摘　　要：An extremely simple,rapid and universal turbine cascade design program is develope d for contra rotating turbine cascades.With its simplest operating condition,only four data are necessary to be input for obtaining the geometry of a good enough cascade.They are just the input data for designing a cascade-the inlet Mach number and flow angle,the outlet Mach number and the specific heat ratio of working substance.Therefor e,it means that the design can be accomplished without any additiona l human decision.The program is based on the Mean-Stream-Line Method .It is given in detail how to select the independent design functions of this method in programming.This program enables to be operated with a very small computer,even a pocket computer such as the Sharp PC 1500.An extremely simple,rapid and universal turbine cascade design program is develope d for contra rotating turbine cascades.With its simplest operating condition,only four data are necessary to be input for obtaining the geometry of a good enough cascade.They are just the input data for designing a cascade-the inlet Mach number and flow angle,the outlet Mach number and the specific heat ratio of working substance.Therefor e,it means that the design can be accomplished without any additiona l human decision.The program is based on the Mean-Stream-Line Method .It is given in detail how to select the independent design functions of this method in programming.This program enables to be operated with a very small computer,even a pocket computer such as the Sharp PC 1500.
