The present paper treats the flutter and divergence characteristics of composite plate wings with various sweep angles. In the second report of this paper, a minimum weight design of composite plate wings under the flutter and divergence velocity constraints is conducted by using a genetic algorithm in which lamination parameters are used as design variables. Aeroelastic analysis of composite plates is based on the finite element method and the subsonic unsteady lifting surface theory. The effectiveness of aeroelastic tailoring, which improves the aeroelastic characteristics of composite wings by the layup optimization, is demonstrated through the optimal results.
