MULTIVARIANT SET POINT USING N1 AND N2 FOR ENGINE CONTROL

摘要

A turbofan engine throttle control system (10) and method for eliminating dead bands in the throttle control by decreasing and increasing the fuel flow to the engine during transition from the scheduled core speed to scheduled fan speed of the engine to effect a smooth and continuous transition from the core speed to the fan speed and vice-versa. A signal is generated to open and close a valve system to augment and decrease the fuel flow in response to sensing different throttle lever (22) angles.
