Cryogenic tank comprising at least one anti-sloshing structure, aircraft comprising at least one tank of this kind

A cryogenic tank comprising:

• at least one enclosure containing a liquid phase and having a first orthogonal direction, a second orthogonal direction, and a third orthogonal direction, the third orthogonal direction being vertical;
• at least one anti-sloshing structure positioned inside the at least one enclosure, the at least one anti-sloshing structure comprising a first plurality of walls and a second plurality of walls arranged so as to compartmentalize the at least one enclosure;
• at least one connection system connecting the at least one anti-sloshing structure and the at least one enclosure;
• and
• at least one piece of equipment dedicated to a gaseous phase,
• wherein the anti-sloshing structure comprises at least one partition which, together with the at least one enclosure, defines an upper region in which the at least one piece of equipment is positioned,
• the at least one partition comprising a central portion substantially perpendicular to the third orthogonal direction, and a first wing and a second wing each located a side of the central portion and form an angle of between 5° and 45° with a plane passing through the central portion.
