Work continues toward alternative fuels

ARNOLD AIR FORCE BASE, Tenn. - An F-15 Eagle engine is undergoing performance testing using a unique blend of three different fuel types. The F100 engine is being tested with a combination of JP-8 conventional aviation fuel, a biofuel derived from an animal fat and a synthetic fuel derived from coal. The fuels testing is being conducted to ensure the different fuels, in varying combinations, are suitable for an upcoming series of F-15 flight tests tentatively scheduled for October at Eglin Air Force Base, Fla.
