    摘要： The invention relates to a liner segment (10) for a frame bay (34) of a fuel tank structure, comprising a liner segment base body (12), wherein the liner segment base body (12) is adapted to float on fuel in the fuel tank structure, at least one liner segment side wall (14), wherein the at least one liner segment side wall extends from the liner segment base body (12), a multitude of drainage holes (16), wherein the multitude of drainage holes (16) is arranged in the liner segment base body (12), and wherein the multitude of drainage holes (16) is adapted to provide a bidirectional fluid connection from an upper side (18) of the liner segment (10) to a bottom side (20) of the liner segment (10) facing the fuel tank structure, at least one valve (22), arranged in a cut out (30) of the liner segment (10), wherein the at least one valve (22) is adapted to provide an unidirectional fluid connection from the bottom side (20) of the liner segment (10) to the upper side (18) of the liner segment (10), such that the unidirectional fluid connection is blocked in the opposite direction, such that a remaining portion of fuel within the fuel tank structure is reduced by securing the fuel flow from underneath a liner segment of an adjacent frame bay to the liner segment (10) that is needed to extend safe fuel pump operation in the fuel tank structure.

    摘要： Example systems and methods for using multi-directional baffles in cryogenic fuel tanks are provided. An example cryogenic fuel tank (700) comprises an inner surface (702) defining an interior of the cryogenic fuel tank (700) to hold a fuel and a plurality of baffles (804) including a first baffle (500), the first baffle including a first member (504) extending along a first plane and a second member (506) extending along a second plane, the first plane different from the second plane, the second member (506) connected to the first member (504), the plurality of baffles (804) connected to the inner surface (702).

    摘要： In general terms, the invention provides a cryogenic tank (100) for storing cryogenic fluids. The cryogenic tank is typically configured to be mounted on a vehicle for supplying cryogenic fuel to a propulsion system of the vehicle. The cryogenic tank comprises an inner vessel (10) for containing cryogenic fluids and an outer vessel (30) surrounding the inner vessel to define a vacuum insulating volume therebetween. The outer vessel is configured to transmit static and/or dynamic loads, while the inner vessel is partially or completely isolated from such loads.
