Resumo: The present work describes the integration of a non-linear Vortex Lattice Method (VLM) aerodynamic solver and an Equivalent Plate Model (EPM) structural solver, culminating in an Aero-Structural tool capable of analyzing wings. The aerodynamic and structural tools used in the Aero-Structural solver are described and validated, using experimental and numerical data. The aerodynamic model is expanded with the decambering approach, in order to allow for non-linear wing characteristics to be computed. This solver showed good agreement with experimental data both in linear and in non-linear regimes. The structural solver revealed good agreement with Finite-Element calculations, in both static load deformation and modal analysis. After describing and validating the two disciplines, the coupling between aerodynamic and structural solvers is described. A rectangular wing composed of skins, spars and ribs is analyzed using the present Aero-Structural solver. An experimental validation of the program developed is carried out. To accomplish this, a rectangular wing made with aluminum and PVC foam is built and tested in a wind tunnel. To measure wing deformations under aerodynamic loading, an in-house fully automated measurement system was developed using a laser measuring sensor and linear-guides actuated by stepper motors. The results showed a general good agreement between the deformation calculated with the numerical model and the data collected from wind tunnel testing. Some sources of experimental errors are identi ed and some enhancements are proposed.
