P&W Military Engines Power F-15 Eagle On Alternative
The first biofuel test flight of a U.S. Air Force F-15 Eagle at
Eglin Air Force Base, FL was conducted recently using a Pratt &
Whitney F100-PW-220 engine. This flight test, powered by
alternative jet fuel, comes on the heels of engine ground testing
completed earlier this year at Arnold Engineering Development
Center in Tennessee. These tests directly support the U.S. Air
Force's goal of acquiring half of its domestic jet fuel
requirements from alternate sources by 2016.
This is Pratt & Whitney's second military engine to
successfully complete ground and flight tests using biofuels. A
C-17 Globemaster III, powered exclusively by four Pratt &
Whitney F117 engines, completed testing in August. Similar tests
are planned for the F119 in the near future. "We are pleased with
the performance of our military engines using alternate jet fuels
during ground and flight tests," said Bev Deachin, vice president,
Military Programs and Customer Support, Pratt & Whitney. "These
successful tests are in direct support of our U.S. Air Force
customer's goal to acquire and use alternate jet fuel sources for
The flight tests blended Hydrotreated Renewable Jet (HRJ), an
eco-friendly alternative from sources including animal fats or
plant extracts such as camelina, with traditional JP-8 jet fuel.
Ground testing also included a blend of JP-8 jet fuel, HRJ, and a
synthetic fuel made from coal.
