Monolithic structure for mounting aircraft engine

摘要

Assembly includes an integral monolithic structure (12) for mounting an engine to an aircraft (13). The monolithic structure (12) includes a nacelle portion (14) and a support structure. The nacelle portion (14) includes an inlet region (22) and a fan case region (24) defining an annular wall (26) about an axial channel (28). A ring member (30) disposed in the axial channel (28) is connected through a plurality of radial elements (34) to the annular wall (26). The support structure portion (16) includes a forward section (40) integral with the nacelle portion (14) and an aft section (44) including at least one aircraft mount region (48) for mounting the monolithic structure (12) to an aircraft (13). The forward section (40) includes an inlet stiffening region (42) radially outward of the annular wall (26). When mounted on the aircraft (13), the nacelle portion (14) and the support structure portion (16) cooperate to form a first load path (50) operable to transmit an applied nacelle maneuvering force directly to the aircraft (13) instead of through the engine core.
