Abstract :
The sustainability performance of a jet engine was analyzed. To assess the jet engine’s performance, four different operations at part loads are implemented (part load-1, part load-2, part load-3 and part load-4). The energy and exergy rates of the jet engine parts were studied. Sustainability indicators were used to understand the operating performance of the jet engine. Five exergetic sustainability indicators, exergy efficiency, waste exergy ratio, exergy destruction factor, environmental effect factor and exergetic sustainability indicator, were used to examine the exergetic performance of four different loads. The compressor, combustion chamber, turbine and nozzle of the jet engine were investigated. The exergy efficiency of the jet engine took the maximum value at part load-3 as 7.8%. The minimum waste exergy ratio (0.9) and exergy destruction factor (0.9) were calculated at part load-4. The minimum environmental effect factor and maximum exergetic sustainability factor belong to part load-3 case. They were found to be 12.029 and 0.0831, respectively. The exergy destructions caused by the combustion chamber were the maximum above all. It can be inferred from the analysis that the more loading applied to the jet engine the more the exergy rate obtained. Thus the resulting exergy destructions become higher. They were calculated as 48.96 kW, 57.14 kW, 67.93 kW and 74.38 kW, respectively.
