A purpose of work is development of methods of geometrical design of meridional perimeter of multi-stage axial turbines and types of shoulder-blades of nozzles and workings, forming on the base of aggregate of flat cuts of spatial models of workings surfaces of shoulder-blades. A research method is a design of meridional perimeter and types of shoulder-blades with application of modern achievements of the applied geometry at presentation of aerodynamic perimeters and surfaces and computer graphics in relation to visualization of the got results on the personal computers. The questions of geometrical design of meridional perimeter of multi-stage axial turbines and types of shoulder-blades of nozzles and workings, forming on the base of aggregate of flat cuts of spatial models of workings surfaces of shoulder-blades are considered in work. For the construction of meridional perimeter of multi-stage axial turbines and types of shoulder-blades of nozzles and workings the linear, parabolic and cube laws of division of curvature are used. On the base of the offered method the programs of calculations are developed in the system of symbol (analytical) mathematics of Maple and geometrical mod-eling by the object-oriented language of Object Pascal in a visual programming of Delphi environment. Application of the offered methods of modeling of multi-stage axial turbines, will allow to promote efficiency of power transformations in their running parts. Used in industry of gas turbine.
