The US Air Force has carried out a test run on a F110 bio-fuel engine, which could be used to power the F-16 Fighting Falcon.
The fuel comprises a 50/50 blend of JP-8 conventional aviation fuel and a bio-fuel derived from the seed of the camelina plant.
The test at Arnold Engineering Development Center (AEDC) is the first dedicated, uninstalled engine test conducted by the air force on hydro-processed renewable jet (HRJ) blended fuel.
It includes the overall engine conditions experienced in the full flight envelope, ignition light-off, throttle transients, augmenter lights and sequencing along with screech and rumble monitoring.
The data produced from the programme will be used to justify and support upcoming flight tests of the F-22, C-17 and the F-15.
During the test, the F11, along with the F100, were selected as they are considered the most challenging and the most fleet-representative engines across the air force.
The programme aims to complete certification of the air force fleet, including the F-16, for unrestricted use of the HRJ blended fuel by the end of 2012.
