Study on Propeller Speed Governing System of Typical FADEC Aviation Piston Engine
The AE300 engine produced by Austro Engine from Austria,which powers a variety of Diamond family aircraft,is a typical FADEC aviation piston engine using the electronic engine control unit(EECU),and is the main piston engine used in global general aviation.The AE300 engine is equipped with a standard electronically regulated hydraulic governor system,which offers significant operating reaction time advantages over hydraulic servo systems equipped with pressure relief valve and solenoid valves.This paper takes AE300 engine propeller governor system as the research object and studies the aspects of design principle,operation characteristics,typical malfunctions and so on,to provide reference for the designers and users of typical FADEC aviation piston engine propeller governor system.
