Abstract (en)
The process involves choosing three reference sections (Sa-Sc) of a blade of a turbo machine vane along reference planes (Pa-Pc) corresponding to the base, middle and tip of the blade. The length of a land and a retreat distance for the sections are determined in the planes. Intermediate sections of the land and the disengagement of the land from the sections (Sa-Sc) are constructed by interpolation in the preset planes.
