A system for storing fuel includes a support structure supporting at least one fuel tank a predetermined distance above ground. The fuel tank includes an inner tank configured to contain a gaseous fuel, an intermediate tank encompassing the inner tank and defining a first annular space therebetween, and an outer tank encompassing the intermediate tank an defining a second annular space therebetween. The first annular space is filled with a shock-absorbing resin for absorbing structural stresses, while the second annular space is filled with an insulating material providing for fire and ballistic resistance. The intermediate tank is connected to the support structure and to at least one adjacent fuel tank, and prevents the transfer of load to the inner tank.

Methods and manufactures disclosed herein generally relate to a cannular composite (ITC) structure composed of multiple layers of scaling, reinforcement, sensing, protection, and interspatial injected materials.

A pressure vessel includes a body defined by a cross-sectional shape along a plane transverse to a centerline. The cross-sectional shape includes an inner surface defining an interior void and a wall extending from the inner surface to an outer surface defining an exterior of the body. The inner surface includes an arcuate region and a gabled region. The gabled region forms a curved interior peak opposite a center of the arcuate region. The arcuate region and the gabled region together define a teardrop shape. The wall includes a curved segment along the arcuate region having a curved segment minimum thickness at a location opposite the interior peak, an apex aligned with the interior peak and having an apex thickness, and thickened regions adjacent intersections between gabled region and the arcuate region and having greater radial thickness than the curved segment minimum thickness.

Disclosed are a processing apparatus, a corrugated plate, and a storage container. The processing apparatus includes a pair of slide plates, a pair of press plates, a shaping block, and a driving mechanism. The driving mechanism includes a slide plate driving portion linked to a shaping block driving portion, allowing the slide plate driving portion drives the pair of slide plates to approach each other at a first predetermined speed, the shaping block driving portion moves the shaping block downward at a second predetermined speed, and the first and second predetermined speed are specifically correlated with respect to a predetermined forming profile of an intersection portion. The processing apparatus of the present disclosure causes running speeds of various portions that move in different directions to extrude a blank plate to be specifically associated, so that the formation process is particularly applicable to a corrugated plate having the predetermined corrugated shape.

An organic composite gas storage tank 300 comprises a hollow central portion 306 which is substantially cylindrical and formed integrally with first and second end portions 302, 304, and which defines a longitudinal tank axis 301. The first end portion comprises a hollow truncated conical region which meets the hollow central portion at a first end thereof. The hollow central portion comprises first and second hollow truncated conical portions 306A, 306B, the external radius of a given hollow truncated conical portion decreasing in a direction towards a corresponding end portion. The tank comprises an organic composite fibre winding extending between first and second positions along the length of the tank which coincide with the first and second hollow truncated conical portions of the hollow central portion respectively, biassing these portions together and increasing the axial strength of the central portion.

This invention describes a novel design and construction method for a Collapsible Cryogenic Storage Vessel that can be used for storing cryogenic liquids. The vessel provides the ability to be packed for transport in a compact state and erected at the point of use. The vessel can be used multiple times. The vessel's volume can also be adjusted during use to minimize or eliminate head space in the vessel.

In order to enlarge a tank volume of a hydrogen powered aircraft, an aircraft tank for storing cryogenic H.sub.2 is configured as a non-circular dorsal tank. The aircraft tank may be configured as a conformal fuel tank fitted to an outer contour of an aircraft fuselage. Further, an aircraft is provided with such an aircraft tank.

A method and apparatus for transporting a liquid gas container is described herein. The liquid gas container is transported at an increased internal pressure. Transporting the liquid gas container at an increased internal pressure distributes the downward load of the liquid gas container, such that the downward load of the liquid gas container is distributed more evenly or so that a greater amount of the downward load is felt in the center of the liquid gas container compared to the outer portion of the liquid gas container. This enables transport without cracking of a base support slab during transit when the support slab is only able to be supported from the center due to narrow road conditions.

An illustrative example container includes a plurality of internal support members having a surface contour that at least approximates a minimum surface. The plurality of internal support members collectively provide structural support for carrying loads on the container. The plurality of internal support members collectively establish a plurality of cavities for at least temporarily containing fluid. An outer shell is connected with at least some of the internal support members. The outer shell includes a plurality of curved surfaces. The outer shell encloses the cavities.
