A digital twin method for civil aircraft power distribution system based on Unity3D and Simulink

Abstract

Abstract In recent years, digital twin technology has attracted more and more attention from experts and scholars. At present, the application of digital twins mainly focuses on the section assembly and equipment installation of the aviation department, but the practice of digital twins for aircraft signals, internal mechanisms, process flow, and so on is less and more difficult. In addition, for the power distribution system of civil aircraft, real-time monitoring of fault detection and health management and other technical means still have great space for development. Real-time acquisition of power distribution system data of assembly lines and its data during flight is a problem waiting to be solved in the aviation industry. Based on this, this paper takes the power distribution system of a certain type of civil aircraft as an example to accomplish the research on the digital twin technology of the power distribution system of civil aircraft, realizing the information, intelligent, and dynamic scene monitoring of the power distribution network of the plane.
