Investigation of anti-wear properties of mixed aviation fuels based on ethyl esters of camelina oil

Abstract

Presented studies are related to the spheres of aviation and machine-building. Anti-wear properties of conventional jet fuel, fatty acids ethyl esters bio-additives derived from camelina oil and their blends were investigated experimentally. It was found that lubricity of bio-additive is significantly higher comparing to conventional oil-derived jet fuel. It was found that addition of bio-additive into the composition of jet fuel leads to strengthening of boundary film, decreasing of friction coefficient and improvement of anti-wear properties of fuel blends. The mechanism of fatty acids esters influence on improvement of anti-wear properties of jet fuel was substantiated. It was shown that camelina oil fatty acids esters positively influence on lubricating ability of oil-derived jet fuels and may be used in order to improve anti-wear properties of conventional jet fuels.
