Jet fuel, or kerosene, is a turboprop and turbojet aircraft engines not only fuel, but also the refrigerant and is used for lubrication of fuel systems. So he must have good anti-(characterized by a decrease of wear of the rubbing surfaces in the presence of fuel) and low temperature properties, high thermal oxidative stability and high specific heat value.

Modern aviation is mainly equipped with jet engines (WFD). In these engines, the fuel in the combustion chamber is fed continuously, and therefore the combustion process takes place continuously. Only to start the engine using extraneous ignition. Also continuously fed into the combustion chamber and the air WFD (required for combustion), pre-compressed and heated in the compressor. The combustion gases from the combustion chamber enter the turbine, where the thermal energy is converted into mechanical rotation of the turbine wheel from the shaft which drives the compressor rotor, as well as fuel and oil pumps. After the turbine combustion products in the form of a gas stream and pass the jet nozzle, it expands, creating reactive thrust force.

Basic properties of jet fuels:

  • Good volatility to ensure complete combustion;
  • completeness and high calorific value, predetermine range aircraft;
  • Pumpability and low temperature properties to provide the fuel in the combustion chamber;
  • Low tendency to form deposits, characterized by high chemical and thermal-oxidative stability;
  • Good compatibility with the materials: low anticorrosion properties to metals and lack of impact on the technical rubber products;
  • Good anti-wear properties, resulting in slight deterioration of parts of fuel equipment;
  • Antistatic properties, prevents the accumulation of static electricity, which provides fire safety when refueling aircraft.

Range, quality and composition of jet fuels

Jet fuel for planes produce subsonic aircraft to GOST 10227-86 and for supersonic aircraft to GOST 12308-89. According to GOST 10227-86 provides for production of five brands of fuel: TS-1, T-1, T-1C, T-2 and RT. According to GOST 12308-89 produce two grades of fuel: T-6 and T-8B.
