摘要: A durable light weight, high temperature acoustic ceramic matrix composite (CMC) liner system. thin skin, also referred to as a facesheet (106), forms an outer layer of cell (104) in the CMC system, forming boundary with flow hot gases exhaust. backplate (108) opposite for cell. The truss structure is formed between and provides strength. When system replaces metal liner, thickness increased so that it about replaces. extends facesheet, channels or volumetric spaces. These spaces are filled air permeable materials (120) attenuate sound propagated by cooling range.
