MONOLITHIC THRUST REVERSER COMPONENTS

摘要

An aircraft engine nacelle (10) includes a pivot-door type thrust reverser. 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 interiorface 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).
