Recently, as a result of the increasing use of fossil fuels in the world, environmentally friendly alternative fuel researches have become an important topic. The present study aims to examine the possible consequences of hydrogen fuel usage as an alternative fuel on the general performance, sustainability performance and environmental performance in the medium scale aircraft turboprop engine. Within this aim, a comprehensive exergetic analysis of the turboprop engine is conducted for both the hydrogen fuel utilization case and jet fuel utilization case. Then, depending on the fourteen performance metrics determined for the concept of the study, the effects of hydrogen fuel usage were observed. As per the results, the fuel mass stream rate reduces from 0.0145 kg/s to 0.052 kg/s compared to the jet fuel usage, while the stationary stream of air mass rate is 8.66 kg/s. Pollutant emissions mass stream rate decreases from 8.805 kg/s to 8.712 kg/s. The fuel exergy rate of the overall system rises from 6588.29 kW to 7002.36 kW. The product exergy rate of the overall system drops from 1135.928 kW to 1134.495 kW. The waste exergy rate of the overall system increases from 5452.36 kW to 5867.87 kW. While the exergetic sustainability index and sustainable efficiency factor of the system decrease from 0.21 to 0.19 and decrease from 1.21 to 1.19, the environmental effect factor and ecological effect factor of the system increment from 4.80 to 5.17, an increment from 5.80 to 6.17, respectively. The environmental effect factor of the overall system increment from 2.36 to 2.57, while the sustainable efficiency factor of the overall system reduces from 1.42 to 1.38.
最近，由于世界上对化石燃料的使用不断增加，环保替代燃料的研究已成为一个重要的课题。本研究旨在探讨在中型飞机涡桨发动机中使用氢气燃料作为替代燃料对其总体性能、可持续性能和环境性能的可能影响。在这一目标的指引下，我们对涡桨发动机的氢气燃料利用案例和喷气燃料利用案例进行了全面的热力学分析。然后，根据为研究概念确定的 14 项性能指标，观察了氢气燃料使用的效果。结果表明，与喷气燃料使用相比，燃料质量流率从 0.0145kg/s 降至 0.052kg/s，而静止空气质量流率为 8.66kg/s。污染物排放量质量流率从 8.805kg/s 降至 8.712kg/s。整个系统的燃料火用率从 6588.29kW 上升到 7002.36kW。整个系统的产品火用率从 1135.928kW 下降到 1134.495kW。整个系统的废火用率从 5452.36kW 上升到 5867.87kW。虽然系统的火用可持续性指数和可持续效率因子从 0.21 下降到 0.19，从 1.21 下降到 1.19，系统的环境影响因子和生态影响因子分别从 4.80 上升到 5.17，从 5.80 上升到 6.17，但整个系统的环境影响因子从 2.36 上升到 2.57，而整个系统的可持续效率因子从 1.42 下降到 1.38。
