The paper deals with a hydraulic design of an axial propeller in function of pump and in function of turbine as well. A meridional cut of a turbo machine is proposed by classical method following guiding parameters.. Experimental findings about an interaction between parameters of the turbo machine in pump an turbine mode are implemented in this procedure. Blade cuts are proposed following NACA airfoils with using of their aerodynamic characteristics, which are processed numerically. Also Voznesensky diagram, which is used to predict an influence of an airfoil in a blade grid was processed numerically as well. The result is a complete design with text-file output, which is directly capable to be used as an input for 3D environment (e.g. CATIA). and Obsahuje seznam literatury a seznam symbolů
