Abstract
The application of advanced composites on the aerocraft structure can significantly reduce the weight, and improve the aerodynamic and flight performances. In this work, optimization design of a composite wing structure of a minitype unmanned aerial vehicle (UAV) is implemented. The parametric finite element model is established using parametric modeling technique for stress and stain analysis. The global optimal solution is guaranteed by the proposed two-step optimization search strategy combing genetic algorithm (GA) and sequential quadratic programming (SQP).
