Aeronautic Industry is working in the development and validation of new technologies related to gas turbines in
their whole life cycle; from design and manufacturing, to the more than three in service decades of operation which
are current values for this industry. For the Aeronautic Industry, and especially for the propulsion applications, the
first decades of the century are characterised by requisites for higher security, less contamination (both gases and
noise), and related to materials, energy and reduction of time-to-market values for new products. These necessities
are also shared both by Europe (“European Aeronautics: A Vision for 2020”) and the United States (“Aeronautics
and Space Transportation Technology: Three Pillars for Success, NASA Office of Aeronautics and Space
Transportation Technology”). Almost 40% of direct operating costs of long range aircrafts are related to their
engines.
