ImpellerTool

The Problem

MAN Diesel & Turbo uses standardized impellers for their turbo compressors. Therefore, an automatic construction tool for these impellers is very useful.

The Solution

Based on a few characteristic inputs, the ImpellerTool can generate a full 3D model of an impeller in Siemens NX as well as additional data files for the fabrication.

For that purpose, based on the input all geometric dimensions were calculated or obtained from a data source. Then a master model will be cloned, and the expressions are replaced. In the end the freeform surfaces of the channels and blades are generated and exported with the NX Open interface.

Special Features

The tool is based on the BScript programming language. All geometrical calculations and the interaction with NX are done with the help of this scripting language.
