Work Transfer Analysis of Turbojet and Turbofan Engines

Abstract

This paper explores the application of work transfer analysis to turbojet and turbofan engines. Emphasis is placed on understanding and applying the basic analysis method. The relationships between component performance and overall system work transfer are explored and demonstrated for ramjet, turbojet, and turbofan examples. The analysis results obtained via this method are quantified for a separate flow turbofan example. Finally, this paper suggests groupings of parameters of fundamental importance to turbofan engines based on the analysis results developed herein.
