Actuators – Space

JASC hydraulic and fueldraulic actuators control rocket engine nozzle and aerodynamic fin position on commercial spaceflight rockets.

Thrust Vector Control Actuator

This actuator was designed to control the thrust vector angle on the SpaceX Falcon 9 first- and second-stage engines. It is designed for high vibration and shock loads, and has excellent frequency response characteristics. It also was designed for short-term immersion in salt water, as evidenced by the protective cover on the electro-fueldraulic servo-valve (EFSV) and hard anodic coatings. Redundancy is accomplished via dual-coils in the EFSV first-stage torque motor.
