FADEC System Design For The Aero Engine Of A High Altitude And Long Endurance UAV

This thesis is from APTD (Aero Propulsion Test and Demonstration) project which is supported by COSTIND (Commission of Science Technology and Industry for Nation Defense) . **Engine is designed on the base of WS**Engine by changing some components to satisfy the demands of the high altitude long endurance UAV (Unmanned Aerial Vehicle) .The control system plays a significant role in the whole parts of an engine. The original control system of **Engine, which is a mechanical and hydraulic control system, has been analyzed, and the FADEC system is designed on the same principle.The main content of this thesis are following:1. The primary blue print of the FADEC (Full Authority Digital Electric Controller ) system has been established, including software and hardware;2. All of functions which the UAV required to FADEC have been designed;3. The fuel cell of the original engine has been changed to suit FADEC system;4. To reach the special needs of UAV, some key techniques, such as auto PLA, communication between FADEC and flying control system, reliability design and so on.The project has been ratified by APTD professors in Jan 2006.
