초록

An acoustic liner jet engine inlet barrel is formed from a perforated permeable skin, a honeycomb core, and a solid facesheet, each of which is formed in a one-piece configuration such that at most only a narrow single fore-to-aft splice, or no splice at all, is present in the finished product. The acoustic modal content remains unaffected, thus preserving a high degree of liner effectiveness, increasing the total active acoustic area of the barrel while decreasing its weight, and increasing its durability.

청구항

An engine inlet acoustic barrel having a one-piece monocoque structure, said barrel being substantially cylindrical in shape and having a forward end, an aft end, and an air passage surface in an interior of the cylindrically-shaped barrel, comprising, from the air passage surface outward: a one-piece inner facesheet; a continuous one-piece core structure surrounding said inner facesheet; and a continuous one-piece non-porous back facesheet surrounding said core structure, wherein said one-piece inner facesheet and said one-piece core structure have no s...
