Passively actuated variable area nozzle for an aircraft propulsion system

Abstract

An aircraft system is provided that includes a propulsion system structure and a variable area nozzle. The propulsion system structure includes a duct, and is adapted to move between a first position and a second position. The variable area nozzle is fluidly coupled with the duct. The variable area nozzle is adapted to move between a first configuration and a second configuration. An exit area of the variable area nozzle has a first value when the variable area nozzle is in the first configuration. The exit area of the variable area nozzle has a second value when the variable area nozzle is in the second configuration. Movement of the variable area nozzle between the first configuration and the second configuration is mechanically linked with movement of the propulsion system structure between the first position and the second position.
