Abstract: The gas turbine-burner engine was first proposed by Professors Liu and Sirignano in 1999. A detail exergic analysis was performed on this engine. A turbofan engine core was used as a study system for this analysis. The first and second principles of thermodynamics were applied to each component of the system. An exergy balance was derived for each component of the system. An exergetic analytic study was performed to each component and the results were compared. Results show the combustor having the highest exergetic value. A comparison of the exergy of the conventional and the turbine-burner engines was completed based on ideal gas and reversible process assumption. Results shows less than 5% increase in the exergetic value of the turbine-burner to the conventional turbine.
