A feasibility study on the use of ethanol/automotive gasoline blends in general aviation aircraft

Conference ·
OSTI ID:6819794
Considering the rising cost and diminished availability of 100-octane, low-lead (100 LL) aviation gasoline, owners of aircraft certified for 100 LL may be forced to find an alternative fuel in the near future. This study proposes a blend of 200-proof anhydrous ethanol ($1.70 per gallon) and automotive gasoline ($1.15 per gallon) as a replacement for aviation gasoline ($1.90 per gallon). The research program included materials compatibility tests, Cooperative Fuel Research engine tests, static thrust tests, and a flight test to determine the feasibility of such a blend as a fuel for an unmodified aircraft engine.
