The aim of this thesis is to present a design methodology for a category of new aircraft: eVTOLs (electric vertical take-off and landing). This thesis will analyse the potential of sustainable urban mobility solutions through advanced air mobility (AAM). In light of the intensification of urban congestion and the environmental problems caused by increasing air pollution, eVTOL vehicles appear to offer a promising solution to replace or complement urban transport. In the first part of this thesis, eVTOL technology will be contextualised within the historical trajectory of personal air vehicles, with a particular focus on its potential to reduce carbon emissions in urban transport.
