Over the past few decades, aviation has accounted for a significant percentage of global CO2 emissions, contributing to the climate change our planet is experiencing today. To face this problem, a potential new form of aviation, known as Urban Air Mobility (UAM), has been introduced in recent years. One of the main technologies that UAM refers to is the concept of Electric Vertical Takeoff and Landing (eVTOL). This new generation of VTOL aircraft aims to fly more economically and environmentally than ever by combining the convenience of vertical/short takeoff and landing like a helicopter with the efficient aerodynamic flight of an airplane. The eVTOL ONAerospace design will have as its main objective to fulfil all the functions previously presented during rescue and/or medical assistance missions, dividing the study and design of each part of the aircraft among the different members that are part of the ONAerospace group. This final degree project will consist of carrying out an in-depth study for the implementation of a V-tail, also known as a ¿butterfly¿, with the aim of fulfilling the main functions of any aircraft stabilizer. The possibility of implementing control surfaces that are capable of providing control in engine failure conditions (OEI) will also be studied. The tail design will follow the footsteps of numerous tail design books. The process will first consist in the design of a conventional tail with a horizontal and vertical stabilizer and finally, a conversion to an unconventional V-tail will be carried out trying to maintain the same aerodynamic performance as the previously designed conventional tail. To achieve the aforementioned, an analytical investigation will be carried out to determine the geometry of the tail as well as for the selection of the most convenient aerodynamic airfoil by means of Computational Fluid Mechanics (CFD). The study will be carried out by comparing various airfoils typically used for tail design and, from there, selecting the one that best suits the requirements to be met. Finally, it has been possible to present a valid and viable solution capable of meeting all the requirements established by ONAerospace. On the other hand, it has been possible to size the control surfaces of the V-tail, which are capable of responding to a situation of engine failure without having to make huge deflections, which would result in the generation of great aerodynamic resistance.
