Which type of fuel is primarily used in turbine engines?

Turbine engines primarily use JP-8 kerosene as their fuel due to its specific properties that make it suitable for high-performance application and extreme conditions. JP-8 kerosene is a specialized military jet fuel that provides excellent performance at high altitudes and temperatures, making it ideal for aviation use.

The characteristics of JP-8 include a high flash point, low volatility, and excellent thermal stability, which are important for maintaining performance and safety in turbine engines. Additionally, this type of fuel contains additives that improve its performance, such as antioxidants, corrosion inhibitors, and anti-static agents, all of which enhance its operability in the demanding environments where turbine engines operate.

In contrast, petrol is more suited for piston engines and does not provide the necessary properties for turbine applications. Diesel fuel is also not suitable due to its higher viscosity and different combustion characteristics. Biofuels, while gaining attention in various applications for their renewable nature, have not been widely adopted in military turbine engines due to compatibility concerns and the need for stringent performance standards.
