Fluid–structure interaction is the interaction between movable or deformable part with the surrounding fluid. The surrounding fluid exerts pressure on the structure, thus causing it to deform, and the deformation of the structure in turn causes changes in the fluid flow. Fluid–structure interaction analysis is very important for the design of efficient and lightweight structure of various aircrafts components especially the wings. In order to calculate the aerodynamic forces, stresses, and frequency of different modes operating on the wing, a scaled-down model of a rectangular planform wing is created and static analysis is performed. Two materials are analysed: aluminium metal matrix composite and glass fibre reinforced polymer. The coupled mode analysis is performed and compared to see how the flow pattern and structure change when the wing is regarded flexible. The coupled mode analysis includes both one-way and two-way FSI analysis. The structural and fluent findings are evaluated independently. The analytical findings are compared to determine the best of the two materials mentioned in the present work. Furthermore, for a given loading and stress level, it is found that aluminium metal matrix composite deforms the least. Moreover, when the wing is viewed as a flexible structure, its aerodynamic characteristics are shown to decrease.
