Abstract

A variable area nozzle for an aircraft engine includes a nozzle inner structure, a nozzle outer structure, an actuation system and a flowpath. The nozzle inner structure includes a nozzle wall and a nozzle sleeve. The nozzle wall includes a plurality of slots arranged circumferentially about the axis. Each of the slots projects radially through the nozzle wall. The nozzle sleeve axially overlaps and circumscribes the nozzle wall. The actuation system includes a carriage and an actuator. The carriage 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 where the nozzle sleeve is attached to the carriage at an outer end of the carriage. The actuator is disposed radially within the inner nozzle wall and is coupled to the hub. The actuation system moves the nozzle sleeve axially along the nozzle wall.
