- Jet fuel: Jet fuel is the most common fuel used in helicopters. It is a highly refined kerosene-based fuel that is specially designed for use in turbine engines. Jet fuel provides excellent performance and efficiency, and it is also relatively affordable.
- Gasoline: Some helicopters, especially smaller models, are powered by gasoline engines. Gasoline is a mixture of hydrocarbons that is commonly used in cars and other vehicles. It is less expensive than jet fuel, but it also provides less performance and efficiency.
- Diesel: Diesel fuel is another option for helicopters, especially for larger models. Diesel fuel is a heavier fuel than gasoline, and it provides more power and efficiency. However, it is also more expensive than gasoline and jet fuel.
- Biofuels: Some helicopters are being developed that use biofuels, such as ethanol or biodiesel. Biofuels are renewable fuels that are made from plant materials. They are more environmentally friendly than fossil fuels, but they are also more expensive.
