PROPELLER GOVERNOR CONTROL FOR TURBOPROP ENGINES

摘要

To prevent propeller overshoot, a propeller governor control (18, 20, 34) modifies a speed command issued to the speed setpoint actuator of a propeller governor. The control (34) establishes a false setpoint that causes the propeller governor to change pitch before the propeller reaches the speed ordered by the speed command. The propeller governor control (20) also compensates for small calibration errors in the propeller governor.
