NASA continues renewable fuel tests

By Staff | June 05, 2014

NASA is continuing its biojet testing initiative. In April, NASA announced it has signed separate agreements with the German Aerospace Center and the National Research Council of Canada to conduct a series of joint test flights to study the atmospheric effects of emissions from jet engines burning alternative fuels.

The Alternative Fuel Effects on Contrails and Cruise Emissions (ACCESS II) flights are set to begin May 7 and will be flown from NASA's Armstrong Flight Research Center in Edwards, Calif. NASA's DC-8 and HU-25C Guardian, DLR's Falcon 20-E5, and NRC's CT-133 research aircraft will conduct flight tests in which the DC-8 engines will burn a mix of different fuel blends, while the Falcon and CT-133 measure emissions and observe contrail formation.

According to NASA, ACCESS II is the latest in a series of ground and flights tests that began in 2009. ACCESS I testing was conducted in 2013 and indicated that tested biofuel blends may substantially reduce emissions of black carbon, sulfates and organics.
