NASA and DLR Test Alternative Fuels
Working with the German Aerospace Center (DLR), NASA is studying the environmental impact of burning alternative fuels in jet engines. NASA supplied key instruments for DLR's Emissions and Climate Impacts of Alternative Aviation Fuels (ECLIF) experiments taking place in Germany this fall. Placed behind a parked DLR Airbus 320, these instruments measure the exhaust from the jet as it burns eight different types of standard and alternative fuels. They believe this research will help lead to more environmentally friendly aircraft designs and worldwide flight operations. The data will also help support information gathered during NASA's other alternative fuel research projects. The image shows one of a pair of NASA-operated sampling inlets behind the Airbus 320.
