Thrust Vector Control Actuator

Thrust Vector Control Actuator (TVCA) by JASC

This actuator was designed to control the thrust vector angle on rocket engines. It is designed for high vibration and shock loads and has excellent frequency response characteristics. Redundancy is accomplished via dual-coils in the EFSV first-stage torque motor.

Embedded within the single-ended piston is a dual-element LVDT, which provides two independent channels of position feedback to the external controller. A single D38999 Series III connector on the EFSV housing communicates all signals to and from the controller. An optional electronic control unit (ECU) is available.
