Abstract

Abstract

The aim of the present study is to solve the control effectiveness problem in aft swept wing design by aeroelastic tailoring of the composite skin. Parametric analysis was carried out for the ply stacking ratio and thickness of the composite skin to study the influence on the static strength and control effectiveness. Based on the parametric trends obtained, a novel engineering strategy was proposed to reduce the weight of composite skin while keeping the control effectiveness. With such strategy, ply stacking ratio and the composite skin thickness were selected as design variables, and the objective function was the lowest skin weight considering the static strength constraint under critical load case and the control effectiveness constraint under typical flight condition. The optimization problem was solved successfully by MSC.Nastran SOL 200 solver for aeroelastic tailoring of an aft swept wing with composite skin.
