The Tale Of The F-35 And Hot Jet Fuel 10 Dec 2014 By Colin Clark
"...“This is not an F-35 issue; there are no special restrictions on the F-35 related to fuel temperature. The F-35 uses the same fuel as other military aircraft. It can fly under the same temperature conditions as any other advanced military aircraft,” said Joe DellaVedova, program spokesman, in an email yesterday evening.
The folks at Luke say they are testing the new paint jobs to avoid problems, according to the AETC story: “‘It ensures the F-35 is able to meet its sortie requirements,’ said Chief Master Sgt. Ralph Resch, 56th LRS fuels manager. ‘We are taking proactive measures to mitigate any possible aircraft shutdowns due to high fuel temperatures in the future.'”
“Painting fuel trucks to reduce fuel temperature and improve aircraft performance will benefit legacy aircraft as well as F-35. There is no fuel temperature upper limitation on F-35 operations that would prevent sorties, and no sorties have been cancelled as a result of fuel temperature,” Kyra Hawn, deputy spokesman at the JPO, said in an email this morning. “Daily F-35 operations at Marine Corps Air Station Yuma, and Luke Air Force Base have been unaffected by hot environment or fuel temperature.”
The plane is now undergoing climate tests: heat, cold, rain, snow, ice etc. A lab test imposing temperatures in excess of 130 degrees was just completed “and the aircraft performed exceptionally well based on preliminary information collected,” Hawn wrote. Full climate results will be ready in the spring of 2015."
