Turboshaft engines, one of the classifications of the helicopters, combine the core engine and fan and consume fossil fuels. Emissions, produced by the fossil fuels, cause global warming and environmental pollution, such as ecological, human health. To improve helicopter capability, energy is the first point of improvement. High-energy efficient helicopter engines help decrease the environmental damage. Exergy should be applied to the system to determine the maximum available energy. In this study, energy analysis and exergy analysis have been applied to a turboshaft helicopter engine. According to the result of this study, the maximum energy and exergy efficiencies are found to be 21.99% and 15.87%, respectively, at 1500 Shaft Horsepower (SHP). It is seen that the efficiencies increase with the increase of the engine power. Besides, exergy destructions and exergy loss values are presented by calculating different powers.
