Results from international cooperation revealed

Using biofuels reduces jet engine emissions by more than half, a study has found.

Analysis of the research flights completed in 2013/14 by NASA, Germany’s DLR and the National Research Council of Canada (NRCC) showed an aircraft burning a 50-50 blend of aviation fuel and an alternative fuel of hydro processed esters and fatty acids produced from camelina plant oil reduced particle emissions from the exhaust by 50-70%.

The tests involved NASA's DC-8 and HU-25C Guardian, the DLR’s Falcon 20 and the NRCC’s CT-133.
