Modeling and simulation of aircraft fuel system under the framework of electromechanical integrated management

A fuel system simulation platform for a certain aircraft was built by Simulink under the framework of electromechanical integrated management. The principle and realization of each subsystem of simulation platform were expounded. This platform has achieved the basic functions of fuel system including pressure fuelling, engines oil supply and cross oil supply. The fuel oil temperature of different flight stages was simulated by adopting the thermal time constant calculation method. Electrical fault characteristics of the oil pump were simulated and analyzed by modeling method. Test results show that fuel system simulation platform can effectively achieve the actual fuel system features and provide favorable support for optimization of aircraft fuel system in the electromechanical integrated management and for the designs of fault diagnosis and fault tolerance as well.
