jetfuel

Jet fuel is a type of aviation turbine fuel used to power most jet aircraft. It is a kerosene-based fuel designed for high energy density and wide temperature operation.

The main civilian grades are Jet A and Jet A-1; Jet A-1 has a lower freeze point, making it suitable for international operations. Jet B is a more volatile blend used in certain cold-weather conditions but is less common due to handling hazards. Military aviation often relies on JP-8 or other jet fuels tailored to military aircraft and operations.

Jet fuel is produced from crude oil through refining processes that create a kerosene-range distillate. It is formulated with additives to prevent icing, improve stabilization, and reduce static electricity. Typical properties include a high energy content per unit volume, a flash point well above ambient temperatures, and a freezing point around -47 C for Jet A-1.

Regulatory standards set purity and performance requirements; civilian fuels adhere to ASTM D1655, with regional variants, while military specifications cover JP-8 and related grades. Aviation authorities require proper storage, handling, and quality control to prevent contamination and engine damage. Consumption contributes to greenhouse gas emissions, though sustainable aviation fuel blends are increasingly used to reduce lifecycle emissions.

The term Jetfuel is sometimes used in branding for non-aviation products, such as energy drinks or supplements, but these products are unrelated to aviation fuel. In aviation discourse, jet fuel or kerosene-type aviation turbine fuel is the accepted term.
