Abstract : This paper presents a method that can be used to predict the post-stability operation of a turbofan engine and is based upon extending the capabilities of engine transient cycle decks. Typical predictions are presented and compared with results obtained from the testing of a modern augmented turbofan engine. The potential manners in which this new digital-computer-simulation tool may be used are also discussed.
