Swedish aeronautics research for reduced climate impact

Publicerad 2018-07-13

In recent opinion piece published in Dagens Nyherer (DN.) Prof. Henningson and several other researchers (Tomas Grönstedt, Petter Krus, Anders Lundbladh and Sebastian Samuelsson) comment on efficient means for reduction of airtrafic impact on climate.

Global aviation is currently increasing faster than technology improvements, thus increasing CO2 emissions from the airplane. The Swedish debate focuses on restrictions on our flying through taxation and changing travel habits. The risk is that Sweden's greatest potential for reducing the impact of air traffic on the climate will completely end up in the shadow. We Swedes make up about 1.3 per mille of the world's population. Even though we fly significantly more than an average world citizen, the effect of our own flight is very small. On the other hand, effects of new technologies and innovations developed in Sweden can be seen globally and therefore have a greater chance of achieving a real environmental impact."

"What does Sweden do then? Two environmental initiatives where Swedish technology plays a key role is GKN 's work with open rotor and Saab's efforts in Blade . If open rotor engines are introduced, where the Swedish contribution is rotating light high-temperature structures, carbon dioxide reduces from the flight by 10-15 percent globally. This corresponds to 4-6 years of global technology development in the aeronautics field or Sweden's total annual carbon dioxide emissions! Bladedemonstrates how large composite structures allow air flow over the wings with much lower resistance. This technology can give up to 5 percent carbon dioxide reduction."
