초록

A sound absorbing structure 38, 52 for a gas turbine engine 10 is disclosed. The sound absorbing structure 52 includes a wall element 54 and a casing 34 of the engine or nacelle 12. The casing is spaced from the wall element leaving a cavity 62 therebetween which is compartmentalized by partitions 64, 66. In one embodiment the partitions are attached to either the wall element or the casing element. In another embodiment the partitions are all attached to the wall element and spaced from the casing element or are all attached to the casing element and sp...
