1. A fastening system configured to fasten at least one tank configured to contain liquid hydrogen, the at least one tank having a center of gravity (CG), the fastening system configured to be integrated into a fuselage body of an aircraft (AC), the fastening system having a vertical plane of symmetry (P1), the fastening system linked to an orthogonal frame of reference (R) defined by an axis X configured to be parallel to a longitudinal axis (A1) of the fuselage body, a horizontal axis Y and a vertical axis Z,
wherein the fastening system comprises:
a longitudinal box extending parallel to the axis X, the longitudinal box having a longitudinal vertical median plane (P2) coincident with the vertical plane of symmetry (P1) of the fastening system, the longitudinal box having a horizontal median plane (P3) configured to comprise the center of gravity of the at least one tank, the longitudinal box comprising at least two longitudinal plates parallel to the vertical plane of symmetry (P1),
an upper structure fastened to an upper side of the longitudinal box,
a lower structure fastened to a lower side of the longitudinal box, and
at least two fastening frames distributed along the axis X, each of the at least two fastening frames comprising symmetrically, on either side of the vertical plane of symmetry (P1), two first fastening devices configured to connect the at least one tank to the upper structure by a sliding pivot connection of pivot axis (A2) parallel to the axis X, the pivot axis (A2) configured to be comprised in a plane (P2) perpendicular to the axis Z comprising the center of gravity (CG) of the tank;
the fastening system further comprising symmetrically, on either side of the vertical plane of symmetry (P1):
at least two second symmetrical fastening devices configured to connect a first fastening point of the at least one tank to the longitudinal box, the first fastening point configured to be comprised in the horizontal median plane (P3) of the longitudinal box, and
at least two third symmetrical fastening devices configured to connect a second fastening point of the at least one tank to the lower structure.
