Abstract The sustainable developments of unmanned aerial vehicles in aviation industry show that the engine technologies including low altitude and power consumption in modern aircraft have been efficiently implemented. Otherwise, although electric motors are properly considered within this scope, they could not provide sufficient possible solution. However, recently, hybrid systems have been developed as related to reducing fossil sources. In all these studies, Small-scale engines stand out as reference motors for analysis. In this, the performance criteria of a flight process, and thermal and environmental performances of were examined as based on and exergy analyses. In these analyses, energy efficiency was found to be 38%, while the average exergy efficiency is 23.04%. According to the results, notably in the cruise and take off conditions, the engine has a significant loss capacity that reaches 60% in terms of improvement potential power effect. At the end of the study, some recommendations related to effective of the exergy approach for the engine performance was made.

考虑飞行过程的环境和热力学性能的小型涡轮喷气发动机评估

摘要 无人机在航空工业的持续发展表明，现代飞机的低空、功耗等发动机技术得到了有效实施。否则，虽然在此范围内适当考虑了电动机，但它们无法提供足够的可能解决方案。然而，最近开发了与减少化石资源相关的混合系统。在所有这些研究中，小型发动机作为分析的参考电机脱颖而出。在这方面，飞行过程的性能标准以及热和环境性能作为基础和火用分析进行了检查。在这些分析中，发现能效为 38%，而平均火用效率为 23.04%。根据结果​​，特别是在巡航和起飞条件下，发动机具有显着的损失容量，在改进潜在动力效果方面达到60%。在研究结束时，提出了一些有关火用方法对发动机性能的有效性的建议。
