本文重点研究中程商用飞机发动机在恒定参考环境和地面运行条件下的能量可持续性指标。首先，根据发动机试验室参数对涡扇发动机进行了详细的火用分析。本文从可持续性考虑和热力学第二定律出发，提出了六个基于火用的可持续性指标。这里结合火用分析和可持续发展开发的涡扇发动机的指标是火用效率、废物火用比、火用破坏系数、可回收火用率、环境影响系数和火用可持续性指数。所研究的可持续指标是通过使用飞机地面运行条件的火用分析输出来计算的。研究结果表明，所研究的涡扇发动机的火用效率、废物火用比、火用破坏因子、火用可回收率、环境影响因子和火用可持续性指数值分别为0.315、0.685、0.408、0、2.174和0.460。这些参数预计将量化涡轮风扇发动机和飞机如何变得更加环保和可持续。
This paper focuses on the exergetic sustainability indicators of a medium-range commercial aircraft engine for constant reference environment and ground running conditions. First, a detailed exergy analysis of turbofan engine have been performed based on engine test cell parameters. Starting from the sustainability considerations and the second law of the thermodynamics, the paper presents six exergy-based sustainability indicators. The indicators of the turbofan engine developed here in conjunction with exergetic analysis and sustainable development are exergy efficiency, waste exergy ratio, exergy destruction factor, recoverable exergy rate, environmental effect factor, and exergetic sustainability index. The investigated sustainable indicators have been calculated by using exergy analysis outputs for aircraft ground running condition. Results from this study show that values of exergy efficiency, waste exergy ratio, exergy destruction factor, recoverable exergy rate, environmental effect factor, and exergetic sustainability index of investigated turbofan engine are found to be 0.315, 0.685, 0.408, 0, 2.174, and 0.460, respectively. These parameters are expected to quantify how the turbofan engine and aircraft become more environmentally benign and sustainable.
