Nonlinear Aeroelastic Characteristics of a Laminated Composite Wing Considering Compressible Shock Wave Effects

Abstract:

In this study, advanced computational analysis system for nonlinear static aeroelastic problems has been successfully developed by the composite structure (FEM)-fluid (CFD) combined method with internal iteration steps. Major focus of the present study is to investigate the static aeroelastic characteristics of laminated composite wings including the strong normal shock waves in the transonic and low-supersonic flow regions. The results importantly indicate that the effect of airfoil camber on the load distribution of laminated composite wing models can be nonlinear due to the variation of ply orientations.
