Development of the Generic Thermodymanic Turboshaft Engine Real-Time Simulation(TERTS) Model

摘要

The report describes the development of a turboshaft engine real-time simulationmodel. This model, denoted TERTS (Turboshaft Engine Real-Time Simulation), provides the programming environment MAT-LAB/Simulink with a model to predict steady state performance and transient responses of a generic turboshaft engine. TERTS is an off-design component stacking model, making it possible to build turboshaft engine models by arranging components according to the actual engine configuration. Off-design characteristics of the components are described either by thermodynamic relations or component maps. With these relations and maps internal processes in the engine are described. Effects of deviating operating conditions (a.o. flight conditions, customer bleed extraction, engine component degradation) are implicitly included.
