Aircraft equipped with at least one pressure-relief device including a mobile wall retained in a closed position

An aircraft comprising:

• at least one pressure-relief device including at least one fixed part and at least one mobile wall configured to occupy a closed position in which the at least one mobile wall blocks an opening and isolates interior and exterior zones on respective opposite sides of the mobile wall as well as an open position in which the at least one mobile wall at least partly frees the opening, the at least one mobile wall having an interior face oriented toward the interior zone and an exterior face oriented toward the exterior zone, the at least one pressure-relief device including at least one articulation connecting the mobile wall and the fixed part as well at least one retaining system configured to retain the mobile wall in the closed position as long as a pressure in the interior zone is lower than a given pressure value, the at least one mobile wall having at least one edge,
• wherein the at least one mobile wall is configured to be deformed so that the at least one mobile wall occupies a given deformed state when the pressure in the interior zone is at the given pressure value, and
• wherein the retaining system includes at least one slot through the at least one mobile wall opening at a level of the at least one edge of the at least one mobile wall, and, for each slot, a first retaining element fastened to the fixed part, the first retaining element and the first slot being configured so that:
• the first retaining element is accommodated in the at least one slot and retains the at least one mobile wall in the closed position as long as the at least one mobile wall is not in the given deformed state,
• the first retaining element is no longer accommodated the at least one slot and no longer retains the at least one mobile wall in the closed position as soon as the at least one mobile wall is in the given deformed state,
• wherein each retaining element comprises a screw that includes a body screwed into the fixed part and a milled head, and
• wherein each slot has an edge surface that is flared from an interior face to the exterior face of the mobile wall, the head having a section greater than a smallest section of said slot in which the retaining element is accommodated.
