STUDY OF ANTI-WEAR PROPERTIES OF BLENDED JET FUELS BASED ON CAMELINA OIL ETHYL ESTERS

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.

Alternative Jet Fuel

The work is devoted to the development of alternative jet fuel blended with rapeseed oil-derived biocomponents and study of their physical-chemical properties. The modification of conventional jet fuel by rapeseed oil esters was chosen for this work among the variety of technologies for alternative jet fuels development. The main characteristics of conventional jet fuel and three kinds of biocomponents were determined and compared to the standards requirements to jet fuel of Jet A-1 grade. The most important or identifying physical-chemical properties of jet fuels were determined for the scope of this study. Among them are: density, viscosity, fractional composition, freezing point and net heat of combustion. The influence of rapeseed oil-derived biocomponents on the mentioned above characteristics of blended jet fuels was studied and explained.

Antiwear Properties

Antiwear properties of jet fuel, two kinds of biocomponents derived from rapeseed oil and their mixtures were investigated experimentally. Antiwear properties were estimated by the value of the scuffing load and the limiting load of scuffing applied to the friction pair working in a fuel medium. Biocomponents, mainly rapeseed oil FAME and rapeseed oil FAME modified via vacuum distillation were used during the study. It is found that lubricity of biocomponents is significantly higher comparing to conventional jet fuel. It is explained by the chemical composition of FAME: highly polarity of molecules stipulate their good adsorption at the surface of friction pair. High viscosity of biocomponents due to chemical structure positively influence on their lubricity. Adding biocomponents into jet fuel results in strengthening boundary film and thus improves antiwear properties of fuel blends. It is determined that FAME modified via vacuum distillation possess better lubricating ability comparing to standard FAME derived from rapeseed oil. Correlation between viscosity and lubricity of fuel is shown

AbstractContrail cirrus account for the major share of aviation’s climate impact. Yet, the links between jet fuel composition, contrail microphysics and climate impact remain unresolved. Here we present unique observations from two DLR-NASA aircraft campaigns that measured exhaust and contrail characteristics of an Airbus A320 burning either standard jet fuels or low aromatic sustainable aviation fuel blends. Our results show that soot particles can regulate the number of contrail cirrus ice crystals for current emission levels. We provide experimental evidence that burning low aromatic sustainable aviation fuel can result in a 50 to 70% reduction in soot and ice number concentrations and an increase in ice crystal size. Reduced contrail ice numbers cause less energy deposition in the atmosphere and less warming. Meaningful reductions in aviation’s climate impact could therefore be obtained from the widespread adoptation of low aromatic fuels, and from regulations to lower the maximum aromatic fuel content.
