In an attempt to contribute to aircraft safety, it is fundamental to define the explosions conditions of kerosene vapor in an aircraft tank. Flammability properties of kerosene F-34 and F-35 have been determined experimentally. The flash point and the vapor pressure have been measured by means of an appropriate apparatus. A first analysis of the composition by GC-MS analysis shows four essential compounds: decane, dodecane, 1,2,4 trimethylbenzene and butylcyclohexane. The evolution of maximum pressure is compared with the theoretical values obtained with a simple model based on the theory of molecule collisions. A simple modelling has been developed as part of a novel study on ignition and combustion of classical propulsive powders and transposed to liquid kerosene droplets in order to predict the main characteristics of these explosions in a closed vessel.
