Abstract: A optimum design method and the technical. Approach for dovoloping line the axial turbine stage are presented in this paper. This method is based on the theoretical research of the optimum design method for the each design parts in the axial turbine.The main design parts of an axial turbine stage containe the following subjects "The optimum selection of the geometrics of blade and meridional passage of the axial turbine stage", "Optimum Selection of the twist of the turbine blade", "The method of calculation of the optimum velocity distribution on arbitrary stream surface revolution for the compressible flu-I'd flow in the cascades of turbomachine", "The calculation method of surface coordinates of the cascades, it is based on the given distribution of velocity on the suction surface and distribution of she suction thickness", "the method of calculation of the surface coordinates of cascade. It is based on the optimum distribution of the surface velocity".
