The full inverse problem of axial flow cascade, to design an axial flow cascade with prescribed velocity distribution along the cascade blade, is solved with the Mean-Stream-Line Method (MSLM) originally proposed by Wu and Brown (1952). The selection of initial condition, the approach of iteration, the smoothing technique of calculation data, the determination of pitch/chord ratio and the applicable range of this method are discussed. Since this method is extremely simple and rapid, it is able to design a cascade very quickly and to program a design computer code with a very small computer. Some calculation examples are given and the calculation results are compared with other methods.
