was an early jet fuel [30] specified in 1944 by the United States government (AN-F-32). It was a pure kerosene fuel with high flash point (relative to aviation gasoline) and a freezing point of −60 °C (−76 °F). The low freezing point requirement limited availability of the fuel and it was soon superseded by other "wide cut" jet fuels ...
A diesel-fueled engine has no ignition source (such as the spark plugs in a gasoline engine), so diesel fuel can have a high flash point, but must have a low autoignition temperature. Jet fuel flash points also vary with the composition of the fuel. Both Jet A and Jet A-1 have flash points between 38 and 66 °C (100 and 151 °F), close to that ...
It had a lower flash point than JP-1, but was preferred because of its greater availability. It was the primary U.S. Air Force jet fuel between 1951 and 1995. MC-77 is the Swedish military equivalent of JP-4. [3]
It has a low freezing point of less than −110 °C (−166 °F) and the flash point is 130 °F (54 °C). The high energy density of 39.6 MJ/L makes it ideal for military aerospace applications - its primary use. The ignition and burn chemistry has been extensively studied. [8] [9] [10] The exo isomer also has a low freezing point.
A new jet fuel with a high flash point and high thermal stability was developed as the fuel had to be used as a heat sink for the severe high temperature environment in the aircraft. The Boeing X-51 Waverider also used JP-7 fuel in its Pratt & Whitney SJY61 scramjet engine, with fuel capacity of some 270 pounds (120 kg). [2]
The US Navy said it removed fuel from a reconnaissance jet that overshot a runway in Hawaii and went into an environmentally sensitive bay last week as it works to recover the plane.
Hygate estimates that if all usable UK sewage waste was put into making aviation fuel, it would still only meet 5% of the UK’s demand for jet fuel. Therefore, it would have to be used alongside ...
Jet-A powers modern commercial airliners and is a mix of extremely refined kerosene and burns at temperatures at or above 49 °C (120 °F). Kerosene-based fuel has a much higher flash point than gasoline-based fuel, meaning that it requires significantly higher temperature to ignite.
