Jet Engine Fuel

Aviation jet fuel, also known as turbine fuel or Avtur, is a highly refined kerosene-based fuel used to power jet engines in aircraft. It is a specialized type of fuel with specific characteristics like a low freezing point and high flash point, making it suitable for use in highaltitude and cold operating conditions. 

Here's a more detailed description: Composition and Properties:

• Kerosene-based: Jet fuel is primarily composed of kerosene, a type of petroleumbased fuel.

• Refined: It undergoes a rigorous refining process to meet specific quality and performance standards for aviation use.

• Additives: Various additives are included to enhance fuel performance and safety, such as preventing icing, corrosion, and static electricity buildup.

• Low Freezing Point: A critical characteristic is its low freezing point (e.g., -47°C for Jet A-1), ensuring it remains liquid at high altitudes where temperatures can be extremely low.

• High Flash Point: Jet fuel has a high flash point, meaning it requires a high temperature to ignite, enhancing safety.

Common Types:

• Jet A and Jet A-1: These are the most common types of jet fuel used in commercial aviation worldwide. Jet A-1 is favored for its lower freezing point.

• Jet B: This is a wider cut fuel, used in colder climates due to its even lower freezing point. Key Characteristics:

• Combustion: Jet fuel is designed for efficient combustion in gas-turbine engines, which are used in jet and turboprop aircraft.

• Specific Gravity: It has a specific gravity that is suitable for its intended use in aircraft. 


• Safety: Jet fuel is rigorously tested and controlled to ensure it meets strict safety standards for aviation.

In essence, jet fuel is a carefully engineered and highly specialized fuel that enables the safe and efficient operation of aircraft around the globe.
