Öz

In this study, performance evaluation of a turbojet engine designed for missiles and Unmanned Aerial Vehicles (UAV is done with exergy analysis methodology. Some exergetic performance assessment parameters are developed and used for this investigation.  These parameters help the engine designers to determine the levels of performance, sustainability and environmental impact of the new designed engine. The exergy efficiency,  the improved exergy efficiency, the waste exergy ratio, the fuel exergy waste ratio, the waste exergy improvement potential ratio, the productivity lack ratio, the fuel exergy improvement potential ratio, the waste exergy cost rate, the environmental effect factor, the ecological effect factor, exergetic sustainability index and sustainable efficiency factor are estimated to be 9.71%, 52.55%, 90.29%, 90.29%,  90.29%, 929.54%,  81.52%, 32.29x10^-3 kW/$, 9.295, 10.295, 0.108 and 1.108 for the maximum operation mode of the investigated turbojet engine, respectively. The analyzing results of exergetic performance indicate that the designers and researchers shall focus on the improvement of engine compressor and combustor to progress the exergy efficiency of engine and to decrease the environmental impacts of engine.
