PW engine powers biofuels test

A Pratt and Whitney F100-PW-220 engine recently powered its first biofuel test flight of an Air Force F-15 Eagle at Eglin Air Force Base, Fla. This flight test, powered by alternative jet fuel, comes on the heels of engine ground testing earlier this year at Arnold Engineering Development Center in Tennessee. The Air Force's goal is to acquire half of its domestic jet fuel requirements from alternate sources by 2016. This is Pratt and Whitney's second military engine to successfully complete ground and flight tests using biofuels. A C-17 Globemaster III powered by four Pratt and Whitney F117 engines completed testing in August. Similar tests are planned for the F119. Pratt and Whitney is a United Technologies Corp. company.
