The aim of this thesis work is the development of a tool (PRIME) able to make quick assessments of the mechanical response of a Low Pressure Turbine stage of aeronautical engines. It places itself in the preliminary design loops, giving aeromechanical feedback during the aerodynamic design, thus leading to an optimization process which includes both disciplines. The usual iterations between aerodynamic and aeromechanical design are reduced, allowing for a time effective process and a reduction of possible misunderstanding between the teams. The tool receives as inputs aerodynamic data, from which it generates the 3D airfoil, then it completes the CAD adding consistent inner and outer elements.
