Abstract：The latest achievements and new theories of low specific speedimpellers hydraulic design is introduced synoptically. Different target impellersgeometric parameters calculation is analysed, such as the speed coefficient methodbased on the stat of a great deal of excellent hydraulic model, the resolutionmethod using computer to calculate impellers?geometric parameters. And especialvane drawing methods, such as single circular curve, same changed angle and differentchanged angel. Then benefit suggestions for research orientation of this kindimpellers?hydraulic design is supplied.
