Quantitative Assessment of Technology Impact on Aviation Fuel Efficiency

Abstract

In the e�ffort to implement the IATA four-pillar strategy for emissions reduction and in view of achieving the aviation industry's high-level goals for carbon emissions reduction, IATA launched its "Technology Roadmap for Environmentally Sustainable Aviation" (TERESA) initiative bringing together manufacturers, scientists, government agencies, infrastructure service providers and airlines. Under this initiative the German Aerospace Center (DLR) and the Aerospace System Design Laboratory (ASDL) of Georgia Tech conducted the screening, description, selection, modeling and assessment of appropriate technologies. The application of the technologies into reference aircraft on their particular mission was modeled. The results of this modeling were subsequently fed into a world fleet forecast model, which takes into account an updated calendar of future aircraft entry into service. Thus the model accounts for the eff�ects of CO2 reduction potential via technology introduction on world fleet level.
