Driven by global growth in demand for high-speed mobility, the need for environmentally-responsible solutions in aircraft systems has been recognized as a priority in the development of future aircraft configurations. Future aircraft concepts must be developed to reduce energy usage, community noise, net operating costs, and emissions relative to current systems. The emergence of electrified propulsion architectures has enabled a new dimension of aircraft design that promotes a synergistic integration of traditional subsystems. This seminar will provide an overview of recent innovations in electrified aircraft concepts, including efficiency improvements facilitated by strategic aero-propulsive coupling, methods for integration of distributed propulsion in aircraft attitude control mixing, and the holistic design of fully-electric commercial aircraft concepts.
