Application of Coons and Gordon Surface Modeling Apparatus in Reverse Engineering of Turbomachinery Components
The article discusses a pragmatic approach to surface modeling of turbomachinery components using the Koons and Gordon surface apparatus. These surface modeling techniques are used to prepare CAE models from highly detailed and often unusable computational models. A rationale is given for the usefulness of the Koons-Gordon algorithm in the field of turbomachinery, as well as its application in various geometric scenarios. A positive feature of the algorithm is the possibility of more flexible adjustment of models when new structural patterns are discovered during the development of a patch, having only four curves as input. The result is a 3D mesh generated from a set of surfaces. The motivation for the work was that at the moment there was no open source project capable of building such a mesh from a set of Coons patches. The presented Gordon surface interpolation algorithms are implemented and published in the open source CAD system “Analysis Situs”.
