Abstract

Procédé amélioré dépollution d'un réservoir d'aéronef L’invention concerne un procédé de dépollution d'un réservoir d'aéronef comprenant une vessie (12) souple logée dans une chambre (14) ménagée dans une structure dudit aéronef, et un matériau absorbant (21) prévue entre ladite vessie (12) et ladite chambre (14), la chambre (14) comprend au moins une prise de drainage (22) et est équipée d’une interface de connexion fluidique (10) à la vessie (12), caractérisé en ce qu’il consiste à dépolluer en carburant ladite chambre (14) en mettant en œuvre les étapes suivantes : - depuis l’interface de connexion fluidique (10), injecter de l’air chauffé dans la vessie (12); - depuis la prise de drainage (22), purger l’air contenu dans ladite chambre (14) jusqu’à expansion de la vessie ’12) et compression du matériau absorbant (21) par la vessie (12) contre les parois de ladite chambre (14). Figure de l’abrégé : Fig.2Improved method for decontaminating an aircraft tank The invention relates to a method for decontaminating an aircraft tank comprising a flexible bladder (12) housed in a chamber (14) formed in a structure of said aircraft, and an absorbent material (21) provided between said bladder (12) and said chamber (14), the chamber (14) comprising at least one drain port (22) and is equipped with a fluidic connection interface (10) to the bladder (12), characterized in that it consists of decontaminating said chamber (14) with fuel by implementing the following steps: - from the fluidic connection interface (10), injecting heated air into the bladder (12); - from the drain port (22), purging the air contained in said chamber (14) until expansion of the bladder (12) and compression of the absorbent material (21) by the bladder (12) against the walls of said chamber (14). Figure from the summary: Fig. 2
