Electromechanical Flight Control Actuation Update

The new rare-earth sammarium-cobalt magnets are revolutionizing electromechanical actuation design to the extent that power-by-wire can be a legitimate follow-on to fly-by-wire. These new magnets coupled with innovative design techniques which feature direct interface with fly-by-wire are creating electromechanical actuator designs that are highly competitive to hydraulic actuators in terms of weight, space, and performance. A major promise of these new electromechanical actuators is to permit unification of total secondary power systems under a single medium, electrical.
