Gas turbine performance calculations are either predictive or diagnostic. Predictive calculations tell what the gas turbine can do and diagnostic calculations tell how the engine is doing. Both types of calculations are inter-related in that the diagnostic calculation requires a predictive calculation to compare with so that a diagnosis can be made. Engine designers are primarily concerned with predictive calculations and users are concerned with the diagnostic calculations. This paper will show the development of a predictive calculation and how a diagnostic calculation can be coupled with the predictive calculation so that both the designer and user can take advantage of gas turbine performance code. The development of Dresser-Rand’s predictive code LGTP and Liburdi Engineering Limited’s LGTP-Health diagnostic code will be discussed as demonstration examples.
