Stress Analysis of Composite Aircraft Wing using Coupled Fluid-Structural Analysis

Aircraft wings are designed with very low factor of safety to keep the aircraft weight minimum. Thus, for safe design wings, stress analysis should be carried out under accurately estimated aerodynamic loads and this can achieved only through coupled fluid-structure analysis. Moreover, modern made laminated composite structures thus purpose study is employ ANSYS find best layup wing an that results in higher specific strength stiffness. Firstly, Computational Fluid Dynamics (CFD) has been actual load which pressure distribution around a three-dimensional wing. Then, from CFD was used as input detailed static structural Initially, stiffness isotropic evaluated then material changed laminates achieve better performance ratio. Stress different layups predict optimum high least it found symmetric cross-ply laminate performs best.
