Electrohydrostatic Actuator
電気油圧アクチュエータを単純に説明すると、電気で油圧ポンプを作動させて、エンジンからの油圧供給を不要としたもの。エアバスＡ３８０の昇降舵とエルロンをコントロールします。ですから、エンジンからの油圧ではなく独立したアクチュエータです。方向舵とスポイラーは、Electrical Backup Hydraulic Actuator 電気パックアップ油圧アクチュエータで動かします。通常はエンジンからの油圧で作動しますが、バックアップモードになると電気ポンプで作動させます。はい、かっこいい！

To put it simply, these are things that use electricity to operate their hydraulic pumps, which makes it unnecessary for the engine to provide hydraulics itself. They control the Airbus A380's landing gear and ailerons. Thus hydraulic pressure does not come from the engine but from an independent actuator. The rudder and spoiler are driven by an Electrical Backup Hydraulic Actuator. Normally hydraulic pressure from the engine would drive these, but when in backup mode, they move with electronic pressure pumps. Hey, isn't that cool!
