- a heat engine such as in particular but not limited to an airplane or rocket engine.
- jet fuels which are traditionally formulated from hydrocarbon cuts called kerosene cuts resulting from the distillation of crude oils.
- the reference jet fuel for civil aeronautics and the most widespread is Jet A-1. Its properties are defined in the international standard ASTM D1655. The physical characteristics of this fuel meet the efficiency and safety criteria required in the field of air transport, whether for ground operations or for flight phases. The main properties are: - A high calorific value, of at least 42.8 MJ/kg. It represents the quantity of energy released per unit mass of fuel during its combustion. This quantity is very important because it provides the aircraft with greater autonomy for a constant onboard mass.
- a very low freezing point which must be below - 47°C, which allows the fuel to be kept in a liquid state when the aircraft is in cruise flight, in a very low temperature environment.
- a flash point (or temperature above which fuel vapors can ignite in the presence of a flame), which must be greater than 38°C, in order to guarantee safe handling of fuel on the ground.
- Other properties such as sulfur content, acidity or fuel density are also defined in ASTM D1655.
