Which system uses hydraulically operated actuators to control nozzle movement?

• A. Anti-Icing System.
• B. Variable Exhaust Nozzle (VEN).
• C. Fan Variable Geometry (FVG).
• D. Compressor Variable Geometry (CVG).

Answer: (B)

The system that uses hydraulically operated actuators to move the nozzle is the Variable Exhaust Nozzle. It changes the exhaust area by shifting nozzle petals, allowing the engine to optimize thrust and efficiency across different flight conditions and back-pressure scenarios. The other options serve different purposes: anti-icing focuses on preventing ice buildup rather than moving the nozzle, while fan and compressor variable geometry adjust internal flow paths and compression components, not the nozzle exit itself.
