This is one of the most demanding fields for servo valve technology.
Flight Control Surfaces (Actuators): Servo valves control the hydraulic actuators that move ailerons, rudders, elevators, flaps, and spoilers. They translate the pilot's commands or fly-by-wire signals into precise mechanical movements to control aircraft attitude and stability.
Thrust Vector Control (TVC): In military fighter jets and spacecraft (e.g., rockets, missiles), servo valves adjust the direction of the engine nozzle, precisely controlling the direction of thrust for superior maneuverability and stability.
Landing Gear Systems: They manage the extension, retraction, and steering of landing gear, ensuring smooth and reliable operation under high loads.
Engine Control: Servo valves are used in fuel metering systems and variable geometry components (like inlet guide vanes) of jet engines to optimize performance and efficiency
