Aiming to a certain type of FADEC-controlled turbo-fan engine as the research object,in combi-nation with the scientific research practice and relevant reference literature,this paper analyses the necessity for construction of semi-physical simulation test system as well as the demand for the architecture and test of engine control system;it also introduces the general design thought and scheme of semi-physical simulation test system and proposes the designs on rotation speed source system,transmission system and load simulation system and so on.
