1. A nacelle system having a translating structure, comprising:
a fixed structure;
a thrust reverser including a translating sleeve, a blocker door, and a first hydraulic system, the blocker door configured to be activated by the first hydraulic system, the translating sleeve configured to translate from a stowed position to a deployed position relative to the fixed structure;
a sleeve actuator connected between the fixed structure and the translating sleeve, the sleeve actuator configured to translate the translating sleeve between the stowed position and the deployed position, wherein the first hydraulic system operates in response to the translation of the translating sleeve; and
a variable area fan nozzle including a translating nozzle configured to translate relative to the translating sleeve and in response to a second hydraulic system, wherein each of the first hydraulic system and the second hydraulic system include:
a primary hydraulic actuator, the primary hydraulic actuator having a primary hydraulic fluid end and a primary gaseous fluid end;
a secondary hydraulic actuator having a secondary hydraulic fluid end and a secondary gaseous fluid end;
a hydraulic supply line configured to fluidly couple the primary hydraulic fluid end of the primary hydraulic actuator to the secondary hydraulic fluid end of the secondary hydraulic actuator,
wherein the hydraulic supply line is configured to fluidly couple a first reservoir to the primary hydraulic fluid end of the primary hydraulic actuator and to the secondary hydraulic fluid end of the secondary hydraulic actuator.
