Abstract

The effects of air and fuel flow on the engine dynamic performance have been investigated. In part I, the mathematical model, that describes the engine parts and engine control systems, are presented. Herein, the dynamic performance for the studied engine due to the change of the air and fuel flow has been performed. Especially the effect of air flow instabilities on the studied engine performance has been investigated. It has been found that, the mis-synchronization between the air and fuel flow control has a significant effect on turbine inlet temperature. In case of air flow control failure, a sudden thermal failure of the engine parts may occur.
