Abstract:The rapid growth of the aviation sector around the globe has witnessed an overwhelming impact on fossil fuel resources. With the implementation of stricter environmental laws over emissions by conventional jet fuels, growing demand for research on alternative fuels has become imperative. One-hundred percent Synthetic Paraffinic Kerosene (SPK) and Fully Formulated Synthetic Jet Fuel have surfaced as viable alternatives for gas turbine engines due to their similar properties as that of Jet Fuel. This paper presents results from an experimental study performed on a small gas turbine engine, comparing emissions performance and vibrations for conventional Jet A-1 Fuel, thermally stressed 100% SPK and Fully Formulated Synthetic Jet Fuel. Different vibration frequencies, power spectra were observed for different fuels. Gaseous emissions observed were nearly the same, whereas, significant changes in particulates emissions were observed.

Stricter emissions legislation has driven the aviation industry to explore alternative fuels that can efficiently replace or blend with current Jet fuels. With this change it has become vital to investigate the effects of these fuels on combustion instabilities. In this study a recommissioned small gas turbine (Honeywell GTCP85 APU engine) has been used to test various blends of Jet A-1 and UOP along with four other novel fuels. A detailed analysis of vibrational response of these fuels upon combustion has been presented in this study. The study was conducted at the University of Sheffield's Low Carbon Combustion. The focus of this study is to investigate the vibrational response of different fuels and their compositions with varied aromatic content.
