A Conceptual Design Methodology for e-VTOL Aircraft for Urban Air Mobility

Recent progress of electric systems has raised attention towards hybrid-electric and full-electric aircraft. Nevertheless, the current low battery energy density limits the application of these propulsive architectures to large transport aircraft. In the context of the general aviation category, ful...
