Scope The effort to develop greenhouse gas (GHG) free aircraft propulsion is gaining momentum. A major driver for this effort is the European and US funding to counter the impact of GHG emissions on climate change. While commercial aircraft currently contributes around 2.6% of the total GHG emissions in the US(#1), the 900 million tons of carbon dioxide (CO2) emitted globally per year will double by 2050 in the absence of significant measure to alter the source of aircraft propulsion(#2) and the consumed energy per flight. Every aspect of any significant improvement to aircraft design towards a carbon-free future will require significant developments in materials science and technology. The change to alternative fuels, e.g., sustainable biofuels, hydrogen or all electric propulsion will necessitate advances in new fuel generation, transportation onboard storage and compatible materials on the aircraft. Today, batteries do not have sufficient energy density to allow feasible long-distance air travel, and improving the battery chemistry and materials will be key to electric aircraft. Improvement to aircraft energy efficiency, e.g., more efficient engines, light weighting, or better aerodynamic characteristics will similarly require lighter weight materials with performance requirements at or better than currently available materials. Aerodynamic skins that minimize surface turbulence is another area of research for improving flight efficiency. The symposium will consist of sessions ranging from green chemistry, e.g., elimination of volatile organic compounds from aircraft manufacturing and maintenance, and energy efficiency, e.g., lighter weight materials and designs, and aerodynamic smoothing, and materials for non-fossil propulsion power.
