The invention includes a joint assembly for connecting first and second longitudinal edges of portions of an acoustic barrel or panel having an open cell core, a perforated inner skin, and an outer skin. The joint assembly includes at least one strip covering a plurality of openings in walls of cells along the first and second longitudinal edges. The strip is separate from the inner and outer skins. A plate includes a first portion connected to the outer skin proximate to the first longitudinal edge, and a second portion connected to the outer skin proxi...


What is claimed is: 1. A method of maximizing the available acoustic area of an engine nacelle inner barrel having an acoustic cellular core, a perforated inner skin, an outer skin, and at least one longitudinal seam extending between opposing edges of the acoustic cellular core, the method comprising:(a) providing an acoustic cellular core having a first cut edge and a second cut edge;(b) covering the first cut edge of the cellular core such that substantially all of the cells along the first cut edge remain substantially unobstructed;(c) covering the s...
