摘　　要：将机翼外形参数化的思想和气动分析有效结合,在ISIGHT软件集成平台中同时实现三维外形建模、气动分析及其优化的全过程。探讨了机翼三维模型的自动化建模方法和解决方案,实现了机翼外形建模的完全自动化,并对实现机翼气动优化的相关算法进行了分析和研究。通过对机翼三维外形的自动调整和修改,在集成优化框架内,实现了气动性能的最优化,使得机翼气动分析更为快速、准确。气动优化过程中所构建的集成优化框架,可为机翼气动以及多学科优化的设计和研究提供新的解决方法和思路。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.
