Trabalho de Conclusão de Curso (Graduação)This work presents a multidisciplinary design optimization (MDO) for general aviation and hybrid-electricaircraftdesignintegratingboxesofaerodynamics,structures,flightmechanicsand performance. The methodologies used in each box are presented and, to increase the reliability on new designs, these tools were made to minimize or not use at all any historical data. The aircraft designed is present in the general aviation market and the requirements are specified according to its competitors, taking credit of a distributed propulsion system. Furthermore, the objective-functions are minimize fuel consumption and maximum takeoff weight. The results in terms of geometry, aerodynamic parameters and performance were compared to the aircraft competitors to evaluate the accuracy of the MDO. At least, the MDO generated a final project in order to highlight the commitment relationships of a hybrid-electric aircraft in matters of the objectuve-functions definded to this project.
