The aeronautical market is facing a continuous expansion and the competition among the main aircraft manufacturers is intensely growing. At the same time, climate changes have become a matter of serious concern for our society and stringent limitations on polluting emissions have been introduced. Therefore, great emphasis is placed on producing engines able to combine high efficiency with excellent performance and reliability. The engine's overall improvement comes from optimization of the key engine’s components from different engineering points of view; among them, Low Pressure Turbines (LPT) play a crucial role. The design process of an LPT involves many different disciplines (such as Aerodynamics, Vibration Mechanics, Aeroelasticity, etc.) and, consequently, many specifications must be taken into account.
