Influence of Novel Airframe Technologies on the Feasibility of Fully-Electric Regional Aviation

The feasibility of regional electric aviation to reduce environmental impact highly depends on technological advancements energy storage techniques, available battery density, and high-power motor technologies. However, novel airframe technologies also strongly affect the a aircraft. In this paper, influence was investigated. Three game-changing were applied all-electric aircraft: active flow control, load alleviation, materials structure concepts. Initial conceptual design mission analysis aircraft performed using framework SUAVE, sensitivity most important characteristics performance studied. Obtained results compared against reference ATR-72 Results showed that an with might be designed maximum take-off weight increase 50% starting from pack density 700 Wh/kg. overall emission level is reduced by 81% ATR-72. On other hand, do not contribute reduction in Direct Operating Costs (DOC) Wh/kg if without An DOC ranges 43% 30% depending which creates significant market obstacle for such type airplanes. addition, shows high levels consumption concerns its efficiency. Finally, sensitivities each technology assessed.
