Total Impact |
| Retrofits |
6 to 9% |
- Winglets mounted on the wingtips of aircraft for improved aerodynamics
- Cabin retrofits with lighter equipment and furnishing materials for furnishing
- Less energy-consuming equipment (e.g. lighting and in-flight entertainment
- Drag-reducing surface coatings, such as riblets (“shark skin”)
|
|
| Production Updates |
8 to 20% |
- More airframe structure components made of lightweight composite material
- Active load alleviation
|
|
| New aircraft design until 2020 |
23 to 30% |
- Geared turbofan engine
- Counter-rotating fan
- Laminar flow (reducing turbulence on aircraft surface and thus aerodynamic drag)
|
|
| New aircraft design after 2020 |
25-40% |
- Advanced turbofan
- Open rotor engine
- Fuel cell system for on-board energy
|
|
| New aircraft design well beyond 2020 |
up to 50% |
- Blended wing body, rather than classical tube & wing architecture
- Revolutionary engine architectures
