In this paper, the thinking of the wing shape＇ s ics analysis. It＇ s in an integration software plafform--ISIGHT parameters combined effectively with the aerodynam- where achieving the entire process from three-dimensional shape modeling, aerodynamics analysis to its optimization. The method and solution formulas of the automatic modeling three-dimensional model of the wing were studied; While established an integrated optimization platform based on the ISIGHT software, and researched the relevant algorithm about the wing＇ s aerodynamics optimized. Within the framework of the integrated optimization, we achieve the most aerodynamic performance optimization through the automatic adjustments and modifications to the three-dimensional shape of the wing. We also make this analysis to the wing＇ s aerodynamics more quickly and accurately. The integrated optimization framework building in the aerodynamic optimization process can give new solutions and ideas to the optimization of wing aerodynamic and multidisciplinary design and research.
