The quantity to be added and approval for its use in various grades of fuel is strictly staj by the appropriate specifications. The water must be either demineralised or distilled and the only adulterant permitted in the methanol is up to 0. Some corrosion inhibitors also improve the lubricating properties lubricity of certain jet fuels. It can be used as an alternative to Jet A-1 but because it is more difficult to handle higher flammabilitythere is only significant demand in very cold climates where ddf better cold weather performance is important.
The power increase is achieved by cooling the air consumed, to raise its density and thereby increase the weight stwn air available for combustion. A few additives in common use are as follows: Military Jet-4 is the military equivalent of Jet B with the addition of corrosion inhibitor and anti-icing additives; it meets the requirements of the U. Jet A-1 and Jet A, both are kerosene type fuels.
Use of a corrosion inhibitor in power boost fluids supplied for these engines is not permitted. Jet Wtan and Jet A, both are kerosine type fuels.

Fuel System Icing Inhibitors Anti-icing additives reduce the freezing point of water precipitated from jet fuels due to cooling at high altitudes and prevent the formation of ice crystals which restrict the flow of fuel to the engine. There is another grade of jet eef, Jet B which is a wide cut kerosine a blend of gasoline and kerosine but it is rarely used except in very cold climates. Anti-icing additives can also provide some protection against microbiological growth in jet fuel.
Tetra-ethyl lead TEL is the only approved anti-knock additive for aviation use and has been used in motor and aviation gasolines since the early s.

Jet B is a distillate covering the naphtha and kerosine fractions. Civil Jet Fuels Aviation turbine fuels are used for powering jet and turbo-prop engined aircraft and are not to be confused with Avgas.
JP-5 JP-5 is a high flash point kerosene meeting the requirements of the U. Outside former communist areas, there are currently two main vef of turbine fuel in use in civil commercial aviation: Com All Rights Reserved.
Jet A-1 is a kerosine grade of fuel suitable for most turbine engined aircraft.
Similar injection systems are also incorporated in some turbo-jet and turbo-prop engines. Biocide additives are sometimes used to sef microbiological growths in jet fuel, often by direct addition to aircraft tanks; as indicated above some anti-icing additives appear to possess biocidal properties. Anti-oxidants prevent the formation of gum deposits on fuel system components caused by oxidation fef the fuel in storage and also inhibit the formation of peroxide compounds in certain jet fuels.
Corrosion inhibitors protect ferrous metals in fuel handling systems, such as pipelines and fuel storage tanks, from 918-7. Jet-8 is the military equivalent of Jet A-1 with the addition of corrosion inhibitor and anti-icing additives; it meets the requirements of the U.

This effect can be obtained by using water alone but it is usual to inject a mixture of methanol and water to produce a greater degree of evaporative cooling and also to provide additional fuel energy. It is widely available outside the U. Anti-knock additives reduce the tendency of gasoline to detonate. It is widely available outside the U.
Metal de-activators suppress the catalytic effect which some metals, particularly copper, have on fuel oxidation.

The methanol and water used must be of very high quality to avoid formation of engine deposits. Leave us a question or comment on Facebook. There is another grade of jet fuel, Jet B which is a wide cut kerosene a blend of gasoline and kerosene but it is rarely used except in very cold climates. This type of additive does not affect the freezing point of the fuel itself.
Static dissipater additives reduce the hazardous effects of static electricity generated by movement of fuel through modern high flow-rate fuel transfer systems. Jet-5 is a high flash point kerosine meeting the requirements of the U.
It can be used as an alternative to Jet A-1 but because it is more difficult to handle higher flammabilitythere is only significant demand in very cold climates where its better cold weather performance is important.
JP-8 JP-8 is the military equivalent of Jet A-1 with the addition of corrosion inhibitor and anti-icing additives; it meets the requirements of the U.
Aviation Fuel Home Aviation Fuel. Outside former communist areas, there are currently two main grades of turbine fuel in use in civil commercial aviation: Product Aviation fuel is a specialized type of petroleum-based fuel used to power aircraft; it is generally of a higher quality than fuels used in less critical applications such as heating or road transport, and often contains additives to reduce the risk of icing or explosion due to high temperatures, amongst other properties.
