.
Abstract:
The present invention relates to a fire resistant pressure vessel in which the inclusion of fire resistance does add appreciably to the overall weight of the vessel over a similar vessel that is not fire resistant.
Abstract:
A toroidal pressure vessel having extremely high pressure resistance has laminated latitudinal reinforcing fiber layers to improve a strength in a latitudinal direction of the pressure vessel. Moreover, putting reinforcing fibers constituting those laminated latitudinal reinforcing fiber layers in continuity enables further improvement of strength in the latitudinal direction of the pressure vessel, for example compared with a case where the reinforcing fibers are divided for each layer.
Abstract:
In a propellant tank, which especially stores cryogenic propellants, for example a fuel or an oxidizer for a spacecraft, and which operates with a driving gas to drive or convey the propellant, the propellant is separated from the driving gas in a propellant extraction apparatus using sieves with hydrostatic forces and capillary forces. The extraction apparatus includes a refillable reservoir, which is mounted near the tank floor outside of the tank shell, and which is connected via plural holes with the interior of the propellant tank. The extraction apparatus includes a double-walled housing that is thermally insulated. Capillary plates and struts are inserted in an L-shape into the reservoir. To substantially prevent the penetration of gas out of the propellant line, a cylinder-shaped pleated sieve is mounted at the end of the propellant line.
Abstract:
Improved process for evacuating the thermally insulating jacket of a dewar having an inner wall and an outer wall, with the inner space between said walls completely or partially filled with an insulating material, containing also a moisture sorbing material and a getter material, in which said moisture sorbing material is a chemical drying agent.
Abstract:
A vessel for containing a fluid is provided. A composite wall encloses the fluid chamber and is connected, at at least one location, to a shaft-like body which traverses the fluid chamber and extends through the composite wall. A sealing ring is further provided to which the composite wall is connected at the connection location(s) and is slidable around the shaft-like body, subject to being limited in at least one axial direction by a stop means.
Abstract:
A vessel for containing a fluid under pressure comprises essentially flat parallel surfaces connected by hemispherical edge closures. Internal tension members are connected between the parallel surfaces to distribute the pressure of the fluid in the vessel. The shape of the vessel can be generally square, triangular, toroidal, or other variation to conform to an available space. The skin of the vessel, the hemispheric edge closures, and the internal tension members are typically fabricated from a high strength lightweight material, such as titanium.
