The US Air Force (USAF) F-15 Eagle tactical aircraft engine F100-PW-220, developed by Pratt & Whitney, has completed its first biofuel test flight at Eglin Air Force Base, Florida, US.
The flight test, powered by alternative jet fuel, supports the US Air Force’s goal of acquiring half of its domestic jet fuel from alternate sources by 2016.

The flight tests blended hydrotreated renewable jet (HRJ) with traditional JP-8 jet fuel, while ground testing included a blend of JP-8 jet fuel, HRJ and a synthetic fuel made from coal.
The test marks the completion of the second military engine ground and flight tests using biofuels, as the C-17 Globemaster III completed testing in August 2010.
Pratt & Whitney is planning to conduct similar tests for the F119 afterburning turbofan engine in the near future.
