Novel actuation systems are driver of product innovation in aerospace industry. In aircraft industry EHA technology has been recently introduced illustrating the stream of innovation directed on improving performance, reliability as well as economy. On the far side there is the radical concept of a morphing wing which offers optimizing the aerodynamics of an aircraft considerably by shape control. Rotor Active Control utilizing piezo actuation has been proofed to be very successful for vibration and noise reduction in helicopter flight test inspiring confidence in smart structure technology.
