 Advanced exergy analyses of an aircraft turboprop engine (TPE)Ozgur Balli Energy, 2017, vol. 124, issue C, 599-612 Abstract: A conventional and advanced exergy analysis of an aircraft turboprop engine is presented in this paper. In this framework, the main exergy parameters of the engine components are introduced while the exergy destruction rates within the engine components are split into endogenous/exogenous and avoidable/unavoidable parts. Also, the mutual interdependencies among the components of the engine and realistic improvement potentials depending on operating conditions are acquired through the analysis. As a result of the study, the exergy efficiency values of the engine are determined to be 16.63% at real case and 17.13% at unavoidable case, respectively. The system has low improvement potential because the unavoidable exergy destruction rate is 94%. The relationships between the components are weak since 86% of the exergy destruction is endogenous. Finally, it may be concluded that the air compressor, combustion chamber and power turbine components of the engine should be focused on according to the results obtained.
