An aircraft fuselage section of an aircraft extending along a longitudinal direction, wherein the aircraft fuselage section comprises:
- a first fuel storage tank and a second fuel storage tank arranged in a caudal tandem configuration, such that the second fuel storage tank is arranged consecutively with respect to the first fuel storage tank according to the longitudinal direction;
- wherein the first fuel storage tank comprises a first end portion oriented towards the second fuel storage tank, and the second fuel storage tank comprises a second end portion oriented towards the first fuel storage tank, such that a fuselage subsection is defined between the first end portion of the first fuel storage tank and the second end portion of the second fuel storage tank;
- wherein the aircraft fuselage section further comprises:
- a first casing arranged at the first end portion of the first fuel storage tank, the first casing being configured to house at least two conduits in fluid communication with an interior of the first fuel storage tank, such that the at least two conduits pass through the first casing, and
- a second casing arranged at the second end portion of the second fuel storage tank, the second casing being configured to house at least two conduits in fluid communication with an interior of the second fuel storage tank, such that the at least two conduits pass through the second casing;
- and wherein:
- the first casing extends from the first end portion of the first fuel storage tank into the fuselage subsection,
- the second casing extends from the second end portion of the second fuel storage tank into the fuselage subsection,
- the first casing and the second casing are configured to keep a closed volume confined within the first casing and the second casing under vacuum conditions, and
- the first casing spaced apart from the second casing according to a separation direction contained in a plane perpendicular to the longitudinal direction.
