Fuels for turbojets, turbines, missiles and rockets

The jet A1 fuel is used by the jet-planes of the international civilian lines. The turbojet fuels of the national lines and military planes are very similar to the jet Al. 

This fuel is obtained from an atmospheric distillation of crude oil between 140-150 and 240-260°C. 

Compared with petrol and diesel fuels, the combustion of jet fuel takes place, not in a batch reactor, but in an open reactor, thus avoiding the occurrence of knock. Therefore, the problems connected with RON or cetane numbers, such as autoignition, do not impose stringent conditions on the chemical composition of jet fuels. 

These turbines are also called turboengines and they can function with a very large range of fuels e.g. NG, LPG, kerosene, diesel fuel. Kerosene is a middle cut in the atmospheric distillation of crude oil, in between petrol and diesel fuel. 

Missile turbojet fuels must, for reasons of space economy, possess a very high volume energy. The fuels RJ 4, 5 and 6 are used with the Ramjets, the fuels IP 9 and JP 10 for
