摘　　要：为了加速涡轮气动设计过程,建立涡轮气动设计体系,完善涡轮设计平台,将NREC软件的涡轮一维、S2设计分析模块与NUMECA软件的三维造型、分析及优化模块通过编制程序实现数据自动转换,从而实现了一维、S2、三维的一体化设计。同时又实现了针对涡轮优化设计中存在不同问题的分层优化设计。并将其应用到某型涡轮的改型设计中,使得涡轮设计周期缩短,优化后效率较原型涡轮提高1%,并且具有优良的变工况性能。In order to accelerate turbine aerodynamic process,to build design system and to perfect design platform,data conversion automatically by a self-compiling program is realized,which join one dimensional,S2 module of NREC and three dimensional modeling,analysis,optimization of NUMECA together.So the integrated design is realized,which contain one dimensional,S2 and 3D design.At the same time,it can realize multilevel optimization design easily according to different questions.The system is used to redesign one turbine,the result indicate the periods of design was reduced,and after optimization the efficiency is improved about one percent,the performance under variable working conditions was perfect.
