A liner assembly for a fan case includes a noise attenuation layer covered by a face sheet. The face sheet includes openings to the underlying noise attenuation layer. The face sheet and noise attenuation layer include acoustically transparent joints. The noise attenuation layer includes a first side joined to a second side at a seam by an adhesive strip. The adhesive strip bonds the first side to the second side without filling any chambers. The face sheet includes a joint filled with an adhesive providing the desired uninterrupted surface within the fa...
What is claimed is: 1. A liner assembly for a fan case comprising: a noise attenuation layer; and a face sheet over said noise attenuation layer, said face sheet including a first plurality of openings and a joint, wherein said joint comprises a first seam comprising overlapped sides of said face sheet and an adhesive disposed over said overlapping sides, said joint including a second plurality of openings extending through said adhesive and each of said overlapped sides of said face sheet for communicating sound energy through said joint to said noise ...
