Conceptual design methodology for eVTOL

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. Subsequently, a comprehensive analysis of the various eVTOL configurations currently being designed by various international companies will be carried out. Starting from some design specifications, including range, payload capacity and regulatory requirements set by government agencies such as EASA, statistical and analytical models will be used to carry out the aircraft sizing. In more detail, the thesis will explore the main design factors – mass estimation, propulsion requirements and battery configuration – in order to obtain preliminary sizing results that will be useful for optimising the performance of the aircraft for urban air mobility. This research will endeavour to consider the technological challenges and requirements of the transition to eVTOL technology, with a particular focus on the various systems that contribute to the functionality of these aircraft. This will provide a foundation for future design advances that prioritise safety, efficiency and reduced environmental impact.
