Abstract
A great effort of aircraft industry has been developed to get more efficient and safer aircrafts. More modern aircraft are requested by airlines in all parts of the globe. Manufacturers, in turn, need increasingly skilled aerospace engineers. The main purpose of SAE Brazil Aerodesign competition is to design an efficient small aircraft. Computational Fluid Dynamics (CFD) can be an important tool on the design of aircraft components minimizing design time and costs. The knowledge flow details about an aircraft are necessary for the design of an efficient aircraft. The three dimensional flow about an aircraft wing can be computed using a CFD code. A design method, however, must be reliable and fast to allow comparing different geometries easily. In this work it is proposed the numerical study of the wing of an Aerodesign in order to predict the aerodynamic behavior of the wing in flight, analyzing the main parameters involved by two different methods, the Vortex Lattice Method and the Finite Volume Method. For the Vortex Lattice Method Athena Vortex Lattice (AVL) code was used. The ANSYS CFX code applied for finite volume method analyses. The domain was discretized by an unstructured grid. A shear stress (SST) turbulence model was chosen. Lift and momentum coefficients evolutions versus the angle of attack are presented and compared. Distribution of pressure and velocity on the surface of the wing computed by the ANSYS code are also presented.
