Abstract: A tank comprising an outer enclosure, an inner enclosure positioned in the outer enclosure, and at least one duct passing through first and second walls connected respectively to the outer and inner enclosures. The first and/or second walls comprises at least one deformable zone interposed between, on the one hand, an attachment zone which connects the wall and the outer or inner enclosure and, on the other hand, a connection zone which comprises a connection connecting the wall and the duct. Also an aircraft with such a tank.

Abstract: A tank comprising an outer enclosure, an inner enclosure positioned in the outer enclosure and at least one tubular interface passing through the outer and inner enclosures and linked to the outer enclosure by a first link and to the inner enclosure by a second link, the tubular interface comprising at least two sections placed end-to-end and at least one joining system linking the sections pairwise, a first section being linked to the outer enclosure by the first link, a second section being linked to the inner enclosure by the second link.

Abstract: A tank comprising an outer enclosure, an inner enclosure positioned in the outer enclosure, and at least one duct passing through first and second walls respectively fastened to the outer and inner enclosures, the tank comprising, for each duct, first and second rigid connections connecting the duct and respectively the first and second walls. Each duct comprises an intermediate segment, situated between the first and second walls, which has a curved axis such that the intermediate segment has an excess length between the first and second walls.
