Assessment of Environmental Performance Indicators Based on Fuel Performance in an Aircraft Engine

This study aimed to observe the effects of fuel performance on the environmental performance indicators of an aircraft engine. For this purpose, three different fuels have been selected: JET-A, AVGAS, and natural gas. Afterwards, the performance of the fuels on three environmental sustainability performance indicators (environmental effect factor, sustainability index, and ecological effect factor) was obtained. According to the results, environmental indicator values were calculated with a value of 4.53 for the Jet-A fuel, 4.71 for the natural gas fuel, and 4.55 for the AVGAS fuel. Exergetic sustainability index values were obtained with a value of 0.22 for the Jet-A fuel, 0.21 for the natural gas fuel, and 0.22 for the AVGAS fuel. Ecological effect factor values were estimated with a value of 5.53 for the Jet-A fuel, 5.71 for the natural gas fuel, and 5.55 for the AVGAS fuel.
