Keywords: aero-elastic tailoring, structure optimization, genetic algorithm, grid technology

The research is to analysis the coupling characteristic of unsymmetrical and unbalanced laminate and optimizes this structure for the wing aeroelasticity design. The Genetic Algorithm (GA) can solve the laminate optimization problem of the discontinuous variable and huge ply combination. A GA software system has been developed and used.
