Abstract: In order to fulfill the semi-physical test of a digital engine controller, this paper develops aero-thermodynamic models of the engine’s components using VC++ language according to the engine’s aerodynamic arrangement, the geometry and the component’s test characteristics. Thorough consideration is given to the independency of each component and the interaction of aero-thermodynamic parameters of flow-path components in process of constructing classes, to the extent that the component model can represent the real status of the engine working in transient process calculation as well as can be easily connected. Friendly user interface is developed. The simulation results show that the platform has good efficiency and precision.
