Abstract

The present project aims to perform a numerical study on the range of angles of attack (AOA) for unmanned aerial vehicles (UAV), specifically the study is performed for the UAV model E386; the numerical simulation is performed in the open source software, OpenFOAM, in addition to the aerodynamic analysis using different values of AOA. In chapter 1 the study of the Angle of Attack, the operational and geometrical characteristics corresponding to the Event E386 and the different turbulence models that exist in OpenFOAM such as the Spalart-Allmaras or SST model commonly used in the aeronautical industry due to the ease of application is carried out. Chapter 2 describes the methodology necessary for the development of the project, in this chapter, a case study is chosen to validate the computational domain necessary to simulate the wing profile of the Event E386, the construction of the mesh, the flight conditions, the boundary conditions and the configuration for the OpenFOAM software are defined. On the other hand, chapter 3 presents the analysis of the results of the previously defined simulations, in this case the lift and drag coefficients in the fixed wing of the UAV Event E386 are analyzed for different AOA. The critical AOA before the loss of lift is obtained, as well as the graphs that describe the aerodynamic behavior as a function of its aerodynamic coefficients. Finally, it presents the conclusions and recommendations obtained from the project.
