Aircraft fuel consumption can be reduced by 15 per cent



Two aircraft engine concepts, geared turbofan and open rotor, can enable a significant reduction to aircraft fuel consumption. With open rotor, the potential reduction is 15 per cent. These are the findings of Linda Larsson, who has analysed and evaluated the two concepts.

​The average annual increase in passenger kilometres travelled by air has been 5.8% over the last 40 years, and fuel sales have increased by 2.2 per cent annually during the same period. New technological solutions are needed if aviation is to reduce its impact on the climate.
