Abstract :In this study, the effects of methanol, ethanol, isopropanol, and Diethylene glycol monomethyl ether (di-EGME) added to jet fuel in certain proportions on the properties of jet fuel such as density, viscosity, freezing point, and ignition point was examined. By adding 2%, 5%, 7%, and 10% of each additive to JP-8 fuel, the required mixture was obtained and tested in the relevant devices. As a result of the experiments, it was determined that the density value of JP-8 fuel was 797 kg/m3 and this value did not vary greatly in the mixed ethanol, ethanol, and isopropanol, but with the addition of di-EGME, it increased significantly and reached 814.5 kg/m3. It was observed that the viscosity value did not vary greatly with the addition of methanol and ethanol but increased to 1.298 mm/s2 with the addition of 10% isopropanol and to 1.98 mm/s2 with the addition of di-EGM. The ignition point value of JP-8 fuel, which is 46 °C, was measured to be 40 °C with the addition of 10% methanol, 43.4 °C with the addition of 10% ethanol, 42.9 °C with the addition of 10% isopropanol, and 55.4 °C with the addition of di-EGM. The freezing point value of JP-8 fuel, which is -56.7 °C, was measured as -61.7 °C with the addition of 10% methanol, -62.1 °C with the addition of 10% of ethanol, -57.6 °C with the addition of 10% isopropanol and -54.6 °C with the addition of di-EGM.
