CONTROL SYSTEM FOR AN AIRCRAFT PROPELLER DRIVE

摘要

The invention relates to a control system for an aircraft propeller drive for controlling the power of a diesel engine (2) by means of a accelerator (7) and a control module (8), and for controlling the speed of the aircraft propeller (4) which can be controlled by a propeller blade control valve (6) and which is connected to the diesel engine (2) by means of a drive train (3). Said control module comprises a totally digital power unit regulator (8) integrating a closed control circuit which is connected to the accelerator for controlling the power and to the propeller blade control valve for controlling the speed of the propeller. Said control circuit compares the desired value based on the position of the accelerator and the measured actual value of the engine speed and controls the propeller blade control valve (6) based on the determined differential speed, and automatically adapts the propeller speed to the engine power predetermined by the position of the accelerator. The control system has one lever allowing the pilot to be discharged and the redundant control system requires a reduced number of components.
