Abstract
An aircraft engine includes a rotating structure and a casing circumferentially surrounding the rotating structure. The aircraft engine further includes an acoustic panel for noise reduction circumferentially surrounding the rotating structure and disposed adjacent the casing. The acoustic panel comprises a plurality of acoustic panel members arranged adjacent to one another to form a substantially complete ring of the acoustic panel. A first acoustic panel member of the plurality of acoustic members is adjacent to a second acoustic panel member of the plurality of acoustic members. The first acoustic panel member is removably secured to the second acoustic panel member by a releasable fastening assembly.
