摘　　要：“七五”国家攻关课题中要求完成一个透平叶栅自动设计程序,在只输入叶栅进、排气拉瓦尔数λ_i与λ_e,进气角β_i及等熵指数k后,即能自动设计出良好叶栅。本文叙述如何利用中心流线法解析解来完成此任务。在用此法设计叶栅时。An extremely simple, rapid and universal turbine cascade design code is propo_ sed and programmed. With its simplest operating condition, only four data are necessary to be input for obtaining the geometry of a good enough cascade. They arejust the input data for designing a cascade--the inlet Mach number and flowangle, the outlet Mach number and the specific heat ratio of working substance. Therefore, it means that the design can be accomplished without any additional human decision. The programme is based on the Mean-Stream-Line Method. It is given in detail that how to select the independent design functions of this method inprogramming. This code can be operated with a very small computer, even a pocket computer such as the Sharp PC-1500.
