Air Show Pilot Tests Unleaded Avgas In Radial Engine

WEST LAFAYETTE, IND. – An air show performer based in the northeast says a high-octane, unleaded aviation gasoline provides power similar to conventional general aviation fuel and provides increased aircraft range.

Rick Volker of Rick Volker Air Shows, Niagara Falls, N.Y., compared the performance of Swift Enterprises Ltd.’s 100SF gasoline with conventional 100LL in separate flights of his Sukhoi Su-26M. The flights included extensive use of full power and unusual attitudes to simulate air show flight. He said on-board engine monitoring supported test results.

“Swift’s 100SF provides similar power, but with less fuel burned at every power setting, which allowed for significant increases in aircraft range,” said Volker. “I tested the material compatibility of 100SF with the unmodified 360 horsepower Vedeneyev M14P engine and confirmed the miscibility with 100LL, meeting performance benchmarks at each trial. These tests provide supportive evidence that 100SF will meet the performance needs of aircraft during the most severe use imaginable, without any equipment changes.”
