CA 2692620

An aircraft (1) comprises a cabin (2) in which at least part of the space is demarcated by trim panels and the cabin is provided with a system (6) for the active control of ambient noise. Each trim panel (2) is either an active panel (4), comprising actuators (8)powered by the active noise control system (6), or a passive panel (5) without such actuators. In addition, the trim panels of the cabin (2) of the one type, either active or passive, are mechanically interchangeable with a panel of the other type, either passive or active, respectively. Power supply wiring (3) for active panels is installed in the aircraft (1), this wiring being capable of powering all active panels (4) which could be installed, whether said active panels are actually installed or whether interchangeable passive panels (5) are installed. Finally, a power supply system (61) for the active panels is installed in the aircraft (1) and connected to the power supply wiring (3) of the active panels.

Un aéronef (1) comporte une cabine (2) dont au moins une partie de l'espace est délimitée par des panneaux d'habillage et la cabine est pourvue d'un système (6) de contrôle actif du bruit ambiant. Chaque panneau d'habillage (2) est soit un panneau actif (4), comportant des actionneurs (8) alimentés par le système (6) de contrôle actif du bruit, soit un panneau passif (5) ne comportant pas de tels actionneurs. En outre les panneaux d'habillage de la cabine (2) d'un type, actif ou passif, sont mécaniquement inter-changeables avec un panneau de l'autre type, respectivement passif ou actif. Un câblage (3) d'alimentation de panneaux actifs est installé dans l'aéronef (1), câblage en mesure d'alimenter l'ensemble des panneaux actifs (4) pouvant être installés, que les dits panneaux actifs soient effectivement installés ou que des panneaux passifs (5) interchangeables soient installés. Enfin un système (61) d'alimentation des panneaux actifs est installé dans l'aéronef (1) et raccordé au câblage (3) d'alimentation des panneaux actifs.
