Abstract

La présente invention concerne une nacelle pour turboréacteur d'aéronef, comportant une paroi (21) comportant un élément de support (35) d'un dispositif (37) annexe de la nacelle, ledit élément de support comportant : - une face (39) en regard d'une zone feu de la nacelle (3), et - un interstice (41) débouchant au niveau de ladite face (39) en regard de la zone feu. Selon l'invention, la nacelle est remarquable en ce que l'élément de support (35) comporte un dispositif d'obturation de l'interstice (41), non inflammable, monté dans ledit interstice (41) et comportant un ou plusieurs des éléments du groupe suivant : languette métallique, tube métallique, joint d'étanchéité vulcanisé. L'invention concerne également un procédé d'obturation d'un interstice (41) d'un élément de support (35) d'un dispositif (37) annexe d'une nacelle (3) pour turboréacteur d'aéronef.The present invention relates to a nacelle for an aircraft turbojet engine, comprising a wall (21) comprising a support element (35) of a device (37) annexed to the nacelle, said support element comprising: - a face (39) facing a fire zone of the nacelle (3), and - a gap (41) opening at said face (39) facing the fire zone. According to the invention, the nacelle is remarkable in that the support element (35) comprises a device for closing the gap (41), non-flammable, mounted in said gap (41) and comprising one or more of the parts of the following group: metal tab, metal tube, vulcanized gasket. The invention also relates to a method of sealing a gap (41) of a support element (35) of a device (37) annexed to a nacelle (3) for an aircraft turbojet.
