Abstract
This paper develops a method to analyze usage and loss of thermodynamic work potential in vehicle propulsion systems. This method is then demonstrated on the Northrop F-5E propulsion system. The result is a thermodynamic 'loss deck' describing the partitioning of work potential usage (and loss) as a function of vehicle flight condition and engine power setting. Specifically, three loss deck formulations are demonstrated for the F-5E propulsion system: exergy, gas horsepower, and thrust work potential. Finally, these three loss decks are compared and contrasted to show their relative merits for propulsion system design and engine/airframe matching applications.
