Design News - Engineering Materials - NASA Tests Biofuel, Reports Reduced Emissions via @designnews

The tests used a specially modified DC-8 aircraft that's been fitted out as a laboratory. A Falcon HU-25C trailed the DC-8 and measured its emissions, performance, and contrails for more than 15 hours. About 20 instruments sampled various characteristics of the gases, soot, and ice particles emitted by the DC-8. Two different fuels were tested: standard JP-8 jet fuel and a blend of 50 percent JP-8 jet fuel and 50 percent camelina oil-based fuel. Emissions were recorded at different altitudes, different distances between the planes, and different engine power settings. Four more hours of tests were completed on the ground.
