Urban Air Mobility (UAM) is an emerging technology primarily used for passenger transport, driven by the growing awareness of the need to alleviate traffic congestion and reduce emissions. While UAM is expected to enter the market by 2030, with some aerial passenger transport projects already under development in 2023, there is limited information available regarding its potential application in cargo transport. Therefore, the purpose of this thesis is to propose a preliminary conceptual design for a UAM solution specifically tailored for last-mile delivery. This solution, similar to drones but with enhanced capabilities, aims to fulfill multiple orders by utilizing a main aerial platform equipped with small drones for parcel handling, enabling delivery to the end user via air transportation.
