Electromechanical Actuation Displaces Hydraulics On New Designs
Airframers designing new aircraft keep removing hydraulic circuits and replacing them with electromechanical actuators, because a hydraulic system carries pumps, reservoirs, pipework, fluid mass and a maintenance burden that a motor and a screw jack simply do not. Each substitution adds motors to the shipset. The transition began with secondary flight controls and spoilers and has moved steadily toward primary surfaces as reliability data accumulated. It is unglamorous, it requires no new aircraft category, and it produces most of the revenue this industry currently earns. Nobody writes press releases about spoiler actuators.
