【Abstract】 In order to raise the accuracy and speed of the hydraulic design of the axial flow runner blades, the paper developed a runner CAD system. The selection of tool and the thinking in system development is introduced, and the main function of each mold of the CAD system and the relation of them issketched. An example of a hydraulic design, done with the help of the CAD system, for a runnerblade with given hydraulicparameters of a real power plant is presented. The example indicates that the proposed version is feasible and the CAD system is reliable, time saving, accurate and the blade’s appearance is amiable.The CAD system is important and valuable for the axial flow runner blades hydraulic design in our country.更多还原
