The first high performance all electric airplane is not likely to include electro-mechanical actuation (EMA) for critical effector control. Efficient, improved hydraulics will likely fill the high duty cycle, high power needs until EMA matures for these applications. Electromotive direct drive valve mechanisms have been developed to replace secondary actuation stages as now used for fly-by-wire systems. This device couples the best features of existing EMA control and redundancy with existing high power hydraulic primary actuation. An ideal comprise actuation can be furnished with low risk for the now and near future advanced fly-by-wire systems. This paper addresses evaluation of a direct drive valve concept and its theoretical application in an advanced energy efficient Shuttle Orbiter flight control actuation system.
