During my work as a student-assistant at the Institute for Flight Propulsion at the Technical University of Munich I measured and digitalized the combustion chamber and the flameholder of the Turboshaft-engine Allison 250. These models were made in Catia V5 and took part in a research project. The picture in the middle on top shows the application-work of the CAD-model to the result of a laserscanner measurement (brown).
