Aileron Reversal of Nonuniform and Swept Composite Aircraft Wings

In this paper, an analytical study on the aileron reversal characteristics of the anisotropic composite swept wings of aircraft via the extended Galerkin method is presented, and the wings are modeled as nonuniform, thin-walled beams with bending–twist structural couplings induced by a circumferentially asymmetric stiffness configuration. For this study, nonclassical parameters such as warping restraint, transverse shear flexibility, and bending–twist structural coupling are incorporated. Further, design parameters of wings such as taper and aspect ratios, sweep angle, initial angle of attack, aileron deflection, and ratios of spanwise and chordwise lengths of the aileron to the wing are newly investigated. The results of this study could play an important role in more efficient designs of composite thin-walled swept wings.
