上海汽轮机厂和上海发电设备成套设计研究所在引进美国西屋公司技术的基础上，运用ＣＡＤ技术进行汽轮机长叶片设计。该文主要介绍型面设计的ＣＡＤ系统。该系统已应用于上海汽轮机厂３００ＭＷ、６００ＭＷ机组末级９０５ｍｍ叶片，次末级４７４ｍｍ叶片，Ｓ７６００－１扭转静叶片系列及１ｍ长叶片的设计。图６ Shanghai Steam Turbine Works and Shanghai Power Equipment Institute of complete sets of equipment in the introduction of the United States Westinghouse technology, based on the use of CAD technology for turbine blade design. This article mainly introduces CAD system of profile design. The system has been applied to the design of the 905mm blade of the last stage of 300MW and 600MW units of Shanghai Steam Turbine Works, the 474mm blades of the second-and-last stage, the series of twisted blades of S7600-1 and the 1m long blade.
