| Timelines and examples of technologies |
Total Impact |
| Retrofits |
7 to 13% |
- Winglets mounted on the wingtips of aircraft reduce fuel burn with improved aerodynamics
- Engine components replaced by more advanced ones for better combustion and airflow
- Cabin retrofits with lighter materials for furnishing and less energy-consuming lighting and in-flight entertainment
|
|
| Production Updates |
7 to 18% |
- More airframe structure components made of lightweight composite material instead of aluminum
- Advanced engines for current aircraft production series
|
|
| New aircraft design around 2020 (incl. new single aisle aircraft) |
25 to 35% |
- Geared turbofan engine will reduce fuel burn 10 to 15%
- Open rotor engine will reduce fuel burn around 25%
- Counter-rotating fan will reduce fuel burn 10 to 15%
- Advanced turbofan will reduce fuel burn around 15%
- Laminar flow reduces aerodynamic drag by reducing turbulence on aircraft surface, 10 to 15% less fuel burn
|
|
| New aircraft design well beyond 2020 |
25 to 50% |
- Blended wing body, rather than classical tube & wing architecture
- Revolutionary engine architectures
- Fuel cell system for on-board energy
