Description	A reliable simulation model is an essential component of health monitoring system for gas turbine engines. Hence a thermodynamic simulation model of a twin spool gas turbine engine is being developed for use in an engine health monitoring (EHM) system. This model is based on mass and energy conservation principles across each component of the gas turbine engine. The model is being developed with limited design point information and measured gas path parameters available from the test bed. Both on-design and off-design models are being developed in Matlab® programming environment. Component characteristics maps available in the open literature are being scaled and used in the off design simulation. The scaling parameters used in the maps are tuned to improve the agreement between simulation model and data collected from engine test bed. Both tuned and un-tuned results of the simulation along with their respective errors are presented. The scheme to incorporate the model in the physics based health monitoring module is also briefly presented. Conf Name: ISSS International Conference on Smart Materials, Structures and Systems
