Abstract

A variable area nozzle (20) for an aircraft engine includes a nozzle inner structure (24), a nozzle outer structure (22), an actuation system (26) and a flowpath (28) extending along an axis (32). The nozzle inner structure (24) includes a nozzle wall (44) and a nozzle sleeve (46). The nozzle wall (44) includes a plurality of slots (66) arranged circumferentially about the axis (32). Each of the slots (66) projects radially through the nozzle wall (44). The nozzle sleeve (46) axially overlaps and circumscribes the nozzle wall (44). The actuation system (26) includes a carriage (84) and an actuator (86). The carriage (84) includes a hub and a plurality of struts arranged circumferentially about and connected to the hub. Each of the struts projects radially through a respective slot (66) where the nozzle sleeve (46) is attached to the carriage (84) at an outer end of the carriage (84). The actuator (86) is disposed radially within the nozzle wall (44) and is coupled to the hub. The actuation system (26) moves the nozzle sleeve (46) axially along the nozzle wall (44).
