Environmental assessment of a micro turbojet engine with the aid of exergy
Özet
Environmental impact of the aviation industry has been an important issue in last decade. In order to decrease the environmental effect and to improve the efficiency of aero engines, one needs to understand the performance evaluation factors. As a case study, a small experimental turbojet engine developed in context of rapid growth of R/C aerial vehicle applications and small aerial vehicles is examined. Within this scope, the current paper discusses performance and environmental impact of a turbojet engine used on R/C unmanned aerial vehicles with the aid of exergy and emission paramaters. In the end of the study, major exergy, environmental and emission measures of the engine are revealed. Exergy analysis methodology is a well-accepted tool for investigation of energy conversion systems working in accordance with the thermodynamic principles. It helps to develop, assess and make improvements on them. So that, this exemplifying study may lead future studies on environmental impact assessment of various engine types that are still in service in the aviation industry
