Jet Fuel Overview
Jet fuel is a specialized type of aviation fuel designed for aircraft powered by gas-turbine engines. It is typically clear to straw-coloured in appearance. The two most commonly used fuels in commercial aviation are Jet A and Jet A-1, both produced according to standardized international specifications to ensure safety and performance consistency across the industry.
​
Jet A and Jet A-1 are widely recognized for their high energy content, clean combustion, and suitability for modern aircraft, making them essential for the global aviation sector.
Jet A-1 Fuel Efficiency and Combustion
Jet A-1 fuel has a specific energy of 43.1 MJ/kg, making it highly efficient for use in aircraft gas-turbine engines. Unlike diesel or gasoline engines, where combustion is intermittent, Jet A-1 fuel is continuously combusted in aircraft turbines, resulting in fewer residues.
​
The exhaust from jet fuel combustion primarily consists of carbon dioxide, water vapor, and hot air, with minimal particulate emissions, ensuring cleaner and more efficient energy production for aviation needs.
Jet Fuel: A Vital Transportation and Utility Fuel
Jet fuel is the third most important transportation fuel globally. As a middle-distillate product, it is primarily used to power commercial and military jets. Beyond aviation, jet fuel (in the form of kerosene) is widely used around the world for cooking and heating purposes, making it a versatile energy source in various sectors.
Jet Fuels Used in Aviation
Currently, aviation relies primarily on several types of jet fuels, including Jet A-1, Jet A (used predominantly in the U.S.), JP-5, and JP-8 (used for military aircraft). Additionally, Jet B and JP-4 are used as blends of kerosene with naphtha or gasoline, though they are less common. These various formulations are designed to meet the specific performance requirements of both commercial and military aviation.
​
Jet fuels, particularly JP-5, are highly flammable and insoluble in water. They may pose compatibility risks when exposed to strong oxidizing agents, such as nitric acid. In such cases, charring can occur, which may lead to the ignition of unreacted materials and nearby combustibles, creating potential fire hazards.
Proper handling and storage of jet fuels are essential to minimize these risks.
