Exergetic and exergoeconomic analysis of an Aircraft Jet Engine (AJE)
This study deals with energy, exergy and exergoeconomic analysis of an Aircraft Jet Engine (AJE) as named J69-T25A used on T-37B/C model training aircrafts. In the analyses, the engine data measured in the engine test cell at First Air Supply and Maintenance Center of Turkish Air Forces are used. Quantitative exergy and exergoeconomic cost balance equations are derived for each components of the engine and the overall J69-T25A engine. Exergy destructions within the engine components are investigated to determine thermodynamic inefficiencies. Cost balances and auxiliary equations are also applied to each components of the engine for observing cost formation. Additionally, exergy cost rate and unit exergy cost rate of each products of the engine are accounted.
