The demand to optimize aircraft performance, decrease operating and maintenance costs, increase dispatch reliability, and reduce gas emissions - have underscored the aircraft industry's renewed push toward the concept of all electric aircraft. Specifically, the AEA concept provides for the utilization of electric power for all propulsive and non-propulsive systems. Traditionally the primary aircraft propulsive power requirements are derived from gas powered turbine jet engines and APU’s with non-propulsive systems driven by a combination of different secondary power sources such as hydraulic, pneumatic, mechanical and electrical. Recent technological innovations and advances in the field of electric aircraft propulsion, power electronics, fault-tolerant architecture, electro-hydrostatic actuators, flight control systems, high density electric motors, energy dense battery evolution, power generation and conversion systems have ushered in the era of all-electric aircraft. This trend is accelerating, as aircraft OEMs collaborate with their suppliers to design new systems that hybridize traditional propulsion systems and implement new electrical-intensive architectures, with the ultimate milestone of an all-electric-aircraft. Adoption of the AEA concept is seen as critical enabler for the aircraft industry to unlock significant improvements in terms of aircraft weight, fuel consumption, total life cycle costs, maintainability and aircraft reliability.
