Application of Infrared Spectrometry in Studying Fuels and Biofules for Aircraft Turbine Engines

The research paper presents hydrocarbon biocomponents approved for use in aircraft turbine engines. The properties of these biocomponents are governed by ASTM D 7566 standard. One of the new issues regarding the utilization of fuels for aircraft turbine engines is the identification of non-petroleum elements, including hydrocarbon biocom-ponents. This article proposes applying infrared spectrometry as a technique for in-strumental analysis, which enables quick and qualitative identification of a used hydro-carbon biocomponent. Differences in the infrared spectrum between the mineral fuel and used fuel biocomponent were indicated based on the conducted preliminary tests
