An apparatus for fixing a pressure vessel to an object includes: a frame member configured to be fixed to the object; a first locking part configured to lock one axial end of the pressure vessel to the frame member; and a second locking part configured to lock another axial end of the pressure vessel to the frame member.

The disclosure relates to a tank for storing volatile gas under pressure and a structure comprising the tank. The tank has a wall formed of a filament wound carbon fibre reinforced polymer (CFRP). The CFRP may have a graphene nanomaterial filler dispersed in the polymer adhesive matrix. The structure includes a frame for bearing static and dynamic forces from internal and external loads, the frame including the tank, the tank being an active load bearing structural element configured as a stressed member in the frame such that, in the structure in use, the tank bears static and dynamic forces from internal and external loads. One or more of: the filament winding pattern of the carbon fibre, the wall thickness, the wall shape, or the material properties of the polymer matrix including the dispersed graphene; is configured such that the tank has mechanical properties required by the design of the structure.

An aircraft comprising a structure, a tank housed in the fuselage, and fastening means which comprise a front fastening system, a rear fastening system and a lateral fastening system. The front system comprises a front plate, two lateral connecting rods and a central connecting rod that are fastened between the front plate and the tank. The rear system comprises a rear plate and a rear connecting rod fastened between the rear plate and the tank. The lateral system comprises a lateral connecting rod fastened between the structure and the tank, wherein one of the connection points is behind the other connection point.

A storage frame for cylinders of pressurized fluid, including a primary structure and at least one storage box including at least one cylinder of pressurized fluid extending along a longitudinal axis between two ends, having at least one first retaining member configured to collaborate fixedly with one end of the at least one cylinder and blocking the rotation of the cylinder, and at least one second retaining member configured to collaborate with the other end of the cylinder.

A tank has a generally prismatic shape, and is capable of containing a pressurized gas. The tank comprises a composite shell, which has fibrous reinforcements and a matrix extending continuously over the six faces of the prism and delimits a sealed internal cavity comprising a plurality of open cells. The tank comprises continuous fibrous reinforcements extending into and bonded to the composite shell and further extending through the internal cavity between two opposite faces of the tank. The tank is advantageously integrated into the floor of a vehicle, in particular to the structure of an aircraft.

The invention relates to a container/container support assembly, notably for a medical gas cylinder, comprising a gas container (11) comprising a protective cap (3) comprising a peripheral wall (3), and a container support (20) able and designed to accept and bear said gas container (11). The protective cap (3) of the gas container (11) comprises a fixing element (10) projecting from the surface of the peripheral wall (3), and said container support (20) comprises an attachment system (24) for fixing said container support (20) to a bearing structure (30), and a housing (22) able and designed to accept said fixing element (10) borne by the protective cap (3) of the gas container (11) so as to secure said gas container (11) to said container support (20) when said fixing element (10) is positioned in said housing (22) of the container support (20).

A cold-box system includes a bulk gas tank, and a plurality of cold-box compartments operationally associated with the bulk gas tank. A cold-box apparatus includes a plurality of cold-box compartments operationally associated with a bulk gas tank. In one embodiment the cold-box compartments may be spaced apart from the tank aboard a waterborne platform.
