What type of fuel is commonly used in gas turbine engines?

Gas turbine engines primarily utilize jet fuel, notably Jet A or Jet A-1. This fuel is specifically designed for aviation applications and possesses characteristics that make it ideal for high-performance engines, such as a high energy content, low freezing point, and stability at high altitudes. Jet fuel ensures optimal combustion efficiency, reliability, and performance in various operating conditions encountered by gas turbine engines, including those in commercial aviation, military applications, and power generation.

While diesel fuel and biodiesel can be used in some specific applications and modified turbine engines, they are not the standard choice for most gas turbine engines, particularly in aviation. Gasoline, while commonly used in piston engines, does not meet the requirements for gas turbines and can result in poor performance or potential damage to the engine. Therefore, jet fuel is the most suitable and widely accepted fuel type for gas turbine engines.
