Gripen fighter completes test flights using 100 percent biofuel
GKN Aerospace said the flight occurred late last month at Saab's facilities in Linköping, with both companies claiming the flights as the first time a single-engine fighter has flown with 100 percent biofuel. The fuel used is named CHCJ-5 and its interchangeable with normal jet fuel, so no changes to the engine are necessary for use. GKN said its RM12 engine demonstrated good performance during the biofuel flight. GKN, Saab and FMV, Sweden's defence procurement agency, will use the flight to show the potential of biofuel for military aerospace. (International Business Times)
