This thesis presents the conceptual design process of a Powered-Lift electric Vertical Take-off and Landing (eVTOL) Aircraft with a Fuel Cell–Battery Hybrid System for Urban Air Mobility (UAM) applications. The primary objective is to evaluate the feasibility and benefits of such aircraft as a promising solution to the growing traffic congestion in ever more urbanized cities, with the additional advantages of reducing air pollution from traditional road transport systems. The study focuses on the potential of hybrid powerplant configurations that combine the high power density of batteries for power-demanding flight phases such as take-off, with the high energy density of fuel cells for energy-demanding flight phases such as climb and cruise.
