The design method of three dimensional flow has recently been used to multi-stage compressors. This paper establishes the theory of three dimensional-flow design and introduces what blading gains the best total efficiency. The fact that the best total efficiency is obtained by the best stage one and the least pressure losses of before and behined guide vanes, and the best blade element efficiency is obtained by a flow pattern of 50% reaction and one-half velocity coefficient, is well known. Only by the use of non-uniform pre-moving and guide vanes, all 50% reaction and mean axial velocity uniform type blading is obtained. This blading shows the best total efficiency of all.
