Isometric conditions in shaping of shells stretch forming of double curvature minimum polythickness

First legitimately raised the question of the development of a specialized method of parametric representation of the surface shell of double curvature, which can be issued in the form of a theoretical drawing showing the laws of education in a particular coordinate system, for example, in the coordinate system of the main base of isometric coordinates. Transferring data between this system and the coordinate system adopted for the linkage of the product design can be achieved through a unified format to-computer exchange. The calculation method for shaping of shell stretch forming minimum polythickness is based on the optimization of the kinematic scheme consistent stitched associated with the approach of a certain degree of probability calculated thickness at characteristic points of the surface of the shell specified in the aircraft structure.
