An aircraft engine ( 10 ) includes a pivot-door type thrust reverser ( 22 ) located at an aft portion of a nacelle ( 16 ). The thrust reverser ( 22 ) includes a monolithic fan duct barrel ( 24 ) with an annular wall ( 50 ) that includes a forward section ( 46 ), a door section ( 54 ), and an aft section ( 48 ). The wall ( 50 ) has a honeycomb-sandwich type structure with an interior face sheet ( 60 ) and a backing sheet ( 62 ) radially separated by a first cellular core ( 66 ). An outer sheet ( 64 ) associated with the aft section ( 48 ) of the wall ( 50 ) is radially separated from the backing sheet ( 62 ) by a second cellular core ( 68 ). A plurality of pivoting doors ( 26,28 ) mate with a plurality of door openings ( 56,58 ) in the door section ( 54 ) of the annular wall ( 50 ). Each door ( 26,28 ) has honeycomb-sandwich type structure similar to that of the annular wall ( 50 ), wherein each door ( 26,28 ) has an interior face sheet ( 74 ) separated from a backing sheet ( 76 ) by a first cellular core ( 80 ), and an outer sheet ( 78 ) separated from the backing sheet ( 76 ) by a second cellular core ( 82 ).
