CoolingGen - A parametric 3D-modeling software for turbine blade cooling geometries using NURBS

Abstract

The generation of cooling geometries within turbine blades is an important aspect of jet engine design and research. Generating such geometries with conventional CAD tools is very time-consuming. CoolingGen is a fully parametric CAD tool for the fast creation of cooling geometries within turbine blades. Due to its parametrization, there is a semantic interface between user input and mechanical function, which is not given in conventional CAD tools. In this thesis, the theoretical and practical aspects of parametric geometry generation with CoolingGen are highlighted. It serves as a manual of important geometric methods and processes within CoolingGen.
