    The influence of oxygen concentration on the fire safety of aircrafts fuel systems
    (National Aviation University, 2019) Yefymenko, Valeriy; Kravchuk, Tetiana; Kovshun, Lidiya; Atamanenko, Natalya
    The aim of the work is to provide fire-explosion safety and to improve performance indicators of the jet fuels quality. The object of the study is the processes of air (oxygen) dissolving in fuels, determination of its concentration in the above fuel space of fuel tanks and creation of safe to ignite fuel-air mixtures. This problem is relevant due to the need to ensure the chemmotological reliability of aircrafts fuel systems. The subject of the study is fire-explosion safety of jet fuels RT (Jet A-1) and its connection with the presence of dissolved gases and gases in the above fuel space in fuel tanks. It has been determined the temperature limits of the formation of combustible fuel-air mixtures depending on the aircraft's flight altitude, temperature and changes in oxygen concentration in the abovefuel space.
