Environmental assessment of hybrid-electric propulsion in conceptual aircraft design

摘要: Abstract The aeronautic industry is facing increasing pressure to design more efficient and sustainable aircraft mitigate their impact on the environment. These solutions are mainly focused on: aerodynamics, structures/materials, propulsion operations. This paper focuses potential of electric systems in different segments for reducing environmental life cycle. With a twofold contribution linking areas, this study presents methodological proposal assessment system change consequential Life Cycle Assessment perspective. methodology uses data from both modified conceptual adapted hybrid-electric battery study. Results show not only impacts required each segment cycle perspective, but also what contexts may be considered best alternative environmentally when compared with fuel systems. For that, sensitivity analysis illustrate results electricity mix cell capacities. main overall process charging system, therefore source generation crucial sustainability aircraft.
