The unavoidable element in the development of flight control systems (to date) has been in hydraulic actuators. This has been the case primarily because of their proven reliability and the lack of alternative technologies. However, the technology to build electromechanically actuated primary flight control systems is now available, which may mark the end of the hydraulic actuation systems - an important step for the development of the future 'all-electric' aircraft. Design and Development of Multi-Lane Smart Electromechanical Actuators describes design concepts in electromechanical actuators by considering an actuator that has the capability to drive the aerodynamic and inertial loads of an aileron control surface similar to that of the Sea Harrier. It provides the necessary theoretical background to design smart multi-lane electromechanical actuation systems, and provides a general methodology that engineers (electrical, mechanical, mechatronic, aerospace or chemical) will find useful.
