Powered by ANSI. Jet B is defined in ASTM D6615-15a(2019): Standard Specification for Jet B Wide-Cut Aviation Turbine Fuel. Aviation turbine fuel is a complex mixture composed mainly of hydrocarbons, but its exact structure varies depending on crude source and manufacturing processes used in its conception. Overall Ignition Delay (ms) Jet-A 1000/T C (K-1) (b) Jet Fuel/Air, O/F=13, P C =7 bar • First stage ignition delays for conventional jet fuels are similar. JP-8 is formulated with an icing inhibitor, corrosion inhibitors, lubricants, and antistatic agents, and less benzene (a carcinogen) and less n-hexane (a neurotoxin) than JP-4. Made for you. JP-8, or JP8 (for "Jet Propellant 8") is a jet fuel, specified and used widely by the US military. Grades of Jet Fuel. JP-5 has an even higher flash point of > 140 °F (60 °C), but also a higher cost, though the U.S. Navy Seabees still use JP-8 in their construction and tactical equipment. The U.S. Navy uses a similar formula, JP-5. While pure kerosene was once used to power the turbine engines of jet engines, jet fuel, which could be called an enhancement or adjustment of kerosene (or kerosine, as it is sometimes called in industrial or scientific usage), remains the means of powering commercial airliners and some other types of aircraft. h��V�OSW?�����|T��d����V>Ă��J L;B�Zq�U��tkt˘cN Turbine Fuel, Low Volatility, JP-7, commonly known as JP-7 (referred to as Jet Propellant 7 prior to MIL-DTL-38219) is a specialized type of jet fuel developed for the United States Air Force (USAF) for use in its supersonic military aircraft; including the SR-71 Blackbird and the Boeing X-51 Waverider. 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.. [7] Commercially, this additive is used in police helicopters in Tampa, Florida. • Overall ignition delays for all three jet fuels differ: S-8!��,х�q��[�Tjd:�'�Gr��A�_���L���٣��Z�w��;{�f [�+�

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.. A kerosene-based fuel, JP-8 is projected to remain in use at least until 2025. The U.S. Air Force replaced JP-4 with JP-8 completely by the end of 1995, to use a less flammable, less hazardous fuel for better safety and combat survivability.[1]. JP-8 has an oily feel to the touch, while JP-4 feels more like a solvent. Jet fuel, on the other hand, contains hydrocarbons more in the range of 12 to 15 carbon atoms. This fuel is used commonly outside of the United States. It is considered as a logistically friendly low-cost replacement of the JPTS fuel for the Lockheed U-2 airplane. h���;jBQ��9Ƿ�7!��`�R�و���`a��d��]*��!��kP�"�>X��������.�����9s��k�HX����JYu�Uw �8P}5���ߩt�P��U�{� *����ikrq`֛aʀ/WR\�m�*Gj*���8������ɖU[�6�ܷS��x ��k� mʣO����&T����ʩn�4�Y��2�ԁ���zq�*���)�hp{�(�zn�O͡#��d|o�#t蔈�q�H?�6R�m7��U��4*K.

For this reason, it is impossible to define the exact composition of jet fuel. The Kerosene/Jet Fuel category covers refinery streams and finished products commonly referred to by the generic term “kerosene”. The use of a single fuel greatly simplifies logistics. -l��ȇa�Y6�iFAmEA4��`&l����}���O����s�=����P џx xn_x����R�>�`�r��� �������*�P�����APTH�|����W�B�U, 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. JP-5, JP-8, AND JET A FUELS 145 4. The difficulty in establishing a relationship between fuel composition, flash point, and spark ignition hazard for a fuel like Jet A is due to a number of factors. However, by definition, the primary grades of jet fuel meet the specifications of ASTM D1655-20: Standard Specification for Aviation Turbine Fuels. Its NATO code is F-34. Because lubricity to the BOCLE method is not specified in MIL-DTL-83133G, modern common-rail diesel engines can experience wear problems in high-pressure fuel pumps and injectors. It was first introduced at NATO bases in 1978. It was specified in 1990 by the U.S. government as a replacement for government diesel fueled vehicles. ASTM D1655-20: Standard Specification for Aviation Turbine Fuels and ASTM D6615-15a(2019): Standard Specification for Jet B Wide-Cut Aviation Turbine Fuel are available on the ANSI Webstore. Nearly all jet fuel is made from kerosene derived from petroleum; however, a small percentage is made from oil sands (Chevron 2006). As you can see, the primary difference between these two fuel grades, which are both relatively high flash point distillations of the kerosine type and may derive from crude oil, natural gas, shale oil, or other sources, is their freezing point.
