A Conceptual Inventory of Entropy Management About Exergetic Sustainability Based on Different Cruise Altitude for Aircraft Engines

Although the aviation industry is working on versatile technological transformations, especially unmanned aerial vehicles, alternatives in current engine technologies are quite limited. In the development of areas where the use of innovative engine technologies, strategic evaluation paradigm is need as sectoral requirements, and the sustainability effects of environmental indicators are also important points that need to be addressed. In this process, performance evaluations of engines with different environmental impact processes gain importance. In this study, the effects of environmental sustainability depending on defined indicators are discussed over the performance of a turboprop engine depending on altitude conditions. The performance of the irreversible effects of the sampled PT6-21 turboprop engine at 15000–21000-ft cruising conditions was evaluated. In the analyses, irreversibility effects related to engine performance for three different ambient temperatures were examined and analyzed. At the end of this study, the effects of indicators on environmental performances were examined.
