| Abstract | ||||
| The aim of this work is to study the dynamic aeroelastic behavior of slender composite swept wings using a modified equivalent plate approach. The present modified analysis incorporates transverse shear deformation and satisfies the shear stress conditions, which significantly improves the accuracy of thick wing results. This , analysis is used to study the problem of flutter of several slender, composite wings having different aspect ratios, taper ratios, sweep angles, numbers of layers and fiber orientations. Comparisons and conclusions regarding the influence of the above parameters on the wings' dynamic aeroelastic performance are presented. All analyses are confined to the incompressible flow regime. | ||||
