Jet Fuel
Specialized aviation fuel for gas-turbine engines, optimized for high-altitude performance and extreme cold.
Overview
Jet fuel is a specialized type of aviation fuel designed for use in gas-turbine engines. It is colorless to straw-colored and consists mainly of hydrocarbons. Jet fuel offers high energy density, excellent cold-weather performance, and stability at high altitudes. The most common types are Jet A and Jet A-1, which are kerosene-based fuels used in commercial aviation worldwide. In Russia, TS-1 is the primary grade.

Quality Requirements
Must meet strict international standards such as ASTM D1655 (Jet A/A-1) or Russian GOST 10227 (TS-1). Key parameters include flash point (for fire safety), freezing point (to prevent fuel line blockage at high altitudes), thermal stability (to prevent coke formation in engine nozzles), and strict limits on sulfur, water, and particulate matter.

775 - 840 kg/m³
Freezing Point
Max -47 °C (Jet A-1) and Max -60 °C (TS-1)
Flash Point
Min. 38 °C (Jet A-1) and Min. 28 °C (TS-1)
Sulfur Content
Max. 0.25 % (Jet A-1) and Max. 0.20 - 0.25 % (TS-1)
Applications
Jet fuel powers commercial airliners, military aircraft, private jets, and helicopters. It is the primary fuel for gas-turbine engines globally.
Advantages
- High energy density for long-range flights
- Excellent cold-weather performance
- Stability at high altitudes
- Well-established global infrastructure
- Consistent quality standards
Challenges
- Significant carbon emissions
- Dependence on fossil fuel sources
- High production and refining costs
- Environmental impact concerns
- Limited sustainable alternatives currently
Future Outlook
The aviation industry is actively developing Sustainable Aviation Fuels (SAF) from biomass, waste oils, and synthetic processes. These alternatives can reduce lifecycle carbon emissions by up to 80%. Electric and hydrogen aircraft are also in development for short-haul routes.
