Abstract

It is hard to achieve the low costs of the details of small series of their release at the high quality requirements while designing and manufacturing the details of the difficult geometrical form, such as impellers of turbo-machines. In this paper the ways of designing and manufacturing of impellers which allow cut down expenses on their producing in the conditions of a small batch production are stated.

Keywords:

turbo-machines, impellers, the MAI resource center, nonsteady turbulent flow, stereolithography, investment casting, electronic archive.
