Abstract: In this paper a scaled down model of a wing of rectangular planform is designed and the static analysis on the wing is carried out to determine the aerodynamics forces, stresses acting on it and the frequency of various modes. The iteration for the analysis is carried out for three materials namely, Aluminium 7075 T-6, Glass Fibre Reinforced Polymer and Aluminium Metal Matrix Composite. The analysis in the coupled mode is conducted and compared with the results obtained from that of static analysis to observe the changes in the flow pattern and how the structure behaves when the wing is considered to be flexible. In the coupled mode analysis 2 Way Fluid Structure Interaction analysis is carried out. The material properties and the results obtained from the analysis is compared to select the best out of the three materials. The change in the aerodynamic properties of the wing when it is considered to be flexible is also highlighted by a method of comparison. From the results obtained, it is observed that Aluminium Metal Matrix Composite has the least deformation for the same loading and can withstand higher stress. Hence, Aluminium Metal Matrix Composite exhibits better characteristics in comparison with Glass Fibre Reinforced Polymer and Aluminium 7075 T-6. Additionally, it is noticed that the aerodynamic properties of the wing is reduced when it is considered as a flexible structure. This can be highlighted by the 5.42% decrease in the L/D ratio between the CFD analysis and the 2 Way FSI analysis results.
