Abstract

La présente invention concerne un procédé de fabrication d’une paroi (20) d’un fuselage d’un aéronef et une telle paroi (20). Ladite paroi (20) est destinée à fermer un compartiment moteur et comporte un circuit de ventilation dudit compartiment moteur. Ladite paroi (20) est formée par au moins une structure alvéolaire (23) comportant une multitude de rangées (25) d’alvéoles ainsi que deux peaux (21,22) agencées de part et d’autre de ladite au moins une structure alvéolaire (23). Un réseau de canaux (27) est créé dans l’épaisseur de ladite paroi (20) par une suppression partielle de rangées (25) d’alvéoles de ladite au moins une structure alvéolaire (23) et/ou par des espaces entre des structures alvéolaires (23). Un orifice d’entrée (28) communiquant avec un canal (27) est agencé dans une peau (21) extérieure et plusieurs orifices de sortie (29) communiquant respectivement avec des canaux (27) distincts sont agencés dans une peau (22) intérieure.
