Desenvolvimento e caracterização aerodinâmica de um veículo aéreo não tripulado SAE por meio de fluidodinâmica computacional

Abstract

The aerodynamic characterization is fundamental for the development of an aircraft project, since the coefficients raised are directly used in the performance, control, structures and stability calculations of the vehicle. The precision of the aerodynamic study directly influences the quality and reliability of the entire project. In this work, an aerodynamic investigation (in a computational way) of the conceptual wing of the aircraft used by the Zeus Aerodesing team in 2019 was developed. The profiles used in the study were the Selig 1223 and the profile developed by the team, named ED2. Using computational fluid dynamics software, XFLR5 and Ansys (fulent), simulations were carried out in different situations to evaluate the behavior of the wing with the aforementioned aerodynamic profiles and characterize it, obtaining the curve of its aerodynamic coefficients: Cl, Cd and Cm, in addition to observing its flow and stall. During the work, it was also possible to observe a deviation in the flow that was solved with the implantation of wingtip devices (endplates)
