Resumo

The implementation of an Urban Air Mobility (UAM) environment poses a significant challenge, involving various factors such as the introduction of a disruptive aircraft concept: eVTOLs (Electric Vertical Takeoff and Landing aircraft). In a scenario marked by traffic congestion in major urban centers, the idea of envisioning a sustainable, reliable, and financially advantageous mode of transportation becomes highly appealing. Nevertheless, to achieve this objective, it is crucial to understand the characteristics and limitations of the innovative transportation system to develop a cost model that aims for a sustainable profit margin. Consequently, this study seeks to create a comparative model that considers the cost advantages of both fixed-wing and rotary-wing aircraft in a hybrid approach, taking into consideration the energy requirements of an electric propulsion system. Additionally, this study proposes a thorough analysis and comparison of the ownership costs associated with three different eVTOL engineering configurations, with the aim of highlighting the advantages of each. Subsequently, a cost operating model for these aircraft is proposed, accounting for the hybrid behavior they exhibit. To provide information and comparisons, a drone and a helicopter model are employed to establish benchmarks for the vertical takeoff and landing mission components, while a fixed-wing aircraft from the regional aviation group is utilized to guide the model during the cruising phase. Based on these findings, it becomes feasible to draw conclusions regarding the potential financial benefits and identify areas where efforts should be concentrated to establish UAM at an economically viable level.
