The FAA found Swift Fuel to have a motor octane number of 104.4, 96.3% of the energy per unit of mass, and 113% of the energy per unit of volume as 100LL, and to meet most of the ASTM D910 standard for leaded aviation fuel. Following tests in two Lycoming engines, the FAA concluded it performs better than 100LL in detonation testing and will ...
One is referred to as the "aviation lean" rating, which for ratings up to 100 is the same as the MON of the fuel. [12] The second is the "aviation rich" rating and corresponds to the octane rating of a test engine under forced induction operation common in high-performance and military piston aircraft.
An aviation fuel truck of Shell At some airports, underground fuel pipes allow refueling without the need for tank trucks. Trucks carry the necessary hoses and pumping equipment, but no fuel. Aviation fuels are petroleum-based fuels, or petroleum and synthetic fuel blends, used to power aircraft.
Jet fuel or aviation turbine fuel (ATF, also abbreviated avtur) is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification.
In the United States and Canada, octane ratings are in AKI, commonly shown as "(R+M)/2". All states require gas pumps to be labeled with the correct octane level and nearly all states do regular testing to make sure gas stations are in compliance. A minimum 82 octane fuel is recommended for most vehicles produced since 1984.
JP-8, or JP8 (for "Jet Propellant 8"), is a jet fuel, specified and used widely by the US military.It is specified by MIL-DTL-83133 and British Defence Standard 91-87, and similar to commercial aviation's Jet A-1, but with the addition of corrosion inhibitor and anti-icing additives.
By increasing efficiency, a lower cruise-speed augments the range and reduces the environmental impact of aviation.According to a research project completed in 2024 and focusing on short to medium range passenger aircraft, design for subsonic instead of transonic speed (about 15% less speed) with turboprop instead of turbofan propulsion would save 21% of fuel compared to an aircraft of ...
The desire for a less flammable, less hazardous fuel led the U.S. Air Force to phase out JP-4 in favor of JP-8; the transition for USAF operations in Great Britain was made in 1979, and the change was completed throughout the USAF by the end of 1995. [2]
