“…The IGV command current is the main parameter that controls the position of the IGV. In the previous work [5], it was shown that (0.3A) is the mid-position current for the EHSA controlling the IGV. The maximum air flow rate is at zero current supplied to the IGV-EHSA where the actuator is fully extended.…”

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.

The dynamic performance of a turboshaft gas turbine engine is investigated in this paper. The air flows inlet to the engine and to the power turbine, are controlled by means of two guide vanes cascade. The displacement of the inlet guide vanes is controlled by means of two electrohydraulic servo actuators. The fuel flow rate is controlled by another electrohydraulic controller incorporating a series pressure compensated flow control valve. The equation describing the basic system subsystems and controllers were deduced and applied to develop a simulation program. The simulation program of the electrohydraulic servo controllers was validated experimentally. The engine dynamic performance is studied theoretically using the developed computer simulation program. Simulated results are shown for the transient response of the engine air and fuel flow control systems and its effect on the engine performance. The simulation results of engine air flow control show an agreement with the validated experimental results.
