The FAA has released some details and photos as the first phase of testing draws to a close of four fuels designed to be a replacement for 100LL.
According to a report at AOPA.org, test rigs have been heated and cooled to extreme temperatures, fuel samples have been run through specially designed rigs replicating aircraft fuel systems on a bench, and ignition temperatures have been carefully measured, to name just a few of the tests designed to winnow down the candidate fuels that will be put through the second, and final, phase of testing that will begin in 2016.
That phase, which will include real-world testing in a variety of aircraft, is scheduled to conclude in 2018.
One year after four fuels were selected for testing as potential replacements for leaded avgas, progress remains steady, according to a report at AOPA.org, which notes that the first phase of testing should be completed later this year. Testing now is concentrated on material compatibility and rig testing, with the second phase of testing — in engines and aircraft — slated to begin in early 2016, according to the report.
“The FAA has said it hopes to have an unleaded replacement for avgas certified by 2018, and the program is on target to reach that goal,” the report concludes.
Working with avgas producers and distributors, Swift Fuels is making plans to supply unleaded 94 MON avgas to select regions in the United States and Canada. The premium quality unleaded fuel, tailored for lower-octane piston-engines, is already FAA certified and meets ASTM standards for aviation gasoline, according to company officials.
The fuel will not replace 100LL now sold at airports for high performance aircraft. [Read more…]
In the 1970s, the automotive world switched from leaded to unleaded fuels and the oil companies did a lot of research on knocking and how to prevent it. One of the big projects involved octane requirement increase (ORI).
In this program, cars were rated for octane requirement when new and then every 2,000 miles. The octane requirement increased until it leveled off at about 20,000 miles. [Read more…]
