Flights Using Biofuel

NASA and DLR Conduct Joint Research Flights Using Biofuel

The current research flights are taking place under the ACCESS-II project (Alternative Fuel Effects on Contrails and Cruise Emissions). The four research aircraft being used are flying in formation at typical commercial flight altitudes of between nine and 12 kilometres, headed by NASA’s four-engine DC-8. Behind the DC-8, the scientists on board the DLR Falcon and the NASA Falcon measure the composition of the exhaust gas at a distance of 100 metres to 20 kilometres. In addition, a Canadian National Research Council (NRC) T-33 is investigating the dynamics of the DC-8’s wake turbulence.
