A research campaign to test the suitably of sustainable aviation fuels (SAF) as the energy source for single-aisle airliners has been launched at Toulouse in France. The campaign will involve both ground and flight tests and is being jointly conducted by aircraft groups Airbus and Dassault Aviation, aeroengine company Safran, French national aerospace research centre ONERA and the French Ministry of Transport. The SAF is being supplied by Total Energies. The German Aerospace Centre will also be involved. On Thursday, an Airbus A319neo single-aisle airliner started the test campaign with a flight from Toulouse, during which one of its two CFM LEAP-1A engines was operated using only 100% SAF. (The suffix –neo stands for new engine option.) The test programme is designated VOLCAN, a French language acronym derived from a phrase which translates as ‘Flight with New Alternative Fuels’.
