采用商业优化设计平台iSIGHT FD，集成涡轮平面叶栅造型程序、叶片三维积叠程序、流道设计软件、网格划分软件TurboGrid、流场分析软件CFX，开发了涡轮三维叶片气动优化集成系统。该系统由流道优化集成系统、基准截面(根、中、尖)优化集成系统和三维积叠优化集成系统组成。采用该优化集成系统，对弹用发动机低压涡轮导向器进行了三维气动优化设计。结果表明：导向器叶片表面载荷分布明显改善；能量损失较原型降低约7%；在未改变低压涡轮转子的情况下，低压涡轮级气动效率略有提升。

Using commercial optimization platform iSIGHT FD, a 3D integrated aerodynamic optimization system for turbine blade is developed with different software and principles, such as ANSYS TurboGrid 13.0, ANSYS CFX 13.0, principles of stacked 3D turbine blade generator and annular cascades. The system consists of flow path optimization integration, the standard sections (root, middle and tip) optimization inte?gration and 3D stack optimization integration. The system has been applied to the 3D aerodynamic optimiza?tion design of a LP nozzle of a missile engine. The results show that the load distribution on blade surface had great improvement, about 7%energy loss was reduced comparing with the original design, and the aero?dynamic efficiency of LP turbine had a slight increase when the same LP turbine rotor was used.
