Abstract: In this paper, theory, methodology and example application are developed and shown for a PW6000 high-bypass turbofan engine in terms of exergo-sustainable perspective. To obtain exergetic sustainability indicators, first, detailed exergy analysis is performed for the engine. The investigated exergetic sustainability indicators are exergy efficiency, waste exergy ratio, exergy destruction factor, environmental effect factor and exergetic sustainability index. These parameters are obtained as 29.7%, 70.3%, 59.4%, 2.367 and 0.423 for the engine at maximum take-off flight condition, respectively. Finally, these parameters are also expected to help understand the linkage between propulsion system design parameters and global aspects in terms of environmental impact and sustainable development and hence make the engine more environmentally benign and more sustainable.

Keywords: sustainability assessment; turbofan engines; exergy analysis; environmental impact; aircraft; sustainable development; propulsion system design.
