Design of Experiments to OPTIMIZE design solutions for a Power reduction Gearbox

Aeronautic market evolution is moving to geared engines since they generate promising architectures to reduce fuel consumption compared to turbofan engines. The Power transmission Gear Boxes (PGB) design is critical to increase the high power density at high operative speeds, and their design needs to increase the robustness taking into account the manufacturing tolerances especially under hyperstatic conditions, which may cause very sensitive variations.
