Optimum Design of Aft-swept Composite Wings for Aeroelastic Characteristics with Structural Damping

Abstract

The present paper deals with the aeroelastic characteristics of aft-swept composite plate wings with structural damping. Based on the complex modulus approach, a minimum weight design of cantilevered laminated plates with a sweep-back angle under the flutter and divergence speed constraints is conducted by using a differential evolution in which lamination parameters are used as design variables.
