The purpose of this thesis work concerns the development of a tool named PRIME, able to provide quick and easy aeromechanical feedback in the preliminary design of a low pressure turbine of aeronautical engines. This tool presents a considerable improvement in the preliminary design loops, thereby making the project process more robust and smart both on aerodynamic and aeromechanical side. The benefits are related to a reduction of misunderstanding and data exchange error beyond time and resources savings. The tool workflow begins with the 3D CAD airfoil creation, starting from geometry finalization handles in the Unigraphics NX environment, and considering parametric templates which represent mechanical arrangements on low pressure turbine stage outside the main flow paths.
