Peamainikütus

Peamainikütus, also known as main kerosene or jet fuel, is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is derived from petroleum and is a complex mixture of hydrocarbons, primarily paraffins and naphthenes. The specific composition of peamainikütus can vary depending on the intended application and environmental conditions.

The primary function of peamainikütus is to provide the energy required for aircraft engines to generate thrust. It is characterized by its low freezing point, high energy density, and good combustion properties. These characteristics are crucial for reliable aircraft operation, especially at high altitudes and in cold temperatures. Safety is also a paramount consideration, with strict standards governing its production, handling, and storage to prevent fires and explosions.

There are several grades of peamainikütus, with Jet A and Jet A-1 being the most common globally. Jet A-1 is widely used due to its lower freezing point compared to Jet A, making it suitable for a broader range of operating conditions. Another grade, Jet B, is a naphtha-kerosene blend used in extremely cold climates where a wider operating temperature range is needed. The choice of fuel grade depends on factors such as aircraft type, climatic conditions, and operational requirements. Peamainikütus is a vital commodity that enables modern air travel and global connectivity.
