Modeling a Complex Aero-Engine Using Reduced Order Models
Gas turbine engines are widely used in many industrial applications and engine condition monitoring is a vital issue for the aircraft in-service use and flight safety. From the variety of condition monitoring methods, the model-based approach is perhaps the most promising for real-time condition monitoring. This approach can predict the engine characteristics at the expense of Ȝalgorithmic redundancyȝ and requires real-time simulation. The main obstacles for using full thermodynamic models in the engine condition monitoring schemes are high computing load, and inability to incorporate unforeseen changes.
