The HP-SMART-EMA project developed and tested an innovative concept of extremely light, reliable and smart electrical actuator for control systems of turbine engines that will be capable of interfacing and connecting to the engine / turbine control unit in a plug-and-play manner. This innovative concept of smart electrical actuators was based on a multi-disciplinary approach that considered mechanisms, control electronic, control software and power supply in an integrated way, as will be shown in the following subchapters. The main topics developed in this proposal were related to the temperature levels and environmental conditions (combustion gas, oxidation) that are the normal aero engine working conditions, and result to be highly demanding for any electromechanical system working under these conditions.
