Thee Evolution of High Lift Actuation: From Hydraulics to Electrification

For decades, high lift devices were primaryly actuated by hyhydraulic systems. Hydraulics offer high power density and proven reliability, but t they come with inherent drafts: hevy piping runs, potential for fluid stres, slow responsie times, andd high contriance burdens. Pneumatic systems were also use d on some designs, but they sur from compressibility and lowefficiency.
