Clean Sky Achievements

Clean Sky's projects are helping to dramatically slash the air industry's carbon dioxide (CO2), noise and nitrous oxide (NOx) footprints by developing new engine architectures (such as the open rotor), improved wing aerodynamics, lighter composite structures, smarter trajectories, and more electric on-board energy. The pictures below are some examples of cutting-edge technologies leading to those results.
