As society continues to globalize and advance in complexity, the increased demand for business aviation has caused the global travel rate of airlines to increase with each year. With this continual increase in aviation travel, the Federal Aviation Administration (FAA) predicts that the fuel consumption rate is to increase by 1.6 percent as of the year 2025. While this increase in fuel consumption is a positive trait of a thriving aviation community, concerns also arise regarding increased greenhouse gas emissions and enlarged contributions to the greenhouse effect. The most prevalent greenhouse gases associated with jet engine emissions are water vapor, carbon dioxide, carbon monoxide, nitrogen oxides, and small soot particulates. A solution to this growing issue is the use of synthetic fuels as an alternative to traditional fossil fuels which emit significantly less greenhouse gases. The research performed in this paper found that the combustion of S8 produced greater magnitudes of vibrations than the combustion of Jet A but was also quieter and produced less emissions. Through the combustion process in the single-stage turbojet engine, S8 emitted 61.22% less water vapor, 5.31% less carbon dioxide gas, 18.18% less carbon monoxide emissions, 3.64% less nitrous oxide emissions, and lastly 133.33% less unburned hydrocarbons than Jet A.
