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.
