What is JP-4 made of?

What is JP-4 made of?

The composition of JP-4 is approximately 13% (v/v) aromatic hydrocarbons, 1.0% olefin hydrocarbons, and 86% saturated hydrocarbons (ITC 1985). It has a distillation temperature range of 60 to 270 °C (MacNaughton and Uddin 1984).

Is JP-5 a kerosene?

JP-5 is a specifically refined type of kerosene consisting of C9-C16 paraffins (53%), cycloparaffins (31%), aromatics (16%), and olefins (0.5%). The aromatic content of JP-5 might vary from less than 2.5% to greater than 22% by volume.

Is JP-8 a kerosene?

The JP-8 is a kerosene which contains additives with the objective of improving its properties for military use. As such, it is used in military aircraft with the exception of reactors loaded on aircraft carriers, which use JP-5. JP-5 is also a fuel derived from kerosene.

What is JP-4 fuel used for?

JP-4 and JP-7 (jet propellant-4 and jet propellant-7) are substances that are used by the U.S. Air Force as aircraft fuels. They are also called jet fuel-4 and jet fuel-7.

Is jet fuel made from kerosene?

Jet fuels are typically made by blending and refining various crude oil petroleum distillation products such as naphtha, gasoline, or kerosene in order to meet specific military or commercial specifications (Air Force 1989b).

What is the difference between JP-4 and JP-5?

JP4 and JP5 are jet engine fuels. JP4 is 65 percent kerosene and 35 percent gasoline, while JP5 is kerosene. AVGAS is used to power piston engines, while jet fuel is used to to power jet engines.

What is the difference between JP-4 and JP-8?

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. However, it also smells stronger than JP-4. JP-8 has an oily feel to the touch, while JP-4 feels more like a solvent.

What is the difference between JP-5 and JP-8?

The primary difference between the two military fuels is that the flash point temperature for JP-5 is higher (60°C) as compared to JP-8 (38°C). Jet fuels used for high performance military aircraft engines have even greater need of thermal stability as compared to commercial aviation fuels.

How many types of kerosene are there?

There are two types of kerosene that are used today. They are separated into type 1-K and type 2-K categories, based mainly on the difference in their sulfur content.

What kind of jet fuel is JP 4?

JP-4, or JP4 (for “Jet Propellant”) was a jet fuel, specified in 1951 by the U.S. government (MIL-DTL-5624 ). Its NATO code is F-40. It is also known as avtag. JP-4 was a 50-50 kerosene – gasoline blend. It had a lower flash point than JP-1, but was preferred because of its greater availability.

What kind of liquid is JP 4 and what is it made of?

JP-4 was a mixture of aliphatic and aromatic hydrocarbons. It was a flammable transparent liquid with clear or straw color, and a kerosene-like smell. It evaporated easily and floated on water. Although it had a low flash point (0 °F (−18 °C)), a lit match dropped into JP-4 would not ignite the mixture.

Why is JP4 called a wide cut fuel?

JP-4 is called a wide-cut fuel because it is produced from a broad distillation temperature range and contains a wide array of carbon chain-lengths, from 4 to 16 carbons long. It was initially developed for broad availability in times of need. The composition of JP-4 is approximately 13% (v/v) aromatic hydrocarbons, 1.0% olefin hydrocarbons,

What’s the difference between JP 4 and JP 8?

JP-4 was a kerosine/gasoline blend. JP-8 is a kerosine based fuel with the high altitude additives. You may buy the Air Force specification MIL-DTL-83133E, Turbine fuels, aviation, kerosene types, NATO F-34 (JP-8), and NATO F-35, and JP-8+100.
