Multidisciplinary Robustness Evaluations of Aero Engine Structures

This paper presents a case study made to investigate the functional robustness of a jet engine turbine frame. Using virtual tools, a multidisciplinary analysis involving eight disciplines is performed on 50 non-nominal geometries. These geometries are obtained by varying the positions of the locators in the locating schemes on some parts of the assembly. Results show that geometrical variation can significantly affect the structural stresses on the product, and should thus be investigated further.
