Gas turbine engine performance model applications using an object-oriented simulation tool

Engine performance models are used throughout the life cycle of an engine from conceptual design to testing, certification and maintenance. The objective of this paper is to demonstrate the use and advantages of an engine performance model, developed using an object-oriented simulation tool, for the following applications: center dot Building an engine model from existing engine components and running steady state and transient calculations center dot Development and integration of a new cooled turbine component in the existing engine model center dot Accessing the engine model from an external application center dot Using an external legacy routine in the engine model
