Abstract

Exergo-environmental analysis is essential tool to detect cost-ineffective components and identify thermodynamic improvements which could promote the cost effectiveness of the overall propulsion and power systems. In this study, exergo-environmental index of a turboprop engine is evaluated by using energetic, exergetic and environmental methodologies at dynamic load conditions. Dynamic experimental data of the turboprop engine are obtained for six different torque values (at 240 Nm, 350 Nm, 485 Nm, 552 Nm, 580 Nm and 630 Nm). Results show that the highest component related total environmental impact rate is found at gas generator turbine with the value of 6.42 Pts/hr, while the lowest component related total environmental impact is at combustor as 2.44 Pts/hr at all torques. The highest and lowest environmental impact rates of exergy destructions are found for combustion chamber and power turbine as 31.30 Pts/hr at 630 Nm and 4.94 Pts/hr at 230 Nm, respectively.
