Abstract: During the 40th Session of the Assembly of the International Civil Aviation Organization (ICAO), the Member States requested a feasibility assessment of a long-term global aspirational goal (LTAG) for international civil aviation in three sectors: technology, fuels, and operations. ICAO’s Committee on Aviation Environmental Protection (CAEP) organized a Technology Sub-group to better understand future evolutionary technologies for airframes, propulsion systems, and advanced concepts (including energy storage) up to 2050. Scenarios were analyzed to understand the impacts on CO2 emissions, costs, and investments, as well as potential implications on aviation growth, noise, and air quality. Professor Dimitri served as co-chair of the Technology Sub-group and under his direction the Aerospace Systems Design Laboratory conducted research in support of this study.
In this presentation, Professor Mavris will provide the technological perspective of LTAG with a high-level overview of the integrated results. The LTAG methodology involved three main steps including creating the technology reference aircraft, assessment of advanced tube and wing configurations, and assessment of advanced concept aircraft. A detailed methodology was developed and the international community was engaged to determine the potential of airframe and propulsion technologies possible up to 2050. Advanced tube and wing aircraft have a clear potential to improve the fuel (energy) efficiency of the international aviation system with some incremental contribution from aircraft with unconventional configurations, within the time frame considered for the study. While the integrated scenarios (technology, fuels, and operations) show the potential for substantial CO2 reduction, none of the scenarios reach zero CO2 emissions by 2050, but a carbon neutral growth could be achieved.
Bio: Dimitri Mavris earned his B.S. (1984), M.S. (1985), and Ph.D. (1988) in Aerospace Engineering from Georgia Tech. He is the Boeing Chaired Professor of Advanced Aerospace Systems Analysis in Georgia Tech’s School of Aerospace Engineering, Distinguished Regents Professor, and an S.P. Langley NIA Distinguished Professor. He is the Director of the Aerospace Systems Design Laboratory (ASDL) and Executive Director of the Professional Master’s in Applied Systems Engineering program. Prof. Mavris is a Fellow of the American Institute of Aeronautics and Astronautics (AIAA) and a Fellow of the Royal Aeronautical Society. He is President of the International Council of the Aeronautical Sciences.
