Abstract

An additively manufactured noise attenuation panel (3500) for a structure within an aircraft structure includes a plurality of unit cells, each including a central body interconnected via a plurality of tubes extending from the central body. The noise attenuation panel may include an increasing wall thickness in a desired direction. A layers (3551; 3552) of unit cells may be manufactured in a twisted orientation with respect to an immediately adjacent layer (3551; 3552) of unit cells. Layers of unit cells may be manufactured in a rounded or bent orientation with respect to a central axis (3594). The noise attenuation panel may further comprise a disk and a blended transition located at the interface between the disk and an interior surface of a unit cell.
