摘　　要：涡轮叶片平面叶栅优化方法借鉴已有研究成果,综合考虑了造型方法、性能评估方法、优化方法三个关键环节,在i SIGHT平台下完成了叶栅优化过程集成,建立了适合工程应用的涡轮叶栅多目标优化设计系统。以高压涡轮导叶中截面为例,从参数敏感性、反设计及多目标优化三个方面,对优化方法进行了较为深入的分析。结果表明,该方法可快速有效地优化涡轮叶栅流场和性能。Based on the existing research results, a new turbine cascade optimization method was devel？oped, which was synthesized with the three key points： the cascade geometry design, performance assess？ment and optimization method. The integration of the optimization process was achieved in the iSIGHT plat？form. A multi-objective optimization design system of turbine cascade was established, which was suitable for the engineering application. Taking the middle section of a high pressure turbine cascade as an example, the further analysis was made in three ways： the parameter susceptibilities the inverse design of cascade and multi-objective optimization. The results indicate that the new method is able to optimize the flow field and performance of cascade quickly and efficiently.
