LLTVAS LAT

The lower central stage of the Ariane 6 launcher is powered by the Vulcain 2.1 engine. The LL-TVAS (Low Liquid Thrust Vector Actuation System) is the actuation system that allows gimballing the engine nozzle according to the Guidance and Navigation Control requirements. Due to the specificity of the Vulcain engine, a hydraulic actuation system with direct drive servo-valve has been selected.
This direct drive servovalve is to be driven by a LAT (Limited Angle Torque) motor with flooded rotor and accurate electrical and mechanical characteristics necessary for the open loop control of the valve (no position sensor on the spool).
Beside the need for Ariane 6 and other future potential launcher developments, this type of motor for a direct drive valve is also used by SABCA for aeronautic applications.
