N2 - Exergy analysis is a method of evaluation the proportion of each process on the transmission of system availability and also determination of ways through which the useful energy is lost. In this research, a turboprop engine is simulated by using GASTURB 10 commercial software which has developed based on zero-dimensional approach. The performance of turboprop engine is calculated at the design point and some off-design points, and afterwards thermodynamic properties of engine components at different flight altitudes and Mach numbers are calculated. Then, the necessary conceptual basis for exergy analysis, through the definition of exergy terms and using related exergy equilibrium equations, is introduced. At the end, thermodynamic data obtained from GASTURB software are used to exergy analysis of engine components. Results show that combustion process has the dominant portion of the system irreversibility.
