DRIVE
September 10, 2025
An apparatus for an aircraft propulsion system includes a variable area nozzle apparatus (66). The variable area nozzle apparatus (66) includes a plurality of panels (76), a plurality of inter-panel members (78) and an actuation system (74). The panels (76) are arranged circumferentially about an axial centerline (32). The panels (76) include a first panel (76A) and a second panel (76B). The inter-panel members (78) are arranged circumferentially about the axial centerline (32). The inter-panel members (78) include a first inter-panel member (78) between and connected to the first panel (76A) and the second panel (76B). The first inter-panel member (78) is configured from or otherwise includes an elastomeric material. The actuation system (74) is configured to move the panels (76) and the inter-panel members (78) between a restricted flow arrangement and an unrestricted flow arrangement. The actuation system (74) includes a first linkage (110) and a second linkage (110). The first linkage (110) is coupled to the first panel (76A). The second linkage (110) is coupled to the second panel (76B).
